A heat-resistant flue for biomass energy hot blast stove, including elbow, explosion-proof port, cleaning door, heat-resistant stainless steel anchor, refractory pouring material. The flue is made of metal frame, pouring refractory pouring material, introducing special heat-resistant stainless steel as anchor, and adding thermal expansion difference of asphalt coating on anchor. A connecting flange is arranged at both ends of the flue, which is convenient for installation, and the upper part is provided with a sling. The flue elbow is installed at the top of the combustion chamber, which is the inlet of flue gas into the flue. The flue is connected with the elbow of the flue, and the other end is connected with the flue of the cleaning door, and the explosion proof device is connected with the explosion-proof device at the top. One end of the cleaning door flue is connected with the entrance of the heat exchanger, and the other end is connected with the flue port of the explosion proof mouth. High temperature stainless steel anchor is welded inside the metal plate of the flue, and the high temperature resistant material is asphalt and refractory pouring material. The utility model has the advantages of reasonable structure design, favorable smoke flow and certain shape, which is time-saving, durable, heat resistant and can be prefabricated in batches.
