Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0015] Such as figure 1 As shown, the burner in this embodiment includes a combustion chamber surrounded by the outer wall of the combustion chamber, and a refractory material 9 is poured on the inner wall of the combustion chamber. The end of the combustion chamber is provided with a smoke exhaust hole 10, and the outside of the smoke exhaust hole 10 is an expansion chamber 17. A conical nozzle is provided at the front end of the combustion chamber, and a gas injection inlet, a primary air injection inlet, and a high-pressure igniter are arranged on the conical nozzle, and a tapered conical flame stabilizer 11 is arranged behind the nozzle. Stream jets are good for flame stabilization. The axis of the combustion chamber coincides with the axis of the conical nozzle. The fuel gas pipe and the primary air distribution pipe coaxially arranged outside the com...

Abstract

The invention relates to an efficient and energy-saving environment-friendly high-pressure burner, wherein smoke which has high temperature and high pressure as well as low pollution and is generated by the burner can be used in industries of petroleum, chemical engineering and the like. The burner comprises a combustion chamber, the front end of the combustion chamber is provided with a tapered spray nozzle which is provided with a fuel gas spray inlet and a primary air spray inlet, and a fuel air tube and a primary air distribution tube are respectively communicated with the fuel gas spray inlet and the primary air spray inlet. A combustion chamber protective casing is arranged outside the outer wall of the combustion chamber, an annular channel is formed by the surrounding of the outerwall of the combustion chamber and the combustion chamber protective casing, a secondary air inlet is communicated with the annular channel, the tail end of the outer wall of the combustion chamber is provided with a secondary air auxiliary inlet, and secondary air enters the combustion chamber through the secondary air auxiliary inlet. The burner realizes secondary air distribution to the combustion chamber by the secondary air, and secondary air distribution not only plays the role of cooling and heat preservation to the combustion chamber, but also can conduct secondary air distribution combustion supporting by being preheated to certain temperature, thus improving combustion efficiency and saving energy.

Description

technical field [0001] The present invention relates to a high-efficiency, energy-saving and environment-friendly high-pressure burner in petroleum, chemical and industrial furnaces. In submerged combustion, the high-temperature and high-pressure flue gas can be used to evaporate and concentrate acid, alkali and salt solutions, efficiently heat the solutions, and perform sewage treatment. Background technique [0002] In thermal equipment such as petroleum, chemical, and industrial furnaces and dryers, fuel combustion and transfer processes commonly referred to as "three transfers"—heat transfer, mass transfer, and momentum transfer—take place. Theories guiding the study of these processes are fuels and their combustion, gas mechanics, heat and mass transfer. In thermal equipment with combustion process, it should be said that combustion is the most basic process and its "source", while various transfer processes are nothing but "flow". In today's society where the environ...
