Abstract

This invention relates to a high temperature high pressure used heat boiler with natural circulation and dry extinguished coke including a coal-saving device, an evaporator, a film water-cooling wall, a vapour steam superheater, a boiler level and a tail flue characterizing that a dreg-coagulating tube of the water cooling wall of the front wall is set at the inlet of the boiler for increasing its heat-absorbing volume and safety of water circulation of the wall and the film water cooling walls of a suspending structure are set at the boiler level and tail flue, a boiling coal-saving device is set under the boiler levelly and the boiling rate of which is greater than or equal to 10% and a natural circulated evaporator of a vapour-water circulation mode is set levelly on the coal saving device.

Description

technical field [0001] The invention relates to a coke dry quenching waste heat boiler, in particular to a high temperature and high pressure natural circulation dry quenching coke waste heat boiler. Background technique [0002] CDQ technology is one of the most eye-catching new energy-saving and environmental protection technologies developed rapidly by foreign ferrous metallurgical complexes and coking enterprises in the past ten years. It has good social and economic benefits, and relevant enterprises in various countries are competing to adopt it. As an important part of the CDQ device system, the CDQ waste heat boiler plays the role of connecting and connecting the various subsystems of the CDQ system, recovering the waste heat of the system, and reducing the environmental pollution caused by the CDQ operation. According to statistics, my country has more than 140 large and small coking plants and more than 500 coke ovens, of which more than 160 large and medium-sized ...
