History of ASME Standards - ASME

Two boiler explosions in Massachusetts shoe factories (Brockton 1905 and Lynn 1906) motivated the Governor to include in his inaugural address a demand for prompt action for improved public safety. One outcome of this mandate was the creation of a new Massachusetts law An Act Relating to the Operation and Inspection of Steam (1909).

Furnaces and Boilers | Department of Energy

Boilers heat water and provide either hot water or steam for heating. Steam is distributed via pipes to steam radiators and hot water can be distributed via baseboard radiators or radiant floor systems or can heat air via a coil. Steam operate at a higher temperature than hot water and are inherently less efficient but high-efficiency versions of all types of furnaces and are currently available.
