SU38956A1 - Gas generator for firewood and peat - Google Patents

Description

In existing gas generators with reversed gas flow and with preheating of the fuel being processed due to heat, waste gases are used by jacketed shafts consisting of several links and devices in the upper part of the shaft for removal of water vapor.

The proposed gas generator is intended to gasify a low-calorie fuel with a high water content of volatiles under the conditions of bulk and weight portability of the entire installation.

In FIG. 1 is a front view of the gas generator; FIG. 2 is a vertical section of it.

The proposed gas generator, made of the pnmnillimetric iron, is a shaft consisting of several parts: link 1, which serves to dry the fuel and remove water vapor, links 29 and 2, designed for dry distillation of fuel, Even 3 with ash pit, where

There is a combustion of the core in the main gas generating process and the decomposition of water vapor and dry distillation products. The individual parts of the shaft are flanged together by bolts or welding; between the flanges for bolting laid asbestos gaskets. Peat enters the gas generator from the bunker 5 by lowering the cone 6. The bunker 5 is separated from the external environment by a hermetically closed lid 7. Water vapor released in the chamber comes under the cap 8 and is discharged through pipes 9-9 from the generator shaft. Peat released in mine I from most of the water enters chamber 29, where it is subjected to dry distillation. Chamber 29 has louvres 10-10 for supplying air in case there is a need to work with a double combustion zone and to conduct the entire work of the generator at a forced pace. The separation of dry distillation products takes place in chamber 2, and the distillates themselves and the remaining coal go into chamber 3, where they are subjected to a final gas treatment to the generator gas. Chamber 3 has a P-I blind for supplying air; a grate 12 is placed in the conical part of the chamber to maintain a layer of fuel in the generator; Below is a gaseous pipe 13 with discharge pipes 14. Gas from the lower part of the generator goes through pipes 14-14 to the outer jacket of link 2 of the shaft, where it gives an excess of its physical heat to shaft 2 and passes through pipes 15-15 to the external shirt of link 1 of the mine where it is further cooled, after which the gas with a temperature of 200-300 ° through pipes 16-16 is led to the engine. The purpose of the shirts at links 1 and 2 of the mine is that the gases entering them give back to the material being processed some of the physical heat, cooling themselves, and on the other hand these shirts are non-collecting chambers.

If, for one reason or another, the heat of gases cannot be used in the bottom 1, and the degree of its transfer through the walls of the shafts, the heat required for the processes occurring in them can be obtained by burning part of the fuel in the upper part of the shaft 2, Moreover, the direction of the heat currents up or down of the generator is regulated by a ventclock 17, standing on the gas-suction pipe 18, connected to the leveling pipes 9-9 using the coil 9a n of the V-shaped pipe 9b. The same amount of steam is also regulated by the amount of steam removed from link 1 of the shaft.

The air required for combustion is sucked in by its engine through the fan 19 and through pipe 20 goes to the taps 21-21 connected by annular space to the combustion zones. The air supply for each zone is carried out in two places of its horizontal section in order to avoid one-sided heating, and in addition, the amount of air entering one or another combustion zone and their individual points is regulated by shut-off valves.

In order to avoid the generator running too hot, the node from the tank 22 through the water line 23 is introduced into the outer jackets of the burning zones. The tank is also a cooler for condensing water vapor leaving the shaft link 1.

The subject of the patent.

Gas generator for firewood and peat with a reverse current of gases, using the heat of exhaust gases to heat the fuel, having a shaft composed of separate links, surrounded by a jacket, and equipped with a device for draining water vapor from the upper part of the shaft, characterized in that the jacket surrounding the shaft the annular chambers 30, 31, 32, 33 (Fig. 2) are divided into corresponding generator zones, of which chambers 30 and 32, corresponding to the complete gasification zones 3 and the upper part of the dry distillation zone 29, are connected via a tap 21 with the duct 20 and through a louver devices. 11 and 10 by the cavity, the chamber 31, corresponding to the lower part 2 of the dry distillation zone, is connected by means of a gas pipeline 14 to a gas collecting pipe 15 with a chamber 33 corresponding to the drying zone 1 n provided with a tap 16 for gas.
