[0002] Thermal power generation is a power generation method that uses the heat energy generated by the combustion of combustibles to convert it into electrical energy through a power generation device. Thermal power generation is divided into pure power supply and both power generation and heat supply according to its function. It is divided into steam turbine power generation, gas turbine power generation, and diesel engine power generation according to the prime mover. According to the fuel used, there are mainly coal-fired power generation, oil-fired power generation, and gas-fired power generation. In order to improve the overall economic benefits, thermal power generation should be carried out as close to the fuel base as possible. There are three types of energy conversion processes in thermal power generation. Thermal power plants use coal as a primary energy source and need to transfer and transport coal into the boiler. Transfer and transportation are required, but at present, short-distance belt conveyors are generally used for coal transfer and loading. During operation, the coal is easy to deviate and difficult to adjust, and the belt is also easy to be scratched and torn, posing a safety hazard. In addition, when the belt conveyor is running, coal dust flies, which can easily cause poor environmental sanitation. Therefore, a new type of vibrating feeder suitable for coal transfer is needed.
