Wood chip fuel thermal fluid heater boiler is a new type of heating equipment, with solid fuel (wood chip, biomass pellet, rice husk, 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 re-heating high temperature, low pressure, energy-saving equipment. Heating temperature can be as high as 340 ℃, and generally under working pressure of 1.1MPa, because of working in liquid state, safe and reliable.

Main Features
1. Unique seal for the smoke box
With the overall structure for the lid, the multi-stage labyninth seal, unique sealing process and material, good compressibility, complete reduce its flue gas leakage, which can be reused. 
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. Multi-function safety and explosion-proof device
The furnace rear is equipped with explosion-proof device, which is connected with the boiler furnace. Once the fuel is bleed and exploded in the furnace, discharging high energy at the moment, it will automatically reset. While it has the function of the endoscopic view of fire and maintenance channel. Using the combustion adjustment in operation, it is easy for furnace inspection and maintenance. 
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. 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.
6. 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 .

Owing to its characteristics of high heating temperature , low working pressure ,energy saving, Our wood chip fuel thermal fluid heater boiler can be widely used in a variety of industrial heating process. Instead of electricity, steam heating, and it can improve the productivity.
1. Petroleum chemical industry: polymerization, melting, condensation, distillation,forced heat preservation.
2. Oleo chemical industry: fatty acid distillation ,fat splitting, distillation, concentration, esterification, vacuum deodorization.
3. Synthetic fiber industry: polymerization, melting, spinning, extension, dry .
4. Textile printing and dyeing industry: hot finalize the design, thermosol dyeing, baking, calender, drying and hot air center.
5. Plastic and rubber industry: hot-press, hot-extent, extrusion, vulcanization molding, calendering, injection, mucilage mixer, conveyor dryer.
