Recrocal grate boiler izita rimwe zita rekudzokorora grate boiler. SeBiomass Boiler, Recrocal Grate Boiler yakakodzera kupisa guruva, huswa, bagasse, muchindwe fiber, mupunga hushoma. Biomass mafuta emafuta anovandudza mafuta, ayo ane sarufa asingasviki uye eshangu, pamwe zvishoma saka2 uye guruva rekubuda.
Kune marudzi mazhinji ezvekuti biomass mafuta, kusanganisira pellet mhando, rudzi rweproquetette uye mhando yakawanda. Tsvina kubva mudondo rekugadzira huni, senge bark uye sawdust, rinowanzoshandiswa mumhando yehuwandu. Nekudaro, iyo unyoro hwe marara ndeye 50% kana kupfuura, uye kukosha kweCalorific kwakaderera kwazvo. Saka zvakaoma kupisa zvinobudirira neanowanzoita biomass boiler. Naizvozvo, takagadzira yakasanganiswa yekudzokorora grate boiler ine akasiyana ekuda angles. Bhutsu nyowani yeBiomass inogona kuenderana nekurohwa kwezvinhu zvakadai biomass mafuta ane yakanyanya kunyorova uye yakadzika yekudziya kukosha.
1.Destsign Fuel
Uku kudzoreredza grate boiler kunogadzirwa zvakanyatsogadzirirwa danda rekugadzirisa huni. Mushandisi anoda kupisa 200Tons makondo marara pazuva kuti aumbe 1.25mpa yakawedzerwa steam yekugadzira maitiro. Iko kuongororwa kwechikamu kunokonzeresa dondo renje iri seinotevera:

3. Chimiro chakazara
Iyo Recrocal Grate Boils inogamuchira kaviri-Drum yakatwasuka kutenderera kwekutenderera mhepo yekuvhuvhuta, uye choto chakadzika chinotsigirwa uye chepamusoro chakasungirirwa.
Kufunga nezve yakakwira kunyorova uye yakaderera CALLIFITIC
Iyo danda boiler inogamuchira imwe-layer chimiro. Iyo slag remover iri pazasi pe 0-metres kukwirira, uye iyo layer layer iri pa 0-metres kukwirira. Iyo system system iri nyore, iyo inochengetedza mutengo wehurumende kusvika pakukura kukuru.
4. Dhizaini Pfungwa
4.1 Compustion mudziyo
Iro grate rakakamurwa kuita zvikamu zviviri zvine maviri akasarudzika angori anles. Chikamu chekumberi chikamu chekupedza uye kuomesa chikamu ne 32 ° Nhanho yeGrate. Iyo yekumashure chikamu ndiyo hurukuro huru uye kupisa-kunze chikamu ne 10 ° Nhanho yeGrate.
Kana mafuta aunopinda muchoto kubva kune inlet, inowira pamberi peiyo 32 ° nhanho yechiGrate. Inotungamirirwa neiyo grate inobviswa, mafuta anozotenderera kubva kumusoro kusvika pasi achienda kune choto. Nekudaro zvinobatsira pakusanganisa kwemweya unopisa uine mafuta. Zvichakadaro, mafuta anoponeswa zvakakwana nemurimi murazvo uchimhanyisa kumberi, izvo zvinobatsira pakuputika kwemanyoro. Naizvozvo, mafuta anogona kuomeswa zvakakwana mune 32 ° nhanho grate chikamu. Mafuta akaomeswa anopinda kumashure kumashure 10 ° nhanho yetemberi. Pasi pekusundira kweturu rinobviswa, mafuta anofamba achienderera mberi uye anogadzira kuunganidzwa kufambisa, kuti mafuta anogona kusanganiswa zvizere nemhepo yekutanga. Iyo yekubatanidza uye kupisa-kunze maitiro anopedzwa pasi pekuenderera mberi radiation ye kumashure arch.
4.2 kudyisa mudziyo
Madziro emberi ane midziyo maviri ekudyisa ine chikamu cheInteti ye1 * 0.5m. Pasi pechishandiso chekudyisa chine ndiro inotonhorera, iripi mhepo yekubereka. Kana uchinja kona pakati pekugadzirisa ndiro uye ndege yakatwasuka, iyo danho rekudonha pane iyo grate inogona kugadziriswa. A shaftless kaviri spiral feeder yakarongedzwa pamberi peyimwe neimwe yekudyisa mudziyo, iyo isina yepakati shaft, nekudaro ichidzivirira mhepo yemhepo inochinja mafuta pane spiral shaft.
4.3 Mhepo yepimari uye yechipiri
Matatu emhepo yechipiri akaiswa pane choto. Mhepo yechipiri pakubuda kweiyo Rear Arch inogona kusimudzira kusanganisa kwakazara kwegasi uye mweya, uye kusundira tembiricha flue gasi kuenda kumberi kufambisa, kuomesa mafuta. Mhepo yechipiri yakarongwa pamusoro peiyo yekudyisa chiteshi inogona kumutsa uye kusanganisa iyo flue gasi kubva kune chikamu chepazasi chevira, uye ipa mweya wakakwana kuti uvandudze kugona kwemusikana. Imwe neimwe yemhepo mhepo duct ine yekudzora mwanasikana, iyo inogona kugadzirisa iyo mhepo huwandu hwehuwandu zvichienderana nemamiriro ekurovera. Chikamu chepazasi chegoridhe chakakamurwa mumakamuri emhepo akati wandei, kupa mweya wekutanga kune mafuta uye kutonhora iyo grate.
4.4 kuunganidzwa kupisa pamusoro
Iyo convection tube bundle iri mu-mutsara urongwa, economizer haina pombi yemutipi mu-mutsara gadziriro, uye preheater yakatarisana neye-mutsara gadziriro. Kuti udzivise kuderera-tembiricha corroson, mhepo preheater pombi iri girazi rinobuda pombi. Shock wave soot blows yakaiswa pane yega yega convectives yekudziya yekudziya kuti udzikise iyo ashoseti.
