  • BOILER BASICS AND TYPES OF BOILERS, DIFFERENCES

    A boiler is a steel pressure vessel in which water under pressure is converted into steam by the application of combustion. In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads. TYPES OF BOILERS. There are two types:
