Cov yam ntxwv ntawm biomass boilers

1. Kev ruaj ntseg thiab kev siv hluav taws xob tsawg
Biomass boilers yog fueled los ntawm kev ua liaj ua teb thiab hav zoov pov tseg (xws li straw, ntoo chips, mov husks) los yog tshwj xeeb biomass pellets, uas yog dav siv thiab rov ua dua tshiab, thiab muaj txiaj ntsig zoo dua cov roj fossil (coal, roj, roj). Ua raws li kev lag luam hauv xyoo 2023 ua piv txwv, tus nqi ntawm biomass pellet roj yog kwv yees li 800-1200 yuan / ton, thaum tus nqi ntawm cov thee feem ntau yog nyob nruab nrab ntawm 1200-2000 yuan / ton, thiab cov tshauv tom qab combustion ntawm biomass roj tuaj yeem rov ua dua li cov organic chiv kom txo tau tus nqi ntxiv. Tsis tas li ntawd, biomass boilers muaj cov roj hloov tau zoo, uas tuaj yeem txo qhov kev pheej hmoo ntawm kev cuam tshuam kev lag luam vim cov roj hloov pauv los ntawm kev kho cov roj burner kom haum rau biomass fuels nrog ntau qhov sib txawv thiab cov nqi calorific.

2. Qhov zoo tshaj plaws ntawm kev ua haujlwm ib puag ncig
Qhov emission Performance index ntawm biomass boilers yog qhov zoo dua li cov thee tsoos - raug rho tawm haujlwm boilers. Piv txwv li, SO₂ emissions tuaj yeem tswj tau qis dua 30mg / m³ (feem ntau yog 200-500mg/m³ rau cov thee-tua boilers), thiab NOx emissions tsawg dua 150mg/m³, uas ua tau raws li cov kev txwv emission txwv ntawm thaj chaw tseem ceeb hauv lub tebchaws "Boiler Standard" 13271{11}}2014). Nyob rau tib lub sijhawm, carbon dioxide (CO₂) tsim los ntawm biomass combustion belongs rau qeb ntawm cov pa roj carbon monoxide, thiab nws cov net emissions yog ze rau xoom, pab cov lag luam ua tiav cov hom phiaj ntawm cov pa roj carbon monoxide. Qee cov qauv high-end kuj tau nruab nrog lub hnab los yog cov dej ntub dej electrostatic nag lossis daus, uas tuaj yeem txo cov teeb meem me me (PM) emissions tsawg dua 10mg / m³ kom tau raws li qhov yuav tsum tau ua kom qis qis.

3. Kev khiav hauj lwm efficiency thiab thermal stability
Niaj hnub nimno biomass boilers txais txheej txheej combustion los yog fluidized txaj combustion tshuab, nrog ntse tswj system, uas yuav ua tau kom raug roj thiab huab cua piv, thiab cov thermal efficiency feem ntau mus txog 85% -92%. Piv txwv li, 10-tuj biomass boiler tuaj yeem ua tiav qhov thermal efficiency ntawm 90% thaum ua haujlwm ntawm qhov muaj peev xwm, uas yog 10%-15% siab dua li ntawm cov tsoos thee hluav taws xob boilers. Qhov kub tsis sib xws ntawm lub cub tawg yog qhov zoo dua li cov thee hluav taws xob boilers, thiab qhov kub sib txawv yog tswj nyob rau hauv ± 20 degree, uas zoo txo ​​cov khoom poob los ntawm lub zos overheating. Tsis tas li ntawd, biomass boiler muaj qhov pib-nres nrawm nrawm, tsuas yog siv 30-60 feeb kom khiav los ntawm qhov txias mus rau tag nrho cov load, ua rau nws tsim nyog rau cov xwm txheej cua sov uas yuav tsum tau siv lub ncov shaving.

4. Ntau yam ntawm daim ntawv thov scenarios
Lub peev txheej ntawm kev siv biomass boilers suav nrog kev tsim khoom, kev lag luam cua sov thiab pej xeem kev lag luam. Hauv kev lag luam, nws tuaj yeem muab chav lossis dej kub rau kev ua zaub mov, textile printing thiab dyeing, tshuaj thiab tshuaj industries, hloov cov tsoos thee - raug rho tawm haujlwm boilers kom txo cov nqi tiv thaiv ib puag ncig; Hauv kev lag luam, tsev so, tsev kawm ntawv, tsev kho mob thiab lwm qhov chaw tuaj yeem ua tiav cov cua sov hauv nruab nrab lossis dej kub los ntawm biomass boilers, thiab ib qho khoom siv tuaj yeem ua tau raws li qhov xav tau cua sov ntawm cov tsev ntawm 10,000-50,000 square meters; Rau kev siv pej xeem, me me biomass boilers (xws li 100-500kW) tuaj yeem siv rau kev faib cov cua sov hauv cov chaw nyob deb nroog, thiab tuaj yeem siv nrog lub zog cia tso tsheb hlau luam kom ua tiav 24-teev cua sov tas li. Nws yog ib nqi sau cia hais tias biomass boilers yog rhiab heev rau roj cov ntsiab lus ntawm noo noo (pom zoo yuav tsum tau tswj ntawm 15% -25%) thiab yuav tsum tau nruab nrog cov khoom ziab los yog xaiv cov roj pellet tiav kom ruaj khov.
