The forced circulation helps in to increase the water circulation along with uniform heat distribution throughout the boiler water thus results in rapid steam generation at high pressure. The boilers of high capacity such as Lamont, Velox, power boilers, etc. fall under this group.

Steam Boiler vs Hot Water Boiler - ATI of NY

2016/10/12 · Safety & Efficiency. In comparison to steam boilers, hot water boilers have been traditionally safer. At the same time, the efficiency of steam boilers has traditionally been less than that of hot waters. The reason for this difference is due to the fact steam boilers do not use motor pumps to enhance circulation.

LaMont steam boiler

The LaMont boiler is a once-through or semi-flash boiler in which the boiler water is circulated by means of a pump through long closely spaced tubes of small diameter. The tubes end in a steam separating drum where the emulsion of steam and water separates. The LaMont boilers require powerful pumps for the forced circulation of the boiler
