Electronic Belt Scale Coal Feeder
Series DPG electronic belt scale coal feeder manufactured by Beijing Power Equipment Group is the gravimetric coal feeder with the characteristics of good pressure resistance, energy saving and environment friendly designed, and has already become the series product of mature technology, reliable operation and stable performance.
The coal feeder is suitable for the coal-fired furnace pulverizing system of a thermal power plant, which can improve the performance of the boiler under a wide range of load fluctuations, and make the control of the superheating temperature, reheating temperature and pressure temperature more stable, and the fuel and the required air. The quantity is more matched, the required excess air is reduced, the coal is continuously fed, the weighing is accurate, the work is stable, the energy saving is high, and it is the advanced metering coal feeding equipment matched with the coal pulverizing machine in the coal-fired boiler pulverizing system.
The product is totally sealed and has no environmental pollution. It can provide continuous, stable and accurate coal for various types of coal mills. It can operate normally under negative pressure, normal pressure and positive pressure. It can be operated locally or remote-controlled, and it can automatically adjust the quantity of coal after it is connected with the main control room. The product is tested in the factory before leaving the factory, and the running parameters are adjusted to ensure the quality of the product.
● Product Model and Performance Parameter
Rated Coal Feeding Amount 1.5-200t/h
It is fully enclosed pressure resistance gravimetric coal feeder with the measuring accuracy as ±0.5％ and the control accuracy as ±1％.
●Scope of Application
It can meet the requirements of the pulverizing system in the industries such as power, metallurgy, building materials, coal, chemical, etc.. It can match with the coal mill or circulating fluidized bed unit in the power plant.
When the material is conveyed by the metering tape, the weighing device will detect the weight of the material on the belt conveyor, act on the load cell, generate a voltage signal proportional to the belt load and feed it to the totalizer. At the same time, the totalizer receives the speed signal transmitted by the speed sensor, and obtains the instantaneous flow value and the accumulated weight value through amplification, shaping, A/D conversion processing and integral calculation.
The temperature sensor inside the feeder detects the temperature and compares it with the set value. When the critical point is reached, it outputs a signal to the control system. The quick shut-off device executes the command, immediately shuts off the valve, cuts off the flow, and blocks. The purpose of hot air reflow.
