Boiler Grate Bar

Boiler Grate Bar

Pub grate yog nyob rau hauv qab ntawm lub chute, thiab tag nrho qhov dav ntawm cov khoom noj grate yog 5100mm, los xyuas kom meej qhov ntau thiab uniformly xa cov khib nyiab mus rau incineration grate. Txhua qhov pub grate yog nruab nrog peb hydraulic feed push rods los thawb cov khib nyiab mus rau hauv lub incinerator los ntawm lub feed push rods. Lub tshuab nqus tsev twj yog hydraulically tsav, thiab lub tog raj kheej hydraulic yog powered los ntawm qhov chaw nres tsheb hydraulic. Kev pub mis muaj xws li kev nrawm nrawm nrawm thiab pub mis qeeb, ua raws li kev rov qab sai. Qhov ceev ntawm txhua qhov kev txav txav tuaj yeem hloov kho los ntawm kev tswj hwm, thiab qhov ceev thiab kev ncua deb ntawm lub laub tuaj yeem teem rau hauv lub computer hauv chav tswj nruab nrab. Lub tog raj kheej hydraulic yog mounted nyob rau hauv ib tug tag nrho enclosed plua plav npog.

 

Incineration grate los ntawm cov grate ruaj khov, zawv zawg grate thiab tig grate peb hom grate, tshwj xeeb tig grate tsim ua grate tsis tsuas yog muaj lub zog reciprocating ib txwm ua haujlwm, tab sis kuj muaj txoj haujlwm tig, ntxiv dag zog rau cov khib nyiab sib xyaw, xoob, qhov cua, qis calorific. tus nqi, cov yam ntxwv siab noo noo ntawm khib nyiab incineration muaj qee qhov zoo, ua rau slag kub txo tus nqi tswj hauv<3%.

 

Tag nrho cov incinerator grate muab faib ua tsib grate cheeb tsam pawg. Txhua pawg grate tus qauv suav nrog ob lub zawv zawg grate, ob txoj hlua tig thiab ob lub grate ruaj khov, thiab rau lub tog raj kheej hydraulic kom ua tiav qhov kev txav thiab tig ntawm cov khib nyiab. Daim ntawv zawv zawg grate txav horizontally los xyuas kom meej tias cov khib nyiab combustion txheej txav mus rau pem hauv ntej ntawm txoj kab rov tav thiab txav mus rau pem hauv ntej kom ntseeg tau tias cov khib nyiab txheej txav mus. Qhov ceev thiab zaus ntawm txhua pab pawg ntawm cov cub tawg tuaj yeem tswj tau nyias, uas txhim kho kev hloov pauv ntawm lub incinerator rau cov khib nyiab hauv tsev nrog ntau yam ntawm cov nqi calorific hloov pauv. Tsis tas li ntawd, kev ua haujlwm tuaj yeem nres tag nrho thaum tsim nyog, thiab cov txheej txheem ntawm kev ziab, cua sov, decomposition, hlawv thiab hlawv cov khib nyiab ntawm qhov cub incineration tuaj yeem tswj tau zoo dua. Nyob rau hauv lub incineration ntawm cov khib nyiab nrog high calorific nqi, qhov piv ntawm tig thiab zawv zawg lub sij hawm yog preset nyob rau hauv lub tswj system kom txo tau qhov zaus ntawm txhua pab pawg neeg ntawm tig lub cub tawg grate, thiab txo lub sij hawm nyob rau hauv cov khib nyiab ntawm cov khib nyiab grate, yog li ntawd. los xyuas kom meej cov khib nyiab kho los ntawm lub incinerator.

 

Qhov dav ntawm lub grate yog 300 hli, nrog 17 grate kab, thiab tag nrho qhov dav ntawm cov grate yog 5100 hli. Tag nrho qhov ntev ntawm lub qhov cub hluav taws xob yog 10.487 m, thawj plaub chav nyob yog qhov hluav taws kub, thiab chav kawg yog qhov chaw hlawv. Txhawm rau kom ntseeg tau tias qhov ua tiav thiab tag nrho incineration ntawm cov khib nyiab, thermal txo tus nqi ntawm lub incinerator yog tswj ntawm<3%, so as to meet the relatively strict technical requirements, so the last section should be appropriately lengthened.

 

Cov cua nkag ntawm lub hauv qab ntawm lub grate chamber optimizes combustion cua mov thiab ncua lub neej kev pab cuam ntawm lub grate. Lub thoob tshauv ntawm qhov qis ntawm lub grate tuaj yeem tsis tsuas yog sau cov tshauv nyob rau hauv qab ntawm lub cub tawg, tab sis kuj yog thawj cua nkag ntawm txhua pawg grate. Thawj cov huab cua nkag mus rau hauv lub incinerator nrog cov grate pawg thiab tshuab mus rau cov khoom khib nyiab txheej, uas tsis tsuas yog txo cov coking ntawm cov khib nyiab nto, tab sis kuj cools lub grate daim ntawv zoo thiab txo tus nqi ntawm cov grate. Tsis tas li ntawd, cov grate xaiv ntawm cov ntaub ntawv zoo, nrog rau kev sib koom ua ke ntawm txhua qhov txav mus los, cov grate piece muaj qhov ua haujlwm siab.

