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.
A fire tube boiler setup directs heated gases into a number of tubes that run through a water-filled chamber. Steam is created by thermal induction which transfers the heat through the walls of the tubes. These types of boilers are ideal in operations where there is a large and constant steam demand.
Rather than being a ‘type’ of boiler - such as combi boiler, system boiler or conventional boiler - the term ‘condensing’ refers to the way it functions. There are three main types of the gas boiler - Combination (or combi), System and Regular. If you are unsure about the type of boiler you currently have, these two simple questions

May 15, 2017· Types of boilers: Boiler may be classified in following types. According to the axis of boiler. 1. Horizontal boiler: If the axis of boiler is horizontal, it is known as horizontal boiler. Example Babcock and Wilcox boiler 2. Vertical boiler: If the axis of boiler is vertical, it is known as vertical boiler.
Boiler Types According to tubing methods. Ther e are two main types of boiler Fire tube boilers and … Mar 22, 2013· Thermal efficiency is simply stated as the percentage of potential fuel energy that is converted to thermal energy leaving the boiler in the form of heated water or steam. It is thermal efficiency that the consulting-specifying engineer should be most concerned with in the equipment selection process.
The different types of boilers find their use in different applications. As the time has passed, more efficient types of boilers have replaced the old and inefficient ones. This article elaborates on different types of boilers and the boiler classification. Boilers can be broadly classified as shell tube and water tube boilers.

According to the contents in the tubes, the boilers can be … Aug 26, 2019· Thermal efficiency does not account for losses from boiler radiation and convection from shell and piping. It focuses only on the heat exchange within the boiler shell. The more heat kept within the boiler, the more heat is available for transfer to the water or steam. Exhaust gas is very hot and carries roughly 30% of the boiler’s heat with it.
Biomass Energy Systems · Shots Electric Thermal Fluid Heater · Hc-2 Thermal Fluid Heaters The purpose of boiler blowdown is to control solids in the boiler water. Blowdown protects boiler surfaces from severe scaling or corrosion problems that can result otherwise. There are two types of boiler blowdowns: ''continuous'' and ''manual''. A continuous blowdown uses a calibrated valve and a blowdown tap near the boiler water surface.
