Product Advantage
  • Three-pass Structure of Coal Fired Steam Boiler

    Boiler adopts single drum horizontal three-pass structure with large furnace, which fully guarantees sufficient heating surface of boiler and sufficient steam output. And spirally corrugated tube are used to enhance heat transfer and improve thermal efficiency.

  • EPCB Boiler Chain Grate

    Adopt movable chain grate. According to different fuel characteristics of users, appropriate grate pieces are selected, such as small scale grate, reciprocating grate, etc. The grate has small gap, low coal leakage and high temperature resistance up to 1200℃.

  • Refractory Material of Coal Fired Boiler

    The furnace wall of the boiler is poured entirely by high quality high-temperature refractory bricks and refractory cement. The shell of the boiler is insulated by aluminium silicate plate, which has no smoke leakage and less heat loss.

  • Economizer of Coal Fired Boiler

    Equipped with efficient economizer and dust collector. Recover the heat of flue gas, reduce the temperature of flue gas, improve the thermal efficiency, and fully ensure that the pollutant emissions of boilers meet the requirements of the national environmental protection department.

  • Electric Control of Coal Fired Boiler

    Users can choose different electric control configuration schemes with multiple interlocking protection, such as: ordinary button-type control box, easy to operate and durable; PLC touch screen intelligent electric control, directly shows the combustion situation on the the interface.
