Guizhou Shuicheng Mining Co., Ltd. is a large-scale enterprise group focusing on the coal production and processing. Its business also covers the chemical processing of coal, electric power, coal machine manufacturing, etc. The company's mining area is mainly composed of the Shuicheng mining area and Zhina mining area, with rich geological reserves, complete coal types and good coal quality. Its main coal products include washing mixed coal, sieving mixed coal, anthracite and smelting refined coal, which are the ideal coal types for the electric power, chemical, building materials, metallurgy and other industries. This time, in order to further improve the coal product quality and production efficiency, Shuicheng Mining ordered a set of high-efficiency WNS series gas-fired steam boiler from ZOZEN, and achieved the desired effect of energy saving and emission reduction.
Research Center for Clean Energy and Power, Jiangsu and CAS is a provincial scientific research institution approved by the Office of Organization Establishment Commission of Jiangsu Province. It is responsible for the part construction of high-efficiency and low-carbon gas-fired steam turbine testing apparatus assigned to Jiangsu Province, which is a national key scientific infrastructure project whose impersonal entity is Institute of Engineering Thermophysics, CAS. In the construction, several small test beds required sufficient and stable steam support, so the Center purchased a set of high-efficiency and stable WNS series steam boiler from ZOZEN Boiler.
Bashi Chuanzhen Agricultural Development (Yiliang) Co., Ltd. is a raw materials processing base established by Sichuan Bashi Chuanzhen Food Co., Ltd. in Yiliang County, Yunnan Province. In the processing of agricultural products, blanching, sterilization and other processes need the stable heat supply provided by industrial boilers. A set of industrial boiler with sufficient output and stable heating has a direct influence on the daily production of the food enterprise. Therefore, Bashi Chuanzhen Agricultural Development (Yiliang) Co., Ltd. attached great importance to the purchasing of the industrial boiler. After having the in-depth communication with ZOZEN's professional technicians for many times, the company decided to order a set of DZL series biomass-fired steam boiler.
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.
In the pharmaceutical industry, the production and processing of many medicines require the sufficient and stable steam heat source with high quality. By virtue of abundant project experience in the pharmaceutical industry, ZOZEN Boiler reached a friendly cooperation with Zhejiang Haisen Pharmaceutical Co., Ltd. on the WNS series two-pass gas-fired steam boiler. Haisen Pharmaceutical is a high-tech enterprise engaged in the R&D, production and operation of APIs and pharmaceutical intermediates. The company's main products are APIs including sucralfate, analgin, pazufloxacin mesilate, atorvastatin calcium, paroxetine hydrochloride, escitalopram oxalate and pharmaceutical intermediates including PHBA, N-Methylparoxetine, etc.
Industrial boilers have been widely used in the chemical industry all the time. They play an indispensable role in the pretreatment, hydrogenation, decomposition, and distillation of oleochemicals. Hangzhou Oleochemicals Co., Ltd. was founded in 1973 (the predecessor was Hangzhou Grease Chemical Factory) is a state-owned enterprise which was invested and built by the former Ministry of Light Industry of China. The enterprise was restructured in 2000 and it is now a wholly-owned subsidiary of Zhejiang Zanyu Technology Group Co., Ltd. that has formed a style of simultaneous development of multiple products series. It supplies significant raw materials for manufacturing industries in food, chemicals, plastic, rubber, cosmetics, flavor and fragrance fields and deeply win trusts from many customers at home and abroad.
With the increasing environmental problems, environment-friendly gas-fired boilers have attracted more and more attention. In response to the situation, ZOZEN launched the WNS series gas-fired boiler product, which not only had outstanding environmental performance, but also helped many enterprises realize the goal of energy conservation. ZOZEN WNS series gas-fired steam boilers are horizontal wetback fire-tube boilers which have reasonable internal structure. An advanced low NOx burner is equipped with the boiler to reduce the NOx emission to less than 30mg/Nm3. At the same time, the burner can realize automatic air adjustment, which can ensure the sufficient fuel combustion. Through the commissioning of experienced ZOZEN technicians, the burner can achieve a good combustion state. In addition, the boiler has a large diameter furnace, which can further improve the combustion efficiency.
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
