Description

A New Atmospheric Cooker

technical field

The invention relates to a novel atmospheric combustion embedded household gas cooker.

Background technique

Atmospheric combustion built-in household gas stoves are popular with consumers for their large and concentrated firepower, but how to improve the thermal efficiency of products has always been the focus of the industry and consumers.

According to the airflow direction of the fire hole on the outer ring of the gas stove, the gas stove can be roughly divided into three types: inner fireworks, outer fireworks and two-way fire. According to the existing data, the thermal efficiency of the inner firework gas cooker is relatively high. The main reason is that when the flame of the outer ring fire cover is sprayed inward, it can heat the bottom of the cooker, which is equivalent to increasing the heating area.

From the analysis of the structure of the gas stove, there is still room for improvement in the thermal efficiency of the existing internal fireworks gas stove. At present, most of the inner fireworks gas stoves in China still use the traditional outer fireworks structure burner, and in the traditional outer fireworks structure, the secondary air supplement between the inner and outer ring burners is only for the gas ejected from the center burner. The relative amount is small, but after adopting the inner fireworks combustion method, the amount of secondary air required for gas combustion increases greatly, so it will appear that the gas ejected from the outer ring fire cover cannot be completed in the space inside the outer ring fire cover. For complete combustion, the gas flame needs to extend to the space beyond the outer ring fire cover, in order to contact more secondary air and complete complete combustion.

The characteristic of atmospheric combustion is that the gas completes the combustion process in two stages: after the gas is ejected from the nozzle, the surrounding air enters the ejector tube, mixes evenly, and is ejected from the fire hole of the fire cover; when the air-gas mixture is discharged from the fire After the hole is ejected and ignited, the gas in the mixture reacts with the air to form an intermediate substance, and at the same time emits part of the heat; after the intermediate substance contacts with the surrounding secondary air, a chemical reaction occurs to complete complete combustion and generate carbon dioxide and water while releasing a lot of heat.

It can be seen from this that the internal pyrotechnic burner with the outer flame structure burner, because the secondary air supply between the inner and outer ring fire covers is less, in fact the secondary combustion of gas is still between the outer ring fire covers In addition, most of the chemical reaction heat is distributed in the area outside the outer ring fire cover, which is not much different from ordinary outer fireworks cookers. The design idea that the inner fireworks heat is gathered in the center of the burner has not been fully realized, so it is difficult to achieve a large thermal efficiency. Increased range.
