The typical evaporator is made up of three functional sections: the heat exchanger, the evaporating section, where the liquid boils and evaporates, and the separator in which the vapour leaves the liquid and passes off to the condenser or to other equipment. In many evaporators, all three sections are contained in a single vertical cylinder. In the centre of the cylinder there is a steam heating section, with pipes …

Water drum is present only in the bidrum steam boilers and play a less important role such as: a water drum acts like a large header connecting the riser and downcomer tubes of the bank, and it feeds the downcomers to the various evaporator sections. The water drum is always smaller than the steam drum as there are no important internals.

The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the steam in order to increase its enthalpy.

15/10/2019 · In the present work, the overall behavior of a steam boiler is investigated using RELAP5/MOD3.2 system code at three different operating loads. Main thermal–hydraulic parameters are analyzed at steady-states corresponding to 60%, and 110% of the boiler nominal load. RELAP5 system code is widely used in the design and safety analysis of nuclear reactor installations as well as …

1. In the evaporator section, the liquid receives heat and becomes vapor (process 1–2) 2. The vapor travels through the adiabatic section due to pressure difference between the evaporator and the condenser (process 2–3) 3. In the condenser, the vapor releases heat and becomes liquid (process 3–4) 4.
