HRSG (Hear Recovery Steam Generator) is a boiler to recover heat from the exhaust gas of an engine and generate steam for more power generation or process. For the HRSG, water-tube type boiler has a steam drum to separate steam from the water-steam mixture supplied from the evaporator tube(riser). The drum should be sized properly to separate the steam by the gravity and auxiliary internals such as a demister are installed to filter the steam. To size the steam drum and to estimate the filter efficiency of drum internals, the velocity distribution inside the drum need to be identified. In the present study, a series of CFD has been conducted to find the velocity distributions inside steam drums for conventional HRSGs and water-tube type industrial boilers. The velocity distributions obtained from the simulation have been normalized and a correlation to predict them has been found. The correlation is applied to the steam drum design by determining a proper position of a demister to show proper separation performance.
