Oct 01 1999nbsp018332However plants usually dont have expensive flow elements and datalogging software particularly if the compressed air system is a relatively minor utility The second method provides a reasonably accurate measurement of the compressed air load of a system without having to invest in fixed equipment but it still means paying a specialist
During cement production process part of the fuel can be burned in preheater so it is necessary to supply additional air tertiary air which should be taken from the clinker cooler 1
Subsequent calculation was based on the principle of input clinker cooling air fuel water injection and output clinker temperature secondary and tertiary air excess air and cooler radiation of clinker from the grate cooler 311 cooler input the cooler clinker input is considered as 1 kg which is taken as the basis for the mass

Compressed air is one of the most expensive sources of energy in a plant the overall efficiency of a typical compressed air system can be as low as 10 to 15 for example to operate a 1hp air motor at 100 psig approximately 7 to 8 hp of electrical power is supplied to the air compressor
The kiln is a large furnace that is fueled by coal oil gas coke andor various waste materials the product called clinker from the kiln is cooled ground and then mixed with a small amount of gypsum to produce portland cement the main source of air toxics emissions from a portland cement plant
