Abstract:

Použití superkritické vody v energetice je motivováno zvýšením tepelné účinnosti energetického cyklu. Důsledkem vyšší účinnosti je snížení specifi ckých emisí CO2. Superkritické energetické cykly byly proto zařazeny mezi čisté uhelné technologie (CCT - Clean Coal Technology). Vzhledem ke korozní agresivitě superkritické vody je základním požadavkem volba správného konstrukčního materiálu. Všechny typy ocelí, testovaných v této studii, byly použity při konstrukci komponent superkritického energetického bloku. Ke studiu byly vybrány celkem čtyři typy žáropevných ocelí, z toho dva typy austenitic

Abstract:

Shrnutí Tento příspěvek obsahuje informace o přerozdělení tepla v současných vozidlových spalovacích motorech. Vycházelo se z různých konstrukcí především zážehových motorů s rozdílnými zdvihovými objemy, vznětové motory jsou však také zmíněny. Je zde uveden postup výpočtu tepelné bilance motoru, stejně tak, jako obtíže spojené se získáním vstupních dat měřením. Byl navržen a ověřen empirický vztah pro výpočet tepelného toku do chladící kapaliny, který umožňuje snadné nalezení nekorektně změřených pracovních bodů motoru už v počáteční fázi automatického měřícího cyklu. Naměřené hodnoty byly sr
