Abstract

The invention relates to a high-temperature solid micro-powder residual heat boiler. The boiler comprises an evaporator, a water-cooling wall, a coal economizer, a wall-type water heater, a vapor-moisture separator, a vapor-moisture connecting pipeline, a mechanical vibration feeder, a material inlet, a material outlet, an expansion device, a steel rack and a platform, wherein feed water enters the wall-type water heater, enters the coal economizer, enters the vapor-moisture separator through a water feed pipe, enters an inlet header of the evaporator and the water-cooling wall from a downcomer of the vapor-moisture separator, reaches an outlet header after heat exchange in a snake-shaped pipe heat-exchange surface, and enters the vapor-moisture separator through an ascending pipe; and the separated saturated vapor is exhausted from a vapor outlet for power generation or utilization by the vapor-moisture separator, the separated water is subjected to the circulation repeatedly, and vapor is generated in the repeated circulation. The high-temperature solid micro-powder residual heat boiler has the technical effects of uniform and stable heat exchange, can be used for reclaiming a great number of vapor, and has good economic benefit and social benefit.

Description

technical field [0001] The invention relates to a solid waste heat boiler in the metallurgical industry, in particular to a high-temperature solid micro-powder waste heat boiler. Background technique [0002] At present, the waste heat resources generated by the production of magnesia in the metallurgical industry are mainly composed of two parts, the calcination waste gas from the kiln and the sensible heat from the calcination products. The exhaust gas is introduced into the waste heat boiler to generate steam to utilize this part of the heat, but the sensible heat of the solid micro-powder from the calcined product has not been found to be recycled in a suitable way. Currently, the waste heat boiler for recovering high-temperature solid waste heat mainly has the following forms: 1. Recover high-temperature bulk Waste heat boilers with loose solid waste heat mostly use forced convection to heat the air, and then recover this part of heat through conventional waste heat boi...
