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: 296KB Boiler type. Most old gas and oil boilers are regular boilers that have a separate hot water cylinder to store hot water, rather than providing it directly from the boiler. When you replace your boiler you can buy a new regular boiler, and keep your hot water cylinder, or buy a combi boiler that doesn't need a cylinder.
The System. The Oil Boiler Re-imagined. The engineers at Energy Kinetics have deconstructed every component of the conventional cast iron boiler and used superior design and materials to recreate it as not only the world’s most energy efficient oil boiler, but also as …
Upgrading your furnace or boiler from 56% to 90% efficiency in an average cold-climate house will save 1.5 tons of carbon dioxide emissions each year if you heat with gas, or 2.5 tons if you heat with oil. If your furnace or boiler is old, worn out, inefficient, or significantly oversized, the simplest solution is to replace it with a modern
Shifting to real time efficiency monitoring can improve the boiler efficiency significantly depending upon the boiler type and actual conditions at site. In nutshell, monitoring and maintaining the boiler efficiency for the overall operational life of the boiler is a must to cut fuel bills and reduce carbon footprint.
Trapping this heat, the boiler gains 10% more of efficiency, rating up to 95%. These technical characteristics make gas boilers much more beneficial than oil ones. Having a high efficiency natural gas boiler helps to save more, while paying the bills. Look for a model to suit your heating system and take all the benefits provided!
Gas boilers cost $5,228 on average, with a typical range of $2,728 and $7,735.Price depends mostly on efficiency and output as well as brand. You'll pay about $2,000 to $3,000 for a unit with 50,000 to 100,000 BTUs and an AFUE of 82 to 85 percent. Appliances with …
What is combustion efficiency in steam boiler?Managing your boiler with the best amount of excess air will reduce heat loss up to the mass and enhance combustion efficiency. Combustion efficienWhat are the factors of combustion efficiency?The thermal efficiency and combustion efficiency of a condensing device will be different. The only way to determine the exact thermal efficiencyWhat are direct and indirect efficiencies in boiler?The overall boiler efficiency relies on many parameters apart from combustion and thermal conductivity. These other parameters include ON-OFF damag An efficient natural gas burner requires only 2% to 3% excess oxygen, or 10% to 15% excess air in the flue gas, to burn fuel without forming excessive carbon monoxide. Most gas burners exhibit turndown ratios of 10:1 or 12:1 with little or no loss in combustion efficiency. Some burners offer turndowns of 20:1 on oil and up to 35:1 on gas. A higher
Lennox GWM-IE Boiler. Earning the Energy Star Most Efficient 2015 Label, the Lennox GWM-IE is … But once you know which type and size you need you can use the boilers' energy efficiency ratings to refine your choice of boiler and pick the most efficient one. ErP energy rating All modern boilers are rated for efficiency under the new European energy label introduced in September 2015.
