Olee otú bụ combustion mmeghachi omume

Goren akpọ ọxịdashọn mmeghachi omume nke pụtara na elu ọsọ, nke na-esonyere site na okpomọkụ na nnukwu quantities na, dị ka a na-achị, a na-egbuke egbuke na-egbukepụ egbukepụ, nke anyị na-akpọ oku. The combustion usoro enyocha ahụ onwu, nke a combustion a na-anabata ndị niile na exothermic Filiks na-enwe a onwe-ngwa ngwa mmeghachi omume. Ndị dị otú ahụ onwe-osooso nwere ike ịbụ n'ihi ntọt ke okpomọkụ (t. E. Nwere a okpomọkụ engine), ma ọ bụ ìgwè nke nọ n'ọrụ ahụ (na-enwe a mgbasa uwa).

The combustion mmeghachi omume bụ a visual mma - ọnụnọ nke elu okpomọkụ mpaghara (ire), spatially nanị na ebe ọtụtụ ndị akakabarede etịbe amalite ihe (mmanụ ụgbọala) na combustion ngwaahịa. Usoro a na-esonyere na ntọhapụ nke a nnukwu ego nke thermal ike. Ka ịmalite mmeghachi omume (oku ọdịdị) chọrọ ịgbasi a ụfọdụ ego nke ike na mgbanye, mgbe ahụ, usoro aga spontaneously. Ya ọsọ na-adabere na chemical Njirimara nke bekee abuana ke mmeghachi omume, nakwa dị ka site gas ike Filiks n'oge combustion. The combustion mmeghachi omume nwere ụfọdụ e ji mara, ihe ndị kasị mkpa nke - na calorific uru nke ngwakọta bụ okpomọkụ (akpọ adiabatic), nke nwere ike theoretically ga-enweta na-ezu combustion ewepu okpomọkụ.

Site nchịkọta ala oxidizer na mmanụ ụgbọala combustion usoro nwere ike e kenyere otu n'ime atọ ụdị. The combustion mmeghachi omume nwere ike ịbụ:

- homogeneous mgbe mmanụ ụgbọala na oxidizer (tupu mbuaha) na-na gaseous ala,

- heterogeneous, nke siri ike ma ọ bụ mmiri mmiri na mmanụ ụgbọala mkpatụ na oxidant gas,

- mmeghachi omume nke combustion nke gunpowder na -agbawa agbawa.

Homogeneous combustion bụ ihe kasị mfe, nwere a mgbe nile na-agba, dabere na ihe ndị mejupụtara na molekụla okpomọkụ conduction ngwakọta, okpomọkụ ma na nsogbu.

Heterogeneous combustion bụ kasị nkịtị na ọdịdị, nakwa dị ka na vitro. Ya na-agba bụ dabere na kpọmkwem ọnọdụ nke combustion usoro na onye ahụ dị nke Efrata. Na mmiri mmiri na mmanụ ụgbọala na combustion ọsọ mmetụta dị ukwuu na ọnụego nke evaporation, na ihe siri ike - gasification ọnụego. Dị ka ihe atụ, usoro Nleta nkebi abụọ n'oge coal combustion. Ke akpa nke ha (na ikpe nke a e ngwa ngwa kpo oku) ekenyela volatiles umi (coal), na nke abụọ Burns Coke.

Combustion gas (e.g., ethane combustion) bụ dị iche iche. The gaseous ajụ nwere ike mgba a ire ọkụ na a sara anya. Ọ pụrụ ịkpali site gas na a subsonic ọsọ, na ihe onwunwe nke bụghị naanị a gaseous ajụ, ma a ngwakọta nke ezi mmiri mmiri na ihe siri ike combustible ahụ weere na oxidant. Iji hụ na mụ combustion dị otú ahụ ikpe na-achọ a pụrụ iche imewe nke oku ngwaọrụ.

Esi na ya pụta nke na-akpata na combustion mmeghachi omume na gaseous ajụ, bụ nke abụọ iche iche. First - a ịgbā na gas eruba, na-eduga a nkọ na-abawanye na usoro ọsọ. Abụrụ na now disturbances nwere ike ime ka eruba ka ọzọ ogbo - ntoputa nke ujo-efegharị efegharị na-eduga na detonation nke ngwakọta. Ìhè detonation combustion nzọụkwụ adabere ọ bụghị nanị na ya gas Njirimara kamakwa site usoro na Mgbasa kwa nha.

The combustion nke mmanụ ụgbọala na-eji na nkà na ụlọ ọrụ. Ebumnobi bụ isi ebe a bụ iji nweta kacha combustion arụmọrụ (ie. E. Iji ebuli okpomọkụ) maka a gaghị agara nkeji.

Ma na ụfọdụ eke na geological ọnọdụ nke combustion onu nwere ike ịbụ a na-akpata, na-ebu ihe ize ndụ. The ize ndụ, n'ihi na ihe atụ, bụ usoro nke n'amaghi combustion nke peat, nke na-eduga ná mpụta nke endogenous ọkụ.
