Introduction of WNS gas / oil fired steam boiler:

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.

Technical advantages:

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.

Steam Boiler Questions and Answe

It is outmost important that the fuel oil heaters are by-passed when firing Gas Oil or Diesel Oil. These fuels must never be heated above their flash-point. For a steam atomized burner you have to switch over to compressed air atomizing since light fuels must not be atomized by means of steam.

Why is atomization with steam done in oil-fired boile

May 07, 2017· Steam atomization is used in oil burners to assist the mixing of oil and air to promote full combustion. With steam injection, the oil is reduced to a fine spray that mixes with air and burns easily. The result is a flame that is short and intense

Steam-Atomizing and Air-Atomizing Burne

The oil pressure needs to be enough to carry oil to the burner tip, usually from 10 to 15 psi. Burners using air as the atomizing medium are designed for three air pressure ranges: low pressure to 2 psi, medium pressure to 25 psi, and high pressure to 100 psi. Figure 4-54 shows a steam-atomizing burner of the external mixing type.

Chapter 91-Oil Burners for Heating Boilers Flashcar

Regulations require that the minimum distance between an oil-fired furnace and an indoor oil storage tanks must be: a) 7m b) 5.2m c) 0.6m d) 4.7m e) 9.8m c An atomizing air compressor is usually:

Analyze Poor Oil Gun Performance in Boilers - Bright H

Performance of oil gun in both coal and oil fired boiler affects the operating efficiency of the boiler. It has influence on availability, efficiency in the case of oil fired boiler, start-up time and maintenance. There are many types of problems that can happen in oil gun performance which can be due to the influence of one of the factors above or a combination of the above.

Boiler Fuel Oil Atomizers - Marine Engineering Study Materia

Good combustion is essential for the efficient running of the boiler. It gives the best possible heat release and minimum amount of deposits on the heating surfaces. Different types of boiler fuel oil atomizers are: Simple Pressure Jet Atomizer. Figure below shows diagrammatically the principle of the simple pressure jet boiler fuel oil atomizers.

PT 2 Boiler Combustion and Firing Methods Test

Air blows the oil through n atomizer into a fine spray and swirls the oil mist into the furnace. The fuel enters the atomizing stream at or near 90 degrees thus creating a shearing action on the fuel as it enters the atomizing steam.

Steam Boiler: Oil Fired Boil

Oil fired boiler consist of several important parts such as burner nozzles, air compressor, atomizing air system, oil piping, oil metering valve system, flame ignition and the others. As in gas fired boiler , when NOx (nitrogen oxide) control is aspect of firing system, generally there could be small NOx burner controls or staged firing.
