    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.

    High-efficiency ceramic recuperators to glass furnaces
    (2006) Karczewski, Krzysztof
    Mathematical model of high-efficiency ceramic recuperators using the new generation of shapes was elaborated. The parameters and characteristics magnesia, fusion cast alumina-mullite-zirconia, chamotte recuperator shapes were compared. Ceramic recuperator to glass tank was calculated by the model.
