Wood Biomass Pellet Thermal Oil Heater Boiler Oil Forced
Circulation
General introduction
High efficiency biomass thermic fluid boiler for industry here
belongs to YLW boiler series, this boiler series is designed base
on the forced circulation theory, the thermal conduction oil runs
as the medium and provides high temperature at the low pressure.
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.
Fuel available
solid fuels:
coal, charcoal, anthracite coal, coal powder, pulverized coal,
lignite coal, charcoal
wood, wood logs, wood chips, wood pellets, wood shredded, wood
residues, mixed wood, wood cuttings, wood shavings, wood strips
biomass fuels, rice husk, rice hull
bagasse, straw pellets, crop pellets, corncobs, etc.
