Established in 2010, Guangning County Guangan Paper Co., Ltd. is an enterprise which is engaged in the waste paper recycling and manufacturing. In order to meet the market demands, Guangan Paper planned to invest a new expansion project with an output of 50,000 tons of gray paperboard. This project needed to introduce the new paperboard production equipment and a set of coal-fired boiler, and upgrade the existing pollution treatment facility at the same time. By virtue of high efficiency and good environmental protection performance, ZOZEN SZL series coal-fired steam boiler successfully won the favor of Guangan Paper to provide the stable and reliable steam supply for its dewatering, forming, drying and other processes.
Established in 1997, Baheer Group is a large-scale enterprise specialized in the production, packaging and printing of corrugated paper. With the increasingly larger production scale, the company's original heating equipment could not meet the steam demands of corrugated paper production and printing lines. In order to ensure the product quality and further improve the production efficiency, Baheer Group decided to introduce a set of high-efficiency and eco-friendly coal-fired steam boiler. After investigating and comparing the qualifications of many industrial boiler manufacturers in the world, Baheer Group finally purchased a set of SZL series coal-fired steam boiler from ZOZEN Boiler and set high requirements for the boiler's environmental protection performance.
Jilin Longyuan Fertilizer Co., Ltd., founded in 2004, is one of the subsidiaries of Longyuan Group. At present, the company has two ammoniation-granulation compound fertilizer production lines with a total annual output of 500,000 tons, a blended fertilizer production line with an annual output of 300,000 tons, and a potash fertilizer production line with an annual output of 100,000 tons. These high-capacity production lines placed high requirements on the steam quantity and quality of the boiler equipment and also posed a huge challenge to the boiler operating costs, especially the fuel costs. According to the actual demands, ZOZEN customized a set of SZL series coal-fired chain grate steam boiler for Longyuan Fertilizer. This series of boiler has sufficient output, high combustion efficiency and wide fuel adaptability, which can fully meet the needs of Longyuan Fertilizer.
ZOZEN SZL series gas-fired boilers with excellent quality and outstanding performance has become the heat source equipment of many enterprises of the paper industry. This series of boiler adopts D-type arrangement and water tube structure. The large-volume combustion chamber has good air proof and ensures complete combustion. Meanwhile, good quality alumina silicate fiber and fire clay insulation material are used to control the boiler body temperature below 45℃, and greatly heat loss is reduced. Energy-saving devices are equipped at the end of the boiler to increase the thermal efficiency to above 98%. In addition, SZL series gas-fired boilers are easy to operate. Advanced PLC intelligent control systems with various protection functions such as automatic water supply, program ignition, over-temperature control and over-pressure control can reduce costs for enterprises.
