The invention relates to a method for cooperatively producing carbon and heat through gasification power generation of a biomass fixed bed. According to the method, by utilizing middle-heat-value combustible gas, the heat requirement of a high-temperature high-pressure boiler can be met, and the integral power generation efficiency is improved; and nitrogen oxide is low in content and can meet environmental protection requirements, and denitrification is not required. The method comprises the following steps: sending biomass raw materials into a gasification device for preparing middle-heat-value biomass combustible gas, gasifying the biomass raw materials under the action of air-vapor premixed gasifying agent at 700-850 DEG C so as to produce combustible gas, wherein the heat value of the combustible gas is 1600Kcal-1800Kcal, and the temperature is 200-300 DEG C; directly introducing the combustible gas into an environment-friendly combustion cavity for combustion, introducing the combustible gas into the high-temperature high-pressure boiler for combustion to produce high-temperature high-pressure steam so as to push the steam turbine to generate power, and utilizing steam waste heat discharged from the steam turbine; and heating air by virtue of an air preheater through boiler tail gas, respectively introducing hot air into a combustion cavity and the gasification device by virtue of an air blower, and utilizing the waste heat.

The application discloses a sludge carbonization method, which includes the following steps: 1) first dehydration: use hot air to reduce the water content of sludge by 10-20%; 2) low-temperature inactivation: the sludge after the first dehydration is ‑300°C for the second dehydration and inactivation, so that the water content of the sludge after the second dehydration is less than 10%; 3) Oxygen-controlled combustion: Under the condition of oxygen control, the sludge after the second dehydration is at a temperature lower than 600°C 4) Oxygen-deficient stabilization: send the product obtained from the combustion to the anoxic link for carbonization and stabilization, lower the temperature to below 40°C, and discharge to obtain the final product. The sludge carbonization method provided by this application has a small investment and can realize "sludge burning sludge", while retaining part of the calorific value, making the sludge carbonization stable, increasing added value, turning waste into treasure, and thoroughly disposing of sludge , No pollution, use the truck to carry the sludge, improve work efficiency.
