Since the beginning of 2020, with the support of county government, Luanchuan County Thermal Energy Co., Ltd. has continuously improved the heating equipment and service quality to promote the central heating business in Luanchuan County. In September of 2020, the company organized the public bidding for the second phase of the central heating boiler room project in Luanchuan County. The company planned to introduce a set of energy-efficient gas-fired hot water boiler and clearly required that the NOx emission concentration of the hot water boiler should be less than 30mg/Nm3. This time, due to the high thermal power and good environmental protection performance of the SZS series gas-fired hot water boiler, ZOZEN Boiler successfully won the bid.
Shangqiu Municipal Hospital is a national public comprehensive hospital integrating medical treatment, teaching, scientific research, prevention, rehabilitation and elderly care. With the expansion of the hospital, the original heating equipment gradually could not meet the demands, so the hospital ordered a set of high-efficiency and energy-saving WNS series gas-fired steam boiler from ZOZEN Boiler. This series boiler had sufficient output, produced high-quality steam and operated stably, which provided a reliable guarantee for the daily disinfection and sterilization work of the hospital.
Shijiazhuang Huayuan Mineral Wool Board Co., Ltd. was founded in 2003. Its decorative sound-absorbing mineral wool board is popular and is widely applied in the interior decoration of various buildings such as cinemas, auditoriums, conference halls, etc. There are increasingly higher demands for the sound absorption effects of buildings, which also puts forward higher requirements for the production technology of decorative sound-absorbing mineral wool board. The production of sound-absorbing mineral wool board mainly adopts the wet processing whose dewatering and drying processes require the stable heat source provided by industrial boilers. In order to further improve the product quality, Huayuan Mineral Wool Board decided to introduce a set of ZOZEN YQW series gas/oil-fired thermal oil heater.
In the production process of aerated concrete products, the high-temperature steam curing of the aerated concrete body is an important process which can directly affect the product yield. The appropriate temperature for the autoclaved curing of aerated concrete is above 175℃, and the heating equipment includes the autoclave, precuring kiln and so on, which requires the efficient and stable steam boiler to provide heat energy. Anhui Guangrun New Building Materials Co., Ltd. is an enterprise specialized in the production of lightweight autoclaved aerated concrete (ALC) products. In order to improve the production capacity and optimize the production efficiency, Guangrun New Building Materials ordered a set of WNS series three-pass gas-fired steam boiler from ZOZEN Boiler, as the heating equipment in the production of aerated concrete products.
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.
In order to realize green production and environmental protection effects, Longwang Food decided to purchase the natural gas steam boiler and sets strict requirements for the eco-friendly performance of boiler. After knowing the huge steam demands of Longwang Food's diary and soybean products production lines, ZOZEN Boiler recommended the SZS series gas-fired saturated steam boiler which has sufficiency output, high thermal efficiency and outstanding eco-friendly performance.
Emeishan Tonghui Pharmaceutical Co., Ltd., founded in 2002, is a modern pharmaceutical enterprise integrating scientific research, production and sales with workshops for freeze-dried powder injections, small-volume injections, and solid preparations. With the continuous expansion of the production scale, the company's old boiler equipment could not meet the heating demands of the pharmaceutical production line. Therefore, after a series of market investigation, Emeishan Tonghui Pharmaceutical decided to introduce a set of WNS series gas-fired steam boiler designed by ZOZEN Boiler.
