The commercial operation and performance test of the first 480t/h ultra-high pressure reheat circulating fluidized bed boiler showed that the product has simple structure and convenient control. The technical performance of this product is comparable to the international advanced level, especially the overall innovation in accordance with China's national conditions, so the rapid application of promotion. Last year, Wuxi Huaguang Boiler Co., Ltd. sold 20 of the products, achieving sales value of more than 1.5 billion yuan, and recently two other users put into use.
China's coal types are variable, the proportion of raw coal directly burned is large, and the contradiction between coal burning and environmental protection is very prominent, and circulating fluidized bed boilers are recognized as the preferred environmentally friendly products. Most of China's thermal power plants are equipped with pulverized coal furnaces with a capacity of 100MW and above. The pulverized coal boilers use tail desulfurization technology for high flue gas desulfurization costs, which is difficult to promote on boilers below 300MW, but can be passed through circulating fluidized bed combustion. Add limestone for flue gas desulfurization to significantly reduce harmful emissions. Among the hundreds of pulverized coal fired ones that were put into operation in the 1960s and 1970s, some of them need to be rebuilt each year, and there are quite a few new or expanded thermal power plants. Experts generally believe that with the upgrade of environmental protection heat, circulating fluidized bed is one of the most practical and feasible high-efficiency and low-pollution coal-fired equipment, with good promotion, development and application prospects.
In the process of development, the company reasonably borrowed the “outside brain†and cooperated with the Institute of Engineering Thermophysics of the Chinese Academy of Sciences to carry out a large number of domestic technological innovations in the 480t/h level, including: the first use of the volute import form Adiabatic cyclone separator; for the first time in the anti-wear structure of the four-sided water-cooled wall at the bottom of the furnace, a vertical let-off pipe structure, a large-diameter embedded counter-current cylindrical hood and a horizontal cold-distributing wind plate are used; for the first time, a large-diameter, high-flow secondary air vent is used. Design; for the first time, a special coal-dropping tube is used to feed coal, and no coal-fired fan is required; for the first time, the bottom of the furnace is used for direct slagging and the drum is cooled.
Technological innovation is difficult, and it is more valuable to have independent intellectual property rights. Through cooperation with the Chinese Academy of Sciences, Wuxi Huaguang Boiler Co., Ltd. not only keeps its technology up to the level of international development, but also takes the initiative in research and development. Some of the technological innovations of this project have obtained national patents.
After the project is implemented, the company can supply 480t/h high-temperature and high-pressure and ultra-high-pressure reheating large-scale circulating fluidized bed boilers, which will create a new situation for the localization of large-scale fluidized bed boilers in China, and at the same time create greater The capacity of the high-parameter circulating fluidized bed boiler provides experience to fill the gaps in this area in China and save the country a lot of foreign exchange. On the other hand, the product will replace many small boilers with low efficiency, high energy consumption and high pollution. Once the scale effect is formed, the operation efficiency will be improved, energy consumption will be reduced, emissions will be reduced, and ash can be comprehensively utilized. The benefits will be very significant, and the promotion and application is of great significance.

Huaguang Boiler "Bear the Brain" to tackle new products in China
The 480t/h ultra-high pressure reheat circulating fluidized bed boiler produced by Wuxi Huaguang Boiler Co., Ltd. has passed the expert appraisal in Beijing. The product adopts the clean coal-fired technology of the Institute of Engineering Thermophysics of the Chinese Academy of Sciences. It was equipped with the 150MW steam turbine generator set of Inner Mongolia Huadian Wuda Thermal Power Co., Ltd. in March last year. It completed the boiler performance and environmental protection test in September. It is the first domestically produced enterprise with independent intellectual property rights. Large-capacity high-parameter circulating fluidized bed boiler.
