  • Mass Flow Measurement Using Heat Transfer Method for Moved Bed Gravity Flow

抄録

This paper is concerned with the first novel massflow measurement of stand pipe for moved bed gravity flow. Aim of this study is the confirmation of a novel massflow measurement methods for gravity flow in stand pipe in the new process that is high calorie coal gasifier or direct reduction process. The gravity flow in stand pipe is required for high pressured, high temperatured and corrosive feed conditions. This paper describes heat transfer method based on one of the author's efforts for pulverized coal injection system. It is required for reducing accuracy. It is clearized by the authors that the wall temperature is the most important for the system and there is a boundary layer heat transfer on the inside surface of the pipe.<br>Scale up of meter size and expansion of feed specification will be studied in the next stage.
