If a malfunction of an FSG is suspected, it should be tested on a tester built for this purpose. Mr. Doran also concluded that damage was very extensive and required replacement of the entire boiler, controls, and stack. The explosion consisted of the ignition of a large accumulation of natural gas fuel in the combustion chamber, which caused the pressure boundary to be broken. Traditionally, many boiler operators were former boiler technicians who had received training in the U.S. Navy. But now that the Navy has converted most of its ships' propulsion systems from steam to gas turbines or diesel electric, it is harder to find trained operators.
Several routes help ensure safety for all fuel and pressure items in school settings.
First, it is important to purchase equipment built to the ASME Boiler and Pressure Vessel Code and registered with theNational Board, and to see that the equipment is installed according to manufacturer's instructions and jurisdictional requirements. Second, care must be taken when ordering replacement parts. This codealso does not allow the use of rebuilt or altered controls. Third, ensure that adequate training is provided for all personnel who might operate or repair a boiler or other fuel burning device. The chief boiler inspector for each jurisdiction can assist in identifying available training.
