Problems solved by technology
The present invention relates to a stereo flexible sealing method for electric power plant boiler. Said invention includes wall-passing pipe, water cooling wall, and drum and sealing layer. It is characterized by that on the described wall-passing pipe and wall cooling wall the steel nails are welded, the described sealing layer is made up by using ceramic fiber cotton and steel net, making them be successively mounted on the steel nails, making them be mutually adhered together, and then laying fire-resistant poured material on the steel net. The described steel net and steel nails are welded together firmly, so that the sealing layer can be formed into a stereoscopic sealing whole body in the boiler leakage position. The material adopted by said invention is a flexible material, so that said invention can effectively solve the air leakage and ash leakage problem of boiler.