 

Lub grate sawb feem ntau yog ua los ntawm cov khoom siv superalloy thiab muaj qhov hnav tsis zoo thiab kub tsis kam. Cov khoom siv no tuaj yeem tswj kev ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias ib puag ncig, thaum tuaj yeem tiv taus cov khoom siv hauv qhov cub thiab corrosion ntawm cov roj kub kub. Lub grate sawb feem ntau yog tsim los nrog cov qauv tshwj xeeb los txhim kho nws cov hnav tsis kam thiab txuas ntxiv nws lub neej kev pab cuam.

 

Lub ating sawb yog ib qho tseem ceeb ntawm lub tshuab sintering, uas yog siv los txhawb sintering ore nyob rau hauv qhov kub thiab txias ib puag ncig kom ntseeg tau cov txheej txheem sintering du. Nws cov ntaub ntawv thiab cov txheej txheem ntau lawm muaj kev cuam tshuam tseem ceeb ntawm kev ua haujlwm thiab lub neej ntawm sintering tshuab.

 

 

Cov khoom siv grate sawb yuav tsum ruaj khov kho tshuab thiab tshuaj lom neeg nyob rau hauv qhov kub thiab txias. Tam sim no, cov khoom siv grate sawb feem ntau suav nrog siab chromium alloy steel, siab aluminium alloy steel, siab silicon alloy steel thiab cam khwb cia hlau.

 

1. High-chromium alloy hlau

High chromium alloy steel yog ib hom hlau nrog chromium ua lub ntsiab alloy, nrog rau qhov kub thiab txias tsis kam, oxidation kuj thiab corrosion kuj. Nws lub ntsiab tsis zoo yog lub siab hardness, yooj yim rau qaug zog cracking. Feem ntau siv high-chromium alloy steel muaj 12Cr1MoV, 15 CrMo, thiab lwm yam.

 

2. High-qib aluminium alloy steel

High aluminium alloy steel yog ib hom hlau nrog txhuas ua lub ntsiab alloy, nrog rau qhov kub thiab txias tsis kam, oxidation kuj thiab corrosion kuj. Piv nrog rau siab chromium alloy steel, nws muaj qis hardness tab sis zoo dua toughness. Feem ntau siv high aluminium alloy steel muaj 1 Cr 5 Mo, 3Cr5MoV, thiab lwm yam.

 

3. High-silicon alloy hlau

High silicon alloy steel yog ib hom hlau nrog silicon ua lub ntsiab hlau alloy, nrog zoo kub tsis kam, oxidation kuj thiab corrosion kuj. Nws lub ntsiab tsis zoo yog qhov yooj yim ntawm kev tawg. Feem ntau siv siab silicon alloy steel muaj 20SiMn2MoV, 35SiMn2MoV, thiab lwm yam.

 

4. Cam khwb cia hlau

Cam khwb cia hlau yog ib qho pheej yig thiab yooj yim rau txheej txheem cov khoom uas feem ntau siv rau me me ntawm cov tshuab sintering. Tab sis nws qhov kub thiab txias tsis kam thiab corrosion kuj tsis zoo, yooj yim tawg hauv qhov kub thiab txias. Nyob rau hauv lub grate sawb, cov cam khwb cia hlau feem ntau yog siv los txhawb qhov me me ntawm lub tshuab sintering, xws li lub log ncej.

 

 

Cov txheej txheem ntau lawm ntawm grate sawb feem ntau suav nrog forging, casting thiab vuam.

1. Forge

Forging yog ib txoj hauv kev ua kom sov cov ntaub ntawv hlau mus rau qhov kub thiab txias thiab tom qab ntawd hloov lawv cov duab thiab kev ua haujlwm los ntawm kev nias thiab cuam tshuam. Lub forged grate sawb muaj cov khoom siv zoo thiab kub ua haujlwm, tab sis tus nqi kuj yog siab heev. Cov txheej txheem forging muaj xws li dawb forging, dov forging, nplhaib forging thiab lwm yam.

 

2. Casting

Casting yog txoj kev ua tiav ntawm cov khoom siv hlau tom qab cua sov thiab nchuav rau hauv pwm, txias thiab tau txais cov duab thiab qhov loj me. Tus nqi ntawm casting grate sawb yog tsawg, tab sis nws cov kub tsis kam thiab corrosion kuj tsis zoo. Cov txheej txheem casting feem ntau suav nrog xuab zeb casting, precision casting, tuag casting, thiab lwm yam.

 

3. Vuam

Vuam yog ib txoj hauv kev ua kom cua sov ob lossis ntau dua cov ntaub ntawv hlau mus rau qhov chaw melting los ntawm qhov chaw tshav kub kom fuse lawv ua ke. Cov welded grate sawb tus nqi qis, tab sis nws lub zog thiab kub tsis kam yog qhov tsis zoo. Cov txheej txheem welding feem ntau suav nrog arc vuam, argon arc vuam, submerged arc vuam thiab lwm yam.

 

Cov khoom siv thiab kev tsim khoom ntawm grate sawb ncaj qha cuam tshuam rau kev ua haujlwm thiab lub neej ntawm lub tshuab sintering. Thaum xaiv cov khoom siv grate thiab cov txheej txheem ntau lawm, nws yuav tsum tau ua raws li qhov xwm txheej tshwj xeeb thiab siv cov kev xav tau ntawm sintering tshuab los xyuas kom meej qhov kev ua haujlwm ntawm sintering tshuab.
