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 4-6t/h boiler is of quick fitting tube structure, exit shop after completely assembled, the boiler of 6-35t/h is composed of 2 main components. The upper assembled component is the boiler proper heat absorbing part, and the lower assembled component is of combustion equipment.
Waste Heat Boiler Market Size, Share and Global Trend By Type (Water-tube Boiler, Fire Tube Boiler), By Heat Source (Oil Engine Exhaust, Gas Engine Exhaust, Gas Turbine Exhaust, Incinerator Exit Gases, Kiln & Furnace Gases) By Temperature (Medium, High, Ultra-High), By Orientation (Horizontal, Vertical) By End-Use Industry (Power Generation, Oil & Gas, Chemical & Fertilizer, Steel, Petroleum
What is a Boiler: Introduction to Boilers A boiler is an enclosed vessel that provides a means for combustion and transfers heat to water until it becomes hot water or steam. The hot water or steam under pressure is then usable for transferring the heat to a process.
Water Treatment. ChemSol supplies chemicals for boiler and cooling systems as well as waste water treatment. We offer a wide range of corrosion inhibitors, oxidizing and non-oxidizing biocides as well as products for closed loop treatments.
Apex Engineered Products is a proven supplier of heat transfer equipment primarily to the Nitrogen and Phosphorus based Fertilizer Industries and the General Chemical markets. Material compositions include Reactive Metals ( Ta, Ti, and Zr ), Ni Alloys ( VDM Alloy 31®, Hastelloys®, Inconels® ) and Duplex and Austenitic Stainless Steels; all of which offer resistance to highly corrosive

ABSTRACT: The boiler tube failure is occurring frequently in fertilizer plants, power plants, sugar manufacturing plants, paper manufacturing plants and all industries using boilers. The present study is related to the boiler tube failure analysis of three Boilers which are under operation at National Fertilizers Limited Naya Nangal.
Promoting the efficient growth of the fertilizer industry. Increasing efficiency and uptime is critical for fertilizers manufacturers today. Alfa Laval can help cut energy costs, reduce problems with fouling and corrosion and recover waste heat for reuse in the other plant processes.
Jan 28, 2018· Boiler is used to generate steam which is used for different processes as a heating medium and also to generate power. I personally visited following type of industries which use boiler. 1. Chemical Industry 2. Pharmaceutical Industry 3. Fertilize
Boiler inspections are crucial for any industry that uses industrial boilers as part of its regular operations. Boilers operate under extreme pressure and extreme fluctuations in temperature, often undergoing swings in temperature of hundreds of degrees Fahrenheit.
Wedgworth’s Inc., an industrial fertilizer manufacturer in Clewiston and Lake Placid, Florida, used a gas-fired boiler system to meet the hot water needs of its production processes in both facilities. In recent years, management found three problems with its boiler system: Boilers had poor service availability, with only one or two professional contractors in the area capable of handling
