During operation, the tubes exposed to the radiant heat from the flame are always producing steam. As the steam rises in the tubes, boiler water is also carried upward and discharged into the steam drum. Tubes that are not producing significant steam flow have a net downward flow of boiler water from the steam drum to the mud drum.Get Price

Oct 06, 2017 · The term HRSG refers to the waste heat boiler in a Combined Cycle Power Plant. In its basic form these are bundles of water or steam carrying tubes paced in the hot gas flow path. These recover the heat from the gas to generate superheated steam, hence the name Heat Recovery Steam Generator.Get Price
Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.Get Price
