淮阴发电厂是50年代建成的老厂。三十多年中,随着电力工业的发展,在240亩土地上,堆起了7米高的3座灰山,风吹灰扬,成为淮阴市的“灰风口”。压力变成了动力,他们在“吃灰”上大做文章,揭开了综合利用“三部曲”序幕。第一步,把粉煤灰用于筑路和烧砖。1986年在淮宁公路施工中,一年多“吃灰”15万吨。与此同时,周围众多砖瓦厂将粉煤灰作为掺和料,也尝到了“甜头”,仅兴化市砖瓦厂一年就利用粉煤灰1万余吨。 Huaiyin Power Plant is an old factory built in the 1950s. In the past three decades, with the development of the electric power industry, three gray hills with a height of 7 meters have been piled up on 240 acres of land. The wind has turned gray and has become the “gray tuyere” in Huaiyin City. Pressure became a driving force. They made a fuss about “eating ash” and opened the prelude to the comprehensive use of the “trilogy”. In the first step, fly ash is used for road building and firing. In the construction of Huaining Highway in 1986, more than 150,000 tons of “ash was eaten” for more than a year. At the same time, many brick and tile plants around the city used fly ash as admixture, and they also tasted “sweetness”. Only Xinghua brick and tile factory used more than 10,000 tons of fly ash a year.
