Pre-Feasibility Report on a Brick Manufacturing Fuel Substitution CDM Project — October 2002 1. Project Description Brick Manufacturing in Bangladesh More than 95% of the bricks in Bangladesh are manufactured in cottage-type industries using an extremely crude technology known as the Bull's Trench Kiln (BTK). The kiln is
The most commonly practised technology is the Bull's Trench kiln with an average capacity of 20,000 bricks per day. The variation in fuel consumption is from 5.1 GJ/1000 to 3.2 GJ/1000, in different parts of the country depending on type of chimney, fuel type, soil type and firing practices.
Hoffman's kiln is an over the ground structure while Bull's Trench Kiln is an underground structure. Hoffman's kiln have a permanent roof while Bull's trench Kiln does not have so it former can be used in 12 months a year to manufacture bricks but later is stopped in the monsoon season. Hoffman's kiln is generally circular in plan and ...
Conventional brick kilns—Bull's Trench Kiln (BTK)—in Pakistan's Punjab province are a significant source of greenhouse gas emissions and harmful particulates which exacerbate climate change and deteriorate ambient air quality, respectively.
The bricks are being warmed, fired and cooled simultaneously in different parts of the kiln. It is a modified version of Bull's trench kiln introduced by a British engineer W. Bull in 18761 . Initially it had movable metal chimneys which were placed on the brick setting and were moved as the firing progressed.
For firing, Fixed Chimney Bull's Trench Kiln (FCBTK), a type of continuous kiln, is the main technology in use, accounting for about 70% of the total brick production in India (Figure 2). FCBTKs are mostly used in the Gangetic plains and in pockets all around the country (Figure 3). Intermittent kilns such as clamp kilns, which produce bricks ...

Current technologies for brick production such as clamps, downdraught kilns and Bull s trench kilns consume large quantities of fuel such as coal, firewood and other biomass. VSBK is the most efficient firing technology available, where the fire remains static and the product moves through the firing zone (vertical format of tunnel kilns).

The Board had also underlined its confusion regarding action to be taken against the other two types (clamps and moving chimney) as their legal status was unclear. NGT directed the Board to serve ...
Fixed Chimney Bull's Trench Kiln (FCBTKs) have been reported to have poor heat transfer characteristics and require higher fuel and consequently produces higher emissions. Cleaner technologies such as the Zig-Zag Kiln (ZZK) can potentially achieve greater energy efficiency due to optimized airflow and reduced heat loss ( Heierli and Maithel ...

The study found that the clay quarrying and brick making industry has expanded exponentially. The type of kilns has transitioned from artisanal style clamp kilns to small-scale Bull's Trench Kilns (BTK), and ultimately to Fixed Chimney Bull's Trench Kilns (FCBTK).
This process improves the overall quality of bricks and is safer for the health and wellbeing of the employees who work in the kiln. But let's be honest. Market reality is a consideration for any industry, as it is for the brick industry. Granted that using natural gas to fire bricks produces less pollutants, but what about the feasibility ...
commonly used in South Asia and are the most energy intensive. Bull's trench kilns are the primary kiln technology used by large-scale manufacturers. Vertical shaft brick kilns (VSBKs) are the most energy-efficient kiln technology but have not been widely adopted throughout South Asia. Emissions Profile

Bull's trench kiln (BTK) Bull's trench kiln (BTK) is essentially an elliptical-shaped dug-out area in an open field. The kiln is about 7 m long and 17 m wide and has two 10 m high movable chimneys. The bottom and the side-walls of the kiln are lined with bricks, with the top left open.
The vertical shaft brick kiln (VSBK) has become widespread in China and is slowly gaining a foothold in Pakistan. In India, Bangladesh and Pakistan, the relatively energy-efficient Bull's trench kilns are standard; although VSBKs are using 30 to 50 percent less …

The most common type of brick kiln in use there are Bull's Trench Kiln (BTK), based on a design developed by British engineer W. Bull in the late 1800s. The fired colour of bricks is significantly influenced by the chemical and mineral content of raw materials, the firing temperature and the atmosphere in the kiln. Get More
