In September 19th, the blockage of dust generated during the operation of electric coal-fired boilers was a problem of high energy consumption and high pollution in thermal power plants in China. An acoustic soot blower independently developed and filled by China can solve this problem, so as to ensure the safe and normal operation of the desulfurization equipment of the generator set, and achieve greater energy conservation 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. The ash removal and energy saving problems of the pre-combustion device, tail flue, furnace, etc. effectively remove the fouling of the flue gas heat exchanger so that it is no longer blocked, thus ensuring the normal safe and economical operation of the desulfurization device of the boiler. 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 of our thermal power units 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.
