... Abstract A test flight was cut short after a fire warning came on indicating a problem with one of the four engines on an aircraft. A visual examination following the precautionary landing revealed several burned hoses, a melted bolt, and fuel leaking from the base of the main burner. The fuel...

... difficulty in scale removal was traced to the open hearth, gas-fired annealing furnaces. It was found that the atmosphere was reducing while the burners were on, and that a thin, tight scale was produced. A satisfactory remedy was to adjust the burners to bring the oxygen content to 3%.
