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.
Based on pressure steam boiler can be classified as high pressure steam boiler and low pressure steam boiler. A high pressure steam boiler is boiler in which steam is generated at pressure exceeding 15 psig and operates hot water boiler above 160 psig or 250o F. Application this type usually is used for utility plants, big industrial plants and
Nov 01, 2016· If we are speaking of home steam heating boilers the pressure is controlled by a device known as a Pressuretrol which can be adjusted for cutout or cut in pressure and differential normally. If your pressure seems to stay too high,, keeping the bo
Apr 28, 2018· This question will be a puzzle in a tropical country where boilers stand for part of a thermal power or processing plant. Even in waste heat recovery, low pressures are not preferred due to pressure losses incurred while handling the voluminous st
How do I know if my boiler pressure is too low?Most UK households use a gas combi boiler for heating and hot water, with a pressure gauge that can usually be located on the control panel. It isWhat are the risks of low boiler pressure?The good news is that low boiler pressure is nothing to panic about and is not likely to cause any damage to your boiler. On the other hand, it cWhy is my gas boiler pressure too low?The most common reason for your gas boiler pressure being too low is either a water leak somewhere in the system or reduced system pressure as a reHow to find a water leakIt is not always easy to find a water leak in your system as there will often be pipework that is not visible. However, it if you are experiencingHow can I fix low boiler pressure?The most effective way to fix a problem with low boiler pressure is to repressurise the system. This can usually be done yourself without the need If the pressure is below 1 bar, then your boiler is likely to have low pressure. What to do if your boiler has low pressure. Once you know that the drop in pressure hasn’t been caused by a leak, or a leak has been fixed, you can re-pressurise your boiler to bring it back to the normal level (1 bar) – check the instructions that came with
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.
Heating System Has Been Overfilled. The first and most obvious problem that leads to high boiler … If your pressure gauge is marked with a green zone and the needle has fallen below it, this is a sign that the gas boiler pressure is too low and action should be taken. If you have radiators that fail to heat up as they should, this may also be a sign that there is an issue with your boiler pressure and can be confirmed by checking the gauge.
Most Common Reasons For Low Boiler Pressure. Here are the most common causes of low boiler pressure problems: Faulty Pressure Release Valve (PRV) Sealed systems have a release valve which is triggered when the pressure in the system becomes too high. The emergency release of hot water via this valve prevents damage to the system.
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.
Nov 19, 2017· A failed expansion tank would normally result in very high peak pressures, not low pressure. The PRV should never spit water- EVER, in normal operation. If it's been "normal" to fill a coffee can it's an indication that the expansion tank isn't properly pre-charged, or that it's too small for the water volume and temperature swings of your
If the pressure gauge on your boiler indicates high pressure (above 2.75 bar), then you may need to bleed a radiator to bring the level down to around 1.5 bar. This can be tricky and, occasionally, dangerous; due to high water temperatures. We recommend an engineer take a look if you are experiencing high pressure – this could be a result of
YOU DON'T the ASME /NBBI codes have certain requirements regarding boiler manufacturing and a high pressure boiler can cause severe damage if it is not properly designed and routine maintenance
