Working principle: The boiler is industrial boiler, which is based on coal, heavy oil, light oil or flammable gas as fuel, heat conducting oil as heat carrier. Using recycled liquid pumps mandatory recycling, transmitting heat energy to heat equipment, and then most remaining heat return to be reheated to improve efficiency and to save energy.

Characteristic of product: It can get higher working temperature at lower atmospheric pressure and can transport heat with liquid style. Temperature of heat carrier(300º C) is lower 70 times than saturation vapor pressure. It can heat stably and get precise temperature reconciling. Having complete operating control and security devices makes heat efficiency maintained at an optimum levels at all rank of load. Saving electricity, fuel, water and electricity, you can recover the investment in 3-6 month.
