Description

technical field

[0001] The invention belongs to the technical field of renewable energy, and in particular relates to a biomass low-temperature carbon-gas cogeneration device, a biomass low-temperature carbon-gas cogeneration device and a biomass low-temperature carbon-gas cogeneration method. Background technique

[0002] At present, straw raw materials are mostly processed by direct combustion power generation and pyrolysis. However, the calorific value of straw raw materials is low, the moisture content is high, and the cost of large-scale raw material storage and transportation is high. Direct combustion power generation projects are subject to raw material collection costs. The small scale leads to low efficiency of direct combustion power generation projects, and the alkali metal contained in the straw will corrode the boiler with the flue gas, and it will also cause poisoning of the SCR catalyst in the flue gas treatment system, thus reducing the air pollutants in the ...
