Sludge gasification coupled with coal-fired power generation system
The SG-sludge drying and gasification coupling coal-fired power generation system technology adopts the process of steam indirect drying and fluidized bed gasification. The sludge in this process does not directly enter the boiler for combustion, which prevents the diffusion of heavy metals and has almost no impact on the boiler. The fully enclosed drying system is adopted, and there is no odor release in the whole process. The ash after sludge gasification can be used as a building material. This process realizes the recycling, harmlessness, reduction and stabilization of sludge, and has very high economic and social benefits.
