摘要： A combustion apparatus includes a combustion chamber and a single-type regenerative combustion burner. The burner is arranged with respect to the combustion chamber so that a direction in which burnt gas returns to the burner is not opposed to a direction in which fuel and supply air are expelled from the burner. This combustion apparatus is applicable to various types of industrial furnaces including various types of boilers, for example, a crucible-type furnace.

摘要： In combustion using air preheated by regenerative direct heat exchange between exhaust gas and the combustion air using a regenerator as a heat exchange medium, the present invention relates to a low-NOx burner that is effective for reduction in NOx in a mid-temperature range which has been conventionally difficult to be realized and improves stability of the flame. According to this low-NOx burner, at an outlet of an air throat 24 for flowing a full quantity of the combustion air is disposed a burner tile 22 having an enlarged diameter portion 23 thereof whose diameter is larger than that of the outlet, and a fuel nozzle 19 for injecting the fuel from the enlarged diameter portion 23 of the burner tile is also provided. Further, a flow of the combustion air injected from the air throat 24 produces a negative pressure at a secondary combustion chamber 25 surrounded by the enlarged diameter portion 23 of the burner tile around the air throat 24 to cause a strong furnace exhaust gas recycle to occur, and a flame holding area X1, a furnace exhaust gas recycle combustion area X2 and a slow combustion area X3 are formed.

摘要： A small once-through boiler can avoid burning caused due to excessive heating of water pipes and burning around a fire hole of a burner in particular and heighten the heat load of a combustion chamber to further reduce the size of the system as compared with a prior art boiler. In the small once-through boiler, at least one regenerative burner system 20 is provided in a combustion chamber 1, the regenerative burner system 20 carrying out supply of combustion air A and exhaust of combustion gas E through a regenerator 22 and relatively changing flows of the combustion gas E and the combustion air A with respect to the regenerator 22 so as to supply the combustion air A via the regenerator 22 heated by heat of the combustion gas. Water pipe group 4 is provided apart from the combustion chamber wall surface 3 to form a passage 12 between the rear surface of the water pipe group 4 and the combustion chamber wall surface 3. Communicating openings 10 and 11 through which the combustion gas C passes are formed between adjacent water pipes at upper and lower ends of the water pipe group 4 so that a part of the combustion gas C can pass through the passage 12 provided at the rear of the water pipe group 4, whereby a part of the combustion gas C flows from the lower communicating openings 11 into the passage 12 to move upward and again flows from the upper communicating openings 10 into the combustion chamber 1.
