Dongwha was founded in 1948 as a wood-based manufacturer named Dongwha Enterprise Co., Ltd. It has established overseas production bases in Malaysia, Vietnam, Australia and Finland. Among which, the Finland plant produces wide range of different types of impregnated papers. The thermal oil heater is purchased to provide heat source for an RTO waste gas treatment system introduced by Dongwha Finland.
The heat supply station plays an important role in local area, it provides the heating for over 75% of local residents in winter. Therefore, the station puts forward strict requirements on the heating boiler.
The distributed energy system project built by the customer company provided electric energy and heat energy for the surrounding enterprises through the cogeneration unit of gas-steam combined cycle.
Hubei Grand Fuchi Pharmaceutical & Chemicals Co., Ltd. is a cross-industry enterprise in the comprehensive chemical area, with businesses in fine chemicals, agrochemicals and chemical pharmaceuticals. As is known to all, steam boilers provide necessary temperature conditions for many chemical production processes such as distillation, concentration, drying, and chemical reaction processes. Therefore, Grand Fuchi put forward higher requirements for the quality of steam boiler and the qualification of steam boiler manufacturer.
Yingkou Yunken Animal Husbandry Co., Ltd., founded in 2017, belongs to Yunken Group. The company plans to gradually develop the whole industry chain of chicken feeding, slaughtering, processing and delivery. During the chicken slaughtering and processing, chicken scalding and other processes need a large amount of steam for heating to ensure the normal procedure of chicken production and processing. Therefore, Yingkou Yunken ordered a set of DZL series biomass-fired tri-drum steam boiler from ZOZEN Boiler to further improve the production quality and efficiency and provide healthier, safer and more nutritious chicken products for customers.
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.
In the printing and dyeing industry, industrial boilers have always provided the important heat source support for the printing and dyeing, drying, slashing and other production processes. Jiangsu Zhongcheng Printing and Dyeing Co., Ltd., established in 2001, is mainly engaged in the printing and dyeing of various kinds of cotton and polyester fabrics. Its main products are cotton and linen fabrics, elastic fabrics, high count and high density fabrics. Facing the increasingly strict environmental protection standards, in order to reduce energy consumption and save costs, Zhongcheng Printing and Dyeing decided to upgrade the boiler system and introduce ZOZEN SZS series gas-fired steam boiler to pursue better economic and environmental benefits.
ZOZEN has been a leading industrial manufacturer after more than 30 years of development. In recent years, with the increasingly strict environmental protection policies, ZOZEN has intensified great efforts in the research and development of gas-fired boiler products and improving the environmental performance and overall thermal efficiency of boilers. As a star product of ZOZEN environment-friendly boiler, the WNS series gas-fired boiler adopts an advanced low NOx burner. In addition, ZOZEN optimizes the design of furnace size, volumetric heat load, and the flue gas flow rate of the convection area to ensure that the NOx emission is less than 30mg / Nm3. In terms of improving the thermal efficiency of the boiler, ZOZEN adopts threaded smoke tubes to enhance the heat transfer effect. Meanwhile, through the application of condensation technology, the sensible and latent heat in the high-temperature flue gas can be fully absorbed, which can increase the inlet temperature and improve the
