The problem that how to use coal ash effectively in steam power plant has been common concerned and probed by designing

production

and scientific research personnel. Making effectively use of powder-coal ash can save investment and reduce production cost as well as protecting environment and usefully to society. The article on the basis of practice experience of Hua-Chong coal ash engineering in AnHui TongLing power plant

which designed and constructed by Hunan Company of electric power engineering overall con-traction

present design methcd of application of patent technique possessed by Hunan academy of electric power design. It sunmarizes construction measures ahd experience. For the problem existed in construction was analysised. It can afford people reference for similar engineering in designing

construction and management etc.
