ABMA paper 9 00 - Johnston Boiler

A longstanding rule of thumb for firetube boilers is 5 ft2 of heating surface area per boiler horsepower. This number has been used in the ASME code to set firing rates and steam generation capacities and is typical for the majority of boiler manufacturer's designs. However, through the use of new tube technology, the 5 ft2/bhp can be
