YGL series coal or biomass thermal oil boiler is a new type heating equipment with the fixed grate as combustion equipment, it is a vertical type boiler with coal or biomass (wood chips, bamboo chips, straw, rice hull, peanut shell, bagasse, mustard stalk, cotton stalk, cotton seeds, coconut shell, corncob, waste cloth, etc.) as fuel, and flue gas as heat source, heat conduction oil (such as L - QB, L - QC, L - QD, etc.) as the heat carrier, through the circulating pump to force heat transfer medium to circulate in liquid phrase, and transfer heat to heat user equipment, then return to the heating furnace for reheating, it is a kind of high temperature, low pressure, energy-saving equipment. Heating temperature can be as high as 340 ℃, and generally under working pressure of 0.8 MPa. Because of working in liquid state, it is safe and reliable.





1. Strong adaptability of different fuels 

Separated design for combustion equipment and upper furnace, according to the different nature of the solid fuel, furnace can be design individually . 

2. Diversity of grate structure 

The structural grates has fixed and moving types, depending on the fuel nature, it can be manual or mechanical feeding. 

3. Large diameter combustion chamber 

The boiler combustion chamber is composed of vertical large diameter circular tube, large fuel combustion space to ensure complete combustion, achieves high thermal efficiency. 

4. Best coil design 

Furnace internal and external spiral coil is made of bulls, small diameter steel pipe coil thermal expansion of good performance, low stress, safe and reliable. 

5. Optimal process design 

Three return flue gas, medium flows through the inside and outside coils, with uniform velocity, safe and stable operation. 

6. Sufficient output 

Reasonable heating surface layout, large area, good heat transfer effect, high efficiency, stable output, sufficient. 

7. Perfect automatic control

Precision control on outlet oil temperature, multiple protection and control are set on medium temperature, pressure and smoke temperature to ensure safe and reliable operation.
