China Hoffman Kiln for Fire Brick Making Factory

1.The Hoffmann kiln is a so-called "continuous kiln" - it burns 24 hours a day, 7 days a week, 365 days a year (except when it goes down for maintenance).
2.This method was very time-consuming because it is essential to ensure that ceramic materials are not heated up and cooled down too fast.
3.This meant that the fire had to be increased very slowly and carefully, and that the baked bricks had to remain in the oven several days after the fire was extinguished.
4.During this whole period, the periodic oven could not be used to bake a new stack of bricks.Moreover, the structure itself had to be heated up every time, and during the firing process most heat was lost through the chimney or the roof, wasting large amounts of fuel.
