YLL Chain Grate Biomass Pellet Fired Thermal Oil HeaterYLL Chain Grate Biomass Pellet Fired Thermal Oil Heater takes waste wood and biomass pellet as fuel, the heat transfer oils is heated in the tube first, then the high temperature thermal oil will flow in a closed loop pipes and return to the heaters again, then heat be transfers to other energy equipment in this process. Features of Biomass Fired Thermal Oil Heater 1. Low Working Pressure This biomass fired thermal oil heaters can work under lower pressure, and reach 300? at atmospheric pressure. 2. Accurate Control of Temperature Hot oil and Oil-based thermic fluid are used as heat carrier in the heating system, so it can achieve higher heating. Operator can control the temperature accurately to meet different industry demand. 3. Safe and Reliable Performance Cloth pipes in the furnace top of the boiler, it can protect the furnace top from burning out. 4. High thermal Efficiency The heat transfer fluid flow from the low place to the high place, it is convenient to discharge the gas, so it can improve the thermal efficiency of hot oil boiler. 5. Easy to Clear the Dust The middle ash removal can protect the furnace tube from clogging.
