Supercritical Boiler - Babcock & Wilcox

The steam separator acts like a drum in a natural circulation boiler. The fluid from this separator is recycled to the economizer inlet where it mixes with feedwater to maintain the minimum flow through the boiler furnace. Once minimum load is achieved, the startup system is put in warm standby for quick use when required.

What is a Steam Boiler? Working, Types of Heat

It is a fire tube, horizontal, internally fired, and natural circulation boiler, stationary and low-pressure boiler. Since it is a low-pressure boiler steam production will be less. Due to the lower steam production, the efficiency of the boiler is also low compared to the water tube boiler. The Lancashire boiler is shown in the figure below.
