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.
Author: Ray Wohlfarth Where an external expansion vessel is fitted, and the cold boiler pressure is 1 bar, you may see a rapid rise in boiler pressure as the system heats up. This is because, with a pre-charge pressure of 1½ bar, the expansion pocket in the external vessel is only available once the boiler pressure reaches 1½ bar.
Eric's graph indicates "gauge pressure". When you use the steam tables, you have to add "atmospheric pressure" (Patm) to "gauge pressure" (Pg) to get "absolute pressure" or P. Adding 1 bar at sea level is about right. 1 bar = 0.987 atmosphere = 29.53 inches of mercury
Sep 28, 2016· 4 things to look out for in steam boiler pressure controls People get confused about the proper setting of a steam boiler pressure control, especially on a boiler with a multiposition burner. Typically, the steam pressure inside a commercial boiler is controlled by two main pressure controls; one is the operating control and the other is
Sep 14, 2017· Close the filling valves when the pressure gauge hits 1 bar. As cold water enters the boiler, the arm on the pressure gauge should begin to move up from 0. When it moves to 1 bar, turn the valves clockwise into the off position. This will turn off the flow of water. After 30 seconds, the pressure in the boiler should stabilize.
User rating: 3.7/5 Only part of the benefit of a boiler or water heater upgrade can be realised unless a review and improvement to the control system is implemented. For multiple boiler installations a good boiler sequencer, such as Hamworthy's Merley controller, will help maximise the benefits of the new boiler plant and since older atmospheric boilers only
The position set when the boiler was installed is sometimes shown by a red indicator needle. On most digital gauges, you’ll see a flashing pressure reading, if there’s a low (or high) pressure warning. If your boiler pressure reads less than 1 bar, it’s possible that you might have lost water from the system, which needs to be replaced.
User rating: 70/100 Boiler Types and Classifications. There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler."Boilers that operate higher than 15 psig are called "high-pressure" boilers.

Automatic Water Feeder Valves · Aquastats · Steam Boiler Pressure The pressure gauge needle indicates the actual pressure of the system. A green zone shows the correct pressure range, while a red zone shows the critical zone.: A red needle serves as a marker, while a black needle corresponds to the actual pressure.These two needles should be on top of one other.: In some boiler models, the water pressure is given by indicator lights on the control panel.
File Size: 1MB One of the most misunderstood components inside a boiler room is the barometric damper, which is used to control the draft inside a boiler. It is installed on boilers that use a Category I vent. To understand how the barometric damper operates, we need to understand what draft is. We all know when air is heated, it will rise. When hot air from the boiler rises up the stack, it must be replaced
