DT taxane ah bamka nadiifinta
Dulmarka wax soo saarka:
Qaybaha xaddidaya bamka waxay qaataan tignoolajiyada jilitaanka socodka horumarsan si loo dammaanad qaado naqshadaynta bamka la isku halayn karo iyo hufnaanta sare ee hawlgalka.
Qalabka ka hortagga daxalka & birta iyo caagagga kuwaas oo si gaar ah loogu farsameeyay matoorada FGD ayaa lagu caddeeyay hab-dhaqanka in ay hubin karaan shaqada matoorka cimriga dheer. Iyada oo la hagaajinayo qaybaha dhalista si loo beddelo booska impeller ee qolka bamka oo dhan-waqtiga hawlgalka waxtarka sare leh ee bamka ayaa la gaari karaa. Bamka waxaa lagu gartaa qaab-dhismeedka dhabarka dhabarka kaas oo fudud oo horumarsan.
Way fududahay in la dayactiro lana hagaajiyo waxayna u baahan tahay inay burburiso tubooyinka biyaha soo gala iyo kuwa ka baxa. Shaabadda makaanikada weelka lagu shubay ee si gaar ah loogu isticmaalo habka nadiifinta waa la qaatay oo hawlgalkeedu waa la isku halayn karaa
Astaamaha ugu muhiimsan:
a) Qaybaha qoyan waxay qaataan falanqaynta jilitaanka socodka sare ee habka naqshadeynta si loo dammaanad qaado waxqabadka la isku halayn karo, waxtarka sare ee bambooyinku. Macmiilku waxa uu bamka ka dhigi karaa in uu mar walba ku shaqeeyo xaalad hawleed oo hufan isaga oo hagaajinaya qaybaha xajinta ee matoorka bamka si uu ugu habboonaado booska dalool ee bamka.
b) Bambooyinku waxa lagu nashqadeeyey hab-dhismeedka dib-u-ururinta. Waxaa lagu soo bandhigay qaab-dhismeed fudud oo ay fududahay in la dayactiro iyada oo aan la burburin tuubada soo gelista iyo tan ka baxda bamka. Dhabarka dhamaadka waxa uu qaataa rullaluistuyada duuban ee dibadda laga keeno iyo dhamaadka wadista waxa ay isticmaashaa laba rullaluistemadka silindrical ah oo leh saliid khafiif ah. Waxay kor u qaadi kartaa timaha ?? xaaladda shaqada si loo dheereeyo nolosha adeegga ee biraha.
c) shaabadda makaanikada waxaa loo qaabeeyey iyadoo loo eegayo qaabka qaab dhismeedka bamka desulphurization, dabeecadda slurry iyo dabeecadda codsiga. Waa shaabad farsamo oo kartoon ah. Waxay leedahay waxqabad wanaagsan, nolol adeeg oo dheer.
d) Qalabka FGD (Flue Gas Desulfurization) ee matoorku waxa uu ka samaysan yahay nooc cusub oo ah walxo Cr30 duplex ah oo aan bir lahayn oo ay si gaar ah u soo saartay shirkadeena lafteeda. Walaxda cusub waxay leedahay wax qabad muuqda oo u adkaysta daxalka iyo xirashada. Bamka, daboolka bamka iyo taarikada ka go'an waa qaybo cadaadis ah waxayna ka samaysan yihiin birta shubka ah. Daboolka wax-soo-saarka iyo daboolka nuugiddu wuxuu ka samaysan yahay Cr30 bir cad oo aan laba waji lahayn. Maaddada xadhkaha daboolka ah ee daboolka, xargaha xargaha, iyo daaha dambe waa caag dabiici ah oo leh waxqabad dabiici ah oo jilicsan, miisaan fudud, qiimo jaban.
Isticmaalka ugu muhiimsan:
Waxaa inta badan laga codsadaa in warshadda korontada ee bamka wareegga munaaradda nuugista si ay u gudbiyaan slurry.Power warshad daxalka ah, warshad birta for desulphurization gaaska flue.
