Embodiment 1

[0031] Embodiment 1: The present invention provides a single-layer porous ceramic foam board fully premixed gas fuel burner. This embodiment provides burners with four specifications. The cross-sectional shape of the burner is square, and the gas fuel uses natural gas. The burners of four specifications can be used alone, or can be arranged and combined in multiple groups, and can be applied to heat treatment furnaces in steel or machinery industries. The burner structure is as figure 1 , 2 shown. The main body of the burner includes cooling cavity 1, foam ceramic plate 2, heat-resistant steel bracket 3, top air distribution plate 4, bottom air distribution plate 5, screws 6, spring washers 7, flat washers 8, light Al 2 o 3 Honeycomb ceramic plate 9, rectangular annular gasket 10, support column 11, cooling air inlet 12, shell bottom plate 13, mixed gas inlet 14, cooling air outlet 15, inner tapered pressure pipe 16, wherein the burner housing is composed of The cooling ch...

Embodiment 2

[0046] Embodiment 2: The present invention provides a fully premixed gas fuel burner with a single-layer porous ceramic foam plate. Its structure is basically the same as that of Embodiment 1. The difference is that the specific geometric dimensions of the burner are taken according to Group 2 in Table 1. The material of the ceramic foam plate 2 is silicon carbide, the size of the ceramic foam plate is 200mm×200mm, and the cross-sectional shape of the burner is square.

[0048]

[0049] The burners in this embodiment can be arranged and combined in multiple groups, and can be applied to heat treatment furnaces in steel or machinery industries. When several burner units are combined into a combined burner, when the burner units are replaced during use, the work of other burner units will not be affected.

Embodiment 3

[0050] Embodiment 3: The present invention provides a fully premixed gas fuel burner with a single-layer porous ceramic foam plate. Its structure is basically the same as that of Embodiment 1. The difference is that the specific geometric dimensions of the burner are taken according to Group 3 in Table 1. The size of the ceramic foam plate 2 is 300mm×300mm, and the cross-sectional shape of the burner is square. The burner can be arranged and combined in multiple groups and applied to heat treatment furnaces in the steel or machinery industry. When several burner units are combined into a combined burner, when the burner units are replaced during use, the work of other burner units will not be affected. The natural gas and air flow rates and combustion intensity of the burner are shown in Table 4.

Abstract

The invention relates to a monolayer multiporous foamed ceramic plate full-premix gas fuel burner. The monolayer multiporous foamed ceramic plate full-premix gas fuel burner comprises a burner shell composed of a cooling cavity and a shell bottom plate. A foamed ceramic plate, a honeycomb ceramic plate, a heat-resistant steel support, a top gas distribution plate, a bottom gas distribution plate and support posts are sequentially arranged from top to bottom in the cavity of the shell. Fuel and air are mixed and enter from a mixed gas inlet via a three-way pipe to sequentially pass the bottom gas distribution plate and the top gas distribution plate which are arranged at intervals, so that the mixed gas can be more uniformly distributed and burned in and on the surface of the foamed ceramic plate. The burner can be used on its own or by combining several burner units and can burn various gas fuels with heat variation range at 800-6000 kcal/m3. The burner is widely applicable to metallurgy, chemical industry, energy source, machinery and the like.

Description

technical field [0001] The invention relates to a burner, in particular to a single-layer porous foam ceramic plate fully premixed gas fuel burner. Background technique [0002] With the continuous development of my country's industry, the increasingly serious energy and environmental problems have become one of the bottlenecks restricting my country's economic development. On the one hand, my country's energy shortage and environmental pollution problems are prominent; on the other hand, my country's energy utilization level is still relatively low compared with developed countries. The prominent performances are: low energy utilization rate, low energy utilization quality, and high pollutant emissions in the combustion process. At present, the combustion of gaseous fuels in my country's industrial production is mainly atmospheric combustion characterized by free flames. This traditional premixed combustion has a very thin free flame, and its combustion inevitably has uneve...
