Problems solved by technology

[0004] Existing coal combustion collectively produces residues during the combustion process, resulting in incomplete combustion of coal, easy to generate large particles of dust, and seriously pollutes the air. At the same time, it will reduce the calorific value of coal combustion and reduce the combustion efficiency of coal. Affect the production efficiency and economic benefits of thermal power plants

Embodiment 1

[0039] see figure 1 , a high-efficiency energy-saving coal-fired manufacturing method with a network structure, the main steps of which include:

[0040]S1, primary selection, primary selection of candidate coal, removal of large particle impurities mixed in coal, to facilitate follow-up work;

[0041] S2, crushing and removing slag, sending the primary selected coal to a pulverizer for crushing, and sieving the crushed coal to remove large-diameter and high-strength impurities to obtain powdered coal;

[0042] S3, flotation pulping, the powdered coal that has been crushed and slag removed is subjected to flotation, and the purity of coal is further improved by flotation, and at the same time, desulfurization and denitrification of coal are carried out by adjusting the flotation liquid, especially, coal flotation desulfurization and denitrification It is a well-known technology for those skilled in the art, and those skilled in the art can reasonably select flotation equipmen...

Abstract

The invention discloses a production method of high-efficiency and energy-saving coal-fired with a network structure, which belongs to the field of production methods of coal-fired. In the process, the coal slurry continuously scours the attached branches and growth fiber clusters under the action of the stirring device, and the airtight compartment formed by the interweaving of the growth fiber clusters is used to capture the coal slurry, and gradually forms coal balls under the action of the viscosity of the coal slurry itself. The slurry will also be coated on the outside of the outer protective skin, and all parts of the attachment net are made of combustible materials whose ignition point is lower than the coal combustion temperature. After soaking the fixed frame and attachment net in the coal slurry for a long enough time, Taken out from the preparation bed, the naturally grown mesh-shaped coal can be fully burned, and it is not easy to form large particles of dust, and it is not easy to pollute the air. At the same time, the calorific value of the coal can be kept at a high level. level, increasing the combustion efficiency of coal.

Description

technical field [0001] The invention relates to the field of coal-fired production methods, and more specifically, relates to a high-efficiency, energy-saving coal-fired production method with a network structure. Background technique [0002] A thermal power plant, referred to as a thermal power plant, is a factory that uses combustibles (such as coal) as fuel to produce electrical energy. Its basic production process is: when the fuel is burned, the water is heated to generate steam, and the chemical energy of the fuel is converted into thermal energy. The steam pressure drives the steam turbine to rotate, and the thermal energy is converted into mechanical energy. Then the steam turbine drives the generator to rotate, and the mechanical energy is converted into electrical energy. A thermal power plant is a large and complex factory that produces electricity and heat. It consists of the following five systems: fuel system, combustion system, soda system, electrical system,...
