The combination of historically low gas prices and pressure from more stringent emission requirements for combustion operations has led to a wave of plant conversions from coal to gas as the fuel for power-generating equipment. Conversions, as opposed to completely new facilities, pose a challenge regarding how much of the existing system can be used as part of the converted system. One aspect of that challenge is the valves on the existing system.
Crane ChemPharma & Energy, a globally recognized manufacturer of industrial valves for a wide range of applications, authored a white paper covering the subject of valve usage and replacement in power generation facilities converting from coal to gas. The paper provides a useful overview of the current state of power-generating facilities with respect to regulation and the anticipated supply and cost of gas in the future.
