Return to Japanese Patent Table of Contents Synthesis Gas Producing Device Abstract PURPOSE: To uniformly mix a primary reformed gas and a burner combustion gas, to stably obtain a partially burned gas and to efficiently produce a synthesis gas in the synthesis gas producing device having a primary reforming part to steam-reform hydrocarbons and a secondary reforming part to reform the partially burned gas and utilizing the secondary reformed gas as the heat source for the primary reforming part. CONSTITUTION: A nozzle 10 for injecting a primary reformed gas and a burner injection gas nozzle 9 for injecting an oxygen-contg. gas for partial combustion are arranged vertically to the center axis of a combustion chamber, the primary reformed gas is injected against the side wall, and the burner injection gas is injected toward the nozzle 10 in the axial direction of the combustion chamber. |
