heavy oil fired water tube boiler, ZOZEN effectively assists domestic and foreign customers to reduce operating costs and increase production efficiency
For ZOZEN Boiler, the so-called innovation not only refers to the innovation of boiler technology and products. More accurately, innovation is a kind of thinking. The innovation of products, enterprise system and marketing method keeps the sustainable development vitality of ZOZEN Boiler. It is also a destined way for the global industrial boiler industry.
Recently, data from the National Bureau of Statistics showed that China’s industrial boiler output from January to July in 2020 was 184,780.8 tph, a decrease of 24.8% year-on-year, showing a downward trend. Against the background of a sharp decline in the domestic industrial boiler industry, ZOZEN Boiler managed to overcome the difficulties and achieved a slight increase in output, heavy oil fired water tube boiler.
ZOZEN WNS series gas-fired (oil-fired) boilers are wetback fire-tube boilers with a two-pass or three-pass design. It uses threaded smoke tube for heat transfer and manages to achieve a thermal efficiency up to 98%. The economizer is installed at the tail of boiler, giving the boiler a compact size. Meanwhile, sound automatic control system enables unattended operation.
The outer packing of furnace body adopts for the whole frame structure to reduce the junction plates between the frame and the drums, which minimizes heat loss due to heat conduction. Advantages: save energy, reduce consumption and help customers reduce the costs.
The boiler hydrostatic test is a test of strength and tightness with pressurized water after the boiler or components are assembled. The main purpose of the hydrostatic test is to test the tightness and compression strength of boiler pressure-bearing components, tell whether there is leakage of welding seams, flange joints and pipe expansions, and watch the deformation conditions of pressure-bearing components with naked eyes. Practice has proved that the boiler defects can be found through the hydrostatic test, and the safety of boiler operation can be ensured after the corresponding measures are taken in time. Therefore, the hydrostatic test is an important step and means to ensure the safe boiler operation, heavy oil fired water tube boiler.
heavy oil fired water tube boiler, The complete set of WNS series gas-fired hot water boiler system customized by ZOZEN Boiler for Jilin Mingde Education adopts the corrugated furnace which not only increases the strength and flexibility of the furnace, but also enhances the flue gas disturbance to effectively improve the heat transfer effect. The threaded smoke tube with advanced manufacturing technology has been continuously optimized to effectively absorb the flame energy, and its heat transfer coefficient is 1.2 times higher than that of ordinary smoke tube. At the same time, with the additional finned tube condenser at the end of the flue gas duct, the exhaust gas temperature can be lowered and the boiler thermal efficiency can be as high as over 95%. According to the energy efficiency test conducted by the Thermal Energy Testing Center of the Special Inspection Institute, the performance indicators of the WNS series gas-fired boiler are higher than design requirements and have reached the advanced level at home and abroad.
It’s critically important to stay in lock step with your customers to understand how products need to evolve to continue to meet their needs. It’s easy to fall into the behavior of “milking” existing products. Products must continually evolve to remain relevant and useful. The path to success is through continual product innovation. It is the ZOZEN Boiler way, heavy oil fired water tube boiler.
