Forced Circulation Diesel Oil Fired Thermal Oil Boiler 350kw - 7000kw Capacity

YY(Q)W Model Natural Gas LPG LNG CNG Diesel Oil Fired Thermal Oil Boiler

Introduction Of YYW thermal oil boiler

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.

Advantages thermal oil boiler designs

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.

Features of Gas/Oil fired thermal oil boiler 

1. Unique tail heating surface design,boiler rolling chamber wet back structure,small boiler heat loss,avoid overheat caused by over-burning of side panels, and increase thermal efficiency by 2-3%
2. Unique coil tube repair and integration process, the disk is compact and no gap,there is no smoke short circuit,long gas flow, heated fully, high efficiency

3. Triple coil,three-pass smoke,fire wrapped in oil structure design, large radiant heating furnace,high thermal efficiency of the boiler,prevent the boiler shell from firing deformation at the high temperature
4. Boiler multistage energy saving device design (the tail can set air preheater, wasted heat boiler,economizer),low smoke exhaust temperature, improve boiler efficiency 10%
5. Research PCL control board independently,strong compatibility,PLC intelligent touch screen equipment,10-inch touch screen,fool-type operation,safe and reliable,automatic ignition/flame-out/fire switch,high fired gas,low pressure protection,gas leakage protection
