Additionally, since the tube holds less water than the water tank of a fire tube design, it takes less time to turn that water to steam — and by extension, less fuel. A water tube boiler produces steam in as little as five minutes, compared to an hour or more for fire tube boilers. As a result, fuel savings costs can be significant over time.

This boiler shows a reversal chamber that is surrounded by water, uses as a medium to direct fluegasses from the furnace to the tube. The surrounding water captures heat, increasing the operationalefficiency as heat from the combustion passes rapidly into the warm heating water instead of refractory.It uses a separate tube sheet, between tubes passes tobe more pardoning with load changes.

It is a water tube, forced circulation boiler, where the feed water is compressed to supercritical pressure to prevent the formation of bubbles in the water tube. The compressed water feed increases the density of the water such that its density and that of the steam become the same, which reduces the latent heat in the water to zero making it easier to convert to steam.
