AQC waste heat boiler: the kiln head boiler is vertical, natural circulation. Because the dust in the exhaust gas of the cooler is not strong, so there is no ash cleaning device. At the same time, the heat exchanger tube using spiral finned tube, greatly increasing the heat transfer area, making the boiler volume decreased significantly, reducing investment costs. At the same time, in the AQC waste heat boiler front end set up a high-efficiency settling chamber, greatly reducing the exhaust gas on the AQC waste heat boiler wear and tear.

Vertical waste heat boiler completely solved the horizontal waste heat boiler air leakage and the actual distribution of the temperature field in the furnace and the boiler design is completely different from the assumed temperature, can greatly improve the boiler steam production; grate cooler or vertical waste heat boiler discharged waste heat about 200 ℃ can be fully recovered and used to generate electricity. This can make tons of clinker waste heat power generation in the clinker under the premise of unchanged heat consumption increased to more than 195 kWh, so that the cement kiln comprehensive energy consumption to reach the same size of the precalciner kiln level of energy consumption, while the economic benefits are much higher than the precalciner kiln.
