Asphalt Mixing Plant Used Thermal Oil Heater Boiler For Heating Bitumen
General Introduction
YY (Q) W series thermal oil boiler is a kind of boiler which uses gas(oil) as fuel ,thermic oil as medium, hot oil circulation pump to make the medium to forced circulation, deliver the heat to heating need equipments and then go back to the heating furnace.It can obtain a high operating temperature at low pressure and
can do high-precision control on the medium.
This series boiler has compact structure. The heating area is constituted by close-knit coil pipes from inside to outside.Inside coil pipes are the radiation heating surface, and the outer surface of inside coil pipes and outside coil pipes form a convection heating surface.Fuel burn fully in the combustion chamber, the radiation heating surface absorb most heat, and then high temperature flue gas goes into convection heating surface to exchange heat, then go into the air preheater (or waste heat boiler) to heat the required (or water).at last, the low temperature flue gas discharges to the aerosphere through the chimney.

Thermal oil heater advantages
1.It is easy and convenient to install the boiler,only setting the boiler on the foundation.
2.Heating surface is formed by round coilers,sufficient arrangement,reducing thermal load of tubes surface to ensure safety.
3.Furnace dimensions is matching with the combustion flame,positive pressure combustion,high radiation heat exchange efficiency.
4.Boiler structure is compact,saving the floor area of boiler room.
5.An air pre-heater or heat recovery boiler is placed behind the boiler to improve the thermal efficiency.
