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.
Nov 03, 2017· What decides the hot water temp coming from the taps of a combi boiler? Is it the flow rate of the water slowed down to make the water hotter or is the gas flame increased in intensity? The same with the temperature for the radiators.

Boiler Piping Flow & Pipe Sizing - It is important that the correct pump is selected in hot water boiler loops so that the correct velocity is achieved throughout the system. Too much velocity and the system will not be efficient because of Laminar flow issues.
Author: Viessmann Installer Nov 05, 2015· Flow Rates & Boiler Power Requirements. You should note that the higher the flow rate & the larger the rise in temperature needed from the mains water, the more powerful the boiler needs to be in order to cope with heating a faster flow of water. If you want hot water at 9 litres per minute, what amount of heating power do you need from your
Click to view3:27Nov 07, 2013· Boiler on, but no hot water? The fix can be easier than you think. Al the plumber takes you through it step by step. For plumbing spares visit my Amazon shop
As with any hot water or heating appliance, a hot water boiler system requires a constant pressure flow to maintain the optimum temperature. Hot water boiler systems are equipped with a pressure gauge and an automatic pressure reducing valve that will add water to the system if the pressure drops.
Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses.. Domestically, water is traditionally heated in vessels known as water heaters, kettles, cauldrons, pots, or coppers.
Gravity Hot Water Heating Systems. A gravity hot water heating system is the oldest and simplest …
Sep 25, 2012· Inefficient Hot Water Piping Layouts Waste Hot Water that the maximum volume of water in the pipe between the water heater and a tap shall be 64 ounces; a requirement (for some residential applications) that the maximum length of piping between a water heater and a tap be restricted to 50 feet for 3/8-tubing, 43 feet for 1/2-inch tubing
