Also during this test, measurements and data were gathered to perform a heat balance for the pyroprocessing system and to calculate the Specific Power Consumption of the following items; kiln feed transport, clinker cooler drives, fans and breaker, primary air fan, kiln …

Unfortunately, the more efficient (in specific fuel consumption) a kiln becomes, the higher tlre cooler exit losses will be. The heat-balance examples show this clearly where the inefficient wet-process kiln shows 3.3% cooler losses compared to the more efficient preheater kiln which shows 18.4% losses. Lower kiln radiation losses by:

75% of the heat transfer is a result of focused convective heat transfer between: 1. The air drawn into the kiln through the cooler and interior surfaces, 2. Conductive heat transfer between interior surfaces and the product internals. 25% of the heat transfer is a result of …
