Features & Advantages

01

High Security, 100% Safe Operation

①Anti-dry heating system with five stages water level check; ②Four stages pressure protection; ③Explosion-proof door with fire viewer; ④Remote monitoring system.

02

Double 12cm thickness aluminum silicate insulation layer

Assure the boiler surface temperatureis below 30°C, safety to boiler operator, and good work condition in boiler room, and great reduce heat loss.

03

Spirally corrugated furnace & Wet back structure

(1)Increased 10% heating area, avoid damaged by heat expansion. (2)Reduce the back tube sheet temperature and protect it from cracking.

04

Finned tube design economizer with aluminum silicate insulation

Increase 40°C to the feed water before boiler,reduce exhaust smoke temperature below 95 C,save fuel at least 6% per hour.

Protective Function

① Water level protection, flame out protection, pressure protection, exhausted smoke over temperature protection;

② Electronic proportional control burner, with automatic ignition, flameout, and high/low flame switching;

③ Steam-water separator, high steam quality with wetness below 1%

④ Dosing devices, automatic sewage discharge devices, etc.
