What are the reasons for air leakage in the lignite dryer

The feeding inlet and the inlet and outlet of the drum and pipeline connection of the lignite dryer are prone to air leakage. Severe air leakage can lead to increased fuel consumption and inability to raise the temperature of the hot air. If the air leakage phenomenon is not solved, on the one hand, it will waste more fuel and reduce the efficiency of the dryer. On the other hand, it reduces the exhaust temperature of the dryer, causing condensation inside the chimney pipeline, which is more likely to cause acidic corrosion and affect the pipeline's lifespan.

The following are the reasons for air leakage in the lignite dryer:

一、 Air leakage at the feeding end of the lignite dryer

1. The sealing device between the feeding end and the feeder during prolonged operation is severely worn and becomes larger.

2. The sealing device at the feeding end is severely worn during prolonged operation.

二、 Air leakage at the discharge end

1. The sealing of the discharge end is damaged after prolonged operation

2. Corrosion and air leakage of the dust collector
