YLW Biomass Wood Fired Thermal Oil Heater A Safer Solution for Industry YLW Biomass waste wood fired thermal oil heaters takes waste wood and biomass pellet as fuel, the heat transfer oils is heated in the tube first, then the fluid thermal oil will flow in the closed circle pipe to the heated equipment and then return to the thermal oil heater again, in this way, the heated object can reach a high temperature (Max. 320?) with indirect heating. It is especially suitable for industies which are flames prohibited. A Higher Efficiency Bidragon biomass and wood fired thermal oil heater is high efficient compared with other heating systems. 1. Multi-passes thermal conductive structure to improve the thermal efficiency greatly 2. Horizental tubes can reduce the heat loss. 3. Thicker insulated layer to reduce heat loss by thermal radiation. 4. Intelligent control system makes biomass fired thermal oil boiler operation easier and more simple.
