Mu rwego rwo gushakisha umusaruro usukuye, inganda z’amashanyarazi ziragenda zikoresha ikoranabuhanga rigezweho kugira ngo rigabanye ingaruka z’ibidukikije. Bumwe muri ubwo buryo bw'ikoranabuhanga ni ugukoresha sisitemu ya gazi ya desulfurizasi (FGD), igira uruhare runini mu kugabanya imyuka ihumanya ikirere. Intandaro yizi sisitemu ni FGD silicon carbide nozzles, ikozwe mubikoresho bigezweho bya ceramic bita silicon carbide. Iyi blog izasesengura akamaro kayo majwi, impinduka zishusho, ningaruka zabyo kubidukikije.
Silicon carbide nozzles yagenewe koroshya inzira ya desulfurizasi mumashanyarazi. Igikorwa cyabo cyibanze ni ugukuraho dioxyde de sulfure (SO2) hamwe n’indi myanda yangiza mu myuka y’imyuka isohoka mu gihe cyo gutwika ibicanwa by’ibinyabuzima, cyane cyane amakara. Akamaro k'iki gikorwa ntigashobora kuvugwa, kubera ko dioxyde de sulfure igira uruhare runini mu mvura ya aside no guhumanya ikirere, bishobora kugira ingaruka mbi ku buzima bw'abantu no ku bidukikije. Ukoresheje FGD silicon carbide nozzles, amashanyarazi arashobora kugabanya cyane imyuka ihumanya ikirere kandi yubahiriza amabwiriza akomeye y’ibidukikije.
Ibishushanyo bya FGD silicon karbide nozzles byateguwe kugirango bongere imikorere yabo mubikorwa bitandukanye. Ubwoko bubiri busanzwe bwa nozzle bukoreshwa muri sisitemu ya desulfurizasiya ni spiral yuzuye cone nozzle na vortex hollow cone nozzle. Umuzenguruko wuzuye wa cone nozzle wagenewe kubyara igihu cyiza cyamazi yinjira, cyongera umubano hagati yamazi na gaze ya flue, bityo bikongera imikorere yuburyo bwo gusohora. Ku rundi ruhande, vortex hollow cone nozzle, itanga uburyo bwo gusasa buzunguruka bukwirakwiza neza ibyinjira, bigatuma hafatwa neza gaze ya gaz. Guhitamo ubu bwoko bwa nozzle biterwa nibisabwa byihariye byuruganda rwamashanyarazi nibiranga gaze ya flue ivurwa.
Kimwe mu byiza byingenzi bya karubide ya silicon nkibikoresho bya FGD nozzle nigihe kirekire kandi kirwanya kwambara no kwangirika. Amashanyarazi akunze gukora mubihe bibi, hamwe nubushyuhe bwinshi hamwe nuduce duto duto tuboneka muri gaze ya flue. Silicon karbide nozzles irashobora kwihanganira ibi bidukikije bigoye, bigatuma ubuzima bumara igihe kirekire kandi bikagabanya amafaranga yo kubungabunga. Uku kuramba ntigutezimbere gusa imikorere ya desulfurizasi, ariko kandi bifasha kunoza ubwizerwe muri rusange bwibikorwa byamashanyarazi.
Usibye gutesha agaciro, nozzles ya FGD SiC nayo igira uruhare mukwanga no gukuraho ivumbi. Umwuka wa gazi uva mu mashanyarazi akoreshwa n’amakara ntabwo urimo dioxyde de sulfure gusa, ahubwo harimo na azote ya azote (NOx) hamwe n’ibintu byangiza. Muguhuza sisitemu ya FGD nubuhanga bwa denitrification, amashanyarazi arashobora kuvura icyarimwe icyarimwe, bikarushaho kunoza ikirere. Ubushobozi bwo gukemura ibyo byuka bitandukanye nibyingenzi kugirango huzuzwe ibipimo by’ibidukikije no kugabanya icyerekezo rusange cya karuboni y’umusaruro w’ingufu.
Ingaruka ku bidukikije yo gukoresha FGD silicon karbide nozzles iragera kure. Hatabayeho kwangiza no gutesha agaciro, imyuka ihumanya ikirere ituruka ku mashanyarazi irashobora gutera umwanda ukabije w’ikirere, bigatera indwara z’ubuhumekero no kwangiza ibidukikije. Byongeye kandi, imyuka idasukuye ituruka ku mashanyarazi akoreshwa n’amakara irashobora kwangiza ibice bishyushye bya turbine ya gaze muri sisitemu yikomatanya, biganisha ku gusana bihenze no gukora nabi. Mu gushora imari mu ikoranabuhanga ryateye imbere rya FGD, uruganda rw'amashanyarazi ntirushobora kurengera ibidukikije gusa, ahubwo rushobora no kunoza imikorere yarwo ndetse n’ubukungu bushoboka.
Mu gihe imiterere y’ingufu ku isi ikomeje kugenda itera imbere, hakenewe isoko y’ingufu zisukuye kandi zirambye ziragenda byihutirwa. FGD silicon karbide nozzles nigice cyingenzi cyinzibacyuho kubyara ingufu zicyatsi. Mugukuraho neza imyuka ihumanya yangiza imyuka ya flue, izo nogisi zifasha inganda zamashanyarazi kuzuza ibisabwa n'amategeko kandi zikagira uruhare mubumbe bwiza. Mu gihe ikoranabuhanga rigenda ritera imbere ndetse no gukenera kwita ku bidukikije bikomeje kwiyongera, uruhare rwa FGD silicon carbide nozzles mu kurwanya ihumana ry’ikirere n’imihindagurikire y’ikirere nta gushidikanya ko rizaba ingorabahizi.
Muri make, FGD Silicon Carbide Nozzle nudushya twinshi mubijyanye no gutunganya amashanyarazi. Igishushanyo cyacyo kidasanzwe, kiramba, ningirakamaro mugukuraho dioxyde de sulfure nindi myanda ihumanya bituma iba ikintu cyingenzi mugukurikirana umusaruro usukuye. Mugihe amashanyarazi akomeje gukoresha tekinoroji igezweho kugirango igabanye ingaruka z’ibidukikije, akamaro ka FGD Silicon Carbide Nozzles kaziyongera gusa, bigatanga inzira y’ejo hazaza heza.
