ZG has provide many Large-scale CFB boiler for companies. Not only large-scale, but also they are very energy-saving. These CFB boiler takes the principle of stationary design and circulating fluidized bed map as the guide, the theory of material balance and the theory of particle fuel combustion and a more substantial reduction in the total bed stock, thus form the flow pattern based on the re-structure of energy- efficient CFB boiler technology. After successful developing of 130t/h~150t/h CFB by ZG in 2001, the CFB technology begins to advance rapidly. It steps from intermediate temperature and pressure, sub-high temperature and pressure to high temperature and pressure, and super-high pressure reheating unit, which covers all series of product with different capacity such as 35t/h, 75t/h, 130t/h, 220t/h, and 440t/h. It can apply to different kinds of coal, such as gangue, anthracite, bituminous, petroleum coke. At the same time, ZG launched boiler island Turn-key business with a significant breakthrough through four boiler island contracts in Thailand and Vietnam, among which three of them are the most difficult units for coal and bio-mass fuel mixture combustion, fulfilled the combined combustion of paper pulp, waste residue and tree bark. In China, ZG CFB boiler has many successful cases. As the following:
2x410t/h CFB boiler installation sit of Hong Yu Co.Ltd
3x75t/h CFB boiler for Xuchang Weiteng Thermoelectricity Co.Ltd
116MW CFB boiler for Zhengzhou Heating Company
2x75t/h CFB boiler for Pingdingshan Salt Industry Co. Ltd.
