GEECO Air Preheater Company

To ensure air preheaters availability and efficiency improvements, during plant outage, equipment inspection and evaluation studies of the operating parameters is necessary.

Every air preheater is unique in design and operation environment. Efficiency improvement studies of a rotary air preheater consists typically of an expert site visit during shutdown, for the purpose of thorough inspection and gathering pertinent data, and a report, detailing inspection results and recommendations, potential performance improvement, and estimated cost of implementation.

Once the plant is convinced of the improvements, effort should be taken for the implementation of the accepted suggestions, in the immediate available opportunity. Experience shows that in air preheaters, the improvements leads to a short pay back period. Hence it is worth to implement the improvements.
