Quickly start up, achieving high temperature and pressure in short time. With multi chain protection for water level and steam pressure.
The fire from top to down, fully expanded. Flame processes long and in full combustion, each part of the flue gas go through three return for heat transfer, greatly reducing the exhaust gas temperature, save heat loss and improves thermal efficiency. The boiler has controller protection and automatic recovery of the contactor to prevent electric shock function. It also has dual anti reflux and exhaust heat protection devices, which, strengthen the safety function.
Nature circle, could undertake large temperature difference.
