摘要: Abstract The paper presents use of energy and exergy analyses for the assessment input output flows in a cogeneration plant, shows points degradation system allows to make quantitative evaluation quality changes. objective study is determine essential values destruction biomass combined heat power (CHP) plant Jelgava, as well define boundaries method's use. A mathematical model elaborated, used evaluated suitable its application real may be plant's further operation efficiency improvements. results are shown with Sankey Grassmann diagrams; largest occurs boiler (steam generator) represents 63.7% fuel exergy; second observed exchangers district heating (DH) system. Exergy influenced by ratio (α) potential produced (temperature). Increased load or decreased temperature delivered consumer lowers value plant.
