A high-efficiency and environment-friendly coal-fired power generation device

Abstract

The invention discloses a high-efficiency and environment-friendly coal-fired power generation device, which belongs to the field of coal-fired power generation devices. The high-efficiency and environment-friendly coal-fired power generation device improves the fuel of the coal-fired power generation device and performs preliminary processing of the coal to form a chain. During the use of the chain fuel, due to its own weight, it is not easy to escape from the main body of the coal-fired power generation device under the action of the updraft of the high-temperature gas generated by the combustion in the coal-fired chamber. It is not easy to form dust pollution. On the other hand, the cavities and capillary fibers in the chain fuel can effectively promote the combustion of the coal-fired body more fully, greatly increasing the thermal energy utilization efficiency of the chain fuel, and can achieve a substantial improvement The sufficient degree of coal combustion increases the utilization efficiency of fuel calorific value in thermal power plants, and it is not easy to produce a large amount of dust and other pollutants in the process of thermal power generation, and it is not easy to cause dust pollution to the environment.

Description

technical field [0001] The invention relates to the field of coal-fired power generation devices, and more specifically relates to a high-efficiency and environment-friendly coal-fired power generation device. 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, 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, and then the steam turbine drives the generator to rotate, converting the mechanical energy into electrical energy, usually It consists of the following five systems: fuel system, combustion system, soda system, electrical system and control system. [0003] The coal is transported from the coal yard to the coal scuttl...

Problems solved by technology

[0004] Although the use of pulverized coal for fuel power generation can solve the problem of insufficient fuel combustion to a certain extent, if only the pulverized coal produced by pulverizing raw coal is used, the problem of sulfide, nitrogen and dust pollutants produced during the combustion process There is still no effective solution, especially after the raw coal is crushed into coal powder, the non-combustible substances originally mixed in the coal are also crushed into small particles, which are very easy to form dust pollutants in the process of exhaust gas emission. serious pollution to the environment
