With a large flow of tourists, Zhengzhou Railway Station is one of the eight transportation hubs in China. It is known as the heart of Chinese railways. The comfortable waiting environment comes from stable heating system. It is Zhengzhou Heating Company Second Road Heat Source Factory that provides stable heat source for Zhengzhou Railway station. Founded in 1989, the heat source factory was put into operation in 1992. In recent years, with the aging of old boilers, the thermal efficiency of the existing 4 sets of 20 tph chain grate steam boilers has been gradually reduced. Besides, considering environmental protection and other factors, Second Road Heat Source Factory decided to implement the Coal-to-Gas Project, dismantle the existing low-efficiency and high-consumption coal-fired boilers, and introduce some sets of SZS series gas-fired steam boilers.
This time, Jilin Deda purchased a branch of ZOZEN WNS series gas-fired boilers for demands of meat production and workers' heat supply. This type of gas-fired steam boilers adopts horizontal internal combustion wetback structure with novel design and rational structure. The burner flame is burning in large-diameter corrugated furnace in slight positive vacuum condition. It combined with high-efficient threaded smoke tubes and scientific furnace heat preservation design that can effectively improve thermal efficiency to more than 98%, which is superior to the national Level 1 energy efficiency standard and can realize the expected energy-saving goal of Jilin Deda. Besides, the advanced automatic control system can realize automatic start-stop, load adjustment, water supply and other operations according to the demands of users. With features of easy operation and low failure rate, the control system is both safe and reliable.
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.
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.
In food processing enterprises, steam boilers provide a stable heat source for the baking and frying, high-temperature sterilization of food ingredients. Sichuan Aning Food Co., LTD. is a snack food enterprise which mainly manufactures sauce and halogen food.
Steam boilers are essential in large hospitals, which are used to sterilize and disinfect medical equipment, hospital bed sheets, quilts, etc. and provide steam for washing machines and dryers in hospitals. Nanyang Second General Hospital is a three-level general hospital with more than 2,000 beds and over 80 clinical and medical technology departments. Therefore, the hospital has a large demand for steam. In response to the national green development concept, People's government of Henan province decided to repurchase a gas-fired steam boiler for daily sterilization and disinfection. Serving as a place of healing the wounded and rescuing the dying, the hospital has high requirements for the quality of steam and the stability of boiler operation. The project leader of Nanyang Second General Hospital was attracted by ZOZEN's perfect production line and strict quality supervision after inspecting many well-known boiler plants.
Charoen Pokphand Group is a well-known multinational company founded by a Thai Chinese, also known as the CP Group, its output value and scale are both the leaders of the industry. In 2016, CP Group invested Jilin Chia Tai Food Co., LTD. to expand its scale, which has an annual processing capacity of 100 million broilers. During the processing of broilers, whether the disinfection & distillation, baking & stewing, or heating & drying, the heat source provided by the the steam boiler is required. In order to purchase a set of high-performance and low-emission boiler, CP Group carried out a public bidding.
