Biomass combustion system and process special for ceramic roller kiln

The invention discloses a special biomass combustion system and process for a ceramic roller kiln, and relates to the technical field of energy conservation and emission reduction of the ceramic roller kiln. The emission concentration of nitric oxide in the furnace is reduced while the gasification efficiency of the biomass gasification furnace is improved; liquid pentane and biomass gas are heated by waste heat of high-temperature flue gas discharged by the ceramic roller kiln, so that the liquid pentane is gasified into gaseous pentane to be uniformly mixed with the biomass gas in the gas header pipe, the heat value of fuel gas is effectively improved, and the heat value of natural gas can be basically reached. A premixed combustion mode is adopted, after being preheated by high-temperature flue gas to reach 350 DEG C, biomass fuel gas is evenly mixed with gaseous pentane in a fuel header pipe firstly, then is fully mixed with hot air in a premixer according to a proportion, and then enters a burner. 本发明公开了
