carbonaceous backfill (Carbonaceous backfill also known as Coke Breeze is calcined carbon. It is used to surround impressed current anodes to improve the efficiency of the anodes. The backfill increases the effective size of the anode giving a lower resistance to earth and is consumed at a predictable rate from the current discharge. – КМА Alexander Demidov); coke breeze (Coke breeze (metallurgy) is the undersized screenings of coke (usually less than 10 mm). During coke production the screening operation is where pieces and dust too small for steel making are removed. Coke breeze is either reused on site (e.g. in the sinter plant) or sold off site as a by-product. Coke breeze can used as the basis of a building material (e.g. "breeze blocks" or "cinder blocks") or used as an industrial boiler fuel. wiki.answers.com Alexander Demidov) |
