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.
These are less common fuel types applied by environmentally progressive companies that utilize items like wood chips, corn husks, and various plant materials that surprisingly can be used to fuel boilers. When it comes to selecting a boiler based on the fuel it uses, it’s best to find a boiler that can operate on more than one type of fuel.
Best Condensing Boiler Fuel Mix. You want a system known to mix in its fuel within the combustion chamber with the highest efficiency possible. You also want fuel delivery to the boiler to be optimal efficiency. This is not easily assessed by a lay person, and may be worth either educating yourself about what the more advanced system efficiency numbers mean, or having a friend who knows
Sep 25, 2017· The system contains a robust fire tube heat exchanger and is fully modulating to save fuel. The natural gas or LP-fired unit is offered in many sizes and configurations, including 120-, 140-, and 199-MBtuh combi boilers and water heaters, or as 80-, 100-, 120-, 140-, …
Worcester Bosch Greenstar i. The Worcester Bosch brand is a long established UK brand which is … Oct 14, 2016· For control valves, we want a linear installed flow characteristic, an 86% response less than 4 seconds, deadband less than 0.3%, and resolution better than 0.2% for small steps (e.g., 0.5%) and medium size steps (e.g., 5%). This performance is best achieved by using diaphragm actuators, sliding-stem globe valves and low-torque butterfly valves.
How To: Stop Boiler Noise. The central heating system or boiler is clunking or otherwise noisy. About the problem. Boiler noise, or ‘kettling’, has a number of potential causes, and these can be divided into chemical and mechanical factors. Chemical factors. Foaming.
Low nitrogen oils can contain up to 15-20 times less fuel-bound nitrogen than standard No. 2 oil (less than 0.001% fuel-bound nitrogen). When low NOx oil is fired in firetube boilers utilizing flue gas recirculation, NOx reductions of 60%-70% over NOx emissions from …
Fuel Oil. Oil is also a conventional fuel in areas where natural gas is unavailable, particularly in northeastern states and eastern . Canada. As with propane, there will be a tank located on the property, and periodic fuel deliveries will be required. In rural areas that have available wood, coal, or other biomass, solid fuel boilers may be an
Noise. Every boiler makes a sound, and some are much louder than others. In the tables above, we’ve expressed noise as a star rating (the higher the rating, the less noise), but down in the more technical tables below, you’ll see it written in decibels (dB). If this bamboozles you, know that normal conversation tends to range between 40
If the AFUE is 90 percent, then 90 percent of the heat created by burning the fuel is used for heating your home while the other 10 percent escapes — thus, having a higher AFUE means that you need less fuel to heat your home, saving you money instantly (see our previous article on energy efficiency acronyms for more info). When looking for a
What’s causing the boiler noise? 1. Mineral Deposits. This is one of the most common causes of boiler noise. A typical boiler usually works at 180 degrees Fahrenheit, which is just below the boiling point of water. Over time, this may cause the boiler tubes to collect deposits of hard water.
Most industrial and commercial users of packaged boilers now fire natural gas. You’ll find #2 oil commonly used as a back-up fuel for hospitals and industry, and in some geographic areas without natural gas service. This information is intended for use by the vast majority that fire natural gas and also touches on #2 oil.
