Method for ignition and combustion-supporting treatment of flame-retardant petrochemical residual oil by using Brown gas

Abstract

The invention discloses a method for ignition and combustion-supporting treatment of flame-retardant petrochemical residual oil by using Brown gas. The method of igniting and supporting combustion ofresidual oil comprises following steps that S1, residual oil is stored in a preheating device, and the preheating device preheats the residual oil; S2, the preheated residual oil is conveyed into a residual oil atomization device by a residual oil conveying pump, and the residual oil atomization device is positioned in a high-temperature mixing ignition chamber; S3, an air blower and the residualoil atomization device are matched to atomize the residual oil, and the atomized residual oil is sprayed into the high-temperature mixing ignition chamber and a combustion chamber; S4, ignition devices in the high-temperature mixing ignition chamber and Brown gas ignition nozzles work cooperatively to ignite the atomized residual oil; and S5, the ignition devices arranged inside the combustion chamber and the Brown gas ignition nozzles are used for supporting combustion of the atomized residual oil which is not sufficiently combusted. In the method, the ignited and atomized residual oil and enough air are further fully combusted when passing through the high-temperature combustion-supporting area, so that the combustion degree and efficiency of the residual oil are improved.

Description

technical field [0001] The invention relates to the technical field of petroleum refining residual oil treatment, in particular to a method for treating flame-resistant petrochemical residual oil by using Brown gas to ignite and support combustion. Background technique [0002] After the light, medium and heavy components of petroleum are extracted during the refining process, there will be some residual residual oil. These residual residual oils contain asphalt colloid and other components, have high viscosity, high ignition point, and are not easy to burn. But its combustion value can reach more than 6300-6900Kcal / Kg, which is a heavy fossil fuel with high calorific value. The existing method to deal with this type of fuel is to add industrial furnace fuels for mixed combustion, but adding industrial furnace fuels will slow down the burning speed of residual oil and reduce the combustion efficiency. [0003] The present invention proposes a method of using Brown gas as an...
