ELECTRIC POWER GENERATION SYSTEM AND METHOD OF POWER GENERATION FROM COAL GAS WITH LOW CALORIFIC VALUE Russian patent published in 2020 - IPC F22B31/08 F01D15/10 

FIELD: physics.

SUBSTANCE: invention relates to a power generation system. System for power generation from coal gas with low calorific value comprises a boiler operating on coal gas and an electric generator plant. Electric generator plant includes steam turbine and electric generator. Boiler operated on coal gas comprises furnace housing and boiler drum. Furnace body contains a horizontal furnace channel and a vertical heating channel and is equipped with a water screen located on it. Water screen communicates with fluid outlet and steam outlet of boiler drum. Housing of the furnace is also equipped with a superheater unit and an economizer unit. Superheater unit communicates with the steam outlet of the boiler drum and inlet of the high-pressure cylinder of the steam turbine. Economizer unit communicates with steam turbine exhaust steam outlet and boiler fluid inlet. On furnace housing there is an overhead pipeline and shield screen pipeline, separated saturated steam is delivered to ceiling pipeline through boiler drum, steam is divided in overhead pipeline into four tracts.

EFFECT: invention is aimed at increasing efficiency of electric power generation from coal gas with low calorific value.
