Muaj ob yam tseem ceeb uas cuam tshuam rau qhov kub ntawm lub tshuab hluav taws xob: ib qho yog qhov hluav taws xob sab; lwm qhov yog lub qhov cub.
Lub ntsiab tseem ceeb cuam tshuam rau ntawm flue gas sab yog:1) Hloov cov khoom siv roj. 2) Kev hloov pauv ntawm huab cua ntim thiab kev faib tawm. 3) Kev hloov pauv ntawm cov hmoov tshauv ntawm cov cua sov. 4) Kev hloov pauv hauv qhov cub kub. 5) Kho qhov cub tsis zoo siab nyob rau hauv ib txwm muaj.
Lub ntsiab influencing yam ntawm lub chav sab yog:1) Kev hloov pauv hauv chav generator load. 2) Hloov nyob rau hauv saturated chav kub. 3) Kev hloov pauv ntawm cov dej kub.
Tsis muaj qhov tsis ntseeg tias lub tshuab hluav taws xob lub tshuab hluav taws xob chav ntsuas kub yog ib qho tseem ceeb rau kev nyab xeeb thiab kev lag luam ntawm lub tshuab hluav taws xob. Lub tshuab hluav taws xob qhov cub hluav taws xob ncaj qha cuam tshuam rau kev nyab xeeb thiab kev lag luam ntawm chav tsev. Kev kub siab ntau dhau tuaj yeem ua rau cov cua kub dhau los ua kom sov thiab tawg cov yeeb nkab, ua rau muaj kev ntxhov siab ntxiv hauv cov kav dej thiab qhov siab-siab ntawm chav turbine, yog li ua rau lub neej luv ntawm cov khoom siv. Ntawm qhov tod tes, qhov ntsuas kub tsawg dhau yuav txo qis kev lag luam ntawm chav tsev, thiab hauv qhov xwm txheej hnyav, dej yuav raug tsim tawm. cuam tshuam.
Cov yam ntxwv uas cuam tshuam rau qhov kub thiab txias ntawm chav generator feem ntau suav nrog peb yam hauv qab no:
1. Cov kev hloov hauv lub ntsiab chav siab
Kev cuam tshuam ntawm lub ntsiab chav siab ntawm superheated chav kub yog pom tau los ntawm kev faib tawm ntawm kev ua haujlwm nruab nrab enthalpy nce thiab kev hloov pauv ntawm chav tshwj xeeb thaum tshav kub kub. Qhov tshwj xeeb kub muaj peev xwm ntawm superheated chav yog heev cuam tshuam los ntawm lub siab. Qhov sib txawv ntawm qhov ntsuas kub ntawm qhov ntsuas kub thiab qhov kub thiab txias saturation nce ntawm qhov tsis tshua muaj siab, thiab tag nrho cov chav superheated Lub enthalpy nce yuav txo.
2. Kev cuam tshuam ntawm kev pub dej kub
Thaum cov dej kub tau qis dua, xws li thaum cua kub siab, thaum lub tshuab hluav taws xob tso zis tseem tsis hloov pauv, qhov ntsuas dej qis qis yuav ua rau muaj qhov nce ntawm cov roj, uas ua rau muaj kev nce hauv tag nrho cov radiant tshav kub. nyob rau hauv lub cub tawg thiab qhov kub thiab txias sib txawv ntawm lub qhov hluav taws xob qhov hluav taws xob cov pa taws thiab radiant overheating. Lub qhov cub kub ntawm qhov hluav taws xob ntawm lub convection superheater yuav nce; Ntawm qhov tod tes, qhov nce ntawm flue roj ntim thiab kub hloov pauv kub qhov sib txawv ntawm convection superheater yuav ua rau kom qhov hluav taws xob qhov cub kub. Qhov sib npaug ntawm ob qhov kev hloov pauv yuav ua rau lub zog superheated chav kub nce ntxiv. Qhov kev nce no muaj kev cuam tshuam ntau dua li tsuas yog nce lub nra ntawm lub tshuab hluav taws xob thaum ua kom cov dej kub tsis hloov pauv. Ntawm qhov tsis sib xws, thaum pub dej kub nce, qhov kub ntawm chav yuav txo.
3. Kev cuam tshuam ntawm qhov chaw nruab nrab ntawm cov nplaim taws
Raws li qhov chaw nruab nrab ntawm lub qhov cub hluav taws kub nce mus, lub qhov hluav taws xob hluav taws xob hluav taws xob yuav nce ntxiv. Txij li thaum tshav kub absorbed los ntawm radiant superheater thiab lub convection superheater nce thiab chav kub nce, cov nplaim taws qhov chaw muaj kev cuam tshuam zoo rau lub superheated chav kub.
Cov yam tseem ceeb uas cuam tshuam rau qhov reheat chav kub thiab superheat chav kub yog qhov zoo ib yam. Txawm li cas los xij, lub siab ntawm reheated chav yog tsawg thiab qhov nruab nrab chav kub yog siab. Yog li ntawd, nws lub peev xwm tshwj xeeb kub yog me dua li ntawm cov chav superheated. Yog li ntawd, thaum tib tus nqi ntawm cov chav tau txais tib lub tshav kub, qhov kub thiab txias hloov ntawm reheated chav yog loj dua li ntawm superheated chav. Nyob rau hauv luv luv, lub chav kub ntawm lub chav generator yog ib qho tseem ceeb nam ntawm lub lag luam, tab sis vim hais tias muaj ntau yam uas cuam tshuam rau lub chav kub kub, cov txheej txheem kev hloov yog nyuaj. Qhov no yuav tsum tau ua kom muaj kev hloov pauv ntawm chav sov yuav tsum tau soj ntsuam thiab soj ntsuam ntau zaus, thiab lub tswv yim ntawm kev hloov kho ua ntej yuav tsum tau tsim.
Thaum qhov kub thiab txias hloov, peb yuav tsum ntxiv dag zog rau kev saib xyuas thiab kev hloov pauv ntawm chav ntsuas kub, tshuaj xyuas kev sib raug zoo ntawm nws cov kev cuam tshuam thiab kev hloov pauv, thiab tshawb xyuas qee qhov kev paub hauv chav ntsuas kub hloov pauv los coj peb cov kev hloov kho.
