Title:
COMBUSTOR
Document Type and Number:
Japanese Patent JP2000274618
Kind Code:
A
Abstract:

To facilitate switching between rich and lean combustions by employing the lean combustion burner section as an air supply passage when low calorie gas is used as combustion gas.

When a low calorie nozzle holder 50 is fixed, combustion gas is ejected from a nozzle 51, fed through a suction opening 31 into a rich combustion burner section 30 and ejected from the burner port thereof. Since a nozzle 52 disposed oppositely to a suction opening 41 is closed, air from a combustion fan 12 passes through the suction opening 41 and enters into a lean combustion burner section 40. Secondary air is ejected from the burner port of the lean combustion burner section 40. When such a low calorie nozzle holder 50 is employed, secondary air is ejected from the burner ports on the opposite sides of the rich combustion burner section 30 and Bunsen and semi-Bunsen type combustion takes place. In case of high calorie gas, switching can be made between rich and lean combustions by simply replacing the nozzle holder.
