5-CBRI High Draught Brick Kiln Technology

250 billion bricks per year. About 70% production of bricks in India depends on conventional Fixed Chimney Bull's Trench Kiln technology (FCBTK), consuming approximately 35 million metric tons of low-grade coal. High draught brick kiln is a continuous, cross draught, moving fire kiln in which the air flows in a zig-zag path.

Modernizing Artisanal Brick Kilns: A Global Need

An early design improvement came during the mid-1800s, when the British engineer William Bull invented the Bull's trench kiln (BTK) that bears his name. Bull, noticing that kilns' appetite for fuel was denuding the Indian landscape of trees, designed the BTK to take advantage of waste heat from newly fired bricks and fuel combustion. 13 The ...
