Problems solved by technology

[0002] The furnaces of the existing boiling pulverized coal furnaces in various thermal power plants are usually of an empty design; there is no covering object in the furnace, and the combustion process of the pulverized coal after entering the furnace is simple, and it floats up to the furnace outlet under negative pressure, and the carbon content of the pulverized coal The phenomenon of incomplete combustion is serious, and the ash has a high carbon content, which not only has a negative impact on the environment, but also the resources are not fully utilized. For my country with large coal reserves, it undoubtedly restricts the utilization of coal energy

Abstract

The invention discloses a combustion apparatus for improving the thermal efficiency of a large-scale thermal power coal-fired boiler. The combustion apparatus comprises a furnace hearth, wherein the periphery of the furnace hearth is provided with water cooling wall pipes, the combustion apparatus is further provided with a rectifying device, and the rectifying device is used for separating the furnace hearth into a first combustion chamber, a second combustion chamber and a third combustion chamber. According to the present invention, the combustion apparatus for improving the thermal efficiency of the large-scale thermal power coal-fired boiler is provided, and has characteristics of complete coal powder combustion, effective achievement of application of the low quality coal to perform thermal power production, and thermal power coal-fired boiler thermal efficiency increasing.

Description

【Technical field】 [0001] The invention relates to combustion equipment, in particular to a combustion device for improving the thermal efficiency of a large thermal power coal-fired boiler. 【Background technique】 [0002] The furnaces of the existing boiling pulverized coal furnaces in various thermal power plants are usually of an empty design; there is no covering object in the furnace, and the combustion process of the pulverized coal after entering the furnace is simple, and it floats up to the furnace outlet under negative pressure, and the carbon content of the pulverized coal The phenomenon of incomplete combustion is serious, and the ash has a high carbon content, which not only has a negative impact on the environment, but also the resources are not fully utilized. For our country with large coal reserves, it undoubtedly restricts the utilization of coal energy. 【Content of invention】 [0003] The purpose of the present invention is to overcome the deficiencies o...
