Opfindelsen angâr et infrar0dt opvarmningsanlæg omfat-tende et varmer0r og flere forbrændingsindretninger fordelt langs varmer0rets længde for at tilf0re varme 5 gasser til det indre af varmer0ret for at fâ varmer0ret til at udsende indfrar0d strâling fra sin overflade, og i hvilket anlæg hver forbrændingsindretning indeholder en brænderenhed, der er placeret i varmer0ret, og en kontrol-box, der har âbninger for tilf0rsel til brænderenheden af 10 den korrekte mængde luft for fuldstændig forbrænding af brændstoffet, der tilf0res brænderenheden, og hvor der findes en vakuumpumpe, der forârsager, at luften str0mmer gennem varmer0ret.The invention relates to an infrared heating system comprising a heating pipe and several combustion devices distributed along the length of the heating pipe to supply hot gases to the interior of the heating pipe to cause the heating pipe to emit infrared radiation from its surface, and in which installation each combustion unit contains located in the heating pipe and a control box which has openings for supply to the burner unit of 10 the correct amount of air for complete combustion of the fuel supplied to the burner unit and where there is a vacuum pump which causes the air to flow through varmer0ret.
Infrar0d strâling opvarmer genstande direkte med et minimalt 15 tab af varmeenergi til luften mellem varmeapparatet og en genstand. Genstanden, der har absorberet den infrar0de strâling, kan lede noget af varmen fra overfladen til det indre af genstandens legeme og genudstrâle resten, sâledes at den bliver en sekundær kilde af infrar0d strâling. Den genudstrâ-20 lede varmeenergi vil derefter blive absorberet af andre kol-dere overflader eller af den omgivende luft.Infrared radiation heats objects directly with a minimum of 15 loss of heat energy to the air between the heater and an object. The object which has absorbed the infrared radiation can direct some of the heat from the surface to the interior of the object's body and radiate the remainder to become a secondary source of infrared radiation. The radiated heat energy will then be absorbed by other cold surfaces or by the surrounding air.
St0rrelsen af varmetab til den omgivende luft, hulrum og til frembringelse af træk er derfor ubetydelig for infrar0de varmeanlæg.Therefore, the amount of heat loss to the ambient air, voids and to generate features is negligible for infrared heating systems.
25 Det er kendt at anvende infrar0d strâling frembragt ved passage af varme gasser gennem et varmer0r, f.eks. vil der bræn-de en luft-gasblanding i r0ret for at opvarme beboelser og arbejdspladser, f.eks. forretninger, kontorer og fabri-ker.It is known to use infrared radiation produced by passing hot gases through a heating tube, e.g. for example, an air-gas mixture will be burned in the pipe to heat homes and workplaces, e.g. shops, offices and factories.
30 Indtil for fâ âr siden kunne infrar0d strâling imidlertid kun anvendes effektivt til at frembringe h0j temperatur, som f.eks. kræves i bageovne. Sâdanne anlæg anvendte som varmekilde kun det 0vre omrâde af det infrar0de spek-trum. Direkte opvarmningsanlæg for boliger og arbejds- 2However, until a few years ago, infrared radiation could only be used effectively to produce high temperatures, such as required in baking ovens. Such systems used as the heat source only the upper area of the infrared spectrum. Direct heating systems for housing and work 2

