label: Description
content: This model is of a boiler having water tubes made up of large tubes closed at the ends with smaller tubes suspended within the large tubes to provide a circulation of steam and water upward in the smaller tubes and of the cooler water down ward in the annular spaces between the larger and smaller tubes. The inventor suggests the use of tubes of different metals to produce a galvanic action for the purpose of preventing deposits of scale within the tubes.
label: Description
content: The boiler represented by the model consists of a series of vertical tubes suspended into the furnace from a horizontal header across the top of the boiler setting. The tubes closed at their lower ends, and within each tube is one of smaller diameter. The smaller tubes are suspended from a plate within the header. The headers connecting each row of tubes across the boiler are, in turn, connected by a longitudinal drum above them.
