Outdoor natural gas burner

Abstract

The invention provides an outdoor natural gas burner. The burner comprises a shell, a pedestal and a fuel gas inlet, a centre drainpipe and an upper cover, wherein the lower end of shell is connected with the pedestal, and the position close to the end part of the upper end of shell is provided with a ring body; the external edge of the upper cover is provided with a downward bulge, the bulge andthe ring body form an inverted U-shaped fuel channel, and the upper part of the upper cover is provided with a concave part; and the upper end of the centre drainpipe is communicated with the bottom of the concave part, the lower end of the centre drainpipe is communicated with the pedestal, the fuel gas inlet is arranged on the pedestal and positioned between the shell and the centre drainpipe. The burner provided by the invention has the advantages of keeping flame burning under the outdoor server weather environment, and reducing the loss of the fuel gas.

Description

technical field [0001] The invention relates to an outdoor natural gas burner for landscape use. Background technique [0002] The color of the flame of the permanent flame should be orange red when the gas is not completely burned, and the shape of the flame changes with the air flow; the height of the flame is generally in the range of 300-500mm to obtain a good visual effect. Because the eternal flame is generally set outdoors, it is not only used in the landscape, but also used in some important occasions (such as commemorative sites and certain ceremonies), requiring the burner to have the performance of resisting harsh weather. [0003] To meet the color and shape requirements of the flame, the diffusion combustion method is generally used, but the current burner has no ability to withstand harsh weather such as wind and rain, especially when the flame height requirement is low. And because the gas flow rate is faster, the energy consumption per unit time is higher. ...

AI Technical Summary

Problems solved by technology

[0003] To achieve the color and shape requirements of the flame, the diffusion combustion method is generally used, but the current burner has no ability to withstand harsh weather such as wind and rain, especially when the flame height requirement is low

And because the gas flow rate is fast, the energy consumption per unit time is high

[0004] The main component of natural gas is CH 4 (methane), its combustion potential is low, the combustion speed is slow, and the flame has no obvious soot during laminar diffusion combustion, and it is easy to produce carbon deposits, which generally cannot be used in practice.
