Combustion type harmful substance removing apparatus

A combustion detoxifying apparatus comprising:

• a combustion chamber;
• and
• a burner for injecting a raw gas containing toxic components, an inert gas, a combustion assisting gas and a fuel gas into the combustion chamber;
• the burner being a multi-wall pipe burner having a raw gas nozzle for injecting the raw gas, a lift gas nozzle for injecting the inert gas formed to surround the raw gas nozzle, a raw gas combustion assisting gas nozzle for injecting a gas for assisting combustion of combustible components in the raw gas formed to surround the lift gas nozzle, a fuel gas combustion assisting gas nozzle for injecting a gas for assisting combustion of the fuel gas formed to surround the raw gas combustion assisting gas nozzle, and a fuel gas nozzle for injecting the fuel gas,
• wherein the multi-wall pipe burner is attached to the combustion chamber via a pre-combustion chamber having a capacity which is smaller than that of the combustion chamber.
