INDUSTRIAL INTERFUEL SUBSTITUTION PHASE I REPORT: MODEL

dramatic decline in coal as a boiler fuel in industry and in utilities because of the relatively lower cost of oil and the concern for environmental quality associated with coal combustion. The decade of the seventies began with a major change in the relative economics of coal, oil, and natural gas. Oil became expensive and occasionally scarce;

Combustion Testing Procedures

While stack draft may be an important measurement, fuel oil and gas fired power burners require draft control over the fire to maintain a proper and controlled intake of combustion air. Comparing stack and overfire O 2 can verify that leakage between boiler sections, access door, etc is minimal and the combustion test results are accurate.
