Dab tsi yog cov yam ntxwv ntawm finned tube technology

Cov qauv duab kos duab ntawm kauv finned tube qhia cov yam ntxwv hauv qab no ntawm cov cua sov saum npoo nrog kauv finned raj raws li cov khoom sib pauv cua sov:

(1) Ua kom lub tshav kub hloov mus rau sab nraud ntawm lub raj, cov kauv finned raj nthuav dav qhov chaw hloov hluav taws xob sab nraum lub raj. Thaum qhov ntev ntawm sab nraud yog tib yam, nws qhov chaw hloov hluav taws xob yog ob peb zaug lossis txawm tias kaum ob ntawm lub sijhawm ntawm cov hlab ntsha liab qab, txhim kho lub peev xwm hloov hluav taws xob thiab kev hloov hluav taws xob ntawm sab nraud ntawm lub raj.

(2) Lub compact qauv ntawm cov cua sov saum npoo ntawm cov kauv finned tube nras tsub kom lub tshav kub hloov mus rau ib chav tsev ntim, uas yuav txo tau lub ntim ntawm cov cua sov nto nyob rau hauv tib lub tshav kub hloov chaw.

(3) Txo qhov hnav ntawm cov cua sov saum npoo vim qhov hloov pauv tau zoo dua ntawm cov cua sov saum npoo ntawm cov kauv finned raj tuaj yeem txo qhov nrawm ntawm cov kua dej tawm sab nraud, yog li txo qhov hnav ntawm cov cua sov saum npoo. Vim hais tias cov yam ntxwv hais saum toj no ntawm kauv finned tube bundles, cov khoom siv hluav taws xob sib pauv siv lawv li cov khoom siv hluav taws xob sib txuas muaj qhov zoo ntawm cov qauv compact, tsis tshua muaj hlau noj, thiab cov nqi khiav lag luam tsawg. Yog li ntawd, lawv tuaj yeem siv rau hauv kev lag luam, tubular cua preheaters, convective evaporation cua sov qhov chaw ntawm boilers, nrog rau cov khoom sib pauv cua sov hauv metallurgical thiab tshuaj tshuab.

Kauv finned raj tau siv rau boiler economizers nyob rau txawv teb chaws thaum ntxov li 1960s. Txhawm rau txo cov pa luam yeeb hauv cov hluav taws kub tshauv hluav taws kub boilers thiab ua tiav lub hom phiaj ntawm kev txo qhov hnav ntawm cov neeg lag luam, cov qub Soviet Union, raws li kev tshawb fawb, tau hloov pauv ntau lub boilers siv kauv finned raj economizers.

Tus nqi them rau cov raj finned feem ntau suav nrog ob lub taub hau ncaj qha, ob lub luj tshib, thiab PVC cov kav dej kub nrog rau sab sauv thiab sab hauv dej tawm ntawm 1 meter txhua. Tsuas yog rau cov khoom siv no, cov yeeb nkab txuas ntxiv yuav tsum tau ua thaum lub sijhawm teeb tsa vim qhov tshwj xeeb yuav tsum tau ntawm Circuit Court yuav raug them cais. Hom finned hlab tag nrho muaj cov npe nqi uas txhua tus neeg yuav tsum tuaj yeem pom ua ntej, thiab cov neeg ua haujlwm yuav tsum tsis txhob raug tso cai kom them tus nqi ntau dhau.
