  • Rates of load change for ultra supercritical boilers

    2010-2-12 · USC ultrasupercritical units have a couple of other aspects that may cause the boiler mfr to reduce claimed ramp rate. The enthalpy at the furnace waterwall outlet is higher than at conventional SC units, which means the heat capacity at this location is small, so upsets in enthalpy lead to large upsets in fluid and metal temperature==> this
