PLANT FOR COMBINED PRODUCTION OF HYDROGEN-CONTAINING GAS, AND ELECTRIC AND HEAT ENERGY Russian patent published in 2011 - IPC C10J3/20 F01K11/00 

FIELD: power industry.

SUBSTANCE: plant includes gas generator 3 equipped with inputs for solid fuel and oxidiser and gas outlet, two HRSGs 4 and 6, each of which is equipped with gas and steam-water paths, gas purifying unit 5 equipped with branch pipe of sulphur-containing product, steam turbine plant 9 at the outlet of which condenser 11 is installed, condenser heater 7 with gas and water paths. Gas generator is also equipped with steam supply line from steam turbine plant 9 and slag removal line. Outlet of steam-water path 4 of the first HRSG is connected to input of steam turbine plant 9. The second HRSG 6 contains additional water outlet connected to inlet of steam-water path of the first HRSG through booster pump 15. Outlet of condenser 11 is connected to inlet of water path of condensate heater 7 through condensate pump 12, and outlet of water path of condensate heater 7 is connected to inlet of steam-water path of the second HRSG 6. Outlet of gas path of condensate heater 7 is connected to outlet of hydrogen-containing gas through compressor 8. Steam turbine plant is equipped with heat energy removal circuit.

EFFECT: increasing efficiency of plant at reduction of prime cost of produced products.
