There are two choices for an HRSG boiler design: 1) once-through, and 2) natural circulation with a steam drum. Operational issues exist with each design. For the once-through HRSG, thermal fatigue problems have been experienced due to temperature differentials within the final evaporator and the lack of proper distribution of the two-phase flow from the first evaporator. For the natural circulation HRSG with an HP steam drum, an additional amount of startup time is required to allow the drum to absorb heat so that the drum's through-wall temperature gradient is not exceeded before full gas turbine operation is allowed. In most cases, the operational guidelines for drum heat absorption must be followed even for base loading, fast starting, or load cycling. Among other things, through the use of one or more vertical separators (Figure 1) in lieu of the steam drum, …

Steam Boiler. The NUK-HP is a high-pressure natural circulation boiler operating by the gravity circulation principle. Therefore circulating pumps are not required to operate the NUK-HP®. Boiler water is used as the heat carrier. The water is evaporated in this boiler within a hermetically sealed circuit.