pladser var pâ det tidspunkt meget ineffektive og ydnytte-de kun lidt om overhovedet noget af den frembragte infra-r0de strâling til direkte at opvarme genstande.At that time, seats were very inefficient and useless - they had little if any of the infrared radiation produced to directly heat objects.
5 Senere har det ved at tilvejebringe styreorganer for til-f0rsel af de rigtige forhold af luft og gas til frembrin-gelse af en effektiv forbrændingsblanding og ved at for-binde styreorganerne til flere forbrændingsindretninger i forbindende r0r anbragt i rummet, der skal opvarmes, og 10 ved at drive opvarmningsanlægget ved et lidt mindre tryk end 1 atmosfære været muligt at anvende mere af den infrar0de strâling udsendt fra væggene af forbindelses-r0rene for direkte at opvarme genstande. Som f0lge af tilstedeværelsen i forbindelsesr0rene af forbrændings-15 produkter, der er frembragt af forudgâende forbrændingsindretninger, kan der imidlertid være utilstrækkeligt oxygen til at udvirke fuldstændig forbrænding og sâledes forhindre effektiv drift af forbrændingsindretningerne.Later, by providing control means for supplying the proper ratios of air and gas to produce an efficient combustion mixture, and by connecting the control means to multiple combustion devices in connecting tubes arranged in the space to be heated, and 10, by operating the heater at a slightly less pressure than 1 atmosphere, it has been possible to use more of the infrared radiation emitted from the walls of the connecting tubes to directly heat objects. However, due to the presence in the connection tubes of combustion products produced by prior combustion devices, there may be insufficient oxygen to effect complete combustion and thus prevent efficient operation of the combustion devices.
I DE-patentskrift nr. 3.001.635 beskrives en fremgangs-20 mâde til opvarmning af en kostald, hvor et varmer0r langs sin længde er forsynet med to forbrændingsaggregater, der hver har en brænder, der rager ind i r0ret. I det nævnte patentskrift beskrives, at primærluften tilf0res for-brændingsaggregatet og brænderen ved hjælp af en pumpe ved 25 den ene ende af r0ret, hvor denne pumpe ogsâ muligg0r blanding af primærluften og brændstofgassen. Den ende af r0ret, der er fjernest fra pumpen, er âben for at tillade at luft kan komme ind i anlægget. Der findes imidlertid ingen beskrivelse af, at forbrændingsaggregatet er kon-30 strueret pâ en sâdan mâde, at det tilf0rer en sâdan mængde primærluft til brænderne, at der sker en fuldstændig forbrænding af det brændstof, der sendes brænderne. Ovennævnte patentskrift beskriver heller ikke, at pumpens funktion er sâledes, at den s0rger for, at der sendes et 35 overskud, eller en forudbestemt mængde af luft gennem r0ret for at sikre en fuldstændig forbrænding af det brændstof, der sendes til aile brænderne i r0ret.DE Patent Specification No. 3,001,635 discloses a method of heating a cost bar where a heating pipe is provided along its length with two combustion units, each having a burner projecting into the pipe. The patent specification discloses that the primary air is supplied to the combustion unit and the burner by means of a pump at one end of the pipe, where this pump also enables mixing of the primary air and the fuel gas. The end of the pipe that is farthest from the pump is open to allow air to enter the system. However, there is no description that the combustion unit is constructed in such a way that it supplies such a quantity of primary air to the burners that a complete combustion of the fuel sent to the burners is effected. Nor does the aforementioned patent specification disclose that the operation of the pump is such as to cause an excess or a predetermined amount of air to pass through the tube to ensure complete combustion of the fuel sent to all the burners in the tube.

Opfindelsen har til formàl at angive et infrar0dt opvarm-ningsanlæg, der omfatter et varmer0r og flere forbræn-dingsindretninger fordelt langs længden af varmer0ret for 5 at tilf0re varme gasser til det indre af r0ret, som der-ved fâs til at udsende infrar0d strâling fra sin overflade, og som sikrer en fuldstændig forbrænding af det brændstof, der sendes til aile forbrændingsindretningerne, der er anbragt langs r0ret.The invention has for its object to provide an infrared heating system comprising a heating tube and several combustion devices distributed along the length of the heating tube to supply hot gases to the interior of the tube, which is thereby obtained to emit infrared radiation from its surface, which ensures complete combustion of the fuel sent to all combustion devices located along the pipe.
10 Dette formâl opnâs if01ge opfindelsen ved, at der findes en vakuumpumpe, der er indstillet sâledes, at der fore-kommer et overskud af luftstr0m gennem varmer0ret ved brug af anlægget, sâledes at hver af de i sérié anbragte brænderenheder kan fungere inden i varmer0ret med en fuld-15 stændig forbrænding af brændstoffet i en atmosfære, der indeholder forbrændingsgasserne fra enhver opstrpms placeret brænderenhed, og ved at der findes et enkelt indtillingsorgan, hvorved varmekapaciteten i anlægget kan indstilles, eller hvorved der kan kompenseres for foran-20 dringer i brændstoffets karakteristik, hvor de nævnte indstillingsorganer indeholder et spjæld, der er placeret i varmer0ret nedstr0ms i forhold til brænderenhederne.This object is achieved according to the invention by providing a vacuum pump which is set so that there is an excess of air flow through the heating pipe using the plant, so that each of the burner units located in the series can function within the heating pipe with a full-time continuous combustion of the fuel in an atmosphere containing the combustion gases of any upstream burner unit, and by providing a single adjusting means for adjusting the heat capacity of the plant or for compensating for changes in fuel characteristics , wherein said adjusting means includes a damper located in the downstream heat pipe relative to the burner units.
Et infrar0dt opvarmningsanlæg if01ge opfindelsen har sâledes den fordel, at en forbrændingsenhed, der i sérié 25 med andre forbrændingsenheder arbejder i en atmosfære indeholdende forbrændingsprodukter fra de andre brændere, altid kan afgive den totale forbrændingsvarme uden forringelse af flammen.Thus, an infrared heating system according to the invention has the advantage that a combustion unit operating in series 25 with other combustion units in an atmosphere containing combustion products from the other burners can always give off the total combustion heat without reducing the flame.
Hver forbrændingsindretning i rækken tilvejebringer for-30 trinsvis den samme varmeeffekt og kan if0lge opfindelsen forud justeres pâ en fabrik til at afgive denne effekt.Each combustion device in the array preferably provides the same heat effect and, according to the invention, can be pre-adjusted in a factory to deliver this effect.
Gas-luftforholdet kan if01ge opfindelsen være forud indstillet og opretholdt under variationer i de samlede træk- og temperaturforhold.According to the invention, the gas-air ratio can be preset and maintained under variations in overall drag and temperature conditions.

