- Abstract
- As part of the research program on heating plants for small homes being conducted at the National Bureau of Standards in collaboration with the National Housing Agency and its technical staff, the performance characteristics of cast-iron boilers, both coal- and oil-fired, have been investigated. This report discusses the performance of a cast-iron boiler designed for coal firing after it had been converted to the use of oil by means of a gun-type burner. It is shown that a refractory firebox of low heat capacity and low thermal conductivity increased the efficiency of the converted boiler several percent, and that baffles which effectively direct the hot combustion gases over the heat-transfer surface increased the capacity of the boiler up to 27 percent.
