6 FAQs about [Grate cooler middle roller breaking wind temperature]

Does grate cooler affect clinker cooling and waste heat recovery?

As an important process during the cement production, grate cooler plays significance roles on clinker cooling and waste heat recovery. In this paper, we measured experimentally the heat balance of the grate cooler, which provided initial operating parameters for optimization.

How does a grate cooler work?

The grate cooler is one of the most important devices for cement production and heat recovery, as it cools the clinker rapidly and recovers the exhaust air. The working process is as follows: high-temperature clinker from the rotary kiln falls into the grate cooler and continually moves forward carried by the grate plates.

What are the contents of the grate cooler experiment?

There are two mass transfers inside the grate cooler: clinker flow and air flow. Therefore, the contents of the experiment included the temperatures of the clinker and cooling air, and the mass flow rates of the clinker and cooling air. The production of the cement plant keeps unchanged during the experiment process.

What is the thermal efficiency of grate cooler?

Differences between the thermal efficiencies of grate cooler with different amounts of air chambers is no more than 2%. The highest thermal efficiency of grate cooler is 91.88% for system with 6 air chambers and the lowest is 89.99% for 11 air chambers. Fig. 9 Heat efficiencies of different amounts of air chambers.

What is the Heat Transfer Mode in a grate cooler?

In the latter half of the grate cooler, especially the third grate plate, the main heat transfer mode is the internal thermal conduction of the clinker particles, which is less influenced by the flow rate. This is in accordance with the cooling air distribution described in Section 2.2.

What is a grate cooler in a cement plant?

The grate cooler of the third generation is the most common one in cement plants. It is equipped with resistance grate and aeration beam and usually includes several air chambers. The cooling air flows through the moving clinker vertically as shown in .