Et styreorgan h0rer i en foretrukken udf0relsesform for anlægget til hver forbrændingsindretning og regulerer mængden af den tilf0rte gas.A control means in a preferred embodiment of the system for each combustion device regulates the amount of gas supplied.
5 Der fIndes hensigtsmæssigt et enkelt justeringsargan, der tillader justering af anlæggets varmekapacitet, eller som muligg0r kompensering af ændringer i brændslets karakte-ristikker.5 Conveniently, a single adjusting device is provided which allows adjustment of the heat capacity of the plant or which allows for compensation of changes in the characteristics of the fuel.
Nâr der anvendes et luftformigt brændsel, kan der sâledes 10 for en ændring i dette kompenseres ved en simpel juste-ring, der tillader opretholdelse af den krævede totale varmeeffekt og det forud indstillede gas-luftforhold.Thus, when an gaseous fuel is used, 10 for a change in it can be compensated by a simple adjustment allowing the maintenance of the required total heat power and the preset gas-air ratio.
Hensigtsmæssigt h0rer der if01ge opfindelsen reflekteren-de midler til en eller flere dele af et varmer0r for at 15 rette den derved frembragte strâlevarmeenergi til rummet, der skal opvarmes. Sædvanligvis omfatter de reflekterende midler en langstrakt reflektor anbragt aksialt over en del af varmer0ret for at rette strâlevarmeenergi nedad fra r0rdelen til rummet, der skal opvarmes, og et langstrakt, 20 reflekterende skjold bâret aksialt under r0rdelen for at afb0je en del af den fra rordelen udstrâlede strâlevarmeenergi opad mod reflektoren. Sâdanne reflekterende midler medf0rer den fordel, at varmeenergien kan rettes kun mod det rum, der kræves opvarmet, og sâledes forhindrer eller 25 reducerer tab.Conveniently, according to the invention, reflected means belong to one or more parts of a heating pipe to direct the radiant heat energy produced thereby to the space to be heated. Typically, the reflecting means comprise an elongated reflector disposed axially over a portion of the heating pipe to direct radiant heat energy downward from the pipe portion to the space to be heated, and an elongated, reflective shield carried axially below the pipe portion to deflect a portion of the radiated portion from the pipe portion. radiant heat energy up towards the reflector. Such reflective means have the advantage that the heat energy can be directed only to the space required for heating, thus preventing or reducing losses.
En eller flere dele af et varmer0r kan if01ge opfindelsen være forsynet med isolerende midler for at regulere udstrâlingen af strâlevarmeenergi, hvilke isolerende midler sædvanligvis omfatter et isolerende r0r indsat i en 30 del af et varmer0r for at ber0re den indre overflade af dette. Anvendelsen af sâdanne isolerende midler tillader omstilling af strâlevarmeenergi, der om n0dvendigt skal reguleres, og reducerer sâledes muligheden for overopvarmning af et bestemt rum, der skal opvarmes.According to the invention, one or more parts of a heating pipe may be provided with insulating means for regulating the radiation of radiant heat energy, which insulating agents usually comprise an insulating pipe inserted into a part of a heating pipe to touch the inner surface thereof. The use of such insulating agents allows the conversion of radiant heat energy to be regulated, if necessary, and thus reduces the possibility of overheating a particular room to be heated.

