Abstract

Experiments with a gas–solids dense phase pneumatic pipe flow have been undertaken: (1) to determine the average heat transfer coefficient between a heated wall and a gas–solids dense phase flow; (2) to investigate the heat transfer mechanisms of pneumatically conveyed dense phase flow in detail as the system operates by injecting heat energy into the pipeline to heat the pipe section, as a result, to heat the dense phase gas–solids¿ plugs, and measuring the resultant change in solids¿ plug and heated wall¿s temperatures. The experimental results suggest that the average heat transfer coefficient between the heated wall and the gas–solids dense flow displays an approximately linear relationship with the solids loading ratio. A larger solids¿ loading ratio results in a higher average heat transfer coefficient.
