Study on Combustion Characteristics of H2/CO Synthetic Gas

H2/CO 합성가스의 연소 특성에 관한 연구

  • Published : 2008.06.30

Abstract

Numerical study is conducted to predict effects of radiative heat loss and fuel composition in synthetic gas diffusion flame diluted with $CO_2$. The existing reaction models in synthetic gas flames diluted with $CO_2$ are evaluated. Numerical simulations with and without gas radiation, based on an optical thin model, are also performed to concrete impacts on effects of radiative heat loss in flame characteristics. Importantly contributing reaction steps to heat release rate are compared for synthetic gas flames with and without $CO_2$ dilution. It is also addressed that the composition of synthetic gas mixtures and their radiative heat losses through the addition of $CO_2$ modify the reaction pathways of oxidation diluted with $CO_2$.ጀ䍆䭏㈰〲ㄱ㤲㈱㈷㌴㊀쀁x済Ĉ㠤⠀ጀ䩁䭏㈰〸〸㌴㤶㐷㜶㎀쀃x済ଋᴇ⠀ጀ䩁䭏㈰〲ㄱ㤲〹㠸㐴㊀쀂x済ᜌἩ⠀ጀ䩁䭏㈰〷㈴〶㜱ㄹㄵ㞀쀄x済ᘔ᠇⠀ጀ䩁䭏㈰〱ㄱ㤲ㄵ㠶㤹ㆀ쀁x済Ĉ㰨⠀ጀ䍆䭏㈰〰ㄱ㤲㈱㌵㔰㊀쀁x済ĉȡ⠀ἀऀ㘲ㄮ㌸ጀ䩁䭏ㄹ㤹ㄱ㤲〲㌹㔴㒀쀄x済ᔖⰏ⠀ጀ䩁䭏ㄹ㤶ㄱ㤲〲㌵〲㎀쀃x済᠇⤴⠀ጀ䩁䭏㈰〴ㄱ㤲㌰㐶㔴㊀쀃x済ᴓ⠞⠀ጀ䍆䭏㈰〶ㄶ㐱㤴㐲㜳㚀쀁x済ĉሧ⠀ጀ䍆䭏㈰〳ㄱ㤲㈱㌷㔱㢀쀁x済ĉᔥఀᢝ㊗⨀遹?⨀ヨ⨀‣㒗⨀恂⒗⨀炖ޗ⨀䢏抗⨀ꢝ㊗⨀債⒗⨀㢖ޗ⨀㡎䚗⨀ᶗ⨀䀹஗⨀낃Η⨀ꣅ⢗⨀җ⨀頲⮗⨀⠀ጀ䍆䭏㈰〶ㄶ㐱㤴㐲㘸㢀쀁x済ĉᔭ⠀ጀ䩁䭏㈰〸〶㤴㈴㜰㘹㊀쀈x済Ἀ⬫਀䣌傗⨀梅?⨀梱㪗⨀䢠㞗⨀䂑ʗ⨀ʗ⨀林⨀ꢗ㆗⨀쀤㦗⨀?傗⨀ꣽ㺗⨀?侗⨀僺䶗⨀逸ᮗ⨀㠸ʗ⨀ꂀ亗⨀飲䪗⨀⠀ጀ䩁䭏㈰〷㈴㜳㜵㘲㘲㞀쀈x済ἐ㬫⠀ጀ䍆䭏㈰〳ㄱ㤲㈱㌷㔹㚀쀁x済ĉᨛ⠀ጀ䩁䭏㈰〶〶ㄴ〷㈴㌸㢀쀂x済ܒ㬬⠀ጀ䩁䭏㈰〴ㄱ㤲㈹㜰㤳㒀쀂x済Ўท⠀ጀ䩁䭏㈰〴ㄱ㤲㈰㘴㤴㖀쀁x済ĉᴩ⠀ጀ䩁䭏㈰〴〳〴㌰㐷㔹㊀쀂x済ᄓب⠀ጀ䍆䭏㈰〳ㄱ㤲㈷〱ㄱ㞀쀂x済ĉ㔥⠀ጀ䍆䭏㈰〳ㄱ㤲㈱㌷㤴㒀쀁x済ĉḴ⠀ጀ䩁䭏㈰〸㌳㌳㠳㘰㈶む쀃x済ἓᨷ⠀ጀ䩁䭏㈰〱ㄱ㤲ㄱ〸ㄴ㖀쀁x済ĉ἟⠀ጀ䩁䭏㈰〲ㄱ㤲ㄸ㘶㜶ㆀ쀆x済
