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.
Apr 04, 2011· I see most often recommendations of 8.5 - 9.5, although I've also seen as low as 7 (neutral) and as high as 11. It seems to be most important that you are not in the acid range (below 7.0). If you are concerned about your boiler water, pH is only one of the items, although a very important item, that needs to be considered.
It is blowing down boiler water by operating the blowdown valve and replenishing the amount of water blown down with fresh water is of the vital importance of reducing the concentration of boiler water to a satisfactory level for operation. It is Also, as important to discharging sludge, oily substance, and other impurities accumulated in the boiler.
Jan 26, 2018· > Natural water is usually between 6.5 and 7.5 pH. A common recommendation is to maintain boiler water at 8.5 pH.Acidic water is corrosive. Alkalinic water is more prone to scaling.Alkalinity is a measure of the bicarbonate (HCO3), carbonate (CO3
A boiler is a closed vessel where water under pressure is transformed into steam by the application of heat. This process is useful for a variety of industries, from industrial and manufacturing environments to food and beverage processing. In the boiler furnace, the chemical energy in …
Click to view1:17Nov 07, 2016· Keep the corrosion to a minimum in your steam boiler? Keep the pH between 8.5 and 9.5 Here is how you check the pH of your boiler water. Easily done. No problem. Take a look.
As water flows throughout the boiler its chemical properties can damage the system so feedwater is often treated to control alkalinity, prevent scaling, correct pH, and to control conductivity. Failure to treat the feedwater can adversely impact the efficiency and lifespan of boiler components.
The choice of a pH sensor for boiler water monitoring depends primarily on the conductivity of the boiler water. Conductivity can range from 7000 uS/cm in a low pressure industrial boiler to under 10 uS/cm in a high pressure boiler in a steam power plant. A pH sensor that works fine in …
The safe pH range for steam boilers is between 8.5pH & 12.7pH, whilst the recommended level is between 10.5pH & 12.0pH. Boiler water with a pH of 10.5 contributes 12.6mg/l towards the boiler TDS, whilst at a pH of 12.0 it increases to 400mg/l and at 12.5pH the value is 1264.9 mg/l a 100 fold increase.