Fig. 1 viser skematisk et opvarmningsanlæg omfattende 20 flere r0rstrenge med forbindelsesr0r B og forbrændings-indretninger C og forbundet gennem samler0r B til en vakuumpumpe A. Ikke-justerbare endeventiler D er anbragt ved de frie ender af r0rstrengene for at tillade en styret mængde af overskudsluft af str0mme ind i r0rsystemet.FIG. 1 schematically shows a heating system comprising 20 more pipe strings with connecting pipes B and combustion devices C and connected through collector pipe B to a vacuum pump A. Non-adjustable end valves D are arranged at the free ends of the pipe strings to allow a controlled amount of excess air of current into the pipe system.
25 Vakuumpumpen A trækker luft-gasblandingen gennem r0rene og tillader en styret reduktion af trykket til lige under atmo-sfæretryk.The vacuum pump A draws the air-gas mixture through the tubes and allows a controlled reduction of the pressure to just below atmospheric pressure.
Et spjæld E findes i hver r0rstreng lige f0r dets forbindel-se med en anden streng for at regulere sugevirkningen af 30 vakuumpumpen A og g0re hver streng uafhængig af sugevirkningen i det 0vrige af anlægget.A damper E is provided in each pipe string just before its connection with a different string to regulate the suction effect of the vacuum pump A and make each string independent of the suction effect in the rest of the system.

For at tilpasse variationer i og kombinationer af forbræn- 5 dingsindretningens brændselsforhold er begrebet den "ækvi- valente brænder" til beregning af det rigtige gas-luftfor- hold blevet erstattet af en metode med str0mningsenheder, hvor en str0mningsenhed λ er den mængde luft, der kræves til 3 forbrænding af 235 cm /s naturgas, hvilket er ækvivalent 10 med 10.550,65 kJ/h =2,93 kW.In order to adjust variations in combinations of combustion device fuel ratios, the concept of the "equivalent burner" for calculating the correct gas-air ratio has been replaced by a flow unit method where a flow unit λ is the amount of air that required for 3 combustion of 235 cm / s of natural gas, which is equivalent to 10 with 10,550.65 kJ / h = 2.93 kW.
For at tilvejebringe en fuldstændig forbrænding af naturgas, som hovedsagelig bestâr af methan, kræves et gas-luftforhold 3 pâ 1:2, hvilket giver λ = 787 cm /s.In order to provide a complete combustion of natural gas, consisting mainly of methane, a gas-to-air ratio 3 of 1: 2 is required, giving λ = 787 cm / s.
Som vist i fig. 1 kræver hver forbrændingsindretning C 6 λ 3 15 eller 1,7 m /h luft, medens hver endeventil D er konstrue- 3 ret til at tillade 12 λ eller 3,4 m /h at trænge ind i appa-ratet.As shown in FIG. 1, each combustion device C 6 λ 3 requires 15 or 1.7 m / h of air, while each end valve D is designed to allow 12 λ or 3.4 m / h to enter the apparatus.

Men der kan naturligvis anvendes 25 andre metoder til at forbinde brænderenheden i en r0rstreng.The burner assembly comprises a tube whose ends 17 have internal threads which are screwed to ends 21 and 21 'with external threads of connecting tubes 18 and 18' to mount the burner in a tubing string. But of course, 25 other methods can be used to connect the burner unit in a pipe string.
Gas kommer ind i kontrolboksen F ved hjælp af et gasr0r 1, og en regulator 3 sikrer, at den rigtige mængde gas tilf0-res anlæggat.

A wall 14 in the duct 11 protects the wall flush in the spark chamber 23 for traits caused by air passing through the duct 11.
En buet bagvæg 15 i kanalen 11 afskærmer tilsvarende bræn-15 dergitteret 16 fra str0mmen af forbrændingsgasser, der passerer gennem forbindelsesr0ret 18.A curved rear wall 15 in channel 11 similarly shields the burner lattice 16 from the stream of combustion gases passing through the connecting pipe 18.

