Combined operation of 900MW power plant with the ORC through the bleed steam extraction point and CO2 recovery system
PublicationThe work presented here is aimed at utylisation of waste heat in the reference supercritical power plant in the manner to produce electricity in ORC installation. The waste heat is available in the form of a stream of hot water at 90 C, recovered from the exhaust gases in the amount of 200MW. Such low enthalpy heat source is rather insufficient to produce a good quality vapour to feed the ORC turbine. Therefore an original approach...

Limiting distribution of the three-state semi-Markov model of technical state transitions of ship power plant machines and its applicability in operational decision-making.
PublicationThe article presents the three-state semi-Markov model of the process {W(t): t 0} of state transitions of a ship power plant machine, with the following interpretation of these states: s1 – state of full serviceability, s2 – state of partial serviceability, and s3 – state of unserviceability. These states are precisely defined for the ship main engine (ME). A hypothesis is proposed which explains the possibility of application...

PublicationStosowane powszechnie w planowaniu rozwoju systemów transportowych modele rozkładu ruchu w sieci najczęściej nie uwzględniają wpływu zjawiska zatłoczenia na zmiany zachowań transportowych mieszkańców. Zmiany te przejawiają się w rezygnacji z podróży w godzinach szczytowych, ograniczeniu długości podróży lub wyborze alternatywnego środka transportu. W referacie przedstawiono charakterystykę metod rozkładu ruchu, które pozwalają...
