Mmanụ pellet biomass bụ iji "ihe mkpofu" na ihe ubi a kụrụ n'ubi. Igwe pellet mmanụ biomass na-eji ahịhịa ahịhịa, sawdust, ọka ọka, ahịhịa osikapa, wdg. site na ịkpụzi mkpakọ. Ụzọ isi gbanwee ihe mkpofu ndị a ka ọ bụrụ akụ bụ ịchọ igwe ọkụ ọkụ biomass briquette.
Ụkpụrụ na-arụ ọrụ nke biomass pellet n'ibu mmanụ ọkụ ji esi mmiri ọkụ: mmanụ ọkụ biomass evenly gbasaa na elu grate si nri ọdụ ụgbọ mmiri ma ọ bụ n'elu akụkụ. Mgbe ịgbanyechara ya, a na-agbanye onye na-akwado ya, a na-enyocha mgbanwe mmanụ ọkụ ahụ, ọkụ na-erekwa ala. Ebe e guzobere site na grate kwụsịtụrụ ngwa ngwa na-etolite ebe okpomọkụ dị elu, nke na-emepụta ọnọdụ maka ọkụ ọkụ na-aga n'ihu ma kwụsie ike. Mgbe ọ na-ere ọkụ, ọ na-ada n'ala, na-adaba na elu-okpomọkụ nghọta grate maka oge, wee na-aga n'ihu na-ada, na n'ikpeazụ daa na ala grate. Ihe mmanụ ọkụ na-ezuru ezughi oke na-aga n'ihu na-ere ọkụ, a na-ewepụkwa ihe ntụ ntụ na-ekpochapụ na grate dị ala. Mbupu n'ime ihe mkpuchi ash nke ngwaọrụ mwepu ash. Mgbe nchikota uyi ruru n'ogo ụfọdụ, mepee ọnụ ụzọ mwụfu ntụ wee hapụ ya ọnụ. Na usoro nke mmanụ ụgbọala na-ada, nke abụọ ikuku nkesa n'ọdụ ụgbọ mmiri gbakwunyere a ụfọdụ ego nke oxygen maka nkwusioru combustion, oxygen nyere nke atọ ikuku nkesa n'ọdụ ụgbọ mmiri na-eji na-akwado combustion na ala grate, na kpamkpam ọkụ flue gas na-eduga. elu convection kpo oku site na flue gas ntinye. . Mgbe nnukwu akụkụ nke anwụrụ ọkụ na uzuzu na-agafe na nkebi ahụ, a na-atụba ha na hopper ash n'ihi inertia. A na-egbochi uzuzu dị ntakịrị ntakịrị site na ụgbụ mgbanaka na-ewepụ uzuzu ma ọtụtụ n'ime ha dabara na ntụ ntụ. Naanị ụfọdụ irighiri ihe dị oke mma na-abanye n'elu ikpo ọkụ convective, nke na-ebelata kpo oku convective nke ukwuu. Mkpokọta uzuzu n'elu na-eme ka mmetụta nyefe okpomọkụ dịkwuo mma.
Njirimara mmanụ ọkụ nke igwe biomass pellet mepụtara bụ:
① Ọ nwere ike ngwa ngwa na-etolite mpaghara okpomọkụ dị elu, ma nọgide na-enwe ọnọdụ nke combustion stratified, gasification combustion na nkwusioru combustion. Igwe ọkụ na-ekpo ọkụ na-anọ n'ime ọkụ ọkụ dị elu ruo ogologo oge. Mgbe ọtụtụ nkesa oxygen gasịrị, combustion zuru ezu na ọnụ ọgụgụ mmanụ eji eme ihe dị elu, nke nwere ike dozie ya. Nsogbu anwụrụ ojii.
② Igwe ọkụ na-adakọ nwere obere ntinye mbụ nke soot, yabụ na chaimni adịghị mkpa.
③ Mmanụ na-ere ọkụ na-aga n'ihu, ọnọdụ ọrụ na-akwụsi ike, ọ dịghịkwa emetụta ya site na mgbakwunye mmanụ ọkụ na ọkụ, na mmepụta nwere ike ikwe nkwa.
④ Ogo dị elu nke akpaaka, obere ọrụ ike, ọrụ dị mfe ma dị mma, na-enweghị usoro ọrụ mgbagwoju anya.
⑤ The mmanụ ụgbọala nwere obosara applicability na ọ dịghị slagging, nke na-edozi nsogbu nke mfe slagging nke biomass fuels.
⑥ N'ihi na ojiji nke gas siri ike na-adọ nkewa combustion technology.
Ọ nwekwara uru ndị a:
a Ọtụtụ n'ime volatiles ezigara site na elu-okpomọkụ ụlọ pyrolysis combustion ụlọ na gas-phase combustion ụlọ bụ hydrocarbons, nke kwesịrị ekwesị maka obere n'elu-oxygen ma ọ bụ n'okpuru-oxygen combustion, na ike nweta ọ dịghị nwa anwụrụ ọkụ combustion, nke nwere ike n'ụzọ dị irè kwụsị. ọgbọ nke "thermo-NO".
b N'oge usoro pyrolysis, ọ nọ na ọnọdụ ikuku oxygen, nke nwere ike igbochi nitrogen dị na mmanụ ọkụ ka ọ ghọọ nitrogen oxides na-egbu egbu. Ihe na-emetọ ihe na-esi na igwe ọkụ nke pellet mmanụ biomass bụ nke kachasị nta nke mmetọ ikuku na ihe mkpofu siri ike nke enwere ike iji ya rụọ ọrụ nke ọma.