Til at begynde med trækkes gas gennem styreventilen 5 ind i vâgeblusr0ret 12 og blandes med luft, der kommer ind i r0ret 12 gennem luftâbningen 8.Initially, gas is drawn through the control valve 5 into the airless tube 12 and mixed with air entering the tube 12 through the air opening 8.
Luft-gasblandingen passerer gennem en âbning 20 ind i gnist-5 kammeret 23. Et ikke vist varmestyreorgan aktiverer ikke viste, elektriske organer for at fâ kontakter 13 pâ et tænd-r0r 9 til at afgive en gnist. Derefter tændes luft-gasblandingen i kammeret 23.The air-gas mixture passes through an aperture 20 into the spark chamber 23. A heat control means (not shown) activates the electrical means (not shown) to cause contacts 13 on a spark plug 9 to emit a spark. Then the air-gas mixture is turned on in chamber 23.
En ikke vist f0ler detekterer vâgeblusset og fâr hovedven-10 tilen 6 til at âbne. Gas f0res derefter gennem en âbning 10A i kammeret 22 ind i kanalen 11/ og luft suges ind i kanalen 11 ved den af gasstr0mmen frembragte sugevirkning gennem âbningen 10, som er rigtigt dimensioneret for at frembringe den optimale luft-gasblanding.A sensor not shown detects the wall flare and causes the main valve 6 to open. Gas is then passed through an orifice 10A of the chamber 22 into the duct 11 / and air is sucked into the duct 11 by the suction effect produced by the gas stream through the orifice 10 which is properly sized to produce the optimum air-gas mixture.

Forbrændingsgasserne suges gennem r0ret 18' ved virkningen 20 af vakuumpumpen A, hvorved r0ret opvarmes og udstrâler ener-gi i form af infrar0d strâling.The combustion gases are sucked through the pipe 18 'by the action 20 of the vacuum pump A, whereby the pipe is heated and radiates energy in the form of infrared radiation.
Forbrændingsgasser fra éventuelle forudgâende brænderenheder passerer brændergitteret 16 og afb0jes af den buede bagvæg 15 i kanalen 11. Væggen 15 afskærmer sâledes brænderflammen 25 fra forbrændingsgasserne og forhindrer kontaminering af luft-gasblandingen, hvilket ville nedsætte forbrændingseffektivite-ten, og forhindrer ogsâ fiammerne i at blive slukket ved frembragt træk eller mangel pâ oxygen.Combustion gases from any prior burner units pass burner grille 16 and are deflected by the curved rear wall 15 of channel 11. Wall 15 thus shields burner flame 25 from the combustion gases and prevents contamination of the air-gas mixture, which would reduce combustion efficiency and reduce combustion efficiency. by the generation or absence of oxygen.
Vakuumpumpen fjerner forbrændingsgasserne fra anlægget, °9 30 disse r0ggasser passerer derefter ud af beboelsen eller ar-bejdsstedet og udt0mmes i atmosfæren.The vacuum pump removes the combustion gases from the plant. These flue gases then pass out of the dwelling or place of work and are discharged into the atmosphere.

