Assessment of Existing Equipment when Converting to Natural Gas Firing
It is strongly encouraged to maintain records of these monthly inspections to assess degradation and any modifications made to the equipment. This will help facilitate any inquiries to the original equipment manufacturer (OEM) on replacement parts and any upgrades required in the event either unit cofires coal in the future. Special attention should be given to dry rot, moisture, and corrosion. In the event that substantial dry rot or corrosion is detected, it is recommended to consult with the OEM for recommendations on corrective action. Continue reading
Paper: Conversion of Coal-Fired Electric Generating Units to Natural Gas-Fired Units
Historically, natural gas supply has been consistent in quality and heating value throughout the United States. Gas properties have also been consistent, with slight variations, making the risk of a significant error in engineering and design of gas-fired equipment quite low. Table 1offers a representative fuel analysis for natural gas. Continue reading
