Design of High Draught Brick Kilns with Zig-Zag Setting

Recently, As per MoEF Gazette notification dated 22.2.2022, it is necessary for all brick kilns to adopt high-draught zigzag brick kilns technology by Dec. 2023 for complying with emission standards of 250 mg/Nm³ and save of environment.

High Draught  Brick Kilns

In zigzag kilns, green bricks are arranged in a way that forces hot air to travel in a zigzag path. The length of the zigzag air path is about three times that of a straight-line air path, and this improves the heat transfer from the flue gases to the bricks, making the entire operation more efficient.
