Introduction of WNS gas / oil fired steam boiler:

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.

Technical advantages:

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.

How dangerous is it if your boiler pressure is well hi

Feb 02, 2010· The boiler should have a low pressure and high pressure cut out built in, so there should be no need to panic if your unsure, your boiler will just fail to ignite and deliver hot water. If your getting hot water and no heating (or vice versa) you could have a knackered thermocoupler which isn't a pricey (£10-ish) or tricky job to replace

How to Set Hot Water or Steam Heating System Pressu

If we set the boiler upper temperature too high over 200 degrees F. we're at risk of spilling at the pressure temperature relief valve. If we set the boiler upper limit too low, there may be no relief valve problem but under some conditions we may reduce the operating efficiency of the boiler and heating system, thus increasing heating costs.

High Pressure Boilers 2 - ProProfs Qu

High Pressure Boilers 2 . When cooling down a steam boiler that has been taken out of service, a vent valve on the steam drum should be opened to prevent what from occuring? A. An over pressure condition. B. A vacuum. C. Too much condensing of the steam. D.

How do I adjust my boiler pressure properly? – Energui

The pressure gauge needle indicates the actual pressure of the system. A green zone shows the correct pressure range, while a red zone shows the critical zone.: A red needle serves as a marker, while a black needle corresponds to the actual pressure.These two needles should be on top of one other.: In some boiler models, the water pressure is given by indicator lights on the control panel.

Boiler water pressure too high | Terry Love Plumbi

Feb 15, 2011· Most boilers have a low-pressure cutout switchit must be above that or the boiler won't fire (risks flashing into steam), and they also have a T&P valve that will open if the pressure or temp gets too high. On a boiler, that pressure could be as low as 30-pounds, or it …

Why is phosphate dosing done in a boiler? - Quo

Apr 19, 2018· Phosphate is doing interesting job in Boiler. It works as an anti-scalant since phosphate react with calcium hardness to create suspended solids (which is easier to discharge via blowdown) in order to prevent any calcium carbonate (CaCO3) /calcium

Steam Power II Test #1 Flashcards | Quizl

When a high pressure turbine is operating at sea speed, the pressure of the steam leaking through the shaft gland packing may be slightly higher than the pressure setting of the gland seal regulator. In this situation, the excess steam at the regulator is directed to the _____. a) gland exhaust condenser b) excess steam condenser c) main condenser

Boiler Pressure Too High - Why it Matters if There is T

If your boiler pressure is too high, it will not work effectively. Similarly, if the boiler pressure is too low, you will struggle to fuel your central heating and hot water. The ideal boiler pressure is usually within a narrow range and anything higher or lower is generally cause for concern. Keep reading to find out

Boiler Pressure Too High: How to Reduce it | Living

Author: steven lavimoniere When the heating is turned on, your boiler pressure should be between 1.5 and 2 bars. Most boilers will highlight this area in green on the pressure gauge, clearly showing you that the pressure setting is correct. Why is my boiler pressure too high? Once the boiler begins to heat water, the heated water expands and causes the pressure gauge to
