USE OF COAL DRYING TO REDUCE WATER CONSUMED IN PULVERIZED COAL POWER PLANTS
This is the fifth Quarterly Report for this project. The background and technical justification for the project are described, including potential benefits of reducing fuel moisture, prior to firing in a pulverized coal boiler. A theoretical model, for computing the effects of dryer design and operating conditions on performance of a continuous flow fluidized bed dryer, operating at steady state conditions, is described. Numerical results from the model, compared to data from a pilot scale lignite dryer located at Great River Energy's Coal Creek Station, show good agreement. The dryer model was used to perform parametric calculations on the effects of dryer design and operating conditions on dryer performance and required in-bed heat transfer. Other analyses show the first order effects of firing lignite and PRB coals, dried to various moisture levels, on flow rates of coal, combustion air and flue gas, fan and mill power and unit heat rate.
