Vertical Low Pressure Chain Grate Biomass Fired Thermal Oil Boiler
Vertical Low Pressure Chain Grate Biomass Fired Thermal Oil Boiler
I. Features of the thermal oil boiler:
1. The position between the burner joint and the coil is sealed with good seal, large flexible space, to increase the service life of burner and enhance the heating efficiency.
2. Triple coil structure is adopted by the boiler with three-pass flue gas, compact design and space-saving. Heating efficiency of the air pre-heater enhance up to 92% or more.
3. Multiple running with safety protection make boiler’s operation more safety and simply. High temperature control precision (± l°C) and good combustion effect.
4. Automatic control functions, to extend the service life of equipment while saving human resources.
