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.
Wengfu Zijin Chemical Co., Ltd. established a project on the phosphorus chemical engineering, through transfer the local by-product of metal smelting to product and refine the acid and ammonium phosphate products, then recycle the phosphogypsum. It is necessary for the boiler to provide a large amount of continuous heat for the whole production line, and to dry and calcine phosphogypsum.
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.
It is an important strategic deployment put forward by the central government to promote clean heating in winter in northern China. Recently, a clean energy central heating project with a total investment of 20 million dollars has been built in Hebei province, China. The project rectifies the old equipment and plans to use 2 sets of gas-fired hot water boilers to provide central heating for local residents. The requirements of the boilers are as follows:
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.
The customer project is located in Hainan Province with a total investment of 28 million US dollars in the first phase. After the project is completed, the biomass resources of Yangpu and surrounding cities and counties will be fully used to realize the resource utilization of renewable energy, and the heating steam will be provided for the enterprises in and around the development zone to meet the production needs of relevant enterprises. As the gas-fired boiler supplier of this project, ZOZEN boiler provided a set of gas-fired superheated steam condensing boiler with capacity of 50 tph.
Well Baal Food (Kunshan) Co., Ltd. is a comprehensive manufacturer specializing in the production of retort pouch. Sterilization is a necessary process for food production. Industrial boilers provide the high-temperature steam to sterilize the raw material of food. Therefore, the customer ordered a set of WNS series gas-fired steam boiler system from ZOZEN Boiler.
Shenmu Shengbang Chemical Co., Ltd. was established in 2010, mainly producing and selling semi-coke, coal tar and other products. As an important piece of equipment providing heat resources on the production line, the steam boiler provides necessary high temperature conditions for the drying and carbonization of semi-coke.
