Abstract:

A method of operating a co-generating steam supply system having two units, the second of which utilizes a molten-salt primary heat transfer fluid, is disclosed for utilizing the steam produced by the first unit for maintaining selected component operating temperatures in the second unit during periods when the second unit is not producing steam. The steam generator of the second unit is maintained at operating temperature by reversing the fluid flow through both the shell and tube sides. The reverse flow of molten salt is in heat exchange relation with the reverse flow of steam drawn from the steam flow line of the first unit.
