  • Vertical Shaft Brick Kiln buildipedia

    The inner side of the firing shaft is lined with refractory bricks in order to provide maximum heat resistance and ensure exact vertical for trouble free operation. The gap between the refractory shaft wall and outer kiln wall is filled with insulating materials. The firing shafts are open at the top and the bottom.

  • Vertical Shaft Brick Kiln Open Source Ecology

    This operating principle is similar to that of a vertical shaft lime kiln. Cold air entering at the bottom cools down the descending (fired) bricks, is then used for firing, then warms up the still-cold bricks on top of the stack. Bricks are loaded at the top and removed at ground level in a continuous process (see animation below for details).

    Many of these kilns put out 10,000-15,000 bricks per day (this figure may refer to a 2-shaft kiln). Quality is very high and brick wastage is very low when compared to other kilns, being only 2-5% in China. The firing process is completed in about 24-30h as the bricks move from top to bottom. One batch is removed at the bottom at a regular interval.
