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.
Ø Boiler Oxygen Scavenger is a catalyzed oxygen scavenger in a liquid form based on catalyzed sodium bisulfite. It helps to instantly remove oxygen from the boiler feed water by converting itself to sodium bisulfate and also reduces alkalinity.
Any oxygen allowed to enter the pre-boiler and boiler systems can lead to severe corrosion and result in potential system failures and downtime. Our 3D TRASAR™ oxygen scavenger chemistry works with our automated monitoring and control to minimize oxygen corrosion and improve system reliability.
Feb 02, 2018· Boiler Water Oxygen Scavenger is a catalyzed oxygen scavenger in liquid form based on catalyzed sodium bisulfite. Oxygen scavenger chemical helps to …
Food grade catalysed oxygen scavenger for steam raising plant, hot water systems and boilers. Accepta 2501 aids the rapid removal of dissolved oxygen, prevents pitting corrosion of heat exchange surfaces, and can be used in boiler plant up to a pressure of 46 bar
What is an Oxygen Scavenger? The purpose of an Oxygen Scavenger to to remove the dissolved oxygen in the make-up water or where dissolved oxygen. Oxygen in water is extremely corrosive and becomes worse at higher temperatures and pressures. For 95% of most boiler chemical applications, sodium sulfite is used in either powdered or liquid form.
Common Chemicals Used in Boiler Water Treatment Boiler water treatment is the conditioning and treatment of boiler feed water with the purpose of meeting three objectives. In order for boiler water treatment to be maintained, there must be a continuous heat exchange, protection for high-quality steam, and corrosion protection.
Multifunctional Boiler Water Chemicals. This range of chemicals are all in one boiler treatments which incorporate a boiler water oxygen scavenger, alkalinity builder, polymer sludge conditioner and, where appropriate, a phosphate treatment. They are matched to the feed water quality to ensure that the correct boiler water chemistry is achieved.
User rating: 4.6/5 Oxygen Scavenger is specially formulated with catalyzed materials to provide immediate removal of oxygen in boiler feed water systems. Efficient chemical deaeration can eliminate the small quantities of oxygen remaining after the most effective mechanical treatment, that can cause localized pitting in …
Preventing Boiler Corrosion is done through the removal of oxygen and maintaining appropriate alkalinity levels in the boiler water to prevent acid attack.. As shown in the chart oxygen levels are tied to the Hotwell feed water temperature with nearly all oxygen gone by the time the water reaches 100 o C. For this reason, we recommend keeping the temperature above 80 o C and incorporating an
The range of products include - Boiler Feed water treatment chemicals, Boiler internal treatment chemicals, corrosion inhibitors, pH boosters, antiscalants, oxygen scavengers, descalants, etc. These chemicals are used in water treatment plants, process boiler steam generation, water purification and food processing units to eliminate scales and
