Energy performance of brick kilns
Specific fuel consumption, in terms of tons of fuel consumed for firing one lakh bricks
is the popular way of expressing performance brick kilns in India. The mode of
expressing performance in this manner may be of interest to brick manufacturers,
however, it is difficult to compare performance of brick kilns on this basis, because of:
i) the varying weight of fired bricks which may vary from about 2 kg to 3.75 kg in
India;
ii) the difference in quality and hence calorific values of various fuels used for
firing bricks.
Specific energy consumption or the energy consumed for firing one kg of fired
brick is a better way of comparing performance of brick kilns.
