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.

In 2019, Jiangsu Provincial Government introduced the policy to promote the transformation and upgrading of the iron and steel industry and steel enterprises were encouraged to conduct innovations on the manufacturing technology and upgrade the production equipment to realize the intelligent and green manufacturing. In order to actively respond to this policy, Ruisin introduced a set of eco-friendly WNS series three-pass gas-fired steam boiler from ZOZEN Boiler to satisfy the heating demands of the production line and achieve good energy-saving and emission-reduction effects.
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.
Worldon (Vietnam) Co., Ltd. is an overseas project of Shenzhou International Group and is a clothing company with the concept of green production. The company, fully established and put into production in 2016, mainly produces the knitted garments of international brands such as Nike, Uniqlo, Adidas and so on. In order to meet the increasing production demands and cut the production costs at the same time, Worldon (Vietnam) Co., Ltd. successively purchased 3 sets of high-efficiency and energy-saving SZL series chain grate coal-fired steam boiler from ZOZEN, which effectively improved Worldon's production capacity and product quality, and also realized the goal of energy saving and emission reduction to help Worldon fulfill the green production.
