Focuses on boiler safety operation and maintenance. Process of heat transfer in a watertube boiler; Reasons for boiler failure; Cause of fuel explosions. INSETS: Common causes of fuel explosions;Boiler safety operation and maintenance practices.

The article discusses the 12 sections of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code. It also describes ASME codes that establish standards for boiler system components including the B31 series for piping and the controls and safety devices. It outlines the resources provided by the American Society of Heating Refrigerating & Air-Conditioning Engineers (ASHRAE) that relate to the design and performance assessment of boiler systems.

Studies five areas in which safety problems in boilers are likely to develop. Pressure valves; safety valves; Water-level controls; Combustion; Condensation; Other safety considerations.
