Nepo iyo PFI neISO miyero ichiita seyakafanana munzira dzakawanda, zvakakosha kuti ticherechedze mutsauko unowanzo kuve wakajeka mune zvakatemwa uye nzira dzakatariswa dzekuyedza, sezvo PFI neISO zvisingawanzo kuenzaniswa.

Nguva pfupi yadarika, ndakakumbirwa kuti ndienzanise nzira uye zvirevo zvinorehwa muPFI zviyero neinotaridzika yakafanana ISO 17225-2 standard.

Ramba uchifunga kuti mazinga ePFI akagadziridzwa kuNorth America huni pellet indasitiri, nepo kazhinji, iyo ichangobva kuburitswa ISO zviyero zvakada kufanana neyaimbova EN zviyero, izvo zvakanyorerwa misika yeEurope. ENplus neCANplus ikozvino vanonongedza zvakatemwa zvemhando yemakirasi A1, A2 uye B, sekutsanangurwa kwazvino muISO 17225-2, asi vanogadzira vanonyanya kugadzira "A1 giredhi."

Zvakare, nepo PFI zviyero zvichipa maitiro ekutanga, akajairwa uye ekushandisa mamakisi, ruzhinji rwevagadziri vanogadzira giredhi rekutanga. Ichi chiitiko chinoenzanisa zvinodiwa zvePFI's premium giredhi neISO 17225-2 A1 giredhi.

PFI yakatarwa inobvumira kuwanda kwehuwandu hwemakumi mana kusvika makumi mana nemapaundi pacubic tsoka, nepo ISO 17225-2 inoreva huwandu hwe600 kusvika 750 makirogiramu (kg) pa cubic mita. (37.5 kusvika 46.8 pounds per cubic foot). Nzira dzekuyedza dzakasiyana mukuti vanoshandisa midziyo yakasiyana-siyana, nzira dzakasiyana dzekutsikirira uye kureba kwekudira kwakasiyana. Pamusoro pemisiyano iyi, nzira dzese dziri mbiri dzine huwandu hukuru hwekusiyana nekuda kwekuyedzwa kunoenderana nehunyanzvi hwemunhu. Pasinei nekusiyana kwese uku uye kusiyana kwakasiyana, nzira mbiri idzi dzinoita sedzinoburitsa mhedzisiro yakafanana.

PFI dhayamita renji i 0.230 kusvika 0.285 inches (5.84 kusvika 7.24 millimeters (mm). Izvi zvinoenderana nekuti vagadziri vekuUS vanonyanya kushandisa mafirita ane hafu yeinch uye mamwe akati kurei zvishoma. ISO 17225-2 inoda kuti vagadziri vataure 6 kana 8 mm, imwe neimwe iine kushivirira kuwedzera kana kubvisa 1 mm, zvichibvumira huwandu hunogona kubva pa5 kusvika 9 mm (0.197 kusvika 0.354 inches) Tichifunga kuti dhayamita 6 mm inonyanya kufanana neyakajairwa chikamu chimwe muzvina-inch (6.35 mm). ) saizi yekufa, zvinotarisirwa kuti vagadziri vataure 6 mm Hazvina chokwadi kuti chigadzirwa che dhayamita 8 chingakanganisa sei kushanda kwechitofu.

Nekusimba, nzira yePFI inotevera nzira yetumbler, apo makamuri ekamuri ari 12 inches ne 12 inches ne 5.5 inches (305 mm ne 305 mm ne 140 mm). Iyo ISO nzira inoshandisa tumbler yakafanana idiki zvishoma (300 mm ne300 mm ne120 mm). Ini handina kuwana mutsauko muhukuru hwebhokisi kuti ukonzere mutsauko wakakura mumhedzisiro yebvunzo, asi mudzidziso, iro bhokisi rakakura zvishoma rinogona kuratidza bvunzo ine hukasha yePFI nzira.

