Method to produce durable non-vitrified fly ash bricks and blocks

耐用且无需燃烧的煤灰砖块制造方法

Abstract

The invention relates to a durable coal dust brick, a block, an air brick and other construction product without burning. Through the special method of the invenion, the soot can be made into durable brick and other product, rather than heating the rough produces in the brickkiln, thereby reducing the required energy consumption and cost. The soot used to produce the brick and other construction products usually is processed as the solid castoff, thereby reducing the castoff generated in the coal power plant. Furthermore, using the soot products without burning (no sinter) can reduce the use of the sinter clay products which need to heat the product in the brickkiln by using the mineral fuels, thereby generating the air pollution and carbon dioxide, while the latter can cause the green house effect and global warming.
本发明涉及制造耐用且无需燃烧的煤灰砖块、石块、空心砖以及其他建筑产品。通过使用本发明中的特定方法,可将煤灰制成耐用砖块和其他产品,而不必在高温下加热砖窑内的毛坯产品,从而减少了传统粘土砖制造中所需的能耗与成本。用来制造砖块和其他建筑产品的煤灰,通常是作为固体废弃物来处理掉的,因而降低了燃煤发电厂所产生的废弃物。而且,往后采用这种无需燃烧(无烧结)的煤灰产品会减少烧结粘土产品的使用,这些粘土产品需要使用矿物燃料对砖窑内物品进行加热,从而产生空气污染和二氧化碳,而后者更会导致温室效应和全球变暖。
