Scaleup tests and supporting research for the development of duct injection technology: Topical report No. 7, Task 4.1: Testing of first generation mathematical model predictions; Topical report No. 8, Task 4.2: Testing of second generation mathematical model predictions, Duct Injection Test Facility, Muskingum River Power Plant, Beverly, OH

Abstract

Gilbert/Commonwealth (G/C) and Southern Research Institute have completed a project under DOE sponsorship entitled ``Scaleup Tests and Supporting Research for the Development of Duct Injection Technology``. The project included extensive modifications to DOE`s Duct Injection Test Facility (DITF) located at the Muskingum River Plant of Ohio Power Company. A comprehensive test program was performed at the facility to evaluate So{sub 2} removal and overall process operability with duct injection of slaked lime slurries and dry injection of calcium hydroxide powder with humidification. Detailed results from the project are presented in the following reports: Topical Report No. 1 -- Literature Review; Topical Report No. 2 -- Evaluation of System Performance; Topical Report No. 3 -- Scale-Up Testing; Advanced Configurations Process Controls; Failure Modes; and Waste characterization. Project Final Report. The purposes of this report are: (1) to satisfy a contractual requirement for a separate topical report concerning the subject of mathematical model validation, and (2) to briefly describe the status of the model development and validation effort.
