Abstract

The invention discloses an ash and burnt removal agent composition for rural domestic waste incinerator. The ash and burnt removal agent comprises the components with the following weight portions of 50-70 percent of nitrates, 5-10 percent of loosening agent, 10-15 percent of sodium chloride, 5-15 percent of activator, 5-10 percent of vermiculite and 1-2 percent of cupric oxychloride. The nitrates are cupric nitrate and sodium nitrate. The loosening agent refers to borax. The activator refers to ammonium nitrate, carbon powder and sulfur powder. The ash and burnt removal agent is applied in ash and burnt removal field of the rural domestic waste incinerator, which has good effect for improving the ash and slag in the waste incinerator.

Description

technical field [0001] The invention is applied to the field of ash removal and decoking of municipal solid waste incinerators, and particularly relates to a soot remover for municipal solid waste incinerators. Background technique [0002] Ash accumulation and slagging on the heating surface of boilers are common phenomena in boiler operation, and they are also one of the important factors that endanger the safe operation of boilers. Since the thermal conductivity of the dust layer is hundreds of times lower than that of the metal pipe wall, even if the heating surface is slightly dusted, the additional thermal resistance brought by the dust layer will account for 1 / 3 of the total heat transfer resistance inside and outside the heating surface of the soda. above. Boiler ash accumulation and slagging problems may cause poor heat transfer on the heating surface, increase the exhaust gas temperature, and reduce boiler efficiency; in severe cases, the combustion conditions wil...
