The invention belongs to the burner technology, and discloses a built-in integrated catalytic device flue gas waste heat boiler burner, which is located at the lower part of the waste heat boiler incinerator body, and a plurality of primary air branch pipes 13 are coaxial with the corresponding fuel air guns respectively. The surrounding fuel air gun is set, and an air swirler 20 is arranged at the outlet of the primary air branch pipe; the outlet of the fuel air gun and the air swirler of the primary air are located in the corresponding combustion channel; the upper end surface of the regeneration smoke distribution chamber is provided with multiple A regenerative flue gas swirler 18 and the outlet of each secondary air injection pipe 4 is set corresponding to the regenerative flue gas swirler; a plurality of combustion channels of mixed fuel gas distributed along the circumference are arranged along the inner and outer two-layer circumference Between the outlets of the mixed regenerative flue gas; the mixed regenerative flue gas and the mixed fuel gas are evenly distributed to form a mixed combustion circle with inner and outer layers. The invention has the advantages of integrated type, simple and reliable structure, convenient operation, low cost, sufficient incineration and high thermal efficiency.
Description
technical field [0001] The invention belongs to the burner technology, and is especially suitable for the high-efficiency combustion of CO-containing flue gas of a catalytic device waste heat boiler in the oil refining industry, and specifically relates to a built-in integrated catalytic device flue gas waste heat boiler burner. Background technique [0002] Refineries generally have catalytic cracking units. During the operation of the unit, catalyst regeneration aerobic combustion produces a large amount of flue gas containing about 3-10% (V) of CO and a small amount of combustible gas. This part of flue gas not only has a certain temperature of about 600 ℃, and contains a certain amount of CO gas that can be further combusted, which can release waste heat. Therefore, a flue gas waste heat boiler is generally installed at the rear end of the regeneration flue gas of the catalytic device to make full use of the waste heat of the flue gas to achieve the purpose of energy savi...
