As we all know ,kiln is a essential part for a brick factory.There are may types of kiln ,like hoffman kiln ,tunnel kiln...etc .
The Hoffmann kiln is a series of batch process kilns. Hoffmann kilns are the most common kiln used in production of bricks and some other ceramic products.

Advantages of Hoffmann kilns

• They are fuel efficient because of the direct stoking into the bricks and their use of waste heat to dry and preheat the green
   bricks before firing. Efficiency figures for Hoffmann kilns using coal as a fuel, in England and China, range from 1,800
   at best to 2,350 kJ per kg fired brick at worst.

• They have the capacity to fire very large quantities of bricks evenly and with minimal wastage.

• The use of the down or cross draught system, with the fuel being burnt at regular intervals amongst the bricks, provides an
   even firing throughout the kiln.

• The firing is controllable by the use of the dampers and careful stoking. A variety of biomass fuels can be used successfully,
   for example, sawdust and wood processing waste, rice and coffee husk. These fuels can be added through the roof of the kiln
   with the use of mechanised fuel charging hoppers that run on compressed air or electricity. This is necessary when burning
   the biomas fuels that have a higher mass and lower calorific value than other fuels, like coal or coke.
