Porous medium combustor with variable power

Abstract

The invention discloses a porous medium combustor with variable power. The porous medium combustor with the variable power comprises a shell (1) internally filled with non-combustible liquid (5), an inner barrel (2) penetrating through the shell in the axial direction, and a porous medium cavity (7) wrapping part of the inner barrel. The inner barrel and the shell are fixedly connected, the lower end of the porous medium cavity sinks to the position below the liquid level, and the porous medium cavity can make axial motion along the inner barrel. Fuel gas generates different intensities of pressure while flowing, and the combustor is triggered to move. A columnar combustor moves in the axial direction of the combustor, so that the effective combustion area of the combustor is changed correspondingly. When the flow is increased, the effective combustion area of the combustor is enlarged, otherwise, the effective combustion area of the combustor is reduced.

Description

technical field [0001] The invention relates to a burner, in particular to a variable power porous media burner. Background technique [0002] At present, the existing porous media burners are prone to explosion when burning flammable and explosive gases. The common porous media burners all have rated power and have a certain flow range for fuel gas. It is easy to exceed the rated range. Burn out the burner and cause an accident. For the sake of safety, it is often necessary to arrange multiple burners to adapt to the large-scale fluctuation of the fuel gas flow rate, which will inevitably lead to an increase in manufacturing costs, and the utilization rate of some burners is not high. Contents of the invention [0003] In view of this, the present invention proposes a variable power porous media burner [0004] In order to achieve the above object, the technical solution of the present invention is as follows: a variable power porous media burner, which is characterized...
