ZIG ZAG CHIMNEY BHATTA

Zig-zag chimney Bhatta offers a 15-20% reduction in Specific Energy Consumption (SEC) and up to 75% reduction in SPM emissions over FC-BTK. A higher percentage of Class I bricks are produced as compared to FC-BTK (80-85% Class I bricks as compared to 55-60% in FC-BTK).

There is an option for easy retrofit of FC-BTK to natural draught Zig-zag kiln. Savings from reduced fuel consumption and an increase in revenue due to a higher percentage of Class I bricks.

The capital cost of retrofitting of existing FC-BTKs ranges from INR 10-25 lakhs and pays back in 3 months-2 years. However, for new construction, the capital cost ranges from INR 35-45 lakhs natural draught kiln and INR 40-45 lakh for a high draught kiln.

The payback period for the new construction of the Zig-zag chimney Bhatta is 2-3 years. Zig-zag Bhatta required skilled manpower for its operation. However, the same workforce working in FC-BTK can be easily trained for operating Zig-zag kilns. 4 persons are required for firing at a 6-hour shift.

Advantage of Zig Zag Chimney Bhatta

1- zig-zag kiln reduces 20-25% Specific Energy Consumption.

2-zig zag kiln reduction up to 75% in SPM emissions over FC-BTK.

3-Increase the percentage of the class 1st bricks.

4-zig zag kiln produces 85-90%, first-class bricks.

  • The use of the down or cross draught system, with the fuel being burnt at regular intervals amongst the bricks, provides an even firing throughout the kiln.
  • The firing is controllable by the use of the dampers and careful stoking.
  • This is necessary when burning biomass fuels that have a higher mass and lower calorific value than other fuels, like coal or coke.
  • their use of waste heat the bricks Efficiency figures for Hoffmann kilns using coal as a fuel, in England and China and ranging from 1,800 at best to 2,350 kJ per kg fired brick at worst.
  • They have the capacity to fire very large quantities of bricks evenly and with minimal wastage.

4- High Draught Kiln technologies that are more energy-efficient and cause lesser pollution.One such technology named fixed chimney Zig – Zag kiln. The Zig-Zag kiln or the High Draught kiln is similar to firing technologies with essential variations in brick setting patterns where the kiln basic structure remains the same. The principle followed in this family of high draught kiln types is to prolong the travel path of the fire. This high thermal efficiency of the kiln reduces fuel consumption by 25%.

The earliest type of this technology was termed as Zig-Zag kiln and high draught kiln developed in the early 1900s.

Various reforms were also built which were relatively inexpensive variants adopted by small brick manufacturers. The design of this type of kiln ensures continuous operation of the kiln.

HYBRID HOFFMANN BHATTA

BHATTA CONSTRUCTION COMPANY

zig-zag Bhatta company is a national Bhatta construction,

which takes the form of two parallel tunnels built side by side, connected by curved tunnels at either end.

With such an arrangement.

Sixteen chambers are about the minimum for effective working; twenty-two chambers are preferable.

Although the burning time is only about three days or four days the bricks are in the kiln.

kiln for about ten days to allow for raising the temperature and,

after burning, subsequent lowering of the temperature before unloading the chambers. or

The Hybrid Hoffman kiln is no longer in use in India.

With such an arrangement. Sixteen chambers are about the minimum for effective working; twenty-two chambers are preferable.

the burning time is only about three days and bricks are in the kiln for about ten days to allow raising the temperature and after burning, subsequent lowering of the temperature.

Hoffmann kiln was superseded because it had such a large heat absorbing mass and

and the tapering firing chambers were small and unnecessarily complicated to load.

the very large damper between chambers was cumbersome and awkward to operate.

BHATTA CONSTRUCTION CHIMNEY

the above picture has shown the square chimney of zig-zag Bhatta.

Two firing zones running simultaneously are possible on the larger kilns. and in principle,

so they do not differ from the Hoffmann Kiln,

but with a high rate of fire travel, assisted by a strong fan draught system,

air passed through the id fan in high draught kiln process or zig-zag kiln process air passed through the chimney.

Advantages of Hoffmann Bhatta:

  • their use of waste heat the bricks Efficiency figures for Hoffmann kilns using coal as a fuel, in England and China and ranging from 1,800 at best to 2,350 kJ per kg fired brick at worst.
