There are several kinds of function areas in school, such as the teaching area, bath area, canteen and dormitory, each area has different requirements on the hot water temperature. This time, Guyuan No. 8 Middle School ordered two sets of WNS series hot water boilers from ZOZEN Boiler.
In the processing of potato starch, the steam quality of desizing, dewatering and drying directly affects the quality of potato starch. Therefore, a set of steam boiler with good performance plays an important role in potato production.
Steam is necessary for general large-scale hospitals, and there is a great demand. Medical devices need steam for high-temperature sterilization; There are a lot of bed sheets and hospital clothes in the inpatient department every day, which need steam for cleaning, disinfection and drying; Hospital canteens need steam and hot water for cooking, cleaning and disinfection; In addition to heating in winter and supplying hot water, all these need strong support from steam boilers.
Established in 2010, Guangning County Guangan Paper Co., Ltd. is an enterprise which is engaged in the waste paper recycling and manufacturing. In order to meet the market demands, Guangan Paper planned to invest a new expansion project with an output of 50,000 tons of gray paperboard. This project needed to introduce the new paperboard production equipment and a set of coal-fired boiler, and upgrade the existing pollution treatment facility at the same time. By virtue of high efficiency and good environmental protection performance, ZOZEN SZL series coal-fired steam boiler successfully won the favor of Guangan Paper to provide the stable and reliable steam supply for its dewatering, forming, drying and other processes.
Heilongjiang Changfeng Coking Co., Ltd., founded in 2014, mainly produces coke, tar, crude benzene and other chemical products. In the second half year of 2019, the company invested more than 60 million RMB to launch a 6 MW coal gas thermal power project which required a set of 45 tph gas-fired boiler and the 6 MW condensing steam turbine generator set. If the project is put into use, it is expected to generate 60 million kWh of electricity per year and form a heat supply network covering 300,000 square meters, which is a municipal-level key industrial project and is highly valued by the local government. However, this set of steam boiler with a rated pressure of 3.82 Mpa and a steam temperature of 450℃ is a kind of A-grade mid-temperature and mid-pressure boiler, which sets high requirements for boiler design and manufacture.
Laiyang Fusheng Food Co., Ltd. is an enterprise engaged in the processing of agricultural and sideline products, whose business covers the preservation, refrigeration and sales of raw meat, raw meat products, aquatic products, fruits and vegetables. In September of 2019, Fusheng Food decided to launch a frozen food production and processing project which needed to pass the strict environmental assessment implemented by the local government. It included the environmental impact of the company's heating equipment which was used to generate hot water for the blanching process of semi-finished raw materials. Due to the strict air pollutant emission standards of Liyang city, Fusheng Food ordered a set of ZOZEN WNS series three-pass gas-fired steam boiler after a series of market investigation.
After the boiler was put into operation, the WNS series gas-fired hot water boiler would provide a stable heat source for the heating of agricultural greenhouses and living areas in our Science and Technology Park. The characteristic of high efficiency will greatly reduce our costs of heating supply.
The industrial boiler is very important for garment production lines of Shenzhou Knitting, which will directly affect the product quality and output. With advantages of boiler performance, ZOZEN became the heat source equipment supplier of Shenzhou Knitting and completed the manufacturing, installation and commissioning of the SZL series chain grate steam boiler. The boiler adopts a desulfurizer, a denitrator and an online monitoring device to achieve standard flue gas discharge. In addition, this series of boiler is a horizontal double-drum chain grate boiler. The furnace is composed of water-cooled wall, front arch, rear arch and furnace base. The large furnace not only reduces the heat load but also reduces furnace coking. Meanwhile, multiple independent wind chambers and air adjustment devices are equipped at the lower part of the boiler grate to supply enough air for fuel combustion. And, the fuel utilization rate is improved through precise air distribution. Besides, the SZL seri
