A Steam boiler is a steel pressure container in which water under pressure is transformed into steam by the use of combustion. In other words, the boiler is just a heat exchanger which uses radiant heat and hot flue fumes, released from burning fuel, to produce vapor and hot water for heating and processing loads.
