Thaum tshav kub kub poob ntawm biomass boiler

Thaum tshav kub kub poob ntawm biomass boiler

Lub tshav kub poob nyob rau hauv lub combustion ntawm biomass boiler yog tsuas yog lub tshav kub poob ntawm flue roj. Ib tug loj npaum li cas ntawm flue gas tshav kub yog tawm los ntawm lub chimney, thiab qhov poob ntawm volumetric tshav kub flue gas zoo heev txo lub biomass boiler.

s efficiency. Yog vim li cas rau lub tshav kub poob ntawm flue roj yog hais tias biomass roj muaj ib tug ntau ntawm noo noo, thiab cov biomass roj uas muaj cov ntsiab lus noo noo yuav tsum tau siv ib tug ntau dua kom qhuav kub.

Lub sijhawm ziab kom ntev dua yog txo cov dej noo. Qhov ntau dua cov dej noo, qhov qis calorific ntawm biomass.

Emissions ntawm cov pa phem los ntawm biomass boilers

Txawm hais tias biomass roj kuj yog huv si piv rau fossil fuels, SO2 roj thiab HCL roj tseem tuaj yeem saib xyuas hauv cov pa tso tawm tom qab combustion, thiab HCL.

Gas emissions yog ntau dua li cov thee combustion, uas yog vim muaj cov ntsiab lus chlorine siab nyob rau hauv biomass. Cov emissions yooj yim teb nrog cov poov tshuaj hauv biomass los ua aerosols,

Yog tias huab cua tsis zoo, lub flue gas purifier tuaj yeem muab ntxiv rau hauv qhov chaw nres nkoj kom txo cov pa phem.

Slagging ntawm biomass boiler

Ib qho teeb meem loj dua hauv biomass-hluav taws kub boilers yog qhov teeb meem ntawm slagging. Thaum slagging tshwm sim, nws yuav cuam tshuam rau qhov txaus ntawm cov roj combustion thiab txo thermal efficiency.

tus nqi. Tshwj xeeb tshaj yog nyob rau hauv fluidized txaj combustion hom, alkaline hais (tsuas yog sodium thiab poov tshuaj) nyob rau hauv biomass react nrog quartz xuab zeb nyob rau hauv lub txaj cov ntaub ntawv los tsim ib tug tsawg-kub eutectic sib tov.

Nws adheres rau saum npoo ntawm xuab zeb thiab cov ntaub ntawv slagging. Yog li ntawd, nws yog ib qho tsim nyog yuav tau ntxiv inert additives rau lub txaj khoom kom txo tau qhov tsim ntawm slagging.

Biomass boiler paug thiab corrosion

Lub biomass boilers tam sim no nyob rau hauv kev ua lag luam muaj teeb meem ntawm tshauv nyob rau hauv lub rhuab cheeb tsam, slagging thiab paug ntawm lub superheater. Fouling feem ntau yog vim qhov tseeb tias biomass muaj ntau cov tshuaj alkaline

Nyob rau hauv qhov kub-kub combustion ib puag ncig, alkaline tshuaj yog heev yooj yim rau tsim slag nyob rau hauv lub cub tawg nrog rau cov inorganic ntsiab lus los yog ua raws li lub rhuab nto nyob rau hauv daim ntawv ntawm chav thiab ya tshauv hais, uas yuav cuam tshuam.

Lub thermal efficiency ntawm lub boiler, thiab txawm nyob rau hauv lub zos tshav kub hloov qhov chaw yuav raug them los ntawm kev sib kis thiab poob tshav kub kev ua tau zoo. Zoo li cov thee hluav taws xob boilers, biomass boilers kuj muaj teeb meem corrosion, uas zoo ib yam li cov thee-tua boilers.

Qhov sib txawv ntawm cov boilers yog qhov corrosion ntawm biomass boilers feem ntau yog chlorine corrosion, thiab tus nqi corrosion nce nrog qhov nce ntawm chav kub. Qhov chaw uas corrosion tshwm sim feem ntau yog nyob rau saum npoo ntawm lub superheater.
