and University of Illinois – examined the energy, environmental and financial performance and brick maker input for five main brick firing technologies during 2011: • Fixed Chimney Bull's Trench Kiln (FCBTK - India). • Zig-zag Kiln (natural and forced draft - India). • Vertical Shaft Brick Kiln (VSBK – India and Vietnam).
Fixed Chimney Bull's Trench Kiln (FCBTK) technology is the most widely used brick firing technology in South Asian countries. It is a continuous, moving fire kiln in which the fire is always burning and moving forward in the direction of air flow due to the draught provided by a chimney. The bricks are being. *Numbers are

Bull's Trench Kiln (BTK) was invented in England in 1887 by W.E. Bulls. He designed an arch-less version of Hoffman kiln, now called BTK. It is circular or elliptical in shape. Bricks to be fired are arranged in a trench and tall movable metal chimneys are placed on the brick setting. They are moved as the firing progresses.

Disadvantages. • More fuel efficiency compared to periodic kilns. – 2.5-2.8 MJ.kg. • Low initial investment. • High capacity. • Demands good organization of the brick production,. • Production cannot easily be adjusted to
The first kiln had a circular, arched tunnel surrounding the chimney. This reduced the fuel consumption by more than 50% compared to the periodic kilns. Thirty years later, a British engineer, W. Bull, designed an archless version of the Hoffmann kiln, which is now called a Bull' s trench kiln. It is widely used in Pakistan, India
