Title:
BURNER FOR MIXING TREATMENT OF DRY DISTILLATION GAS AND CARBIDE
Document Type and Number:
Japanese Patent JP2000329318
Kind Code:
A
Abstract:

To attain a stable combustion and a uniformed temperature distribution in a furnace by permitting a dry distillation gas to flow in and turn around the periphery of a mixing nozzle which mixes carbides and heated combustion air for jetting the mixture from the tip thereof and jetting the gas from the tip periphery of the mixing nozzle.

A generated carbide C is supplied to a mixing nozzle 2 through a carbide supply chute 6 of a mix treatment burner 1. At the same time, heated combustion air A is supplied to the mixing nozzle 2 through a heated combustion air nozzle 5 so as to jet a mixture of the carbide C and the heated combustion air A from the periphery of the mixing nozzle 2. On the other hand, dry distillation gas G is supplied to a swirling cone 3 for dry distillation gas through a gas supply pipe 7 to form a swirling flow centering the mixing nozzle 2 in the cone 3 and jetted from the tip periphery of the mixing nozzle 2. In this way, the dry distillation gas G collides and mixes with the mixture of the carbide C and the heated combustion air A at an exit 8 of the mix treatment burner. Thus, since the carbide C is subjected to premixing and then further mixed with the dry distillation gas having a good ignition quality in order to perform combustion, combustion is stabilized and uniformed temperature distribution is attained.
