Abstract

The invention provides a novel integrated device for igniting by atomizing fuel oil through steam. According to the novel integrated device for igniting by atomizing the fuel oil through the steam, the fuel oil is atomized through the steam, the atomization impact energy is high, then the atomization effect can be fully guaranteed, and the ignition success rate can be increased; the problems aboutthe unstable effect of mechanical atomization, the lowered atomization effect caused by low pressure of compressed air, the high cost of high pressure air, the insufficient in-plant gas source and the like are solved; due to the fact that atomized liquid drops of the fuel oil are relatively small, the combustion speed is high, the fullness of flames in a boiler is high, and radiation blind spotscan be effectively reduced; supplied oil is combusted thoroughly and completely, and the fuel oil is effectively saved; and the device is simple in structure, easy to manufacture, not high in materialand machining requirements, low in original investment and easy to implement and apply.

Description

Technical field [0001] The invention relates to the technical field of circulating fluidized bed boilers, in particular to a novel steam atomized fuel oil ignition integrated device. Background technique [0002] The oil gun is the core of the ignition system of the circulating fluidized bed boiler. The stable atomization performance of the oil gun is the key to ensure good fuel atomization and successful ignition. A good atomization effect can not only atomize the fuel into small droplets to facilitate ignition and burnout, but also reduce the amount of fuel and reduce the cost of ignition fuel. [0003] At present, the existing oil guns used in the ignition system of fluidized bed boilers mainly include the following types: single oil guns such as mechanical atomizing spray guns and air atomizing spray guns. [0004] The mechanical atomization structure is simple, but the atomization effect is general. In addition, when the oil pressure is low, there are disadvantages of poor atom...
