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

摘要

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.
