A Steam Heating Primer

Jun 25, 2014· Let’s take a look at some of the other changes manufacturers have made to boilers in recent years. The importance of the Piping Around the Boiler. As boilers became smaller, the piping around them became more and more important. Today’s replacement steam boiler contains much less water than the boilers of yesteryear.


Efficiency —The term “efficiency”, specifically applied to a steam boiler, is the ratio of heat absorbed by the boiler in the generation of steam to the total amount of heat available in the medium utilized in securing such generation. When this medium is a solid fuel, such as coal, it is impossible to secure the complete combustion of the total amount fed to the boiler.


Steam Boiler— A closed vessel for conversion of water into steam. It should be equipped with automatic controls to maintain water level and sufficient safety devices for proper burning of fuel. Square Foot of Heating Surface— Equivalent Direct Radiation (EDR) the amount of heating surface which will give off 240 Btu per hour when
