This demonstrates the myth that a boiler bypass circulator, by itself, is insufficient to protect the boiler. The missing element is a mixing system that senses and reacts to the boiler inlet temperature. The system in Figure 4 uses a mixing valve controller that measures

Read MoreThe flue gases are relatively slow moving in the flues of Lancashire-boiler and in order to abstract as much heat as possible, the heating surface area and hence its length is quiet great. In order to recover still further quantities of heat a secondary heating surface is added in the shape of an economizer.
