Boiler apparatus for waste incineration

A boiler apparatus for waste incineration, comprising:

• a combustion chamber which has a waste inlet formed on one side and a combustion space formed inside the chamber in order to incinerate the introduced waste;
• plural air injection pipes, which are disposed and vertically spaced apart from one another in an upward direction from a lower part of the combustion chamber, extend around the combustion chamber, and have a plurality of injection holes formed along an extended length of the air injection pipes, in order to inject air toward a center of the combustion space;
• an air supply unit for supplying air to each of the air injection pipes, separately, in response to a control signal;
• a temperature sensor which is mounted in each of combustion spaces in respective stages vertically separated with reference to each air injection pipe within the combustion chamber, in order to measure a combustion temperature of the combustion space in each stage;
• and
• a control module for controlling operation of the air supply unit, in order to adjust an injected amount of air fed to the combustion space in each stage on the basis of a measured combustion temperature by each temperature sensor.
