Once Through Steam Generators | Inproheat

2019-9-23·Once Through Steam Generators (OTSGs) are very similar to Heat Recovery Steam Generators (HRSGs) except for the actual process of steam generation in their evaporator section(s). N/E under a license from Siemens AG utilizes two single pass evaporator stages to evaporate and partially superheat the steam flow in the once through evaporator section.

J.W. Smith Supercritical (Once Through) Boiler

2018-3-26·In Europe, boiler technology followed the once through philosophy. This at least in part was driven by material availability constraints and took advantage of the fact that the once through boiler generally used smaller diameter and thinner walled tubes then did the natural circulation boiler.

Energy Saving by Introduction of High Efficiency Once

The advantage of once-through boiler (project boiler) is that the high efficiency can be maintained under the low range of operation load. On the other hand, efficiency of oil and gas fired fire tube boiler is low at the smaller operation load range. Figure 1 is the test result of efficiency comparison

In a sliding pressure boiler, the phenomenon like shrink and swell effect which occurs immediately when the boiler turns off or when the boiler is in the start up phase (under 35% load). In these cases, the dynamics of once-through boiler is the same as a drum boiler. The start-up control valves are activated to cope with these conditions.
