Steam drums The cycling of utility drum boilers has the potential to produce significant variation in drum temperatures. The drum is a large thick-walled vessel that inherently responds slowly to temperature changes. Top-to-bottom variations in drum temperature can lead to drum humping, excessive stresses on connections, and fatigue in welds.
