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.


BLOWDOWN CALCULATION FOR BOILER This term is the most important term in boiler operation and monitoring. The parameters of the blow down are to be maintained for particular boiler. This is due to the fact that water inside the boiler gets continuously evaporated due to steam generation. Concentration of dissolve solid, inside the drum

SZL Series Coal Fired Water Tube Boiler - Coal Fir

Otherwise, water tube boiler good heat transfer property, high combustion efficiency, heating area can be layout at different types. Zhongding SZL series coal fired water tube boiler is the horizontal type double drum longitudinal type chain grate water tube steam boiler.

BOILER CONSTRUCTION : D-type boiler construction | Mari

The economizer is a multi-pass heat exchanger located above the main generating bank at the base of the exhaust stack, so that combustion gas will give up a lot of its remaining heat to the incoming feedwater before passing out the stack (Refer to Figure 2) The incoming feedwater absorbs about 100 -200 F sensible heat from the exhaust gases. . Fins are installed on the economizer tubes to

Drum sizing estimation - Boiler and Pressure Vess

Feb 24, 2003· RE: Drum sizing estimation boilerdoc (Mechanical) 23 Feb 03 13:13 Steam drum design can not be done by rule of thumb or any tables.It depends very much of the boiler type and of course the boiler capacity.I don´t think it is very helpful to give any figures like m3/t of steam produced.

Steam quality and drum sizing - Boiler and Pressure Vess

Jun 11, 2004· RE: Steam quality and drum sizing davefitz (Mechanical) 28 May 04 14:34 For high pressure boilers, the drum length and diameter is set by the mfr in order to ensure he can fit all the required steam water seperators and chevron driers in the drum, for the design steaming capacity at design pressure.

Drum Type and Once Through Boiler Design - Bright H

For high pressure boilers, the drum length and diameter is set by the mfr in order to ensure he can fit all the required steam water seperators andI concur with davefitz here entirely. With the exception of low pressure boilers, steam-water separation is accomplished with static, mechanicalThanks to all for the info. I am simply doing some research to determine why and how boiler manufacturers determine the size of their drums. TypiAs far as I know, the standard drum diameter used by a specific vendor was set according to what standard dies they had in their foundry. The drumThanks davefitz. Just not quite the answer I was looking for. That's kind of why I'm doing this researchsince the drum can be made to any sizeCurve, You can book one thing. Boilers are manufactured in a globally competitive marketplace. So factors more than just 'this is the way we hBased on my current understanding of the boiler business, the only 2 design constraints that are required by longstanding tradition are (a) pricedDavefitz, I think your (b) above needs to be modified to read, "final payment, or until the end of the warranty period." rmw Drum Type and Once-through Boilers. The major proportion of boilers operating in the world today are drum type boilers. These boilers have certain restrictions during start-up due to the presence of a high thickness component- the drum. The once through design mainly avoids this, along with a …
