Title (EN) PULVERIZED COAL CARRIABILITY IMPROVER
(FR) AGENT AMELIORANT LA CAPACITE DE TRANSPORT DE CHARBON PULVERISE
Abstract: front page image
(EN)A pulverized coal carriability improver which can improve the carriability of a pulverized coal and enables the pulverized coal to be used as a blown fuel for a metallurgical furnace or a combustion furnace. The improver can further provide a pulverized coal which can prevent hanging and channeling in a hopper and pipe clogging. Water-soluble inorganic salts having a polar group, such as BaCl¿2?, CaCl¿2?, Ca(NO¿2?)¿2?, Ca(NO¿3?)¿2?, Ca(Cl0)¿2?, K¿2?CO¿3?, KCl, MgCl¿2?, MgSO¿4?, NH¿4?BF¿4?, NH¿4?Cl, (NH¿4?)¿2?SO¿4?, Na¿2?CO¿3?, NaCl, NaClO¿3?, NaNO¿2?, NaNO¿3?, NaOH, Na¿2?S¿2?O¿3?, NaS¿2?O¿5?, HNO¿3?, H¿2?SO¿4?, H¿2?CO¿3?, or HC1, are affixed to a dried pulverized coal having an HGI of at least 30 in terms of the average HGI of a feed coal at an injection port of a metallurgical furnace or a combustion furnace.
(FR)Agent améliorant la capacité de transport de charbon pulvérisé pouvant améliorer le transport d'un charbon pulvérisé et permettant d'utiliser ledit charbon en tant que combustible soufflé pour un four métallurgique ou un four à combustion. Ledit agent permet également d'obtenir un charbon pulvérisé pouvant empêcher l'accrochage de la charge et l'effet de canalisation dans une trémie ainsi que le bouchage de tubes. Des sels organiques hydrosolubles présentant un groupe polaire tels que BaCl¿2?, CaCl¿2?, Ca(NO¿2?)¿2?, Ca(NO¿3?)¿2?, Ca(Cl0)¿2?, K¿2?CO¿3?, KCl, MgCl¿2?, MgSO¿4?, NH¿4?BF¿4?, NH¿4?Cl, (NH¿4?)¿2?SO¿4?, Na¿2?CO¿3?, NaCl, NaClO¿3?, NaNO¿2?, NaNO¿3?, NaOH, Na¿2?S¿2?O¿3?, NaS¿2?O¿5?, HNO¿3?, H¿2?SO¿4?, H¿2?CO¿3?, ou HCl sont appliqués à un charbon pulvérisé séché présentant un HGI d'au moins 30 en terme de HGI moyen d'un charbon de charge au niveau d'un orifice d'injection d'un four métallurgique ou d'un four à combustion.
