OPERATING METHOD OF GAS GENERATOR PLANT AND GAS GENERATOR PLANT Russian patent published in 2020 - IPC F02B43/08 

FIELD: power engineering.

SUBSTANCE: group of inventions relates to power engineering and can be used in households, farms and industry for burning garbage and wood wastes. Objectives of creating a group of inventions is to accelerate combustion of raw material of high humidity while providing maximum allowable concentration of hazardous substances in exhaust gases. Solving said problem is achieved in a method of operating a gas generator plant, comprising loading source material and feeding air into the main cavity of the gas generator, ignition of initial material and supply of gas-generator gas through gas line to internal combustion engine, to which electric generator is connected for electric power generation, exhaust of exhaust gases from exhaust system of exhaust gases of internal combustion engine after its preliminary cleaning in catalytic afterburner, at that after loading of initial raw material into main cavity of gas generator and before supply of air into gas generator upon command from control unit gas generator is switched into "mode of initial material drying", for this purpose exhaust gases are supplied from exhaust system of exhaust gases in internal combustion engine operating on liquid fuel, and after ignition of initial raw material gas generator is changed into "main mode", for this purpose internal combustion engine is switched to operation from gas-generator gas, periodically crumbs vault of starting material agitator, comprising working member installed in main cavity, and reciprocating drive with connecting rod, in that in "main mode" continuously by means of wattmeter output power of electric generator is measured and by means of flow meter is air flow to gas generator and this information is transmitted to control unit, which increases air flow to the gas generator until the output power increases, and when the maximum power value is reached, increasing the air flow rate, and when power is reduced – air flow is reduced, when power is lower than maximum allowable value, air supply to gas generator is disconnected, internal combustion engine is switched off, gas-generator gas is discharged inside main gas generator cavity through discharge pipeline for combustion into atmosphere, wherein ionized air is added thereto, ash is unloaded and initial material is loaded again. At "main mode" gas generator gas activation and ozonation of air supplied to gas generator are performed. After the gas generator plant exits into the "main mode", emission of harmful substances from the exhaust system is constantly monitored and when the concentration of maximum permissible standards is exceeded, the degree of ozonation of air supplied to the gas generator is gradually increased, and, if this does not result in the desired result, the air flow rate is increased or decreased to achieve the concentration of emission of hazardous substances of maximum permissible values regardless of the maximum output power of the electric generator and the work is continued in "steady-state" mode. After operation of gas generator plant in "steady-state mode" ozonation of air at inlet of internal combustion engine is switched on. After operation of gas generator plant into "steady-state" mode, ozonation of air at inlet of catalytic afterburner is switched on. Also disclosed is gas generator plant.

EFFECT: providing maximum permissible concentration of hazardous substances in exhaust gases at all modes.
