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: 379KB Packaged boiler is the most common and efficient type of fire tube boiler used in industry to produce steam and hot water. This boiler delivers to site as a whole package factory assembled. The package boiler only requires electricity, water, steam and fuel connections and it is ready to produce steam.
Jun 04, 2020· 12) Low atomizing steam pressure : where steam is used as the atomizing medium this trip will occurs if any obstruction is in the hole of the steam supply, or the pipeline supplying the steam. 13) Flame Failure : [NOTE: This is Overridden during starting up/firing up of the boiler] This trip occurs to prevent the accumulation of fuel into the
combustion problems, the boiler must have an adequate supply of fresh air and a supply system that does not affect the boilers operation. HOW MUCH AIR IS REQUIRED? In general, the following formulas have been developed to determine the amount of air required for any boiler room with a package firetube boiler firing gas or oil fuels. 1

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
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
Introduction Fire Tube Steam Boilers are the most traditional technique for the production of saturated steam, high pressure hot water or superheated steam for a range of outputs from 250 to 50 000 kg/h (175 to 34 000 kW). Operating Principle Steam is generated by heating a large volume of water in a pressurised drum by means of hot gases, which are produced from the combustion of liquid or

Operation · Types of fire-tube boiler · Variations · Safety considerations · Economics and efficiencies A cast iron boiler is one in which combustion gases rise through a vertical heat exchanger and out through an exhaust duct. Water in the heat exchanger tubes is heated as it moves upward through the tubes. Cast iron boilers produce low pressure steam or hot water, and generally burn oil or natural gas.
Author: Noria Corporation Heat loss from the boiler jacket could range from 1/2% to 4% of the boiler output, depending upon operating pressure or temperature, boiler size, type of construction, and insulation thickness. Typically, the larger the boiler the lower the loss as a percentage of boiler output.
File Size: 113KB As the process steam demand increases, the steam pressure at the boiler deceases. The boiler steam-production controller will measure this decrease in pressure and will increase fuel flow to the boiler. In the case of a natural-gas-fired boiler, the controller will proportionally open the fuel control valve. As the fuel flow is increased, the
