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.

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.
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.
China CEC Engineering Corporation is a large-scale engineering consulting and design company. Its main business covers engineering design, consulting, supervision and general contracting. It provides services for pulp and paper, energy and environmental protection, salt manufacturing and salt chemical engineering, household appliances, food, construction, municipal and other industries. In order to meet the demands of the project to construct a comprehensive PVC resin production plant with an annual output of 60,000 tons in Mekele, Ethiopia, CEC finally chose ZOZEN boiler as the boiler supplier for this project based on the investigation on the domestic boiler market. This time, CEC purchased 3 sets of SZL series coal-fired chain grate water tube steam boiler form ZOZEN Boiler who had completed the shipment recently.
