Abstract
A Frasch process sulphur mine power plant is coupled to a steam-electric generating plant by a coupling heat exchange means, wherein the heat liberated by condensing steam is substantially used to bring Frasch mine water up to operating temperature.
Claims8
A method of coupling a steam-electric generating station to a Frasch process sulphur mine so that a portion of the waste heat from electric generation can be used in the process of mining sulfur, comprising the steps of
- establishing a coupling heat exchange means,
- diverting exhaust steam from the steam-electric generating plant into the coupling heat exchange means,
- circulating mine water through the coupling heat exchange means,
- reducing the pressure of the steam within the coupling heat exchange means,
- condensing the steam into water within the coupling heat exchange means with the resultant liberation of heat,
- transferring the heat from the hotter steam and condensed steam to the cooler circulating mine water,
- withdrawing the mine water, and
- directing the mine water to the sulphur mine.
