[0053] use figure 1 One embodiment of the present invention will be described. A is biomass raw material, B is coking wastewater, C is desalination circulating water, D is condensed water, E is high-pressure steam from flash tank, F is oil-water mixture, G is biomass tar, H is crude potassium salt, I is Blast furnace gas, J is combustion-supporting air, K is high-temperature waste gas, L is low-temperature waste gas, M is biomass hydrothermal charcoal, N is bituminous coal, O is anthracite, P is a mixture of biomass hydrothermal charcoal and coal, and Q is high-pressure nitrogen . The biomass A is crushed by the pulverizer 1, and the slurry is prepared in the slurry storage tank 2. The pulping water can be one or both of coking wastewater B and desalination circulating water C in an appropriate proportion. The prepared slurry is transported under pressure by the high-pressure slurry pump 3. In order to improve the hydrothermal carbonization efficiency, the slurry is preheate...
