Boiler sludge yog ib qho kev tso nyiaj uas tsim thaum cov ntaub ntawv raug tshem tawm hauv cov dej boiler dawsrau, los yog ua raws li, kub boiler raj lossis lwm qhov chaw. Sludge tuaj yeem tsim los ntawm kev sib xyaw ua ke ntawm txhua yam khoom raug tshem tawm hauv dej, suav nrog cov khoom siv xoob xoob, cov ntxhia dej tsis sib haum thiab cov roj.
Cov nplai thiab sludges tsim li cas?
Yog nag lossis daus tshwm sim hauv daim ntawv xoob / slimy precipitate, nws yog hu ua sludge. Yog hais tias nag lossis daus tshwm sim nyob rau hauv daim ntawv ntawm ib qho nyuaj, adhering crust / txheej nyob rau hauv lub puab phab ntsa ntawm lub boiler, nws yog hu ua scale. Sludge: Nws yog mos, xoob thiab slimy precipitate tsim nyob rau hauv lub boiler.
Dab tsi yog sludge hauv boiler?
Tsuas yog dab tsi boiler sludge, koj nug? Qhov tseem ceeb, nws yog tsis muaj dab tsi ntau tshaj li qhov tso nyiaj pom hauv dej tsim hauv lub tank boiler dhau sijhawm. Cov deposits no tej zaum yuav muaj xws li minerals, roj, thiab lwm yam teeb meem. Sludge tuaj yeem lo rau ntawm phab ntsa ntawm lub boiler thiab txuas ntxiv loj tuaj nyob rau lub sijhawm, ua rau txhaws thiab lwm yam teeb meem.
Dab tsi yog qhov ua rau muaj cov kua dej sludge?
Cas. Sludge feem ntau yog tshwm sim los ntawm tsim tsis zoo lossis tsis zoo crankcase qhov cua, qis cav ua haujlwm kub, muaj dej hauv cov roj lossis crankshaft-induced cavitation, thiab tuaj yeem tsim nrog kev siv.
Boiler corrosion yog dab tsi?
Boilercorrosion yog kev puas tsuaj ntawm boiler hlau. Nws tshwm sim thaum cov pa oxygen hauv lub boiler dissolves rau hauv dej. Cov pa oxygen yaj tom qab ntawd ua rau cov tshuaj tiv thaiv nrog cov hlau nplua nuj (ferrous) boiler hlau hauv cov txheej txheem hu ua oxidation. Qhov tob thiab kab noj hniav tsim nyob rau hauv cov hlau.

Qhov twg yog qhov loj tshaj ntawm nqa tau tsim los ntawm aerofoil?
Ntawm lub hom phiaj dav dav aerofoil qhov loj tshaj plaws ntawm Lift tshwm sim rau saum npoo (qhov twg nws nkhaus tshaj plaws). Feem ntau hais txog 80% ntawm nqa tau tshwm sim ntawm lub tis saum npoo. Nqa yog proportional rau square ntawm airspeed.
Qhov twg tag nrho cov nqi hluav taws xob nyob ntawm qhov kev siv nyiaj siab tshaj plaws yog qhov twg?
marginal utility is zero. Tag nrho cov nqi hluav taws xob yog siab tshaj thaum marginal utility yog xoom. Qhov no yog vim muaj ntau txoj cai ntawm kev txo qis marginal utility uas hais tias tus neeg siv khoom noj ntau thiab ntau qhov zoo, qhov ntxiv rau tag nrho cov nqi hluav taws xob poob.
Qhov twg yog qhov kev sib raug zoo ntawm stereochemical ntawm ob khub ntawm cov molecules?
Enantiomers thiab diastereomers tsuas yog ob qho kev sib raug zoo stereochemical uas koj tuaj yeem muaj ntawm ob lub molecules. Cov stereoisomers yog ob lub molecules uas ua tiav ob qhov kev xav tau hauv qab no: Ob lub molecules yuav tsum muaj tib lub qauv molecular, thiab.
Thaum qhov kev ncua deb me me qhov twg ntawm qhov yuam kev hauv qab no tsis tsim nyog?
Thaum qhov kev ncua deb me me qhov twg ntawm qhov yuam kev hauv qab no tsis tsim nyog? Nqe lus piav qhia: Cov txiaj ntsig ntawm curvature yog txhawm rau nyeem cov pas nrig. Thaum qhov deb me me qhov yuam kev yog negligible. Qhov twg ntawm qhov yuam kev hauv qab no los ntawm tus kheej yuam kev?
Cov yeeb nkab condensate nyob qhov twg ntawm boiler?
Saib hauv qab lub boiler kom pom tias muaj cov yeeb nkab yas - Nws feem ntau yog dawb thiab nyob ib ncig ntawm 20mm (txog ¾ ") dav. Cov yeeb nkab yuav tsum khiav mus rau sab nraud ntawm koj lub tsev thiab yuav tsum khiav mus rau hauv qhov dej ntws.
