Adjustable high sound intensity sonic soot blower was successfully developed

Xinhua News Agency, Beijing, September 19 (Reporter Zheng Xiaoyu) The blockage of ash deposits generated during the operation of coal-fired boilers is a difficult problem of high energy consumption and high pollution in thermal power plants in China. An acoustic sootblower independently developed by China and filled in the blank can solve this problem, so as to ensure the safe and normal operation of the generator unit and achieve greater energy saving and emission reduction benefits. This achievement passed the appraisal of national-level energy science and technology achievements on the 18th.

An appraisal committee organized by the National Energy Administration and composed of academicians of the Chinese Academy of Engineering and experts in environmental protection, energy conservation, emission reduction, environmental acoustics, and other aspects believes that such an “adjustable high-frequency sound sonic soot blower” can solve the problem of empty coal-fired boilers in China. Precipitators, tail flue, furnace and other parts of the ash, energy conservation issues, effectively remove the flue gas heat exchanger fouling, so that it is no longer blocked, so as to ensure the normal safety and economic operation of the boiler off the device. The appraisal committee believes that this achievement has reached the international advanced level.

According to the researcher Nanjing Changrong Noise Control and Environmental Protection Engineering Company, a conventional 600,000-kilowatt thermal power generating unit installed on the tail flue will save 1% of coal and save about 9 million yuan per year for the power plant. Meta operating costs. If all the thermal power units in China are equipped with such equipment, the potential for coal saving will be around 20 million tons. According to reports, the technology can also be applied to metallurgy, petroleum and petrochemical, building materials and other fields.
