fire tube boiler assembly, ZOZEN biomass-fired boiler has good quality
fire tube boiler assembly, As a leading manufacturer of industrial boilers, ZOZEN has a network of sales around the world. Recently, ZOZEN mid-temperature and mid-pressure steam boiler project in Bangladesh was in full swing.
In March 2019, Wuxi Zozen Boilers Co., Ltd. successfully passed the French BV certification and became an in-depth factory inspection company of Alibaba International Station. Alibaba cooperated with the French BV certification and comprehensively judged companies' product capabilities, quality control, research and development capabilities, and trade capabilities, which further proved that ZOZEN's comprehensive strength is strong, and all indicators fully meet the boiler export certification standards.
fire tube boiler assembly, 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.
fire tube boiler assembly, ZOZEN 4 tph WNS series oil-fired fire tube boiler for construction industry in South Africa. Pholaco is a construction materials company specializing in light steel frame (LSF) construction, EPS panel construction, and CLC (cellulose lightweight concrete) construction. ZOZEN provided 4 tph WNS series heavy oil fired boilers for the company. This kind of fire tube boilers adopt large corrugated furnace for full fuel combustion. In combination use of the thread smoke tubes, the thermal efficiency is up to over 98%.
ZOZEN WNS series gas fired boiler not only adopts advanced low NOx burners. And through the flue gas recirculation technology, about 10% -30% of the flue gas at the tail of the boiler is sucked into the air inlet of the burner through the flue gas pipe, mixed with the combustion-supporting air, and then entering the furnace, thereby reducing the temperature and oxygen concentration in the combustion area, and finally reducing The amount of thermal NOx is generated, and the NOx in the tail gas of the boiler are less than 30mg/Nm3, which meets the requirements of low nitrogen emissions of the enterprise.enterprise.

ZOZEN thermal oil heater is equipped with a variety of waste heat recovery devices. The heat loss is reduced through the recovery and utilization of high temperature flue gas waste heat, and the overall thermal efficiency of the thermal oil heater is increased to more than 95%, which is better than the overall industry level.
Be it a firetube, watertube, hot water, or steam boiler, they are all effective and efficient in their own unique ways. To learn in more detail about the differences between boiler types, visit the section on ZOZEN website.
