YLW series coal/biomass fired thermic fluid heater is an safe and energy saving boiler with working characteristics of low working pressure (0.8 MPa) and high temperature (350℃). The combustion equipment is chain grate (small scale flaker is available), has the advantages of feed mechanically, strong adaptability of different fuels, low coal leakage, and convenient maintenance. 

Technical Advantages

1. Large combustion chamber and excellent coil design

1) The boiler combustion chamber is composed with chain grate and large diameter coil, sufficientcombustion and high thermal efficiency.

2) The radiation section adopts square coil, and the convection section adopts serpentine coil, the heating coil has a good thermal expansibility, low stress, safe and reliable.

2. Excellent chain grate

1) The small scale chain grate boiler could resist the temperature as high as 1200℃, long working life.

2) The chain grate has a low coal leakage because of the small gap.

3) High automatic degree, decrease labor cost.

3. Wide adaptability of various coal and biomass fuel

Combustion equipment and boiler upper part are designed separately, the boiler combustion chamber could be designed based on the characteristics of different fuels.

4. Perfect automatic control

The boiler adopts PLC full automatic intelligent control cabinet and interlock protect system, has the protect function on oil temperature, medium temperature, pressure, etc, adjust conveniently.
