Introduction of WNS gas / oil fired steam boiler:

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.

Technical advantages:

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.

Boiler Economiser : Definition, Function & Types

In boilers, economizers are generally Heat Exchangers which are designed to exchange heat with the fluid, generally water. Boiler Economiser and Waste Heat Recovery Concept Boilers are generally designed to produce steam from water .

Cain Industries, Inc. - Germantown, WI | Ho

The words “safely and economically recover waste heat” also mean “no-risk return on investment” which is exactly what Cain Industries heat recovery systems represent. By installing a fuel saving economizer on a combustion source, the BTU recovered pays for all the equipment installed, usually in 12 to 18 months (or an equivalent return on investment of 75 to 100% annually).

Thermal Design of Economizer for Waste Heat Recove

A two pass water-tube boiler is used as waste heat recovery boiler (WHRB).In this boiler we install economizer for efficiency improvement. Waste heat recovery economizer uses waste flue gases for steam production which has wide range of variations in parameters. By …

Boiler Economizers and Waste Heat Recove

Two solutions exist for recovering the waste heat from boiler flue gases. Conventional economizers preheat boiler make-up or feed water. Condensing economizers recover both latent and sensible heat from the flue gas, and are able to raise boiler efficiencies to over 90%.

Economizer heat exchanger - Geur

An economizer saves boiler energy consumption An average boiler operates with an efficiency of approximately 66%, which means that 34% of the energy can be considered waste heat. An economizer, also called regenerators, is a type of heat exchanger that recovers heat from flue gasses to preheat fluids or puts it to use in another part of the production process.
