    This is because the volume of hot water that would instantly turn to steam when the pressure dropped (eg because of a rupturing vessel) was vastly less than in even a small fire-tube boiler. Speaking of pressures, those achieved in the water tube boilers could be much higher than in a fire-tube design.

    The primary function of a boiler is to transfer heat from hot gases generated by the combustion of fuel into water until it becomes hot or turns to steam. The steam or hot water can then be used in building fire-tube boilers and water-tube boilers. Fire-tube boilers pass hot combustion gases through (CO2) by the heat and pressure of the
