In this paper the technologies for heating reserve liquid fuel at a thermal power plants are proposed. Provision is made to implement a transition from fuel oil to another reserve fuel that does not require high-temperature heating at thermal power plants. A comparative analysis of the traditional scheme of heating reserve fuel with industrial steam and other coolants was carried out. The analysis was carried out using the exergy method, which allows taking into account different types of power. Exergy flows, exergy losses and exergy coefficient of efficiency are calculated for traditional and proposed technologies of reserve fuel heating.
