Uppfinnare: M. M. den Boer. Inventor: M. M. den Boer.

Prioritet begard frein den 14 septentber 1045 (Nederliinderna). Priority was given on 14 September 1045 (Nederliinderna).

FOreliggande uppfinning avser en varmvattenbakugn, uppvarmd medelst anguppvarmningsror, i -vilken forbranningsprodukterna bringas att cirkulera, d. v. s. en bakugn, vilken en del av farbranningsprodukterna le-des tillbaka till utrymmet ovanfor fyren. The present invention relates to a hot water baking oven, heated by means of steam heating tubes, in which the combustion products are circulated, i.e. a baking oven, which part of the combustion products is led back to the space above the lighthouse.

I enlighet med uppfinningen ar mellan bakrummets bakre vagg och en i anslutning hartill vertikalt anordnad rokgaskanal anordnad en kanal, som i sin Owe ande genom kanaler under ugnens tak star i forbindelse med rorgaskanalen i dennas Owe ande och vid sin nedre uncle genom ihaliga sidovaggar i eldstaden star i forbindelse med sugsidan till en flakt, vats trycksida dr forbunden med tva kanaler, av vilka den ena leder till -ett utlopp till atmosfaren och den andra till utrymmet ovanfor rosten, varvid inloppen till dessa kanaler dro anordnade att kunna kontrolleras medelst ett spj all eller liknande. According to the invention, between the rear cradle of the rear compartment and a flue gas duct arranged vertically adjacent thereto, a duct is arranged, which in its Owe spirit through channels under the roof of the furnace communicates with the rudder gas duct in its Owe spirit and at its lower uncle through hollow side cracks in the fireplace is connected to the suction side of a flake, the pressure side of which is connected to two channels, one of which leads to an outlet to the atmosphere and the other to the space above the grate, the inlets to these channels being arranged to be controlled by means of a spigot. or similar.

Utom de kanda fordelarna med ett tvangsstyrt drag, d. v. s. latt astadkommen reglering av forbranningen och cirkulationen samt franyaron av en hog skorsten, uppyisar ugnen enligt uppfinningen aven den fordelen, att hastigheten och volymen ph de gaser, som cirkulera i den kanal, i vilken rorens andar aro belagna, kan taus, sd att varmeoverforingen till andra delar kan astadkommas huvudsakligen medelst ledning. Pd grund harav kan man utesluta de tjocka vaggarna av varmeabsorberande tegel, genom vilka varmet i de kanda varmvattenugnarna huvudsakligen maste overforas genom straining, sd att man kan undvika den olagenheten, att under en viloperiod praktiskt taget allt varmet i den ackumulerande massan yid slutet av en bakningsperiod gar f8rlorat. In addition to the known advantages of a forced draft, i.e. easily achieved control of the combustion and circulation and franyaron of a high chimney, the furnace according to the invention also has the advantage that the speed and volume of the gases circulating in the duct in which the spirits of the rudder aro belagna, can be silent, sd that the heat transfer to other parts can be accomplished mainly by line. Due to this, the thick rocks of heat-absorbing bricks can be excluded, through which the heat in the known hot water furnaces must mainly be transferred by straining, so that one can avoid the inconvenience that during a rest period practically all the heat in the accumulating mass yid the end of a baking period is lost.

Beroende p det satt, pa vilket varmet Overfores och cirkuleras, liksom pa det faktum, att rokgaserna yid lagre temperatur an en gang komma in i cirkulationen utefter tuberna vid en anordning enligt uppfinningen minskas mojligheterna till lokal upphettning av tubandarna, sd att a.ven riskerna f Or explosion i tuberna bli mycket obetydliga. Depending on the way in which the heat is transferred and circulated, as well as on the fact that the flue gases at a lower temperature once enter the circulation along the tubes in a device according to the invention, the possibilities for local heating of the tubands are reduced, so that even the risks f Or explosion in the tubes become very insignificant.

Av samma orsak kan man aven anvanda varmvattentuber med mindre yttre diameter, yid vilka yarineoverforingen genom ledning okas, vilket utgor ytterligare en orsak till att en annu lagre rokgastemperatur kan vara tillracklig. For the same reason, it is also possible to use hot water tubes with a smaller outer diameter, in which the yarine transfer by line is increased, which is another reason why an even lower flue gas temperature may be sufficient.

Denna lagre temperatur är naturligtvis till avsevard fordel fOr bakugnens livslangd, medan det samtidigt blir mojligt att utfora den i stal. This lower temperature is of course a significant advantage for the service life of the oven, while at the same time it becomes possible to perform it in steel.

Genom att enligt uppfinningen kanalen melIan bakrummets bakre vagg och den vertikala rokgaskanalen Yid sin nedre ande genom eldstadens ihaliga sidovaggar forbindas med sugsidan till en flakt, vars trycksida ar forbunden dels med skorstenen, dels med en kanal, corn leder till utrymmet ovanfor fyren, samt genom att inloppen till dessa forbindelser goras samtidigt .eller separat reglerbara medelst ett spjall eller liknande, komma de vaggar, som utsattas for hettan fran fyren, att kylas under samtidigt tillvaratagande av varmet. Harigenom okas avsevart anordningens varmeelconomi. According to the invention, the duct between the rear cradle of the rear compartment and the vertical flue gas duct Yid connects its lower end through the hollow side walls of the fireplace to the suction side to a flap, the pressure side of which is connected partly to the chimney, partly to a duct leading to the space above the lighthouse that the inlets to these connections are made simultaneously, or separately controllable by means of a damper or the like, the cradles which are exposed to the heat from the lighthouse will be cooled while simultaneously taking advantage of the heat. This significantly increases the device's heating electricity economy.

Enligt uppfinningen kan dessutom flakten anbringas i utrymmet mellan ugnens underrede och eldstadens askrum, varvid kanalen till skorstenen .och kanalen till utrymmet ovanfor fyren kunna utformas i eldstadens ihdliga, bakre vagg, varigenom eldstadens -vaggar aven komma att kylas yid denna sida och det ackumulerade yarmet att ater anvandas for overhettning. According to the invention, in addition, the flush can be applied in the space between the furnace chassis and the fireplace ash chamber, whereby the channel to the chimney and the channel to the space above the lighthouse can be formed in the fireplace's continuous rear cradle, whereby the fireplace cradles will also be cooled by this side and the accumulated arm. to be used again for overheating.

Uppfinningen hänfOr sig vida-re till en anordning, medelst vilken volymen pa de rokgaser, som avledas och iterforas till utrymmet ovanfor fyren, kan regieras pa ett enkelt satt medelst ett spjall. The invention further relates to a device by means of which the volume of the flue gases which are diverted and iterated to the space above the lighthouse can be controlled in a simple manner by means of a damper.
