First successful firing of bricks in vertical shaft brick kiln

First successful firing of bricks in vertical shaft brick kiln A few decades ago in China a new type of continuous kiln was invented. While the traditional continuous Vertical Shaft Brick Kiln is an energy efficient technology used for fired clay brick production. The technology was originally developed in China.

The flue gases leaving the firing zone exchange heat with dry bricks loaded, thereby pre-heating them. The flue gases finally enter the chimney through the flue duct at a temperature of 60 o C toBy adopting clearner brick manufacturing, 365.5 million tons (21.8%) of GHG emissions reduction can be achieved.

Firing shaft is very well insulated on all four sides, minimizing heat loss. Output: Each batch of bricks is made up of four layers, making a total of 320 bricks per batch. Many of these kilns put out 10,000-15,000 bricks per day (this figure may refer to a 2-shaft kiln).Vertical Shaft Brick Kiln Open Source Ecology

green bricks in the upper portion of the shaft, before exiting from the kiln through a shaft or a chimney (Refer Figure 2). The brick setting in the kiln is kept on support bars at the bottom of the shaft. The unloading of bricks is done from the bottom of the shaft, using a trolley. The trolley is lifted (using single screw mechanism)With the double smaller shafted kiln the shafts are loaded and unloaded alternately with 188 bricks in each batch, 12 batches per shaft, making a total firing capacity of 4512 bricks every 12 hrs. Ideally a batch of bricks is unloaded every 45 minutes to 1 hour, but the usual practice is to unload and load 3 or 4 batches at a time.Fastonline The Vertical Shaft Brick Kiln PDF Brick
