Th ere are more than 100,000 brick kilns in the country producing bricks. Fixed Chimney Bull's Trench Kiln (FCBTK) is the main brick kiln technology accounting for 70% of the production. Brick kilns consume about 35 million tonnes (MT) of coal a year, making them the second largest industrial consumer of coal aft er the steel industry.

The shaft is square or rectangular in section - usually 1 meter in width and 1m, 1.5 m, l.gm and 2 m in length Its inside surface is a brick wall sometimes lined with one layer of firebricks in the hot firing zone. The gap between the shaft wall and the outer kiln wall is filled with insulating materials such as clay or rice husk mixed with clay.
