The primary and secondary air flows, temperatures, gasification rates, and particulate emissions were monitored over the full operating range of a corncobfueled, downdraft, channel gasifier. The maximum capacity of the unit was about 787,000 Btu/hr, with a turndown ratio of almost 3:1. Test results revealed that (1) the primary airflow was a major factor in controlling the gasification rate and (2) particulate emissions were approximately proportional to the second power of the gasification rate. Engineers generally concluded that the down-draft channel gasifier is a simple, energy-efficient design, allowing the controlled thermochemical conversion of corncobs into heat energy.
