The invention discloses an oil and gas combustor capable of realizing combustion of high-purity fuel gas, flat flame and ultra-low NOx emission . The oil and gas combustor comprises a fire pan brick, an oil and gas combined gun, two to four high-purity hydrogen guns, a self-produced gas gun component, a pilot burner, a high-purity hydrogen connecting pipe, an oil and gas combined gun fuel oil connecting pipe, an oil and gas combined gun fuel oil atomization steam connecting pipe, a pilot burner connecting pipe, two self-produced gas gun connecting pipes, a combustor body, an air adjusting mechanism, four adjusting ball valves, a three-way adjusting ball valve, an ignition lamp, a fire watching lamp and a flame detection device. Fuels are classified and adjusted proportionally, so that the oil and gas combustor is suitable for low NOx combustion emission requirements under different loads; through turbulence and the Venturi effect of combustion-supporting air, NOx generation is effectively inhibited; and through special design of the fire pan brick and the nozzles of the hydrogen-rich fuel gas guns, the problem that the local temperature is too high, which is caused by local heat accumulation, is solved. The oil and gas combustor has the functions of combusting dehydrogenation tail gas, self-produced gas, such as release gas or desorption gas, and oil.
Description
technical field [0001] The invention relates to a petrochemical burner equipment, in particular to a high hydrogen gas flat flame ultra-low NOx [0002] Discharge oil-gas combined burner. Background technique [0003] At present, there are a large number of process heating furnaces. Due to the close distance between the furnace tubes and the unreasonable design of the burner flame shape, the flame will lick the furnace tube, resulting in uneven temperature on the furnace tube and local overheating areas. It is easy to cause serious coking, which greatly shortens the maintenance cycle and the service life of the furnace tube. [0004] In the 1990s, with the needs of energy saving and environmental protection, most oil refining, chemical and fertilizer plants have self-produced dehydrogenation tail gas (containing high hydrogen), analytical gas, desorbed gas, etc. The reuse of the produced gas is no longer sent to the flare for combustion. Because these refinery gases have ...
