Boiler cycles calculation
WebThe 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. ... WebMay 24, 2016 · Basement zone calls would short cycle. Ideally, the replacement boiler would fix those problems. Operating at 180°F AWT, the smaller first-floor zone would still be emitting 36,000 BTU/hour of the 42,000 BTU/hour boiler output, and cycling on single zone calls would be reasonable utilizing just the thermal mass of the boiler.
