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.

· Jan 28, 2015A much simpler approach would be to send water that has been pre-heated using solar energy to the combi boiler. A hot water cylinder is still needed to accumulate the solar heat through the day, but it can be smaller because it doesn't need a boiler-heated volume inside.
‘Pre-heat’ is a function that is designed to provide you with instant hot water when required. It works by infrequently heating the plate heat exchanger so that when hot water is requested it is already heated. This feature is not compulsory however, if not selected can take a few minutes before the hot water is at the appropriate temperature.
Worcester boiler - eco or preheat — MoneySavingExpert ForumSep 02, 2013Combi Boiler Hot Water Always OnJan 21, 2013Combi Boilers - Hot Water Preheat functionJul 31, 2011See more results · Mar 17, 2008Then running the cold water from my main through this and THEN out and into the cold water inlet of my electric water heater. So when burning wood, the heat from the wood stove would "pre-heat" or warm this water before it gets to my electric water heater. So less heating would be required from my water heater and a lower electric bill.
Pre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency.
How do I plumb a solar water heating system into a combination boiler? Here are two solar plumbing diagrams and a few words of advice to solar plumbers considering fitting solar a solar water heating system to a combi boiler.. I have put two solar combi plumbing diagrams below, because there are two types of combi boilers, when considered in terms of how control their flame size in response to
Preheating water for a steam boiler is, well, just heating water. Again, it take 970 times the amount of energy to turn water to steam than it does to raise a quantity of water 1 degree F. without any temperature differential at all.
However, whether the water in the tank is used for space heating or domestic hot water, it won't be hot water unless you have a way to heat it. There are lots of ways to do that -- you can use a boiler, a water heater, a heat pump, or solar collectors -- but you still need to heat the water if you want to use the water in the tank for space
Solar Panels for Domestic Water and Space Heating Pre-Heating into a Gas Combination Boiler Example. This solar system is designed to heat a tank with the solar panel and then when domestic hot water is called - pull it through a combi gas boiler (such as our Embassy ONEX Boiler).
