what is draft in boiler, ZOZEN automatic thermal oil heater with excellent technology occupies the maeket of the chemical industry
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 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, what is draft in boiler.
The function of CFB boiler secondary air: Ensuring that the combustibles overflowing from the dense phase zone will be further oxygen-enriched in the lean phase zone (suspension section), so that the fuel is fully burned in the furnace and the temperature difference between the upper and lower furnace reduces.
Generally, the consumption of the steam boiler fuel in the textile industry is relatively large. Therefore, the steam boiler that provides thermal source is very important. ZOZEN customized the SZL series coal-fired chain grate steam boiler system for Xindadong Textiles (Vietnam) Co., Ltd. on the basis of the local conditions of Vietnam and the actual needs of users. This series of boiler has the advantages of high efficiency, strong overload capacity and wide adaptability of fuel types.
what is draft in 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.
With the application of patented technology in chain grate furnace, ZOZEN has realized the high efficiency and low emission of DZL series steam boilers. The thermal efficiency can reach 82% and NOx emissions can be less than 100mg/Nm3, which not only improves the combustion efficiency but also reduces the operating costs and pollution emissions of enterprises.
ZOZEN Boiler provides temporary and permanent solutions with our profession for industrial boilers to meet the most stringent emissions requirements. If you need more information, please contact us today.

Behind industrial manufacturing often lies an invisible thermal energy lifeline. Whether boiling syrup, synthesizing chemical materials, or pressing new energy security materials, every physical and chemical change on the production line has strict requirements for the temperature, pressure, and continuity of thermal energy. When green biomass energy enters these vastly different manufacturing workshops, how can various forms of pellets, wood blocks, or straw be converted into the "precise temp...08 Sep 2026
