Description

The invention relates to a food: internal boilers with indirect controlled heating, made in the form of a double-walled vessel, with a combustion chamber located under it, formed by the steam-water jacket of the boiler.

The known solid fuel boilers of this type do not allow the required process to regulate the heating of the cooking vessel due to the high inertia of the furnace, which leads to unproductive expenditure of fuel for unwanted production of secondary steam in the cooking vessel and reduces the quality of the prepared food.

In the food boiler described below, this disadvantage is eliminated by the fact that its steam pipe to the cutting chamber forming the combustion chamber is separated from the jacket of the cooking vessel by a wall and communicates with it only by the steam line and the condensate line. which are equipped with valves. Due to this, the steam boiler boiler jacket can be used as a group steam generator serving non-coke .ijbKo steam appliances, which allows a significant increase in the efficiency. They should be free from the fireboxes that would be required by these apparatuses when using a boiler with a non-detachable steam-water jacket.

When water is boiled in the boiler jacket, the cooking vessel is a deaerator.

The water level in the boiler's water jacket is low enough that it allows it to work without nutrient flow, according to the scheme with natural circulation.

A feature of the described pip-boiling boiler is also the fact that the concentric shells forming its steam-water jacket are interconnected in the lower part with circulation tubes to increase the reliable circulation of water, and to regulate the heat output of the furnace the grate is equipped with rotary valves , which can reduce ° e live section.

In order to increase i the heating surface, the steam pipe on} the jacket of the boiler is fitted with a welded: nipper shaped tube.

FIG. Figures 1 and 2 schematically show the longitudinal and non-rigeous aspects of a begging bar; in fig. 3-s. Scheme of its use as a submersible steam generator.

The kote.ch consists of a cooking vessel / with a nasal shirt 5 and a wire-mounted plane of the steam generator 3. The steam generator is separated from the jacket by a wall 4 II and is connected to it by the conduit J and the condensate conduit 6.

The race chamber of the boiler is formed by an internal coaxial heater 7. in the lower part of which is a rational radio spinning net 8. consisting of two nods. with dv.chg povorotnpgi cast-iron ambus. Junky 9.

The inner ring heater 7 is connected with the outer one.1 10 with the help of three nicircation tubes // and has curved narnest-like tubes 12 placed in a gas flue 13.

The active part of the back lattice is separated from its inactive part by the incendiary catfish 14, which doesn’t suppose that they are laid on a furious fire tower.

Powering the steam generator iroizvo; 1its water through the valve 15.

The racing gases exit into the co-flue gas duct 13 through the window 16 and with two socks and go into the chimney 17 and further into the chimney.

The steam generator and the digester are insulated 18.

The main steam generating boiler is installed on the same floor as the leveling devices 19 connected to it or is located on the floor below.

From the steam volume of the steam generator of the boiler / there is a distribution steam line 5, to which various oil ay and arate are connected.

On each branch of the distribution of the People's Directorate installed shut-off valve 20.

The condensate is returned to the steam generator of the boiler 1 via the return line 6, which has a stop valve 21 for each appliance.

PREDMETA and about it and her

1. Fire niche cat.-i with a water jacket, made in the form of a double-walled cooking vessel, with a thin chamber centrally located in its lower part, with an annular gas duct formed by the concentric water-carrying walls of a steam wall, t, 4 and And with the fact that, in order to regulate the heating of the cooking vessel of the boiler, as well as to supply steam for other steam-powered boilers that are connected to the wire section of the boiler, it’s separated by O1 of the steam bath. wall and communicates with drink on the conduit and kopdensatoprovod, with installed on them shut-off venti. NPM.

2. Fire food kettle of claim 1, characterized in that, in order to ensure the ordered circulation of the steam-water mixture in the steam-water jacket of the boiler, its short-wall walls are connected in the lower part with circulation pipes,
