Description
Damp- eller hetvannskjeie. Steam or hot water kettle.
Den foreliggende oppfinnelse angår en damp- eller hetvannskjele med strålingsfyrrom og minst en konveksjonsdel som slutter seg til dette i aksial retning og er utført som røkrørsvarmeveksler med et antall røkrør som forløper mellom to endeblikk. The present invention relates to a steam or hot water boiler with a radiation boiler room and at least one convection part which joins this in the axial direction and is designed as a flue heat exchanger with a number of flue pipes extending between two end plates.
Oppfinnelsen befatter seg særlig med utformningen av kjelens deler med sikte på å sikre en effektiv kjøling. The invention is particularly concerned with the design of the boiler's parts with the aim of ensuring efficient cooling.
Det som karakteriserer oppfinnelsen, består i at kjelevannets passasje gjennom konveksjonsdelen på i og for seg kjent måte styres av et antall skjermer anbragt parallelt med endeblikkene, samtidig som avstanden mellom det endeblikk som vender mot fyrrommet, og den nærmeste skjerm er påtagelig mindre enn den innbyrdes avstand mellom skjermene forøvrig. What characterizes the invention is that the passage of the boiler water through the convection section is controlled in a manner known per se by a number of screens placed parallel to the end screens, while the distance between the end screen facing the boiler room and the nearest screen is noticeably smaller than the distance between them distance between the screens otherwise.
Tegningen viser som eksempel en utførelsesform av oppfinnelsen anvendt ved en stående sylindrisk hetvannskjele med sentralt fyrrom og to konveksjonsdeler. The drawing shows, as an example, an embodiment of the invention applied to a standing cylindrical hot water boiler with a central boiler room and two convection parts.
Kjelen består av et sylindrisk fyrrom lo og to konveksjonsdeler som er anbragt i hver sin ende av dette og er betegnet generelt med henholdsvis 11 og 12. I fyrrommets vegg er der montert tre olje- eller gassbrennere 13 som strekker seg stort sett tangentialt i forhold til fyrrommets mantelflate så der frembringes en rotasjon i fyrrommet. Røkgassene unnviker gjennom røkrør 14 i konveksjonsdelene til skorstenstilslutninger 15 og 16, anbragt i henholdsvis øvre og nedre ende av kjelen. Kjelevannet tilføres gjennom en tilslutning 17 i den nedre del av kjelen og forlater denne gjennom en tilslutning 18 i dens øvre del. The boiler consists of a cylindrical boiler room lo and two convection parts which are placed at opposite ends of this and are generally denoted by 11 and 12 respectively. Three oil or gas burners 13 are mounted in the wall of the boiler room which extend largely tangentially in relation to the boiler room's mantle surface so that a rotation is produced in the boiler room. The flue gases escape through flue pipes 14 in the convection parts to the chimney connections 15 and 16, located at the upper and lower ends of the boiler, respectively. The boiler water is supplied through a connection 17 in the lower part of the boiler and leaves it through a connection 18 in its upper part.
Hver av konveksjonsdelene består av en sylindrisk mantel 19 og. to endeblikk 20 og 21. Røkrørene 14 er innvalset eller inn-sveiset i endeblikkene og avstager således disse. Vannmagasinet i konveksjonsdelen er ved skjermer 22, 23 oppdelt i et antall passasjer. Den skjerm 23 som ligger'nærmest det endeblikk 20 som vender mot fyrrommet, ligger i en avstand fra. dette endeblikk betydelig mindre enn den avstand som foreligger mellom på hinannen følgende skjermer i konveksjonsdelen forøvrig. Vannets hastighet i denne passasje blir derved betraktelig øket, noe som fremmer varmeovergangen, samtidig som slike dampblærer som eventuelt dannes langs veggen mot fyrrommet, blir revet effektivt med av vannstrømmen mot utløpet. Each of the convection parts consists of a cylindrical mantle 19 and. two end plates 20 and 21. The flue pipes 14 are rolled or welded into the end plates and thus brace them. The water reservoir in the convection section is divided by screens 22, 23 into a number of passages. The screen 23 which is closest to the end window 20 which faces the boiler room is located at a distance from this end view is significantly less than the distance that exists between successive screens in the convection section otherwise. The speed of the water in this passage is thereby considerably increased, which promotes heat transfer, at the same time that any steam bubbles that may form along the wall towards the boiler room are effectively swept away by the water flow towards the outlet.
Fyrrommet 10 begrenses av vannrør 24. Disse er hensiktsmessig forsynt med flenser og er sammensveiset for å danne en gass-tett vegg. Vannrørene er tilsluttet endeblikkene 20 i en krans utenfor røkrørene, hvorved der kan sikres en effektiv vannsirkula-sjon. The boiler room 10 is limited by water pipes 24. These are appropriately provided with flanges and are welded together to form a gas-tight wall. The water pipes are connected to the end plates 20 in a ring outside the smoke pipes, whereby an efficient water circulation can be ensured.
Oppfinnelsen kan også anvendes ved slike kjeler som bare har en enkelt konveksjonsdel, hensiktsmessig med brennere plasert i taket av fyrrommet. Eventuelt kan man ved den viste brenner-plasering erstatte den øvre konveksjonsdel med et endeparti som er dobbeltvegget, men ikke inneholder røkrør. Kjelen kan også utformes liggende, og skal den anvendes som dampkjele, blir en dampdom tilsluttet utløpet 18. The invention can also be used with such boilers which only have a single convection part, suitably with burners placed in the ceiling of the boiler room. Optionally, with the burner placement shown, the upper convection part can be replaced with an end part that is double-walled, but does not contain smoke pipes. The boiler can also be designed horizontally, and if it is to be used as a steam boiler, a steam boiler is connected to the outlet 18.
