Kiln Types. There are many styles of kilns, but the majority of them are Bull's Trench kilns. Kilns are often seasonally operated from November to June or July, taking a break from operating in the rainy season. Seventy percent of kilns currently in operation are Bull's Trench. Bull's trench kilns are in continuous use.

The Bull's Trench Kiln is widely used, especially in countries like India, due to its simplicity and cost-effectiveness. Structure and Layout: This kiln is typically oval-shaped and built in a trench, which can be fully underground or partly above ground. The trench is about 2 meters deep, lined with outer and inner walls constructed of bricks.

A: In this brief, a brick kiln A facility used for the production of bricks through a process of firing clay or other raw materials. Kilns are large, oven-like structures where bricks are fired at high temperatures to harden them. Brick kilns can vary in design and technology, but they generally consist of a firing chamber, where the bricks are stacked and heated, and a chimney …

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 ...
