Cov ntaub ntawv rwb thaiv tsev thermal rau cov pa roj convection ntawm cov cua sov pov tseg boiler 2

Qhov teeb meem no peb yuav txuas ntxiv qhia txog cov khoom siv rwb thaiv tsev uas tau tsim.

Cov khoom siv pob zeb wool: feem ntau siv pob zeb wool rwb thaiv tsev board, nrog rau cov khoom hauv qab no: qhov ceev: 120kg / m3; Qhov kub siab tshaj plaws ua haujlwm: 600 ℃; Thaum qhov ceev yog 120kg / m3 thiab qhov kub nruab nrab yog 70 ℃, qhov thermal conductivity tsis pub ntau tshaj 0.046W / (m · k).
Cov khoom siv aluminium silicate refractory fibersr thiab cov khoom siv aluminium silicate refractory fibers felt: Cov khoom siv aluminium silicate refractory fiber thiab cov khoom siv aluminium silicate refractory fiber felt yog ib hom khoom siv refractory thiab rwb thaiv tsev tshiab. Nws yog cov khoom siv inorganic uas feem ntau yog tsim los ntawm Al2O3 thiab SiO2, tseem hu ua ceramic fiber. Nws muaj kev tiv thaiv hluav taws kub thiab kev ua haujlwm rwb thaiv tsev zoo. Tam sim no, ntau lub tuam txhab tsim boiler siv cov khoom siv aluminium silicate refractory fibers thiab cov khoom lag luam ua cov khoom sau rau cov pob qij txha nthuav dav thiab lwm qhov, hloov cov khoom siv xws li asbestos thiab lwm yam khoom.
Cov khoom ntawmCov fibers refractory aluminium silicatethiab lawv cov khoom yog raws li nram no: qhov ceev ntawm cov khoom yog li 150kg / m3; Qhov ceev ntawm cov fibers yog kwv yees li (70-90) kg / m3; Qhov hluav taws tsis kam yog ≥ 1760 ℃, qhov kub siab tshaj plaws ua haujlwm yog li 1260 ℃, thiab qhov kub ua haujlwm ntev yog 1050 ℃; Thaum qhov ceev yog 200kg / m3 thiab qhov kub ua haujlwm yog 900 ℃, qhov thermal conductivity ntawm cov fibers thiab cov khoom yuav tsum tsis pub tshaj 0.128W / (m · k).
