Oxygen-rich gas supply device, and combustion apparatus and gas stove containing same

Abstract

The invention discloses an oxygen-rich gas supply device, and a combustion apparatus and gas stove containing the same. The oxygen-rich gas supply device is used for supplying oxygen-rich gas to the combustion region of a burner and comprises an oxygen-rich gas generating portion and a gas supply portion that communicates with the oxygen-rich gas generating portion, wherein the gas supply portioncomprises a gas outlet that faces or generally faces the combustion region of the combustor. The oxygen-rich gas supply device provided by the invention provides high-concentration combustion-supporting gas for the combustion region of the combustion apparatus by using an oxygen-rich membrane technology, thereby improving combustion conditions, enhancing the combustion efficiency of a fuel and thethermal efficiency of the combustion apparatus and reducing the emission of harmful gases at the same time. The combustion apparatus can also reduce the content of nitrogen that does not participatein combustion and effectively decreases heat loss caused by the escape of nitrogen gas with flue gas. In addition, since the fuel can be sufficiently burned, the flame length of the fuel during combustion becomes shorter, a combustion reaction zone become smaller, and generated heat is more concentrated.

Description

technical field [0001] The invention relates to the technical field of combustion, in particular to an oxygen-enriched gas supply device, a combustion device including the same, and a gas stove. Background technique [0002] Combustion devices are used in many technical fields, but due to unreasonable design, there are defects such as insufficient fuel combustion, high heat loss, and low fuel utilization; at the same time, there are also problems of exhaust gas emissions caused by insufficient combustion. [0003] For example, gas cookers are one of the most commonly used cooking utensils in ordinary people's homes. Many technicians have been researching them, hoping to improve the gas combustion conditions through different technical methods, so as to better meet people's health, energy saving and environmental protection. etc. requirements. However, at present, existing gas stoves have a serious problem of insufficient combustion of fuel, resulting in a low energy utiliza...

AI Technical Summary

Problems solved by technology

However, at present, there is a serious problem of insufficient fuel combustion in existing gas stoves, resulting in low fuel energy utilization; at the same time, there are a large amount of harmful gases in the flue gas

In addition, due to insufficient oxygen supply, the combustion flame is too long and the combustion is not concentrated, which reduces the effective utilization rate of the heat of the cooker and causes serious heat loss.

In addition, the nitrogen in the air does not participate in the combustion reaction, but dissipates into the air with the flue gas, which will also cause a large amount of heat loss
