ABSTRACT
Microturbines have been demonstrated to be reasonably well suited to run on waste or bio-gas. The main reason is that waste gas is generally free fuel and therefore the economic value is greatly increased. Microturbines generally operate in the 20% to 25% electric efficiency range. With free fuel the “cost to generate” is zero, excluding the cost for equipment and maintenance. Two (2) Honeywell Power Systems Parallon 75® microturbines were installed a waste processing facility in Philadelphia, PA. The major benefit to installing the microturbines was the avoided costs in environmental permitting, controls, monitoring and reporting. This article is a summary of the project activities and results of the project.
