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.
File Size: 1MB The primary mechanism for impurities in steam is water droplets getting carried over with the steam from the boiler. “For scrubbing steam coming out of a boiler, there are a number of separation/mechanical scrubbing strategies to achieve 99.0% to 99.95% steam …
Author: Bob Formisano A poorly maintained steam boiler system will cost more to operate in the long run and could ultimately fail altogether. Why Do Steam Boilers Fail? In a steam boiler system, the two primary causes of failure are: 1. Departure from Nucleate Boiling (DNB) is caused by deposition (scaling) causing localized overheating of heat transfer surfaces.
The residential steam boiler is still alive and well despite the fact that some HVAC professionals refer to it and the steam boiler profession as the dead man’s club. However, there are not a lot of HVAC boiler technicians or HVAC companies that specialize in steam boilers because there are not a lot of the steam boilers used for residential and light commercial applications.
The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate.
File Size: 1MB Jun 14, 2018· Heat boiler up. Avoid making steam. Skim the boiler. For directions on proper skimming, read my Beck Tips in the US Boiler Report from July 2015. Adjust your pressure control to proper settings. Cut-out should normally be 2 PSI or less. Cut-in should normally be a ½ PSI or less. Some steam boilers use controls that measure pressure in ounces.
Application of a Steam Boilers: Steam Boilers are use in all process industries, where required Steam. There are Following application of steam boilers… * Thermal Power plant * Steel Industry * Textile industry * Sugar industry * Plywood industry
Continuing to heat an empty boiler may not only damage the boiler itself, but may also build pressure in the system that could lead to an explosion. For this reason, many steam boilers have a low water cut-off valve that senses when water levels are dangerously low and turns off the burner beneath the boiler.
Steam boilers consume ~0.4 HU/t for each boiler block when running at full temperature. There is then a 1.25% effeciency bonus per boiler block subtracted from this. So a full sized (36 block) furnace would use only 55% of the fuel. Whether or not the steam is being pumped out of the boiler does not …
Steam boilers are a type of boiler that has been in use for hundreds of years around the world. The average cost for a steam boiler is about $4,000.A higher end steam boiler installation could cost up to $7500. Steam boilers rely on simple mechanics, which make them so reliable to work with.Still, they aren’t particularly efficient or quiet compared to hot water boilers on the market today.
Feb 19, 2009· we should have transformer on or around the boiler putting out 24 v ac. That 24 should go up to the thermostat, back down from thermostat, through low water cutoff switch, pilot safety switch to a temp control on the boiler, to the gas valve and back to the transformer on common.
