Combustion device comprising orthogonally arranged channels

A combustion device comprising:

• a fuel manifold configured to distribute fuel flowing into one or more fuel inlets;
• a plurality of fuel channels configured to receive the fuel from the fuel manifold and including one or more fuel spraying holes in one end;
• an air inlet duct arranged to surround the plurality of fuel channels;
• a combustion plate configured to support one end of each of the plurality of fuel channels and including a plurality of air channels that guide air introduced into the air inlet duct in a direction perpendicular to a fuel spraying direction of the one or more fuel spraying holes;
• and
• a combustion chamber disposed toward the combustion plate,
• wherein the one or more fuel inlets comprise:
• a main fuel inlet configured to supply main fuel to a plurality of main fuel channels among the plurality of fuel channels;
• and
• a pilot fuel inlet configured to supply pilot fuel to a plurality of pilot fuel channels among the plurality of fuel channels,
• wherein the plurality of air channels comprise:
• a plurality of main air channels corresponding to fuel spraying holes of the main fuel channel;
• a plurality of pilot air channels corresponding to fuel spraying holes of the pilot fuel channel, and
• an imaginary line extending through the plurality of main air channels and an imaginary line extending through the plurality of pilot air channels intersect each other at an angle other than a right angle,
• wherein the plurality of main fuel channels are not arranged on an imaginary line extending through the plurality of pilot air channels, and
• wherein the plurality of pilot fuel channels are arranged on an imaginary line extending through the plurality of main air channels.
