Product Description
Introduction
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. It is an 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.
Application
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. 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.

Advantage
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.Large diameter combustion chamber.
Boiler combustion chamber is composed of vertical large diameter circular tube, the coil structure with series or parallel, with large fuel combustion space, complete combustion, 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.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 .
