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.
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.
In recent years, the state has paid increasing attention to environmental protection and launched the "coal to gas" policy. To actively respond to the policy and reduce the pollution of heating supply, Xincheng Heating Station upgraded the boiler equipment timely by introducing 2 sets of ZOZEN's SZS series gas-fired hot water boiler. This kind of boiler is featured with safety, high efficiency, energy saving and environmental protection, which provides solid guarantee for the central heating of residents.
ZOZEN Boiler launched the oil-fired/gas-fired skid-mounted steam boiler in order to meet the demands from overseas market. The so-called skid-mounted boiler is to place all the boiler parts such as boiler proper, economizer, burner, valve & instrument, controlling cabinet, water treatment, economizer circulating pump, raw water pressure pump and so on together on one or two skid-mounted blocks to form a boiler system which can move orderly as a unit.
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.
We were very satisfied with the ZOZEN gas-fired thermal oil heater which fully met the actual requirements of our production lines. In addition, the automatic control system was easy to operate, which greatly reduced the operation costs and improved the economics benefits for us.
This time, Jilin Deda purchased a branch of ZOZEN WNS series gas-fired boilers for demands of meat production and workers' heat supply. This type of gas-fired steam boilers adopts horizontal internal combustion wetback structure with novel design and rational structure. The burner flame is burning in large-diameter corrugated furnace in slight positive vacuum condition. It combined with high-efficient threaded smoke tubes and scientific furnace heat preservation design that can effectively improve thermal efficiency to more than 98%, which is superior to the national Level 1 energy efficiency standard and can realize the expected energy-saving goal of Jilin Deda. Besides, the advanced automatic control system can realize automatic start-stop, load adjustment, water supply and other operations according to the demands of users. With features of easy operation and low failure rate, the control system is both safe and reliable.
