Abstract
An object of the present invention is to provide a combustion apparatus in which a space which does not contribute effectively to the combustion of fuel is less prone to be produced in a furnace because burners are not disposed at the corners of the furnace. The furnace having a square horizontal cross section is provided with the burners so that an in-furnace injection direction axis line of the burner is tangent to an imaginary circle. The burner is disposed at one place on a front wall, rear wall, right side wall, and left side wall of the furnace each, at a total of four places. The burner on each wall is installed so that the intersection of the in-furnace injection direction axis line of the burner and the furnace wall surface is apart from a furnace corner (corner point) by a length L1. The value of the length L1 is 15% of a length L of one side of width of the inside wall of the furnace when the furnace is viewed from the top.
