Air Pollution due to Lime and Brick-Kilns | Environmental Engineering
In this article we will discuss about the occurrence of air pollution due to lime and brick kilns. Lime-Kilns: Quick lime manufacture involves calcination of lime stone at temperatures exceeding 900°C. Calcination is an endothermic process and the required heat energy is supplied usually by firing coal along with the lime stone. There are heaped and rectangular trenched kilns commonly-known [...]
