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: 296KB The steam pressure in the boiler is regulated by the Boiler Operator. This is a pressure control which senses the steam pressure and turns the boiler on and off accordingly. This control must be operationally tested. Adjust the pressure setting on the control to a pressure less than the boiler pressure (as shown on the boiler pressure gauge).
Boiler Preparation, Start-Up and Shutdown Learning Outcome It is important to note that the boiler, and steam system, are often prepared and started before the process units in a large firing rate can be increased to bring the boiler up to operating conditions.
Boiler design is the process of designing boilers used for various purposes. The main function of a boiler is to heat water for steam generation. Steam produced can be used for a variety of purposes including space heating , sterilization, drying, humidification and power generation. The temperature or condition of steam required for these applications is different, so how to design a boiler …

Mar 08, 2019· In most cases, biomass co-firing in coal power plants takes place by mixing biomass with coal before the burners, but biomass can also be gasified and burned in separate burners, after which the gaseous fuel or steam is mixed with the boiler …
Determining firing rate is a fairly straightforward equation of input/output. Your steam making capacity is determined by how much steam that you can condense. This is detailed in "The Lost Art" available on this site. You will measure the amount of radiation (the "load") and add a pickup factor, to account for heating up the piping on startup.
Typical industrial boilers are "natural circulation" boilers and do not utilize pumps to circulate water through the tubes. These units rely on the differential density between hot and cold water to provide the circulation. As the water removes heat from the tubes, the water temperature increases and it rises to the boiler steam drum.
This wastes energy and reduces efficiency. Full modulation, however, means that the boiler keeps firing over the whole range to maximise thermal efficiencyand minimise thermal stresses. This type of control can be fitted to any size boiler, but should always be fitted to boilers rated at over 10 000 kg/h. Advantages of a modulating control system:
