BFB Boiler (Bubbling Fluidised Mubhedha Boiler) inonyanya kuve diki uye yepakati-yakaenzana maindasitiri emuindasitiri. Iyo ine yakanakira kupfuura cfb boiler (kutenderera kwemvura yemubhedha bilebr biiler) paunenge uchipisa biomass uye mamwe marara. Biomass pellet mafuta haina kuoma kuwanikidza, iyo inogona kusangana kwenguva yakareba kushanda kwezvinhu zvidiki-zvidiki zveBiomass maindasitiri. Iyo mafuta ndeye biomass pellets, kunyanya huni chip yakasanganiswa neyekumanikidza ekurima uye masango zvirimwa zvigunwe.

BFB Boiler Chimiro Dhizaini

1. Yese chimiro

Iyi bfb boiler ndeyechirume inotenderera yemvura inobiridzira, ine madhiri maviri akarongwa akatwasuka. Nzvimbo huru yekudziya ndeye madziro emvura, flue duct, convection tube bundle, economizer uye yekutanga & yekirasi yemhepo preheater. Chidzitiro chinobvumidza zvakamiswa chimiro, chakakomberedzwa nemadziro emvura emvura.

Chimiro chinotora zvese-simbi chimiro, 7-degree degredquakedque yakakura uye inogara chimiro chekugadzira. Mativi ese ari papuratifomu uye manera ekushanda uye kugadzirisa.

Iyo BFB Boiler inoshandisa pasi-mubhedha inopisa flue gasi gasi rekutsamwa, uye mweya wekusununguka wakakamurwa kuva mhepo yekutanga uye yechipiri mweya. Iyo kugoverwa kuwanda kwemhepo yekutanga uye sekondari ndeye 7: 3.

2. Kukanganisa system uye flue gasi kuyerera

2.1 Ignition uye Mhepo Distribution mudziyo

Iyo densitiya mafuta ndeye mafuta echando. Paunenge uchisiya uye kutanga boiler, tembiricha yemweya unopisa mumhepo inotonhorera yemvura ichave yakanyatso kudzorwa kuti ive nechokwadi chekuti haina kupfuura 800 ° C kudzivirira hood. Chivakwa chemvura chine mvura chakaumbwa chemvura yemadziro emadziro emadziro emadziro emadziro emadziro emadziro uye madziro emvura. Chikamu chepamusoro chekamuri yemvura inodonhedzwa nemvura ine mushauriti

2.2 Chidzikiso Chomoto Combustion

Chikamu chemuchinjiko chemadziro emvura chiri rectangular, nzvimbo yemuchinjiko-chikamu, chira, chengetedza chibaya chiri 9m, uye nzvimbo inoshanda yemhepo yekuparadzira yemhepo ndi '8m2. Kumusoro kwechoto is pamberi pemvura madziro emvura. Ruoko rwevira rwuri pamusoro pechikamu chepamusoro chemadziro emvura emvura, nekureba kweanenge 1.5m.

3 Steam-mvura kutenderera

Mvura yekudyisa inopinda muhupfumi mumuswe flue duct uye wozoyerera muchitokisi chepamusoro. Mvura yemubhoti inopinda mumusoro wezasi kuburikidza nekuparadzaniswa pasi, inoyerera kuburikidza nemapurazi emvura emvura uye anodzokera kuguruva repamusoro. Wall yakavharika machubhu pamativi ese ari maviri akabatana neyekumusoro uye pasi zvigubhu kuburikidza nemisoro. Iyo convection tube bundle inosungirirwa kune yepamusoro uye yepazasi zvigubhu.
