Research and Application on Electric Precipitation Technology with Low-low Temperature

The electric precipitation technology with low-low temperature is one of the effective technologies in realizing energy saving and emission reduction in the coal-fired power plant. It can further extend the applicable scale of electric pre-cipitators, meet the requirement of new environmental standards, and can remove off the great mass of SO3 in flue gas. The technology shows the proof of engineering practices abroad, the helpful exploration and attempt in the country and the opera-tion achievement of 600MW generating set. The paper sums up the development and technical characteristic of the electric precipitation technology with low-low temperature, analyzes the research status of the technology, enumerates the cases of engineering application at home and abroad, probes into the core problem of the technology and countermeasures so as to provide the use for reference in the application and development of the electric precipitation technology with low-low temperature in the coal-fired power plant of the country.
