Analysis of thermodynamic losses in regeneration systems of the extraction back-pressure power unit in a combined heat and power plant
(Wydawnictwa AGH, 2007) Tokarz, Tadeusz; Karpiel, Tomasz
An algorithm is developed for computing thermodynamic losses in the regeneration systems of the back-pressure power unit in a combined heat and power plant. Thermal measurements taken under the typical working loads were utilised to compute and analyse variability of the thermodynamic losses in heat exchangers of the high-pressure and low-pressure regeneration systems in the heating and pseudo-condensing modes of operation.

Application of selected balance methods to the evaluation of performance parameters of the extraction back-pressure power unit in a combined heat and power plant
(Wydawnictwa AGH, 2008) Tokarz, Tadeusz; Karpiel, Tomasz
Thermal measurements of the extraction back-pressure power unit in the combined heat and power plant for a wide range of working loads were utilised to develop an algorithm for computing performance parameters of the power unit. The calculation procedures use the enthalpy balance method and the entropy balance method. Adequacy of the two methods was compared on the basis of performance characteristics of the investigated power unit.
