Combustion calculations in Cement industry ( updated & complete )

 

 

Conversion of Gross Calorific value to net Calorific value

Gross calorific value (GCV) of a fuel is the heat evolved in its complete combustion under constant pressure at a temperature of 25C when all the water initially present as liquid in the fuel and that present in the combustion products are condensed to liquid state

Net calorific value (NCV) of a fuel is the heat evolved in its complete combustion under constant pressure at a temperature of 25 C when  the water in the system after combustion is taken as vapour.

Ultimate analysis

The ultimate analysis is useful to calculate the theoretical combustion air required and volume of combustion gases.

Proximate analysis

The proximate analysis involves quantitative determination of moisture, volatile matter, carbon and ash. This analysis is for quick preliminary appraisal of coal.

  1. how does the curve of kiln heating up during the following situation
    1-after the replace the bricks
    2- after the mechanic maintenance or any ordinary stops and the rotation the kiln during the heating process
