Click to getHigh efficiency gas boiler is a boiler shell type 3 passes wetback gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
TKey parts (e.g. material cutting, rolling, drilling) are performed through advanced CNC machining processes to reduce assembly stress and extend boiler life.
The front and back smoke room board is cut by CNC plasma cutting machine, which is clean and beautiful.
Fully automatic operation, with automatic regulation and protection of combustion, water level, temperature and steam pressure function.
First, the connection between the smoke pipe and the tube plate is expanded to eliminate the gap between them, and then the automatic argon arc welding is adopted to reduce the stress and extend the service life of the boiler.
Longitudinal and circular joint adopts advanced automatic submerged arc welding, good welding quality. All longitudinal and periosseous joints will undergo 100% radiographic examination.
The finned tube is made of ND steel or stainless steel to avoid low temperature corrosion.
Set up check points to ensure the sequence of expansion and welding to avoid plate hole rupture.
High quality aluminum silicate fiber and fire clay insulation, the boiler body temperature can be controlled below 45℃, control heat loss.
Adequate steam storage and heating areas enable the boiler to produce high quality steam and high thermal energy.
Adding a condenser to reuse the waste heat from the exhaust to raise the feed water temperature and lower the discharge temperature can increase the thermal efficiency to more than 98 percent and save operating costs.
