Manufacturing method of high-efficiency energy-saving fire coal with reticular structure

Abstract

The invention discloses a manufacturing method of high-efficiency energy-saving fire coal with a reticular structure, belonging to the field of manufacturing methods of fire coal. According to the manufacturing method of the high-efficiency energy-saving fire coal with the reticular structure, in the preparation process of the reticular fire coal, attached branches are continuously washed by coalslurry under the action of a stirring device, the coal slurry is captured by closed compartments formed by interlacing, coal balls are gradually formed under the viscosity action of the coal slurry, and the outer side of outer protective skin is coated with the coal slurry; all the parts of an attachment net are made of combustible materials, and the ignition point of each part of the attachment net is lower than a coal combustion temperature; after a fixed frame and the attachment net are soaked in the coal slurry for a long time, the fixed frame and the attachment net are taken out of a preparation bed so as to obtain the reticular fire coal which grows naturally; and the fire coal can be fully combusted, large-particle dust is not prone to being formed, air is not prone to being polluted, the heat value of the fire coal can be kept at a high level, and the combustion efficiency of the coal is improved.

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,...

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
