Embodiment Construction

[0007] A coal pulverizer is installed in front of the pulverized coal boiler. After the gangue is pulverized by the coal pulverizer, the surface area increases, and it is easy to fully burn under the condition of sufficient oxygen, so as to realize the utilization of waste and squeeze it out without wasting resources. It is also in line with environmental protection. requirements.

Abstract

The invention discloses a gangue utilization technology of a pulverized coal combustion-supporting boiler, which is characterized in that a coal pulverizer is arranged in the front of a pulverized coal fired boiler; the superficial area of the gangue is increased after the gangue is pulverized by the coal pulverizer and the gangue can fully combust easily under the condition with enough oxygen; common coal gangue does not easily combust, causes much ash content after combusting and slags easily. According to the invention, wastes are utilized, consumed and squeezed without resource waste. The gangue utilization technology has the advantages of according with the environmental-friendly requirement, utilizing idle resources effectively, protecting the environment, saving the energy source, reducing the production cost and improving the economic benefits of enterprises.

Description

technical field [0001] The invention relates to a gangue utilization technology, in particular to a gangue utilization technology for a pulverized coal combustion-supporting boiler. Background technique [0002] Gangue is a thin rock layer between rocks and coal seams extracted from underground or open-pit mines or mixed into ore during the mining process. The existence of gangue is an important reason for the increase of ash content in coal. Gangue is one of the industrial solid wastes with the largest discharge in my country at present. Coal gangue has been piled up for a long time, occupying a large amount of land, and polluting the air and groundwater at the same time. Coal gangue is an available resource, and its comprehensive utilization is an important part of the comprehensive utilization of resources. Now only a small amount of coal gangue is used to generate electricity and as raw materials for building materials. Most of the coal gangue is still stored for a lon...
