Project Description

The objective of this project is to conduct an engineering study as a prelude to a field demonstration of how low-grade waste heat can be used to reduce water usage rates and improve system efficiency in a coal-fired power plant. A commercial system combining low-grade heat-recovery technologies and end uses to cost-effectively improve efficiency and reduce water consumption is yet to be developed. The project team will identify combinations of heat-recovery/use technologies that match up well for heat and temperature profiles, enabling identification of near-term opportunities for utilities to use waste heat; quantify the value of potential improvements in heat-recovery technologies with respect to the cost of the technology, potential increased benefits by widening availability of heat-uses that can be coupled with them, and potential water savings in terms of amount of water per unit of power produced; and recommend a combined process to be field tested at a Southern Company plant.

Project Benefits

This project may lead to a developmental breakthrough in water management for coal-fired power plants. The technologies developed, paired with the economic justification, may result in a pilot-scale field demonstration at a full-scale power plant. Interactions with the utility industry and its research and engineering partners will enable technology vendors to gain better understanding of coal power generators’ requirements for operation; while utilities will gain a better understanding of the near-term opportunities for viable heat-recovery/use technologies.
