4 tons industrial steam boiler, ZOZEN boiler, a famous boiler brand of china has successively obtained a number of international certifications
After more than 30 years of development, Wuxi Zozen Boilers Co., Ltd. has made outstanding achievements in various industries. Recently, the ZOZEN WNS series gas-fired steam boiler has established a high-temperature sterilization safety line for the production of contact lenses, which has promoted the healthy development of the entire industry.
In the process of smelting molten steel, pouring steel ingots, and producing finished castings, a large amount of steam is consumed. The superheated steam generated by the boiler provides the required thermal energy for its process. Through open bidding, ZOZEN stood out among many boiler manufacturing enterprises with its own technical advantages and quality assurance, and provided China Second Heavy Machinery Group Corporation with a large superheated steam boiler.
ZOZEN molten salt heaters use molten potassium nitrate and sodium nitrite as heating media. Molten salt heater will heat the powder salt over the melting point until the viscosity of the molten salt allows circulating pump works, after the whole system is under circulating condition, then feed then into the thermal fluid heater for further circulating rising temperature to make it to be recycling used. Normal media working temperature is 400-550℃, top working temperature could reach 600℃.
Recently, ZOZEN YQW series thermal oil heaters gained favor of SOTRATECH in Mauritius, which is an energy company engaged in utilization and development of sustainable energy. This time SOTRATECH wanted to purchase one thermal oil heater for a local textile mill, providing heat energy for dying, printing, drying and other production progresses. The director of SOTRATECH said that ZOZEN thermal oil heater featured advanced production technology and strict quality test standards, then he ordered a set of 2.8MW YQW series gas-fired thermal oil heater from ZOZEN.
4 tons industrial steam boiler, 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 is the first in China to adopt arched tube sheet and threaded smoke tube structure. Threaded smoke pipe is a high-efficiency heat transfer element researched by ZOZEN for many years. After continuous optimization, its heat transfer coefficient is 1.8 times higher than that of ordinary smoke pipe, which increases heat conduction.
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, 4 tons industrial steam boiler.
