Different types of brick kilns 2

In intermittent kilns, bricks are fired in batches. Generally, bricks and fuel are stacked in layers and the entire batch is fired at once ; the fire is allowed to die down and the bricks allowed to cool after they have been fired. The kiln must be emptied, relled and a new  restarted for each load of bricks. In intermittent kilns, most of the heat contained in the hot flue gases, in the fired bricks and in the kiln structure is thus lost. Clamp, scove, scotch and downdraught kilns are examples of intermittent kilns. Such kilns are still widely used in several countries in Asia, Africa, and South and Central America as well as in some parts of England and Belgium.
In a continuous kiln, on the other hand, the fire is always burning and bricks are being warmed, fired and cooled simultaneously in different parts of the kiln. The heat in the flue gases is utilised for heating and drying green bricks, and the heat in the fired bricks is used for preheating air for combustion. Due to the incorporation of heat recovery features, continuous kilns are more energy-efficient. Such kilns can be further sub-divided into two categories : moving-?re kilns and moving-ware kilns.In a moving fire kiln, the fire moves progressively around a closed kiln circuit  while the bricks remain stationary.