Fig. 3 og 4 viser midler h0rende til en del B' af et r0r B for reflektering af strâleenergien udsendt af denne r0rdel til beboelses- eller arbejdspladsomrâdet, der kræves opvar-met.FIG. 3 and 4 show means belonging to a portion B 'of a tube B for reflecting the radiant energy emitted by this tube to the residential or workplace space required for heating.
5 Som vist omfatter de reflekterende midler en langstrakt re-fléktor 24 af i det væsentlige omvendt W-form i.tværsnit an-bragt over r0rdelen B', sâledes at reflektorens længdeakse er parallel med aksen af r0ret B. Reflektoren 24 er dimen-sioneret til at reflektere strâlevarmeenergi, der strâles 10 opad fra r0rdelen B', ned mod det omrâde, der skal opvarmes.As shown, the reflecting means comprise an elongate reflector 24 of substantially inverted W-shape in cross-section arranged over the pipe portion B 'such that the longitudinal axis of the reflector is parallel to the axis of the pipe B. The reflector 24 is dimensioned for reflecting radiant heat energy radiated upwardly from the pipe portion B 'down towards the area to be heated.
De reflekterende midler omfatter ogsâ et langstrakt strâle-varmeskjold 25 af omvendt V-form i tværsnit ophængt i st0t-tebeslag 26 under r0rdelen B', sâledes at dets længdeakse er parallel med r0raksen. Strâlevarmeskjoldet 25 tjener til 15 at reflektere en del af strâlevarmeenergien, der rettes ned-ad mod r0rdelen B1, til reflektoren 24 for at sikre, at strâlevarmeenergien fordeles mere jævnt over det omrâde, der skal opvarmes.The reflecting means also comprise an elongated inverted V-shaped radiant heat shield 25 suspended in support bracket 26 below the pipe portion B 'such that its longitudinal axis is parallel to the pipe axis. The radiant heat shield 25 serves to reflect a portion of the radiant heat energy directed downwardly to the pipe portion B1 to the reflector 24 to ensure that the radiant heat energy is more evenly distributed over the area to be heated.
Strâleskjoldet 25 kan anvendes lokalt for at reducere strâ-20 leintensiteten umiddelbart under r0ret. Uden de reflekterende midler er strâlevarmeintensiteten st0rst ved et punkt umiddelbart under r0ret B' som f0lge af den omvendte kvadratlov.The beam shield 25 can be used locally to reduce the beam intensity immediately below the tube. Without the reflective means, the radiant heat intensity is greatest at a point immediately below tube B 'as a result of the inverse square law.
Som f0lge af formen og placeringen afbryder strâleskjolet 25 den direkte strâlevarmebane og reflekterer varme tilba-25 ge til reflektoren 24, som genreflekterer strâlevarmen bort fra centerlinien af det udstrâlende r0r.As a result of the shape and location, the jet sheath 25 interrupts the direct radiant heat path and reflects heat returns to the reflector 24, which reflects the radiant heat away from the center line of the radiating tube.
Bâde reflektoren 24 og strâlevarmeskjoldet kan fremstilles af f.eks. 0,7 eller 0,5 mm NATL (TYP)-aluminium og er fra ca. 1,2 til 2,4 m i længde afhængig af kravene. Der kan væ-30 re et eller flere reflekterende midler i anlægget i fig. 1 afhængig af de særlige opvarmningskrav for de omrâder, der skal opvarmes.Both the reflector 24 and the radiant heat shield can be made of e.g. 0.7 or 0.5 mm NATL (TYP) aluminum and is from approx. 1.2 to 2.4 m in length depending on requirements. There may be one or more reflective means in the system of FIG. 1 depending on the specific heating requirements for the areas to be heated.

In the arrangement shown, the insulating tube 27 is made of alumina with a wall thickness of 5 to 10 mm.
10 Det isolerende r0r 27 er indsat i r0rdelen B", sâledes at det ber0rer den indre flade af denne. Det isolerende r0r 27 tillader, at mængden af strâlevarmeenergi, der udsendes fra denne isoleringen indeholdende del af r0ret/kan reduce-re temperaturen af r0ret B pâ dette sted.The insulating tube 27 is inserted into the tube portion B "so that it touches the inner surface thereof. The insulating tube 27 allows the amount of radiant heat energy emitted from this insulation containing part of the tube / to reduce the temperature of the tube. B at this place.
15 Isolerende r0r kan være anbragt forskellige steder i anlæg-get i fig. 1 for at reducere strâletemperaturerne lokalt og sâledes styre strâlevarmeudsendelsen langs r0rene B i an-lsgget og forhindre overopvarmning af omrâder, hvor der kun kræves let opvarmning.15 Insulating tubes may be located at various locations in the system of FIG. 1 to reduce the radiant temperatures locally and thus control the radiant heat emission along tubes B of the plant and prevent overheating of areas where only slight heating is required.
20 Som det ses af fig. 5, kan der i det eller de isolerende r0r 27 i anlsgget være udformet âbninger 28, hvor der pâ ekstremt lokale omrâder kræves h0jere strâlevarmeenergi.20 As seen in FIG. 5, apertures 28 may be provided in the insulating pipe (s) 27 in the installation, where, in extremely local areas, higher radiant heat energy is required.
