Heat transfer and pressure drop of new and eroded regenerative air preheater elements
Conventional fossil fuels will still play an important role in meeting the world's energy demands in the 21st century. In order to have a reliable and sufficient source of energy, it is necessary to conserve resources, which means: conserve resources in terms of investments and life span, and conserve resources in terms of higher efficiencies (thermal and hydraulic). In the power generation industry, research must strive to reduce heat losses, reduce maintenance costs, increase the life expectancy of plant equipment and ensure compliance with current environmental regulations. In coal fired power stations, the regenerative air preheater plays an important role in the performance of the plant. Thermal performance characteristics, erosion, corrosion and blockage can be responsible for poor performance. In the present study the thermal and hydraulic performance of different heating plates as used in regenerative air preheaters is investigated. In both the uneroded and the eroded state, two different commonly used profile designs are tested. After presenting the results for new packs, results for packs which are eroded to different stages of mass loss, are presented.
