ZOZEN has focused on the research and development of chain grates for years and has obtained a number of patent technologies. With thermal efficiency over 82% and NOx emissions less than 100mg/Nm3, ZOZEN DZL series boilers have realized the high efficiency and low emissions goals. DZL series boilers adopt horizontal single-drum structure and a chain grate and take the lead in adopting arched tube plates and threaded smoketubes to increase heat conduction. The heat transfer coefficient of threaded smoke tubes is 1.8 times higher than ordinary tubes. In terms of manufacturing processes, ZOZEN adopts the pre expansion of smoke tubes and tube plates to eliminate the gap between them, and then adopts the welding process of argon arc automatic welding to effectively eliminate the stress and prolong the service life of the boiler. With above advantages, ZOZEN has been one of the most popular industrial boiler brands in the feed industry.
With increasingly stringent environmental protection policies, coal-to-gas boiler projects are progressing in an orderly manner across the country. In this process, ZOZEN WNS series gas-fired steam boiler with excellent environmental performance has been widely recognized and favored by the market. This series of gas-fired boilers adopts a large-diameter corrugated furnace, which can not only ensure the full combustion of the fuel to a certain extent, but also effectively absorb the thermal expansion. And the threaded smoke tubes have good thermal scalability, scientific airflow design, effectively absorb the flame heat, and combined with the energy-saving devices at the end of the flue, the boiler thermal efficiency can reach over 98%. In addition, in response to the low NOx emission requirements put forward by more and more enterprises, ZOZEN has selected international advanced low NOx burners to easily achieve NOx below 30mg/Nm3, and customized a full set of boiler system design sol
In the production process of foam packaging materials, the foaming, molding, drying and other technological processes require the stable steam generated by the boiler. Xin'an Baolilong Packaging Co., Ltd. specializes in the production of foam products, mainly used for the packaging of electrical appliances, furniture and a variety of building materials. With the development of the society, the market demand for foam packaging products continues to increase, Baolilong Packaging decided to expand production capacity and introduce a new gas-fired steam boiler. BaolilongPackaging put forward the requirements for the boiler: safety, environmental protection and high efficiency.
China produces more than 700 million tons of crop straw every year, which has become a new source of rural environmental pollution. Hebei Yigao Bioenergy Co., Ltd. and ZOZEN worked together to promote the efficient use of biomass energy such as crop straw. In 2018, Yigao Bioenergy built a number of new production lines, and its products are widely used in papermaking, xylose resin, adhesives, petroleum, pharmaceuticals and other industries. After the project was completed, it is estimated to consume 240,000 tons of biomass straw each year, becoming a demonstration project of comprehensive utilization of biomass straw.
ZOZEN has played an active role in promoting the process of "coal to gas". In particular, the WNS series of gas-fired steam boilers have gained a good reputation in the industry due to their safe and efficient performance. This gas-fired boiler features compact design and is equipped with boiler control, alarm and interlocking devices of water level and steam pressure to ensure safe and reliable boiler operation. And the large-diameter corrugated furnace and high-efficiency heat-conducting threaded tubes increase the heating surface. With the energy-saving device at the tail of the flue, the exhaust gas temperature is reduced below 60℃, and the thermal efficiency is as high as 98%, helping clients achieve their goal of energy saving and emission reduction.
Under the general trend of global economic green development, biomass-fired boilers use biomass-forming pellets such as crop straws and forestry residues as fuel have become the choice of many enterprises because of their environmental protection advantages. Among them, Hunan Leading Construction Technology Co., LTD., specializing in the R&D, production and sales of lightweight building materials, is an integrated supplier of various advanced application technologies. In the production process of high-precision aerated concrete blocks and plates, ZOZEN SZL series biomass-fired boilers provide a stable heat source for the autoclave curing process.
