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.

2004-3-19·Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

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.
