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.
The CTD & CTD-S Water Tube Boilers utilize the modern design of a “D” shaped design, consisting of two drums that are mounted at the top and bottom of the boiler with expanded vertical tubes surrounding the furnace chamber. The CTD-S is our lower steam production boiler, which is delivered as a packaged model of the CTD.
the problem could be the valve but mire likely a boiler over pressure condition or a water feeder probkem. Diagnose the cause before replacing parts. On 2015-12-16 by Paul . There is water FLOWING from the DISCHARGE TUBE on my Triangle Tube, indirect fired water heater. (I shut of the water supply off to the tank so it isn't spilling onto the
This category contains a variety of Aluminum Pilot Tubing. Aluminum Pilot Tubing connects the pilot assembly to the burner. If you're pilot tubing is leaking a small amount of gas, it is possible the Tubing has been damaged and needs to be replaced.

User rating: 5/5 How a Water Tube Boiler Works. One of the latest advances in steam production technology is the use of water tube boilers. This type of boiler is distinct from conventional boilers that use a fire tube system. Water tube boilers are more efficient than fire tube boilers, generating more steam but using less fuel.
Introduction. WNS series horizontal internal combustion boiler is classic 3-pass wetback oil/gas fired boiler. After fuel is atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, called 1st pass; the high temperature flue gasses are collected in reversal chamber and then enter 2nd pass, which is grooved tube bundle area through heat convection, air
Trade Description: A boiler hot water heating steam fitting contractor installs, services and repairs power boiler installations, hot-water heating systems and steam fitting, including fire-tube and water-tube steel power boilers and hot-water heating low pressure boilers, steam fitting and piping, fittings, valves, gauges, pumps, radiators, convectors, fuel oil tanks, fuel oil lines, chimneys
The gauge glass allows the boiler operator to see the water level in the boiler. Normally there are two valves associated with the gauge glass. One valve is located at the top and one is located at the bottom of the gauge glass. These two valves, named gauge cock valves (fig. 1-6, item 2). secure the boiler water and steam from the gauge glass.
Boiler tubes for higher temperatures, diameters from 10.2 to 139.7 mm, wall thickness from 0.5 to 16 mm, length 5 – 22 m.
Author: Keith Appleton The boiler controls should operate as for lowered water level in boiler i.e. pump running and / or audible alarm sounding and burner cut-out. Alternatively if the level control chamber is fitted with a second or extra low water alarm, the boiler should lock-out.
