Abstract

The invention relates to a method for recovering heat by joining a plurality of heat flows of a fossil-fired, in particular carbon-fired, power plant (1), which downstream of the combustion comprises a CO₂ scrubbing station (58) for the flue gas by way of chemical absorption and/or desorption and associated CO₂ compression (27), which method aims to enable a CO₂ scrubbing station for the flue gas, with associated CO₂ compression, to be integrated into the total energy heat flow and/or the total heat energy balance of a fossil-fired, in particular carbon-fired, preferably conventional, power plant in a way that is advantageous in terms of heating technology. This is achieved by decoupling thermal energy from the heat flow of the CO₂ scrubbing station (58), with associated CO₂ compression, in the form of at least one partial heat flow (Q₈, Q₉, Q₁₀, Q₁₁) and coupling it back into a heat flow that is coupled, directly or indirectly, to the heat flow of the boiler (2) or steam generator of the power plant (1), and/or by decoupling thermal energy from the flue gas heat flow (Q₃) in the form of a partial heat flow (Q₁₂, Q₁₃, Q₁₄) and coupling it back into the heat flow of the CO₂ scrubbing station (58) with associated CO₂ compression (27).
