Problems solved by technology

[0002] Existing production lines in the building materials and iron and steel industries have utilized the waste heat energy of high-temperature flue gas generated in the production process of products, while the pollutant gas SO 2 , NO x No effective measures have been taken to achieve emission reduction. With the improvement of environmental quality control requirements at home and abroad, the flue gas emitted by the waste heat boiler configured in the existing production system will not meet the environmental protection index SO 2 , NOx emission reduction requirements; on the other hand, in the face of large fluctuations in high-temperature flue gas conditions, the existing waste heat boilers cannot be adjusted

Abstract

The invention discloses a temperature-adjusting type waste heat boiler. The temperature-adjusting type waste heat boiler comprises a boiler barrel, a superheater, a high-temperature evaporator, a temperature-adjusting water heater, a low-temperature evaporator, a coal economizer, a water heater, an inlet flue, a body flue, an outlet flue, a pollutant assisting-removal device and a tail flue. The temperature-adjusting type waste heat boiler has the beneficial effects that a denitration device in a transition flue and the tail pollutant assisting-removal device are adopted for the temperature-adjusting type waste heat boiler, pollutants in flue gas can be effectively lowered, ultra-low emission is achieved, meanwhile, the temperature-adjusting type waste heat boiler can adapt to a complicated flue gas work condition, and the load adjusting range is wide.

Description

Technical field: [0001] The invention relates to a temperature-regulating waste heat boiler which recovers the waste heat of large fluctuating high-temperature flue gas produced by production lines in the building materials and iron and steel industries, and generates steam through heat exchange for power generation. Background technique: [0002] Existing production lines in the building materials and iron and steel industries have utilized the waste heat energy of high-temperature flue gas generated in the production process of products, while the pollutant gas SO 2 , NO x No effective measures have been taken to achieve emission reduction. With the improvement of environmental quality control requirements at home and abroad, the flue gas emitted by the waste heat boiler configured in the existing production system will not meet the environmental protection index SO 2 , NOx emission reduction requirements; on the other hand, in the face of large fluctuations in high-tempe...