PFI inotsanangura faindi sechinhu chinopfuura nepaimwe-eighth-inch waya mesh skrini (3.175-mm square hole). Kune ISO 17225-2, faindi dzinotsanangurwa sezvinhu zvinopfuura nepakati peiyo 3.15-mm yakatenderera gomba skrini. Kunyangwe iyo skrini saizi 3.175 uye 3.15 inoita seyakafanana, nekuti iyo PFI skrini ine masikweya maburi uye ISO skrini ine maburi akatenderera, mutsauko weaperture size ingangoita makumi matatu muzana. Saka nekudaro, bvunzo yePFI inoisa chikamu chakakura chechinhu sefaindi zvichiita kuti zvinyanye kupasa bvunzo dzefaindi dzePFI, kunyangwe paine chinodikanwa chefaindi yeISO (zvese zvinonongedza muganho wefaindi we0.5 muzana yezvinhu zvakabhegi). Uye zvakare, izvi zvinoita kuti iyo durability bvunzo mhedzisiro iite ingangoita 0.7 yakaderera kana yakaedzwa kuburikidza nePFI nzira.

Nezvemukati wemadota, zvese PFI neISO zvinoshandisa tembiricha dzakangofanana pakupisa, 580 kusvika 600 madhigirii Celsius ePFI, uye 550 C yeISO. Ini handisati ndaona mutsauko wakakura pakati petembiricha idzi, uye ndinofunga nzira mbiri idzi dzekupa mhedzisiro yakafanana. Muganho wePFI wemadota i1 percent, uye ISO 17225-2 muganhu wemadota i0.7 percent.

Nezvekureba, PFI haibvumiri kupfuura 1 muzana kuti ive yakareba kupfuura 1.5 inches (38.1 mm), nepo ISO isingabvumiri kupfuura 1 muzana kuti ive yakareba kupfuura 40 mm (1.57 inches) uye pasina pellets yakareba kupfuura 45 mm. Kana tichienzanisa 38.1 mm 40 mm, iyo PFI bvunzo yakanyanya kuomarara, zvisinei, iyo ISO yakatarwa kuti hapana pellet inogona kureba kupfuura 45 mm inogona kuita kuti ISO zvirevo zviome. Panzira yekuyedza, bvunzo dzePFI dzakanyanya, mukuti bvunzo inoitwa pashoma saizi ye2.5 mapaundi (1,134 gramu) nepo ISO bvunzo inoitwa pamagiramu makumi matatu kusvika makumi mana.

PFI neISO inoshandisa nzira dze calorimeter kuona kukosha kwekudziya, uye ese ari maviri maedzo anotaridzirwa anopa mhedzisiro yakaenzana kubva kuchiridzwa. Kune ISO 17225-2, zvisinei, muganho wakatarwa wehuwandu hwesimba unoratidzwa seyambuto calorific kukosha, inonziwo yakaderera kudziyisa kukosha. Kune PFI, kukosha kwekudziya kunoratidzwa seyakanyanya calorific kukosha, kana yakakwirira yekudziya kukosha (HHV). Aya ma parameter haana kuenzaniswa zvakananga. ISO inopa muganho wekuti maA1 pellets anoda kuve akakura kupfuura kana kuenzana ne4.6 kilowatt-awa pakg (yakaenzana ne7119 Btu paundi). Iyo PFI Standard inoda kuti mugadziri abudise hushoma HHV sekutambirwa.

Iyo ISO nzira yechlorine mareferensi ion chromatography senzira yekutanga, asi ine mutauro wekubvumidza akati wandei akananga maitiro ekuongorora. PFI inonyora nzira dzakawanda dzinogamuchirwa. Zvese zvinosiyana mukuona kwavo miganhu uye chiridzwa chinodiwa. PFI inogumira pakushandisa chlorine i300 milligrams (mg), pakirogiramu (kg) uye chinodiwa neISO 200 mg pakg.

PFI parizvino haina simbi dzakanyorwa muchiyero chayo, uye hapana nzira yekuyedza inotsanangurwa. ISO ine miganhu yesimbi sere, uye inonongedzera ISO yekuyedza nzira yekuongorora simbi. ISO 17225-2 inonyorawo zvinodiwa kune akati wandei ma paramita asina kubatanidzwa muPFI zviyero, kusanganisira deformation tembiricha, nitrogen uye sarufa.

Nepo iyo PFI neISO miyero ichiita seyakafanana munzira dzakawanda, zvakakosha kuti ticherechedze mutsauko unowanzo kuve wakajeka mune zvakatemwa uye nzira dzakatariswa dzekuyedza, sezvo PFI neISO zvisingawanzo kuenzaniswa.
