Abstract:In the production of waste heat boilers for oxygen rich bottom blowing furnaces in our factory, there are problems such as pipe bursts, water leakage, and frequent blockage of convection tube bundles, which seriously restrict production continuity. Conduct research and improvement on the issue of boiler water leakage from two aspects: high-temperature corrosion and smoke erosion; Optimize and solve the problem of boiler blockage from aspects such as process index control and equipment upgrade. After the implementation of the measures, the waste heat boiler achieved safe and stable operation.
