The Scale-Up of Large Pressurized Fluidized Beds for Advanced Coal-fired Power Processes

More refinement was added to the five sample ports that were installed along the cold model riser. Each sample port is now equipped with an electrically actuated X ball-valve that can be operated from a switch in the main control panel area. These actuated ball valves control the on/off position of the sample port. They are switched on for a desired period of time for sample collection during a test run. They are particularly useful for the hard-to-reach sampling locations near the top of the riser where manually operating a ball-valve could be difficult

Advanced wet-dry cooling tower concept cross-flow tests

The design, operation, instrumentation, and performance testing of a crossflow evaporative cooling tower are discussed, and computer predictions for performance are compared with test data. Experimental results for 14 runs agreed with heat and mass transfer coefficient calculations within 5% for 11 runs and within 8% for the remaining 3 runs. It was concluded that the computer model is valid for use in future design studies, that the wet-dry packing is effective in reducing cooling water consumption, and that the crossflow air-water arrangement shows much promise for future development.
