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.
—– epa-340/1-81-007 industrial boiler inspection guide boiler inspection checklist fire tube – a boiler design . A fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or (many) more tubes running through a sealed container of water. Pre-Inspection Checklist for Low Pressure Steam . Pre-Inspection Checklist
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low
FORBES VYNCKE’s energy plants convert biomass and industrial waste into clean energy using a varied range of fuels including biomass briquettes, saw dust, spent grain, rice husk, bagasse, wood chips, coconut shell, palm oil waste, coal and many more, with thermal efficiencies above 80 %.
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.
Fire Tube Boiler Diagram. These boilers include a water level indicator; a pressure gauge, steam stop tap security tap, & a manhole like mountings for providing security as well as simplicity of working. The Fuel burns on the grate of the firebox in the boiler and the resultant hot-flue gases are permitted to flow in the region of cross tubes.
the basic fire-tube boiler was manufactured at the factory, and the refractory, insulation, boiler fittings, controls and firing equipment were installed by others. The modern fire-tube boiler is marketed as a packaged unit, and now the majority of fire-tube boilers are packaged type fire-tube boiler.
Horizontal Return Tubular (HRT) – this is an old and very simple design which is still being manufactured. The boiler consists of a shell, a tube sheet on each end of the shell, and tubes connecting the two tube sheets. The boiler is mounted above a steel or masonry furnace.
A vertical boiler with horizontal fire-tubes is a type of small vertical boiler, used to generate steam for small machinery. It is characterised by having many narrow fire-tubes, running horizontally.. Boilers like this have been widely used on ships as either auxiliary or donkey boilers. Smaller examples, particularly the Robertson type have been used for steam wagons
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.
Nov 09, 2011· FIRE TUBE BOILERS: In a fire tube steam boiler, heat and gases of combustion pass through the tube surrounded by water. Fire tube boilers steam boilers maybe either high or low pressure boilers. The three types of fire tube steam boilers are horizontal return tubular boiler, scotch marine boiler, and vertical fire tube boiler.
