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.
semi high pressure illusion boiler - heart-soul-linedancers.be. For semi-automatic machines, water pressure and temperature must be stable and consistent, and the pressure shouldnt be too high. Typically, coffee is brewed at a pressure of about 10 bars, and the ideal water temperature is …
important from safety of the boiler. Why to maintain furnace pressure ? Incase of very low and very high pressure the furnace may subject to explosion and implosion, which may result in Boiler Structure and pressure parts, tubes damage and furnace deformation[2,3]. 2. FURNACE EXPLOSION Furnace explosion is rare, but very severe in nature.
A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.
Author: Steam and Gas Power Systems This book has been very helpful to me, in the transition phase I'm experiencing between military marine boiler technology and terms for high pressure boilers as opposed to civilian shore based steam plants and boilers. Basic principles are the same, but terms for familiar items are different, which is the reason for buying this book.
Nov 23, 2011· (The measurement psi is used to determine pressure, and stands for pounds per square inch.) By definition, a high pressure boiler is one that operates above 15 psi, while a low pressure boiler is one that operates at 15 psi or lower. Steam heating systems run with even lower pressure, typically at less than 1 psi in all.
File Size: 1MB When dumping a boiler, there should be maximum steam pressure in the boiler to force water from the boiler. False. To correct a high water level condition in the boiler, the operator must open the bottom blowdown valve. True. Bottom blowdown valves are used when dumping the boiler.
Oct 27, 2016· A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
Jul 18, 2019· Recognize that the pressure is high if the gauge reads higher than 3 bars or 45 psi. The pressure limits and ranges are different for each boiler depending on its size and type, but generally speaking, a pressure gauge should read between 1-2 bars or 15-30 psi.
A good indicator as to whether your boiler pressure is too high is if you can see water leaking or dripping from the pressure relief valve, usually located on outside wall where the unit has been installed. In some cases, a leaking pressure relief valve can cause corrosion to build on your boiler's pipework.
Simoneau Low and High Pressure Steam Boilers. Whether you are looking for a low, standard or high pressure steam generation, our steam boilers will meet your energy requirements. Span of pressure ranges from 15 to 650 psig (and above on demand) producing up to 99,9% steam purity.
What Boiler Pressure Is “Too High”? Anything above 1.5 bar isn’t ideal. 2 bar starts to become more serious and when most boilers hit 3 bar, they’re in the red zone on the pressure gauge. So, the unit is likely to lock out and display a fault code. If this happens, I’d suggest speaking to a Gas Safe boiler engineer. Why Boiler
