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.
May 02, 2020· This boiler is chosen if the steam demand and steam pressure are very high as in the case of a boiler for power plants. A very modern water tube boiler designed with a steam capacity between 4,500-12,000 kg / hour, with very high pressure. Working of water tube boiler. The ignition process occurs outside the pipe.
Apr 23, 2016· The difference between fire tube boiler and water tube boiler can be done on various points. These points includes types of fluid flows within the tubes, steam generation rate, floor area required for the steam generation, transportation, efficiency, fluctuating loads, operating cost etc. the knowledge of the difference about these two boiler is very crucial.
Designed with our exclusive “EX” technology, the boiler offers superior combustion along with extended surface tubes that transfer 85% more heat than traditional tubes. Additionally, the boiler has a larger furnace and simplified design for reduced stresses within the vessel.
Firetube Boiler Advantages. Firetube, Scotch Marine boilers have been used throughout the world for over a century and have been one of the mainstays behind process steam applications and industrial heating plants. The design of the current boiler products has been in place for well over 30 years. However, both market conditions and a demand
Author: Learn Engineering We briefly discuss about Water tube boiler parts and functions. D type water tube boiler. In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt
boiler has also two main categories such a s horizontal tubular and vertical tubular fire tube boiler. Normally horizontal return fi re tube boiler is used in thermal power plant of low capacity
Nov 24, 2016· Fire Tube boiler is the simplest form of the internal furnace, vertical fire tube boiler.Fire tube boilers are a portable boiler and it requires a small floor space. The steam rating in fire tube boilers doesn’t exceed 2500 kg per hour and pressure is limited to 10 bars.
Boiler Types and Classifications. There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler."Boilers that operate higher than 15 psig are called "high-pressure" boilers.
May 22, 2015· Image Credit:www.globalspec.com Some common boiler problems are described below: Fires Cleanliness of the heat recovery surfaces after the boiler can often be judged by observing the gas pressure differential above and below. Any significant rise in this value should be attended to. Whilst good combustion conditions will minimise the risk, deposits allowed to accumulate in this area are a
