Operating ratio and cost of coal power generation ICSC

Nov 16, 2016  The more frequent cycling of coal-fired power plants can cause thermal and pressure stresses. Over time, these can result in premature or unplanned component failure and increased maintenance. Repeated starting up and shutting down of a unit, or operating at part load, can also increase emissions compared to non-cyclic operation.
