Thermal Power Aggregates
The coal from coal mines is supplied to the thermal power plants for electricity production which contains both coal and stones. The material which contains less percentage of coal content in them is rejected. This waste aggregate is utilised as a replacement of natural aggregate in Granular Sub-Base (GSB) and bituminous layers in road construction. BTL EPC Ltd. manufactures customised and state of the art air pre-heaters that are extensively used in this sector.
