Heat reservoir for a power plant
First Claim
1. A process for producing electric power from burning a dirty fuel comprising the steps of:
- combusting a dirty fuel to produce a dirty hot gas flow;
passing the dirty hot gas flow through a dirty passage formed on one side of a heat absorbing wall so that the heat absorbing wall will absorb heat;
when the heat absorbing wall has absorbed a certain amount of heat, passing a clean compressed air through a clean passage formed on an opposite side of the heat absorbing wall so that the clean compressed air will absorb heat from the heat absorbing wall to produce a clean hot gas flow;
equalizing a pressure across the heat absorbing wall during the passing of the dirty hot gas flow and the clean hot gas flow through the clean and dirty passage; and
,passing the clean hot gas flow through a turbine that drives an electric generator to produce electric power.

Abstract
A heat reservoir for use in a power plant that burns a dirty fuel such as coal to absorb the heat from the resulting dirty hot gas flow. The heat reservoir includes a number of heat absorbing walls that form dirty hot gas flow passages and clean hot gas flow passages. Cross-over holes are formed in the walls to equalize pressure. The dirty hot gas flow is passed though the dirty passages to heat up the walls. When the heat absorbing walls have absorbed enough heat, the dirty hot gas flow is stopped and compressed air is passed through the clean passages to absorb heat from the walls and is then passed through a turbine to drive an electric generator. The heat reservoir is then recharged again by passing the dirty hot gas flow through the dirty passages to recharge the walls.
