Nyob rau hauv lub boiler system, lub cyclone separator plays lub luag hauj lwm tseem ceeb. Nws tuaj yeem cais cov tshauv ya ya thiab cov pa roj carbon monoxide uas tsis tau hlawv tom qab cov roj combustion los ntawm cov pa roj flue. Txawm li cas los xij, qhov teeb meem ntawmrefractory castablentog tawm hauv lub tshuab hluav taws xob sib cais feem ntau tshwm sim, uas ua rau muaj teeb meem loj rau kev ua haujlwm ntawm lub boiler.Dab tsi yog vim li cas rau cov khoom siv refractory castable poob rau hauv cyclone separator?
Ua ntej, nws yog los ntawm thermal shock. Thaum pib thiab nres lub qhov cub lossis thaum lub load hloov pauv hnyav, qhov kub thiab txias hloov pauv yuav ua rau muaj kev poob siab tseem ceeb. Qhov kev hloov pauv kub sai no ua rau qhov kub thiab txias gradient nyob rau hauv thiab nyob rau saum npoo ntawm txheej refractory, uas nyob rau hauv lem induces loj thermal stress. Raws li qhov kev ntxhov siab txuas ntxiv mus ntxiv thiab hloov pauv, qhov saum npoo ntawm lub refractory castable yog nquag tawg, nws thiaj li ua rau cov khoom poob.
Qhov thib ob, nws yog los ntawm kev hloov pauv ntawm cov qauv. Thaum siv mus ntev, qhov sib xyaw thiab cov qauv siv lead ua theem ntawm cov ntaub ntawv refractory tuaj yeem hloov maj mam hloov. Cov kev hloov microstructural no yuav txo tau tag nrho lub zog ntawm cov khoom, ua rau deterioration ntawm deterioration thiab cracking nyob rau hauv lub me me kub kev nyuaj siab, ua rau poob.
Tsis tas li ntawd, mechanical kev nyuaj siab kuj yog ib qho tseem ceeb ua rau kom poob. Vim qhov sib txawv ntawm thermal expansion coefficient ntawm cov khoom siv refractory castable thiab cov hlau nkag mus rau hauv refractory hauv ob sab phlu, qhov expansion thiab contraction tus nqi ntawm ob yog inconsistent thaum kub hloov, ua rau mechanical stress. Qhov kev ntxhov siab no tuaj yeem ua rau kev sib raug zoo ntawm cov khoom siv refractory thiab cov hlau ua tsis tiav, thaum kawg ua rau detachment.
Tsis tas li ntawd, qhov teeb meem zoo ntawm lub refractory castable nws tus kheej tsis tuaj yeem tsis quav ntsej. Yog tias qhov sib xyaw ua ke thiab hmoov sib piv ntawm cov refractories castable yog tsis tsim nyog, los yog lub zog ntawm lub binder tsis txaus, nws cov kev ua tau zoo yuav raug cuam tshuam loj heev. Cov teeb meem zoo no yuav ua rau lub zog sib txuas ntawm cov khoom siv refractory castable kom tsis muaj zog thaum siv, thiab thaum kawg poob.
Nyob rau tib lub sijhawm, teeb meem thaum lub sijhawm tsim kho kuj yog ib qho tseem ceeb ua rau cov refractories castables poob. Yog tias qhov kev vibration tsis txaus thaum kev tsim kho lossis kev saib xyuas tsis txaus, lub zog sib txuas ntawm cov khoom siv refractory castable thiab sab hauv phab ntsa ntawm lub separator yuav raug cuam tshuam loj heev. Qhov kev tsim kho tsis zoo no yuav maj mam nthuav tawm thaum lub sijhawm ua haujlwm ntawm lub boiler, manifested raws li qhov poob ntawm refractory castables.
Thaum kawg, lub cev thiab tshuaj yaig thaum lub sijhawm ua haujlwm kuj yog ib qho laj thawj tseem ceeb rau cov khoom siv refractory castables. Qhov kub thiab kub ceev flue gas tsim thaum lub sij hawm boiler ua hauj lwm yuav ua rau tsis tu ncua yaig thiab hnav mus rau lub refractories castables. Nyob rau tib lub sijhawm, cov khoom siv tshuaj lom neeg hauv cov roj flue tuaj yeem cuam tshuam nrog cov refractories castable, ua rau nws cov qauv maj mam loosen, txo nws lub zog, thiab thaum kawg ua rau nws poob.
