Recently, ZOZEN Boiler and Kenya Pipeline Company (KPC) have reached a cooperative relationship in the WNS series oil-fired steam boiler project. At present, this batch of boilers has been successfully shipped to Kenya, and the ignition commissioning has been completed. Established in 1973, the Kenya Pipeline Company is one of the large state-owned petroleum processing and transportation companies in Kenya, and plays a key role in promoting the economic development of Kenya. In order to meet the requirements of Kenya Pipeline Company for using heavy oil as fuel, ZOZEN Boiler has customized a boiler technical solution for Kenya Pipeline Company: the boiler body adopts the WNS series three-pass wet back, so that the high-temperature oil smoke gas can stay longer in the furnace.
In addition, combined with the large-diameter full-waveform furnace, the thermal efficiency can reach more than 98%. At the same time, it is equipped with a specially designed heavy oil combustion device to improve the combustion performance of heavy oil.
Heavy oil is the remaining heavy oil after crude oil is extracted from gasoline and diesel, and has the characteristics of large molecular weight and high viscosity. In this case, ZOZEN Boiler installed a filtration system and heating device for the Kenya Pipeline Company to ensure the smooth transportation of heavy oil and good atomization, and achieve the full combustion of fuel, thereby saving operating costs. The cooperation between ZOZEN Boiler and Kenya Pipeline Company in Kenya is of benchmark significance for ZOZEN Boiler to further expand the African industrial boiler market.
Technical characteristics of wns boiler
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 annual production scale of Wuxi ZOZEN Boilers Co., Ltd. has exceeded 2,000 sets since its establishment in 1988; ZOZEN has obtained PRC Grade A Manufacture License of Special Equipment, PRC Grade BR II Manufacture License of Special Equipment, ASME “S” (Power Boilers) and “U” (Pressure Vessels) stamps and passed IS09001:2000. In Africa, ZOZEN has provided boiler system solutions for users in the agricultural, chemical, food and other industries.
