The Brotan Boiler. - Douglas Self

Oct 19, 2014 · "The Brotan boiler is well designed and steams freely on account of the water tube firebox; the steam produced, however, is wetter than in an ordinary boiler. The efficiency of the boiler is good and from tests carried out by the Polish State Railways the consumption of fuel in a Brotan boiler is about 5% less than in a boiler of orthodox type.
