3000kg gas steam boiler, ZOZEN low nox gas-fired boilers provides environmental protection force for blue sky defence
The primary purpose of the boiler is to supply energy to the facility's operations – for comfort heating, manufacturing process, laundry, kitchen, etc. The nature of the facility's operation will dictate whether a steam or hot water boiler should be used. Hot water is commonly used in heating applications. Under these conditions, there is a wide range of ZOZEN hot water boiler products available.
With high-quality products and high-standard services, ZOZEN Boiler has been awarded the honorary title of “Quality Supplier” by Samsung Electronics, Juewei Food and other companies.

The former part of ZOZEN SZL coal fired boiler body is surrounded by membrane wall, its upper part connects with boiler drum and lower part connects with header, which forms a combustion chamber to absorb the radiated heat from furnace there are dense convection tube bundles between the back side of upper and lower drum, the high temperature smoke enters a separate economizer after flushing heat absorbing surface then discharge from chimney.
3000kg gas steam boiler, ZOZEN circulating fluidized bed boiler is a kind of energy-saving boiler type. Guided by the advanced design theory of design in the static state and reconstruction in the flow state, the boiler has the reasonable water circulation system and boiler structure based on the research and application of water circulation, furnace structure, material circulation system for efficient separation and return transportation, stage combustion technology with a better air distribution ratio, anti-wear and sealing energy-saving technology, ultra-low emission technology of high-efficiency desulfurization and denitrification. The boiler has technological advantages of coal saving, electricity saving, high operating reliability and ultra-low air pollutant emission, which makes its main performance, technological and economic indicators reach a high level in China.
3000kg gas steam boiler, ZOZEN has set up a total of seven process stopping points throughout the production process, which are strictly controlled by different engineers, independent of each other and supervised each other, so that problems can be found and solved in time. If any workpiece is unqualified, it cannot enter the next process, which is the quality control of the entire production process of ZOZEN.
According to the actual production demands of Lenzing (Nanjing) Fiber Co., Ltd., ZOZEN Boiler recommended the SZS series gas-fired superheated steam boilers. This series of steam boiler adopts the large-volume furnace to ensure the sufficient fuel combustion. Combined with an advanced low-NOx burner, it can easily achieve the low emission of NOx, which meets the environmental protection requirements of Lenzing Group. At the same time, in order to improve the boiler thermal efficiency, it not only uses the high-quality aluminum silicate fibers for the furnace body, but also uses high-temperature refractory mud for heat preservation. With the additional energy-saving equipment at the end of the flue gas duct, the boiler thermal efficiency is as high as 98% to save the operating costs.
As a well-known industrial boiler manufacturer, ZOZEN Boiler actively responds to the Belt and Road Initiative, pays attention to developing advantages of technology, brand and service, conforms to the global development trend, contributes to the economic development of the “Belt and Road” countries and regions with safe and efficient boiler equipment, and rapidly expands the overseas market.
