Burner for gas boiler

Abstract

The present invention relates to a burner for gas boiler that produces stable combustion without lifting of flame by stably guiding gas and primary and secondary air to the inside of an upper plate and having a first slope having main fire holes to improve efficiency of ignition and combustion in a burner main body, in which a gas mixture channel is formed by a guide plate disposed at the center of the burner main bodyburner bodyor stable mixing of gas and the primary air.

Description

TECHNICAL FIELD[0001]The present invention relates to a burner for gas boilers that produce stable combustion without generating the lifting of flame by stably guiding gas and primary air to the inside of an upper plate and having a first slope having main fire holes to improve efficiency of ignition and combustion in a burner main body.BACKGROUND ART[0002]In general, burners used in gas boilers or oil boilers are devices that appropriately mix gas or oil with air and then produces combustion and classified into a red flame burner, a Bunsen burner, and a premix gas burner, according to the mixing ratio of primary and secondary air.[0003]The red flame burner is commonly used for gun-type burners in which fuel is injected and combustion is produced while air is mixed with the fuel. The Bunsen type burner, which is classified into a Bunsen burner or a semi-Bunsen burner, produces combustion, mixing fuel that is injected with primary air, and then additional secondary air is provided to...

AI Technical Summary

Benefits of technology

[0017]As described above, a burner for gas boiler according to the invention can replace existing circular burners or instantaneous bar type burners, improve the flame holding effect by forming main fire holes at an angle, and maintain the fire by constantly supplying secondary air between the main fire holes. Further, it is possible to achieve an environment-friendly boiler by reducing generation of CO, NOx, etc., because the performance of combustion is considerably improved. Furthermore, since the upper plate and lower plate of the burner main body can be made of different materials, the cost is reduced, and it is possible to reduce the width of the burner by reducing the length of the flame of the burner.

[0018]In addition, the entire size of the boiler is reduced, such that it is possible to obtain additional effects in transport, installation, etc.

Problems solved by technology

Therefore, it was difficult to produce combustion when gas pressure that is supplied decreases, such as rush hour, or the gas decreases in volume due to low temperature of the external air.

Further, because fire holes are formed at the side of the burner cover, lifting of flame was generated when the second air was supplied perpendicular to the fire holes, causing a bad combustion of the flames above the fire holes due to the lack of second air, and the upper plate of the burner was overheated due to the concentration of heat, thereby reducing the burner's life.

In addition, a plurality of separate burners is provided, thereby increasing material costs and manufacturing cost.
