I-grate ye-incinerator yemfucuza iyingxenye eyinhloko ye-mechanical grate incinerator, futhi ukwakheka kwayo kuthinta ngqo ukusebenza kahle kokushiswa kwemfucuza kanye nomphumela wokwelapha.
Njengengxenye eyinhloko yokushiswa kwemfucuza, ukukhethwa kokubalulekile kwe-grate yokushisa imfucuza kudinga ukucabangela izici ezifana nokumelana nokuguga, ukumelana{0}}nokushisa okuphezulu, ukumelana nokugqwala kanye nomnotho. Izinto eziyinhloko zifaka -i-chromium cast iron ephezulu ne-alloy cast steel.
Incazelo Yemikhiqizo
Izinto ze-grate kumshini wokushisisa zinomthelela omkhulu kumphumela wokushiswa. Izici ezinjengokumelana-nokushisa okuphezulu, ukumelana nokugqwala, ukunwetshwa kwe-thermal, ukuqhutshwa kokushisa, namandla okusebenza e-grate kunquma ngokuqondile impilo yesevisi, ukuqina kokushiswa, ukusebenza kahle kokuphathwa kwemfucuza, kanye nezinga lokungcoliswa kwe-grate. Okulandelayo imithelela ethile kanye nokuhlaziya:
Umthelela oyinhloko wezakhiwo ezibonakalayo kumphumela wokushiswa
Ukumelana nokushisa
Umthelela: Izinga lokushisa ngaphakathi kwesishisi ngokuvamile lisukela ku-850 kuya ku-1200 degrees. I-grate idinga ukumelana nokushisa okuphezulu isikhathi eside ngaphandle kokuthambisa, ukukhubazeka noma ukuphuka.
Icala: Insimbi ye-carbon evamile izongena ngokuphawulekayo emazingeni okushisa angaphezu kuka-600 degrees. Kodwa-ke,{2}}insimbi ye-alloy ephezulu yezinga lokushisa (efana ne-H13, 310S) ingasebenza ngokuzinza kufika kuma-degree angu-1200, iqinisekisa ubuqotho besakhiwo se-grate.
Umphumela: Uma impahla ingamelani nezinga lokushisa eliphezulu, izokwenza ukuthi amapuleti e-grate agobe futhi abhajwe, ngaleyo ndlela kuthinte ukuhanjiswa kukadoti nokusebenza kahle kokusha.
Ukumelana nokugqwala
Umthelela: Amagesi agqwalayo afana ne-SO₂, HCl, ne-Cl₂ ku-flue gas azobhekana nokusabela kwamakhemikhali ebusweni be-grate, okuholela ekufakweni kwe-oxidation, ukugqwala kwe-pitting noma ukuqhekeka kokugqwala kwengcindezi.
Ikesi: Izinga lokugqwala lensimbi evamile engalungiswanga endaweni equkethe i-chlorine{0}}ingaba ngu-0.5 mm ngonyaka, kuyilapho izinga lokugqwala le-nickel{2}}elisekelwe kuma-alloys (njenge-Inconel 625) lingancishiswa libe ngu-0.01 mm ngonyaka.
Imiphumela: Ukugqwala kuzonciphisa isikhathi sokuphila kwe-grate, kukhuphule imvamisa yokuvala ukuze kulungiswe, futhi kuholele nasezingozini zokuphepha.
Ukwanda kokushisa kanye nokukhathala okushisayo
Umthelela: Uma i-grate ivama ukuqala-ukumisa ukusebenza noma ukuhluka kokulayisha, ukushintshashintsha kwezinga lokushisa kuzodala imijikelezo yengcindezi yokushisa, okungase kuholele ekuqhekekeni noma ekuxebukeni.
Icala: I-cast iron grate ine-coefficient ephansi yokwandisa okushisayo, kodwa i-brittle futhi ijwayele ukuqhekeka ngenxa yokushaqeka kokushisa; kuyilapho i-alloy steel forged (efana ne-16Mn) ingathuthukisa ukuqina kwayo ngokwelashwa okushisa futhi imelane nokukhathala okushisayo.
Umphumela: Ukukhathala okushisayo kuzonciphisa ukusebenza kokuvalwa kwe-grate, okuholela ekuvuzeni komoya noma ukusha okungalingani.
I-Thermal conductivity
Umthelela: I-grate idinga ukudlulisa ukushisa kungqimba lwemfucuza ukuze kube lula ukomisa nokuvutha. Izinto ezinokusebenza kahle kwe-thermal zingaholela ekushiseni okweqile kwendawo noma ukusha okubambezelekile.
Ikesi: I-thermal conductivity ye-alloy yethusi (cishe 400 W/m·K) iphinda izikhathi ezingu-8 kune-carbon steel (50 W/m·K). Ingakwazi ukuqhuba ukushisa ngokushesha nangokufana, kodwa izindleko ziphakeme kakhulu.
Ukuthuthukisa: Ngokuvamile, i-carbon steel substrate ihlanganiswa ne-surface coating (njenge-ceramic) ukuze kuzuzwe ibhalansi phakathi kwe-thermal conductivity kanye nokumelana nokugqwala.
Amandla omshini nokumelana nokugqoka
Umthelela: I-grate idinga ukuthwala isisindo semfucuza, amandla okuphusha, kanye nokudlidliza kwawo. Izinto ezisetshenziswayo ezingagugi kahle zizosheshisa ukuguga, okuholela ekwandeni kwezikhala, ukuvuza kwezinto ezibonakalayo noma ukuminyana.
Ikesi: Ukuqina -kwe-chromium cast iron (Cr26) ephezulu kufinyelela ku-HRC60, futhi ukumelana kwayo nokuguga kuphindwe kahlanu kunensimbi evamile. Ilungele ukucubungula imfucuza equkethe isihlabathi namatshe.
Umphumela: Ukugqoka nokudilika kuzonciphisa ukunemba kokunyakaza kwe-grate futhi kuthinte ukulawulwa komlilo.
