[0013] A method for producing quicklime by using brick-making waste heat of the present invention, the first step is to stack the bricks on the kiln car, and the number of stacks for each kiln car depends on the size of the kiln car. The kiln car used in the existing large-scale tunnel kiln can be Stack adobe stacks of 3x4 quantities. The second step is to push the kiln car with the adobe stacked into the tunnel kiln. The first thing to enter is the moisture removal section. This section has a temperature of 80-100°C and after 8-10 hours, the hot air will dehydrate the adobe to about 3-5%. The load-bearing capacity of the adobe is greatly increased. The kiln car then enters the preheating section. The top of the tunnel kiln in this section is provided with feeding holes corresponding to the distance between the piles of bricks on the kiln car. At the same time, a mineral material conveying system is set up on the top of the tunnel kiln. 20cm of limestone is paved on the top o...
