The Novikov and Curzon-Ahlborn approaches which lead to the improving of the classical Carnot effectiveness expression in the direction of its diminishing were studied in this paper. This effect is due to the account for finite time of non-isothermic processes of the heat exchange which lead to the non-zero values of the thermal machine output power. Obvious expressions for these values are found in both analytic and graphical forms.
