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
For a long time, steam boilers have played an indispensable and important role in the production lines of various feed enterprises. Established in 1996, Guangdong Yuanxin Feed Industry Co., Ltd. is a company integrating R & D, production and sales of livestock, poultry, aquatic products and bullfrog feed. With the rapid development in recent years, the market share of Yuanxin Feed has continued to expand, and the company needed to purchase new steam boilers to meet the actual needs of the production line. Based on the mutual understanding and trust, Yuanxin Feed purchased boiler equipment again from ZOZEN on the SZL series chain grate steam boiler.
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.
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.
In the manufacturing process of automobiles, the painting process has the effect of rust prevention, corrosion protection and decoration. The metal surface treatment before painting and the painting process require the heat source provided by the steam boiler. ZOZEN WNS series gas-fired steam boiler obtains advanced manufacturing technology. The fully automated production line ensures the uniform size of the boiler components, realizes the assembly between the components, which effectively extends the service life of the boiler. In addition, in order to improve the overall thermal efficiency of this type of boiler, ZOZEN technicians have improved the boiler design. Large-diameter corrugated furnace and high-efficiency heat-conducting threaded tubes, combined with the energy-saving device at the tail of the flue, ensure that the exhaust gas temperature below 60℃, and the thermal efficiency is as high as 98%, which reduces fuel costs for enterprises.
Hebei Anguo Modern Traditional Chinese Medicine Industrial Park takes modern Chinese medicine and healthy food as the leading industriies. The industrial clustering advantages and perfect infrastructure conditions have attracted many enterprises such as Tong Ren Tang, Tasly and China National Traditional Chinese Medicine Co., LTD. The concentrated supply of high-quality steam provides sufficient heat for the drying, extraction and stewing of traditional Chinese medicines. Therefore, these enterprises have strict requirements on the performance in various aspects of steam boilers.
SZL series steam boiler is a longitudinal double-drum chain grate water tube boiler designed by ZOZEN on the basis of advanced international technology and its own experience. 6-35 tph is shop-assembled structure, which is composed of 2 parts, upper part is heat absorbing surface and lower part is combustion equipment. the combustion air system (base) adopts independent compartment and scientific sealing structure; reasonable air conditioning device improves combustion efficiency. The water membrane wall, the front and rear arches and the hearth constitute the boiler furnace, A bank of return convection tube bundles are arranged at the rear of the boiler body to sufficiently absorb the heat released by the combustion. The SZL series chain grate steam boiler system customized by ZOZEN has excellent performance and the thermal efficiency is more than 5% higher than the similar boiler system on the market.
Sichuan Energy Investment has always formed a profound cooperation with ZOZEN. As an important window for opening up to the northeast of China and participating in the international specialization, Suifenhe has developed into a large-scale Russian wood import and distribution center. With the rapid development of the wood import and export processing industry, the ZOZEN SZL series biomass steam boiler project was installed here, providing concentrated steam for wood drying of wood processing enterprises in the Sino-Russian trade zone.
