Thermal power plants play a pivotal role in the national energy supply system. As a core fuel supply procedure in power generation, coal feeding directly determines boiler combustion efficiency and overall power output.
Driven by continuous technological upgrades, advanced equipment has been widely deployed to streamline production and elevate operational & management efficiency.
Recently, Guonuo Technology’s belt weigh feeder was officially put into service at a large-scale thermal power plant, resolving long-standing drawbacks of traditional coal feeding and delivering remarkable operational benefits.
Conventional coal feeding relying on manual work or rudimentary mechanical equipment is plagued with multiple inherent flaws:
● Coal blockage: Uneven coal quality and excessive moisture frequently cause material jams, disrupting coal supply and normal boiler operation.
● Low feeding efficiency: Manual feeding and vibratory feeding fail to match high-load production and the boiler’s rapid fuel supply demands.
● Delayed coal supply: Restricted control technology makes it hard to judge feeding timing accurately, resulting in untimely coal input and unstable boiler combustion.
● Poor feeding precision: Absence of precise metering and regulation makes accurate coal dosage adjustment impossible.
Guonuo’s belt weigh feeder boasts prominent superiorities for thermal power coal feeding:
1. Strong environmental adaptability: Optimized structural design enables stable operation across varied coal types, particle sizes and complex working conditions.
2. Smooth material conveyance: Refined feeding and conveying structures effectively eliminate coal blockage. Customized against coal characteristics and feeding techniques, the feeder works reliably even for poorly flowable raw coal.
3. Anti-material accumulation: Designed on the first-in-first-out discharging principle and equipped with anti-accumulation modules, the unit monitors coal stock in real time and automatically adjusts feeding speed to prevent equipment breakdown and safety hazards caused by piled coal.
4. Uniform and steady feeding: Sophisticated control system achieves precise speed regulation to sustain consistent coal input and continuous boiler fuel supply.
5. High metering accuracy: Built-in high-precision load cells track real-time feed rate to guarantee accurate coal dosing, optimizing boiler combustion and power generation efficiency.
The successful on-site operation marks a key milestone toward automatic and intelligent coal feeding for thermal power enterprises. Featuring strong adaptability, jam-free conveyance, anti-blocking design, stable feeding and high measurement accuracy, Guonuo’s belt weigh feeder thoroughly overcomes traditional feeding defects and improves the overall operational efficiency and reliability of thermal power plants.
