すものである。In the process of preparing FFI fired products such as cement clinker, an air quenching cooler (hereinafter referred to as AQO) is often used to cool down the fired products fired in a kiln and at an FC recommended temperature. . The air that cools the baked goods discharged from this person's QO has a slightly chilly temperature, but the heat contained in this air is normally released into the atmosphere without being effectively utilized. Therefore, in order to recover and effectively utilize this thermal energy released into the atmosphere, a more efficient QO as shown in Figure 1 was proposed. This AQ
, Oi is divided into Grade 2, which transfers the high-temperature fired product from the firing furnace to the rear, and the Proa 5, which supplies cooling air to the lower chambers, which are divided by Grade 2 and are divided into upper chamber 3 and lower chamber 4. ...and the air passage 6 which cools the high temperature fired product and takes out the heated air from the vicinity of the rear end 3 & of the upper ill chamber 3 and sends it back to the lower chamber 4. It is installed in the middle and consists of Kushu Todoroki Mk7 and residual heat boiler 8,
Collect heated air from rear end 3 & vicinity of upper chamber 3 I1 machine 7
The heat contained in the heated air is recovered and cooled by the residual heat boiler 28, and the cooled air is sent back to the lower lit chamber.
