Ukusetshenziswa koMjikelezo weRankine Ezitshalweni Zamandla Ezinomusi Izitshalo Zamandla Ezinomusi (PLTU) zingenye yezindlela zobuchwepheshe zokuphehla ugesi ezisetshenziswa kakhulu emhlabeni. Zisebenza ngokusebenzisa amandla okushisa ukuguqula amanzi abe umusi ocindezelayo, oshisa kakhulu. Lawa mandla omusi abese eguqulwa abe amandla omshini nge-turbine, eguqulwa ibe amandla kagesi...

Ukuhlaziywa kwe-Entropy ku-Engineering Thermodynamic Process Kubunjiniyela, i-thermodynamics iyisisekelo esibalulekile sokuqonda ukuthi amandla ahamba kanjani futhi ashintsha kanjani ngaphakathi kwezinhlelo—kusukela ezinjinini zokushisa zangaphakathi kanye nama-turbine omusi kuya kuma-compressor kanye nezinhlelo zokuqandisa. Kodwa-ke, ngemuva kokubala amandla nokusebenza kahle kukhona umqondo oyinhloko ovame ukunquma imikhawulo yokusebenza kwenqubo: i-entropy. I-Entropy ayi… Funda kabanzi
Izinguquko ze-Enthalpy Ezinhlelweni Zokushisa Kubunjiniyela Bemishini Ezweni lobunjiniyela bemishini, izingxoxo zamandla zixhunyaniswe ngokungenakuhlukaniswa nezinhlelo zokushisa ezifana nama-boiler, ama-turbine omusi, ama-compressor, ama-condenser, ama-heat exchanger, kanye nezinjini zokushisa zangaphakathi. Elinye lamanani e-thermodynamic asetshenziswa kakhulu ukuhlaziya ukudluliselwa kwamandla kulawa madivayisi yi-enthalpy. I-Enthalpy iwusizo kakhulu ngoba ivame... Funda kabanzi
Ucwaningo lwe-Thermodynamics lwezinjini zikadizili nophethiloli Isingeniso Izinjini zokushisa zangaphakathi ziwubuchwepheshe obubalulekile obuguqula amandla amakhemikhali kaphethiloli abe amandla omshini ngenqubo yokushisa ngaphakathi kwesilinda. Izinhlobo ezimbili ezivame kakhulu ezisetshenziswa ezimotweni kanye nezicelo ezahlukahlukene zezimboni yinjini kaphethiloli (i-spark ignition/SI) kanye nenjini kaphethiloli (i-compression ignition/CI). … Funda kabanzi
Ukudluliselwa Kwamandla Ezinhlelweni Zokupholisa Nokuqandisa Izinhlelo zokupholisa nokugcina iziqandisi ziyingxenye ebalulekile yempilo yanamuhla, kusukela eziqandisini zasekhaya namafriji kuya kuma-air conditioner, kuya endaweni yokugcina ebandayo yezimboni zokudla nezokwelapha. Okuyinhloko yalobu buchwepheshe ukudluliselwa kwamandla, ikakhulukazi ngesimo sokushisa, kusuka endaweni eyodwa kuya kwenye. Okuthakazelisayo, … Funda kabanzi
Umphumela Wokushisa Ekusebenzeni Komshini Wezimboni Ukushisa kungenye yezinto ezibaluleke kakhulu emhlabeni wezimboni ngoba cishe yonke imishini isebenza ngokukhiqiza, ukudlulisa, noma ukuthintwa ukushisa. Ngokomongo wokukhiqiza, ukushisa akuhlali "kuyisitha"; ezinqubweni eziningi, ukushisa empeleni kuyimfuneko eyinhloko yokuthi imishini nezinhlelo zisebenze. Kodwa-ke, uma kungenjalo... Funda kabanzi
Ukuhlaziywa Komjikelezo We-Carnot Emishinini Yokuguqula Amandla Isingeniso Ezweni lobunjiniyela, ikakhulukazi emikhakheni yemishini namandla, izingxoxo mayelana nokusebenza kahle kokuguqulwa kwamandla zihlala ziyisihloko esikhulu. Imishini ehlukahlukene yokuguqula amandla—njengezinjini zomusi, ama-turbine egesi, izinjini zokushisa zangaphakathi, kanye nezinhlelo zokuqandisa—empeleni zizama ukuguqula amandla kusuka kwesinye isimo aye kwesinye ngokulahlekelwa okuncane. Kodwa-ke, … Funda kabanzi
Izibalo Zokusebenza Kahle Kokushisa Kwezinjini Zanamuhla Zomusi Izinjini zomusi zivame ukubhekwa njengobuchwepheshe "obujwayelekile" obuvela eNguquko Yezimboni. Kodwa-ke, izimiso nentuthuko yazo zisasebenza nanamuhla, ikakhulukazi ezitshalweni zamandla ezisebenzisa umusi (i-PLTU), izitshalo ezikhiqiza ndawonye (ukushisa okuhlanganisiwe namandla/i-CHP), kanye nezinhlelo ze-turbine zomusi embonini yenqubo. "Izinjini zanamuhla zomusi" zibhekisela ezinhlelweni zokukhiqiza amandla... Funda kabanzi
Izifundo Zokushisa Nokucindezela Ezinhlelweni Zokushisa Zezimboni Izinhlelo zokushisa zezimboni ziyinhliziyo yezinqubo eziningi zokukhiqiza zesimanje—kusukela ekukhiqizweni kwamandla nokucubungula uwoyela negesi kuya kumakhemikhali kaphethroli, imboni yokudla neziphuzo, ngisho nemithi. Ngemuva kokusebenza kwalezi zinhlelo, iziguquguquko ezimbili ezibaluleke kakhulu zenqubo izinga lokushisa nokucindezela. Zingaphezu nje kwezinombolo kuphaneli… Funda kabanzi
Ukuhlaziywa Kokudluliselwa Kokushisa Ezinjinini Zokushisa Zangaphakathi Isingeniso Injini yokushisa yangaphakathi (i-ICE) iyithuluzi lokuguqula amandla eliguqula amandla amakhemikhali kaphethiloli abe amandla omshini ngokushiswa ekamelweni lokushisa. Kule nqubo, ukudluliselwa kokushisa kudlala indima ebalulekile ngoba kunquma ukusebenza kahle, ukusebenza, ukukhishwa, kanye nokuthembeka kwenjini. Ukushisa okukhiqizwa ukushiswa aku... Funda kabanzi
