Fuel lance structure for a uniflow regenerative shaft furnace |
摘要 |
Coking of liquid fuel supplied through a fuel lance in a calcining furnace is prevented by surrounding a fuel tube in the fuel lance with a tubular jacket forming an annular gap between the jacket and the fuel tube for supplying a cooling medium through the lance. The jacket may be additionally provided with insulation which can be protected from damage caused by downwardly traveling bulk material by the additional provision of a protective tube.
