Coking inhibitor for waste heat boiler

The invention relates to a coking inhibitor for a waste heat boiler, which belongs to the technical field of ash removal of smelting equipment and comprises the following components: asbestos powder, manganese dioxide, aluminum oxide and ammonium carbonate. The coking thickness of the convection bank can be controlled, the phenomenon of stripping can be avoided, the coke body increasing speed is slowed down, the bonding problem of a fluidized bed furnace waste heat boiler flue gas system is effectively solved, and the safety and environmental protection risks are reduced. 本发明涉及一种余热锅炉结焦抑制剂，属于冶炼设备清灰技术领域，本发明余热锅炉结焦抑制剂的组分包括：石棉粉、二氧化锰、三氧化二铝和碳酸铵。本发明可以控制对流管束结焦厚度并有剥落现象，减缓焦体增长速度，有效解决沸腾炉余热锅炉烟气系统粘结问题，降低安全环保风险。
