Document Type and Number:
Japanese Patent JPS50119007
Kind Code:
A
Abstract:
Carbonaceous solids are heated in a transfer line burner during coal gasification or a similar process by introducing a dense phase stream of the solids into the lower end of the burner in the presence of a substantially inert gas; injecting sufficient gas having a molecular oxygen content less than that of air, normally between about 1 and about 15% by volume, into the dense phase stream near the bottom of the burner to promote a transition from dense phase to dilute phase flow and initiate the combustion of carbon; and withdrawing flue gas and heated solids overhead from the burner. The use of a gas of relatively low molecular oxygen content alleviates ash fusion problems and related difficulties.
