Economical Coal Fired Steam Boilers and Mature Solution Coal Boiler Manufacturers

Products Feature

1. It adopts special materials such as threaded pipe and arched plate to make the operation of the boiler safer and the combustion efficiency higher.

2. The optimized furnace is used to make the fuel more adaptable.

3. Fully automatic control of fuel water supply, easy to operate.

4. All the welds are automatically welded, which can effectively improve the service life of the boiler. The plate adopts advanced pressing technology to solve the problem of plate cracking to the greatest extent.

5. Adopting advanced three-layer insulation technology, the refractory layer, the insulation layer and the sealing layer are respectively from the inside to the outside. The refractory layer is composed of refractory clay bricks, which improves the high temperature resistance, and the sealing layer adopts the overall seamless sealing. This kind of thermal insulation structure can minimize heat loss and improve the combustion efficiency of the boiler.
