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.
ISO 9001, CE, BV, SGS, ASME
Different coal and biomass fuels
1. Separated design for combustion equipment and upper furnace, according to the different nature of the solid fuel, furnace can be design individually .
2. The boiler combustion chamber is composed of vertical large diameter circular tube, large fuel combustion space to ensure complete combustion, achieves high thermal efficiency.
3. 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.
4. Three return flue gas, medium flows through the inside and outside coils, with uniform velocity, safe and stable operation.
5. 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.
The structural grates has fixed and moving types, depend on the fuel nature, it can be manual or mechanical feeding.
We adopt Siemens PLC and Schneider electrical components. can realize automatic interlock control to ensure boiler safe operate.
Air preheater could be equipped to extract the heat form the flue gas, make fuel use of heat, increase thermal efficiency.
We adopts the stainless vertical pump with low noise, stainless impeller and pump body.
Standard configuration: one inlet, three outlets, equipped with pressure gauge and thermometer. It can be designed according to customers' requirement.
It is fully automatic and free debugging. We adopts PE material for salt tank body, it has hard texture and it is easy to move, anti-shock, and no leakage.
Zhongding Boiler pay more attention to the boiler quality from raw material to producing process.
