Zig zag technology— stacking the bricks in a zig zag pattern instead of straight line— converts the brick kilns by better insulating the walls and the floors. This method changes the way coal is loaded to redirect the air flow, which leads to better, more efficient fuel combustion and increases energy efficiency.
