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.
1. Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
4. Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
There are two main methods to tank heating; direct and indirect tank heating. Direct tank heating consists of placing the heater in direct contact with the heated medium by placing the heater directly in the tank or circulating the fluid directly through the heater. Indirect tank heating uses a heat transfer medium to apply the heat to the tank.
Jun 08, 2009· This is a separate insulated water tank that is heated using hot water from the gas- or oil-fired boiler. The indirect tank is usually plumbed to be a separate "zone" on the heating system. One advantage of this option is that during the warmer months the boiler only has to fire up occasionally to heat water in the indirect tank.

APPLICABILITY. 40 CFR 63.7480 to 63.7495. The boiler and process heater MACT for major sources standard establishes emissions limitations and work practice standards governing HAP emissions from the following units located at major sources of HAPs, provided the units fall into one of the subcategories listed under Types of Boilers and Process Heaters in this section:
Insulated drum heating jackets are ideal for reducing the heat loss once a drum has been heated and for providing drum insulation to ensure frost protection. Insulated drum heating jackets can be used in conjunction with drum base heaters to provide a complete heated and insulation solution.

Cited by: 12 Nickel Plating Heaters. Auto-catalytic nickel plating is referred to as Electroless Nickel plating (EN plating) using a heated solution. Best to heat the tank quickly, in about in 2-3 hours. We offer electrically heated designs for polypro tanks, stainless steel tanks and double boiler tanks.
Boilers are pressure vessels designed to heat water or produce steam, which can then be used to provide space heating and/or service water heating to a building. In most commercial building heating applications, the heating source in the boiler is a natural gas fired burner. Oil fired burners and electric resistance heaters can be used as well.
