Professional Gas Oil Fired Steam Boiler used in Garment Factory for Ironing
Introduction
WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/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.
This gas boiler consists of threaded firetubes, corrugated furnace, boiler shell, insulation lay, stainless steel coat, instrument valves and an integral burner.
1. Boiler Features:
1.1 Long working life
3-pass and wet-back are designed to avoid the damage of back tube sheet from the high temperature smoke.
1.2 Compact desegn
Threaded firetube and corrugated furnace are used to increase the heating area. That allows over 30% of the energy to be absorbed in the furnace. This means a shorter boiler overall. Definitely, it can save your boiler room construction costs.
1.3 New type economizer
It is made by finned ND tubes. It is smaller but the heat exchanging area is bigger than normal. By calculation, It can save around 5% fuel.
1.4 Low emissions
Lowering emissions in the ZOZEN-WNS series of boiler involves two key factors:
(1) advanced burner solution;
(2) the proper sizing of furnace to minimize nitrogen oxides and other contaminants from forming during the combustion process.
1.5 Safety control system
We design the safety interlock system with multiple protection and alarm functions
- Protection program of automatic ignition
- Locking and protection program of operation
- Protection program of extinction
- Protection program of completion
