Abstract

PURPOSE:To contrive higher stable-combustion performance, by equipping a fuel-air mixture ejecting port with a porous member in such a condition that a fuel-air mixture is passed through a multiplicity of holes, and that the porous member functions also as a flooring material for a base part of combustion flames. CONSTITUTION:Fuel-air mixture ejecting ports 14... are separated from each other by a partition plate 15 perforated at a plurality of positions along the circumferential direction, and a porous member 16 composed of a sheet of annular metal net is disposed in close contact with a surface of the plate 15 on the side of a mixing chamber 15, transverse the ejecting ports so that a fuel-air mixture can pass through a multiplicity of holes in the member 16. A fuel-air mixture consisting of a fuel gas and combustion primary air is ejected into a combustion cylinder 11 in a well-mixed state. Further, secondary air is ejected from apertures 12... orthogonally to the ejecting direction of the fuel-air mixture, so that the mixture is favorably mixed with the secondary air. In addition, the porous member 16 functions also as a flooring material for a base part of combustion flames, whereby fluctuation of the combustion flames is prevented, and stable-combustion performance is enhanced markedly.

Description

[Detailed description of the invention]

[0001]

[Industrial application field]

The present invention has a completely new configuration. [0002]

[Conventional technology]

For example, a burner that is attached to a household gas hot water heater, and is placed across the spout and is used to blow out meter gas and combust the spouted mixed gas. Concerning Kuna. ) In order to make gas heating equipment more compact, it is necessary to

【Effect of the invention】

As a result of the above actions, high-load combustion is possible while reducing the supply pressure of the combustion air supply device, and it is possible to
In particular, we have now been able to provide Gunbana for home use. [0008]

【Example】

Hereinafter, first, an embodiment of the burner according to the present invention will be described [0009] A first air port to which approximately 20 mm of burning air A is forcibly supplied by a blower (not shown) etc. A plurality of first air ports are drilled in one direction to equalize the air volume. In order to form holes 3 and 4, a fuel gas supply pipe 6fa (such as a blower) with a closed end to which approximately 100 mm is fed is made into a small size, passing through the center of the outer cloth 2 whose tip is slightly constricted. The explanation will be based on one drawing, which is advantageous for making the device more compact, making less noise, less likely to cause backfire, and making the device more compact. A second near-pore η body 5 is connected to the upper part of the case 2 which forms fuel 1 at a relatively low supply pressure of q H20, and is connected to the second near port η body 5 through the periphery 3. City gas G for fuel is arranged, and the mixed gas outlet opening of the fuel gas supply pipe 6 is a partition plate porous member.
