Coal or biomass fuel thermal oil boiler is a new type of heating equipment, with coal, oil, gas, biomass 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 re heating high temperature, low pressure, energy-saving equipment. Heating temperature can be as high as 340 ℃, and generally under working pressure of 0.8MPa, because of working in liquid state, safe and reliable.

Application Scopes:

Owing to its characteristics of high heating temperature , low working pressure ,energy saving, thermal oil boiler can be widely used in a variety of industrial heating process. Instead of electricity, steam heating, and it can improve the productivity.
1. Synthetic fiber industry: polymerization, melting, spinning, extension, dry .
2. Textile printing and dyeing industry: hot finalize the design, thermosol dyeing, baking, calender, drying and hot air stenter.
3. Plastic and rubber industry: hot-press, hot-extent, extrusion, vulcanization molding, calendering, injection, mucilage mixer, conveyor dryer.
4. Paper industry: dry, corrugated paper processing, calender, glue roller.
5. Wood industry: plywood, density board, hot pressing molding, wood drying, steaming equipment.
6. Building materials industry: plasterboard drying, asphalt heating, emulsified asphalt, asphalt concrete, concrete component maintenance, drying equipment, linoleum production line. 


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 running forms, depending on your fuel nature can be manual or mechanical feeding .
3. Cubic tube combustion chamber.
Boiler combustion chamber is composed of firebrick furnace and cubic tube , with large fuel combustion space, complete combustion, high thermal efficiency.
4. Best coil design.
Radiation section adopts the square coil, the convection section coil is made by serpentine, good performance of radiation coil thermal expansion, low stress, safe and reliable.
5. The 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 measures
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.
8. Leading technology in automatic control.
Boiler controller adopts Siemens/delixi electric components, reliable in performance. Controller has three forms: normal, LCD display in both Chinese and English menu, touch screen man-machine dialogue remote control. Usually we equip with normal type
