The power industry faces many challenges based on increased competition and stringent environmental regulations. Fuel firing options involving coal and natural gas offer economic and environmental benefits. Proper evaluation of the effects of natural gas firing on generation cost includes consideration of the following: seasonal and long-term fuel prices (coal and gas), alternative gas firing technologies and plant operating requirements. This paper describes the development of a SOAPP{trademark} (State-of-the-Art-Power-Plant) software Module that provides the capability of quickly evaluating four gas firing technology options for coal fired units using a personal computer (PC). The Module provides technological process information, computes boiler and plant performance, develops capital and O and M cost estimates and provides overall economics on the various types of coal and natural gas firing technologies. The gas firing technologies considered include cofiring, reburning, seasonal gas firing and gas conversion on a plant currently firing a user defined coal. The inputs to the Module include the turbine, boiler, major balance of plant parameters, emission controls and limits and economic evaluation basis. The results, displayed in terms of unit load, time duration, coal fuel analysis and coal and natural gas firing fractions are sufficiently detailed for performance and overall economic evaluations related to a plant retrofit or change in operation.
