Chapter Three - How Steam Boilers Are Made . A steam boiler heats water much like a teapot, only on a larger and more complex scale. Though not every steam boiler is the same, there are basic elements that are common to all steam boilers: burner, combustion chamber, heat exchanger, expansion tank, steam temperature control, safety relief valve, and low water cutoff.
