Description

Proposed gas generator

intended for gasification of bituminous fuel with dilution of dry distillation products by passing them through hot coal and cracking pipe.

FIG. 1 of the drawing shows a vertical section of the gas generator, and FIG. 2 shows a section along the line AB of FIG. one.

The gas generator consists of a series of vertical cylinders 2, adjacent to the common hermetically sealed bunker 1, and from the bottom to the box 3. The latter is divided into two parts by a horizontal grille 15 and is connected to a coil 4 located around the burners 7.

The operation of the generator is as follows. Fine-grained or pulverized fuel is loaded into the hopper / and the cylinders 2 located on. circle. The latter are heated outside, and the fuel contained therein undergoes a process of dry distillation. The resulting coke goes down into box 3 and is located on the grate. Water vapor of fuel, and in case of insufficient humidity and vapor of specially planted water, passage through

red-hot coke reacts with it according to the equation L0 + C CO - {- Po, converting all the coke carbon into gaseous products. The liberated ash at the process temperatures up to 1300 melts and flows down the sludge collecting box 5. Dry distillation products and gasification of coke passes through the openings of the grate 15 and enter the coil 4, where the high temperature cracks the tar vapors. The resulting gas then passes to the regenerative chamber 5, where it gives a portion of tagGl to the fuel in the bunker and to the air passing through the air supply and the second pipe 6. When exiting the generator, the gas branches: approximately 2/3 of it goes to the cleaning and cooling system and further to the consumer, a / s is supplied to the gas burner and burned in the combustion chamber 8. The combustion products are sequentially heated by the coil 4, the cylinders 2, the preheating chamber 5 of the secondary air, the hopper I and through the exhaust pipe 10 are discharged to the outside.

Secondary air enters through a check valve //, passes through the annular space between

shrouds and through the central channel of the box about enters the combustion chamber.

Ignition of the generator is dried by heating it with a steam lamp or otherwise through the hatch 12. The amount of gas to be transmitted to the burner is controlled by an automatic valve 14.

The use of distillate gas in engines yields a significant (20-50%,) increase in px power compared to the work on the generator gas, due to an increase in the heating value of the working mixture and an increase in the feed rate from pressurization resulting from increased gas pressure.
