Temperature field adjustable type high efficiency burnt gas pulsating combusting device

Abstract

The invention relates to a highly efficient fuel gas pulsating combustor with an adjustable temperature field, which is composed of fuel gas inlet pipes, air inlet pipes, a combustion chamber, a heat releasing chamber and a furnace pipe, wherein, at least a group of fuel gas inlet pipes and air inlet pipes are arranged and connected at intervals at a tubular end of the combustion chamber, the other end of the combustion chamber is connected with the heat releasing chamber, and a plurality of branch furnace pipes are radially connected on an arc shaped end socket of the outlet of the heat releasing chamber. The diameter of the cylinder of the heat releasing chamber connected with the combustion chamber is larger than that of the combustion chamber, at least one flow flexing plate is radially arranged inside the heat releasing chamber, and isomorphic or heterogeneous pore passages are arranged on each flow flexing plate. The highly efficient fuel gas pulsating combustor with the adjustable temperature field of the invention has the advantages of high combustion efficiency, combustion intensity and heat exchange performance, low pollutant content in the discharged flue gas, long service life and improved working efficiency.

Description

technical field [0001] The invention belongs to burners, in particular to a high-efficiency gas pulse burner with adjustable temperature field. Background technique [0002] Crude oil plus (heat) water transportation in my country's oilfields is an indispensable process link in crude oil production. At present, the main technical means to ensure the realization of this link is to use natural gas as fuel and adopt conventional heating (furnace) equipment in a steady state combustion mode, such as water jacket heating furnaces, in order to improve the thermal efficiency of these heating equipment. The key component of these devices is the burner. Existing pulsating burners were tested for temperature field distribution. It was found that the temperature field of the pulsating burner was extremely sharp and the surface temperature distribution was extremely uneven, especially when the tailpipe was connected to the combustion chamber. The temperature at the furnace is extremely...

Problems solved by technology

The key component of these devices is the burner. Existing pulsating burners were tested for temperature field distribution. It was found that the temperature field of the pulsating burner was extremely sharp and the surface temperature distribution was extremely uneven, especially when the tailpipe was connected to the combustion chamber. The temperature is extremely high, and the difference from the average temperature of the combustion chamber is more than 300 degrees. In addition, the scaling of the oily medium causes the heat to not be transmitted in time, which eventually leads to the failure of the tailpipe of the pulsation burner, and then the pulsation combustion heating furnace cannot work normally, affecting the normal operation of production.
