e.g., Hoffmann kilns, high draft kilns, or vertical shaft brick kilns (CAIAsia 2008 World Bank 2010). A summary of various kiln technologies and comparison to inuse FCBTK is presented in Table1.Ofthe technologies listed in Table 1, FCBTK is the most common technology and only the vertical shaft technology is under pilot stage (World
friendly brick firing technology, i.e. through the Vertical Shaft Brick Kiln (VSBK) Technology. Generally, it is understood that the operation of a VSBK is a practical art, being mastered by the competent firemen through years of intense training. This is usually the case so for
In a shaft kiln, the limestone dolomite moves counter flow to hot gases in the shaft. This gives shaft kilns the lowest fuel consumption of any type of calciner. The shaft refers to a vertical vessel where the calcining takes place.
In a continuous kiln, on the other hand, the fire is always burning and bricks are being warmed, fired and cooled simultaneously in different parts of the kiln. Examples of such kilns include Bull''s trench kiln (BTK), Hoffmann, Zig zag kilns, Tunnel kiln and vertical shaft brick kiln (VSBK) (Heierli and Maithel, 2008). Majority of the kilns in
The Vertical Shaft Brick Kiln : a technology for the masses. Dr Soumen Maity [email protected] Shelter, along with food and clothing forms a basic need for all human beings. In India, with the rapid growth in population and infrastructure building, it is increasingly becoming difficult to balance between the demand and supply of construction materials.
When simplicity, lower capital investment and easy maintenance are the main issues, Urja vertical shaft kiln is the right kiln. Numerous fuels such as coke, coal, gas, oil, as well as other alternative fuels are combusted using different types of burner or charging systems.
Shaft kilns. The theoretical heat (the standard enthalpy) of reaction required to make highcalcium lime is around 3.15 MJ per kg of lime, so the batch kilns were only around 20% efficient.The key to development in efficiency was the invention of continuous kilns, avoiding the wasteful heatup and cooldown cycles of the batch kilns.
Vertical Shaft Brick kilm Energy Efficiency. By piloting and disseminating an energy efficient brick production technology using vertical shaft brick kilns, CO2 emissions can be reduced by more than 100 000 tons per year in South Africa.
Energy Efficient Brick Production: Vertical Shaft Brick Kilns Background and Context Brick production is a large and rapidly growing industry in many parts of Asia, especially Pakistan. This is courtesy the consistent growth in the construction industry that boasted of an average growth rate of
Langkloof Bricks made history by introducing the first new energy efficient Vertical Shaft Brick Kiln (VSBK) in Africa. This clay brick factory, owned by the Blake family in Jeffreys Bay is on record for pioneering one of the most technologically advanced VSBK kilns in the world today. Source our Bricks at: co.za
Our standard linings for vertical shaft kilns consist of wearresistant hotface linings and thermally efficient backup linings. This combination provides lime producers with an economical and tough refractory lining that can withstand the thermal and mechanical challenges present in a vertical shaft kiln.
methods. In comparison to the clamp kilns, the VSBK technology is an energy efficient way of firing clay bricks and is particularly suited to the needs of developing countries. The Vertical Shaft Brick Kiln (VSBK) Project is part of the SDC Climate Change Mitigation Programme in South Africa. The programme focuses on energy efficiency in the
Apart from BTKs, there is also clamp, Hoffman and Vertical Shaft Brick Kilns (VSBK) in Nepal. Government has promulgated the standards on Chimney Height and Emission for the brick industries since 2008. Table 1: Emission Standards and Chimney Height for Brick Kilns in Nepal.
Langkloof Bricks Langkloof Bricks made history by introducing the first new energy efficient Vertical Shaft Brick Kiln (VSBK) in Africa. This clay brick factory, owned by the Blake family in Jeffreys Bay is on record for pioneering one of the most technologically advanced VSBK kilns in the world today. This is as a result of the successful implementation of a Technology
Many of these kilns put out 10,00015,000 bricks per day (this figure may refer to a 2shaft kiln). Quality is very high and brick wastage is very low when compared to other kilns, being only 25% in China. The firing process is completed in about 2430h as the bricks move from top to bottom. One batch is removed at the bottom at a regular

Swiss Agency for Development and Cooperation Technical: Introduction of Vertical Shaft Brick Kiln (VSBK) Technology
vertical shaft brick kiln is a continuous, moving ware kiln in which bricks are fired in a vertical shaft of rectangular. cross section. The height of the shaft is around 6 – 8 m andnominal crosssection of the shaft 1.90 x 1.40 m. The kiln consi sts of banks of multiple shafts. The shafts are enveloped by an outer
The ecotechnologies of clay brick production developed by the EcoSur Networka had an impact world wide. In Malawi, southeast Africa, a young entrepreneur built a Vertical Shaft Brick Kiln (VSBK) based in the kilns built in Ecuador, South America.
Vertical Shaft Brick Kiln (VSBK) Afghanistan Under the mandate of SDC, Skat contributed to the introduction of energyefficient and environmentally friendly brick production technology to the Afghan brick
However, the vertical shaft technology could run round the year with general maintenance for 25 years against the centuriesold brick kilns that lasted as less as four to five years despite

Realising the challenges but also the great opportunities in the brick sector the Malawian enterprise EcoMatters decided to invest in a brick production plant and realised in collaboration with the Indian Society for Technology & Action for Rural Advancement (TARA) an EcoKiln in Lilongwe using the Vertical Shaft Brick Kiln technology.
for kilns with and without exhaust stacks and has been tested on bull''s trench, zigzag, clamp, vertical shaft, and tunnel kilns in South Asia and Vietnam. General guidelines for selecting measurement methods for brick kilns can be found in the report: Brick Kiln Measurement Guidelines: Black Carbon Emissions and Energy Performance .

The improved Vertical Shaft Brick Kiln (VSBK) that burns less coal and emits less smoke is being used in only eight brick factories in Nepal, including two in the Valley. Although work conditions are inhumane, the brick industry provides jobs to thousands of unskilled labourers.
The Vertical Shaft Brick Kiln ( VSBK ), developed in China, is the most energy efﬁcient kiln, despite it looking rather more like an old building and not at all like a hightech installation. It consumes only 110 grams of coal to produce one brick, rather than 250700 grams used in traditional clamp kilns.
