LaMont boiler

The LaMont boilers forced water circulation and the tubes of small diameter gives enormous freedom as far as the design of the heating surfaces concern.
With its features of positive circulation, compactness, light weight, suitability for high pressure and temperature, and adaptability to limited space conditions, the Controlled Circulation can offer important advantages for advanced-designed marine boilers.

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 water.
