Analysis of the thermodynamic losses in the regeneration system of the extraction condensing type power unit at a combined heat and power plant
(Wydawnictwa AGH, 2006) Tokarz, Tadeusz
The paper outlines the method of evaluating thermodynamic losses in the regeneration systems of the extraction condensing type power unit in a combined heat and power plant. The exergy analysis principles were then utilised to compute the thermodynamic losses in heat exchangers of the high-pressure regeneration system in the heating and condensing mode of power unit operation. Finally, the thermodynamic losses are expressed in terms of increased fuel consumption in the boiler, which is of key importance for the calculations of overall costs of power and heat generation in a combined heat and power plant. KEYWORDS: combined heat and power plant, extraction condensing type power unit, regeneration system, thermodynamic losses, energy analysis.

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.

Evaluation of performance parameters of the extraction condensing type power unit at a combined heat and power plant
(Wydawnictwa AGH, 2006) Tokarz, Tadeusz
Fundamental relationships defining the effectiveness of regeneration processes in steam power stations were precisely formulated. Characteristics of a extraction condensing type power unit with the regeneration systems at a combined heat and power plant were obtained experimentally for a wide range of operating loads. The energy analysis would yield the optimal range of performance parameters of the power unit for the heating and condensing working modes.
