Abstract:
     The technology of joint production of gas and steam is that the fuel is delivered to the gasification furnace through feeder to produce gas. The gasification semicoke and low temp cycle stuff in gasification furnace deliver to combustion furnace through revert device. The gasification semicoke or gasification semicoke and portion fuel born to produce heat quantity through air blast and raise its temp, then it sends to gasificaion furnace through revert device, and at the sametime, the steam heat exchanger is heated to transfer water into steam. The portion of steam and gas supply to gasification furnace as gasification agent. The said design installation has two models: inner cycle type and outer cycle type. In this invention, the suitability of fuel is wide, utility rate is high and heat value of produced gas is high.
