Applications of the diesel coal combined cycle
Abstract
The proprietary process known as the Diesel Coal Combined Cycle (DCCC) is examined for its application to new cogeneration plants and independent power production facilities as well as repowering of existing plants. High-cycle thermal efficiency with a heat rate in the range of 9,000 Btu/kWh (HHV) can be achieved by combining prime-mover diesel engine generators that have inherently high efficiency with boilers, specially designed burners, and a conventional Rankine steam cycle. Plants using the DCCC process can cleanly and efficiently use a variety of fuels including natural gas, which is prevalent in combustion turbine combined-cycle designs. The DCCC offers a power plant design that can use lower-cost fuels such as high-sulfur residual oil and coal. The diesel engine prime mover provides a high cycle efficiency over a wider load range than does a combustion turbine to meet today`s increasing needs for operational flexibility and dispatchability of the steam and power outputs. These needs can be fulfilled with a DCCC power plant at a lower capital cost ($1,000 to $1,200/kW) than conventional steam power plants and other clean coal technologies. DCCC plants are practical from the smallest industrial plants to those with over 200 MW of capacity. These plants will providemore »
