Abstract

The present invention provides a method for operating a combined heat and power (CHP) plant comprising a heating boiler, a vaporizer, an expansion machine, and a condenser, achieved according to claim 1. The method comprises steps a), when a first condition is met: supplying a working medium to the vaporizer to obtain an at least partially evaporated working medium, feeding the (total) evaporated working medium to the expansion machine, and operating the expansion machine such that the working medium is expanded, supplying the working medium expanded by the expansion machine to the condenser, and transferring heat of the expanded working medium supplied to the condenser to a medium of a heating circuit designed to heat an object; and b) when a second condition is met which is different from the first condition: i) supplying at least a portion of the working medium to the condenser of the CHP plant without the portion of the working medium having been supplied to the expansion machine, and transferring heat of the working medium supplied to the condenser to a medium of a heating circuit designed to heat an object, and/or supplying a medium supplied from the heating boiler to the vap…
