The belt coal feeder is suitable for improving the boiler performance of the coal feeder in the thermal power plant within a wide range of load changes. The coal furnace pulverizing system makes the control of the superheat temperature, reheat temperature and pressure temperature more stable, makes the fuel more compatible with the required air volume, reduces the excess air and gas required, and the belt coal feeder is accurate in weighing, capable of continuous coal feeding, stable in operation, energy saving and efficient, The belt coal feeder is an advanced metering coal feeding equipment matched with the pulverizer in the coal pulverizing system of the coal-fired boiler. In addition, the cylinder sealing structure of the belt coal feeder improves the pressure resistance, thus greatly reducing the internal dust accumulation of the belt coal feeder.
The belt coal feeder is continuously and evenly conveyed to the pulverizer by the conveying and metering belt inside the coal feeder. The belt coal feeder enters the coal feeder through the coal gate through the coal storage bin. An electronic weighing device is installed below the conveying and metering belt. The belt coal feeder is mainly composed of a high-precision electric weighing sensor to generate an electrical signal proportional to the weight of coal and a speed sensor to detect the belt speed signal, The belt coal feeder is composed of sub belt scales, which are sent to the integrator at the same time, and the instantaneous flow and cumulative metering are obtained after the integration.
