Utilisation of waste heat from the power plant by use of the ORC aided with bleed steam and extra source of heat
Utilization of waste heat recovered from the exhaust gases of the power generation unit by means of ORC (organic Rankine cycles) installation is considered. The waste heat is available in the form of a stream of hot water having temperature of 90 stC in the amount of 200 MWt. To increase evaporation temperaturę of ORC working fluid the heat of steam from the extraction points from the low-pressure part of steam turbine is used....

Experimental investigation of dryout of SES36, R134a, R123 and ethanol in vertical small diameter tubes
W publikacji przedstawiono wyniki badań eksperymentalnych kryzysu wrzenia typu dryout podczas wrzenia w przepływie czterech czynników (SES36, R134a, R123, alkohol etylowy) w kanałach o średnicy wewnętrznej 1.15 mm i 2.3 mm. Badania przeprowadzono w szerokim zakresie zmian stopnia suchości pary (0.65-1), gęstości strumienia masy (40-900 kg/(m2s)) i gęstości strumienia ciepła (20-220 kW/m2). W badaniach wykorzystano technikę termowizyjną...

Influence of metallic porous microlayer on pressure drop and heat transfer of stainless steel plate heat exchanger
The experimental analysis of passive heat transfer intensification in the case of plate heat exchanger has been carried out. The metallic porous layer was created on the heat transfer surface of analyzed unit. The experiment was accomplished in two stages. In the first stage the commercial stainless steel gasketed plate heat exchanger was investigated, while in the second one – the identical heat exchanger but with the modified...
