Description

A high-efficiency burner with oxygen supplement function

technical field

The utility model belongs to the technical field of burners, in particular to a high-efficiency burner with the function of supplementing oxygen.

Background technique

At present, there are various types of burners used in household gas cookers on the market. According to the more common air supplement methods, they can be roughly divided into: ejector burners and blast burners. The injection burner is that the air is inhaled and mixed by the gas jet to burn in the fire hole. The blast burner uses blast equipment to send air directly into the combustion system.

The burners of general household gas stoves are mostly ejector burners. The primary air inhaled by the nozzle and the secondary air required for the gas combustion process in the fire hole are all supplemented naturally, and there is no peripheral equipment to provide air. Due to the overall structural design of the burner, appearance requirements, etc., it is difficult to replenish primary air and secondary air, which often makes the combustion conditions of the stove unsatisfactory, and abnormal combustion conditions such as incomplete combustion of gas, excessive smoke emissions, and yellow end flames occur. And the thermal efficiency is generally not high.

The ejector burner usually uses the kinetic energy of the gas to inject air, so it belongs to the ejector burner. Its working principle is that the gas flows out at a certain speed under a certain gas pressure. Under the action of the ejector tube, the gas ejects and inhales part of the primary air by its own energy. In the ejector, the gas is mixed with the primary air and passed through the burner. The fire hole in the head flows out and burns to form the Jatsen flame.

Blast-type household stove burners can be divided into: household burners that supplement primary air through fans; household burners that supplement secondary air with blast; household burners that supplement primary air and secondary air at the same time. Both the burner supplemented with primary air and the burner supplemented with blasting secondary air can achieve the purpose of improving thermal efficiency, but the performance stability of the supplemented secondary air burner is much better than that of the blasted primary air supplemented burner, which is suitable for stronger. Through reasonable design, the blower type burner supplements the secondary air. When the blower equipment stops working, the burner can also burn normally. And the burner blowing device of blowing type replenishing primary air stops working, and nozzle will not be able to inject enough primary air, and burner can not burn normally, and cooking range can't work.

The existing burner is relatively heavy due to its high height, and it is impossible to implement the sinking heat-gathering technology of the burner structurally. In order to meet the flue gas emission index, the height of the corresponding pot support is relatively high. There are cooking hanging hands that affect the customer experience. The height of the pot support increases, and the heat is easily lost with the smoke, which cannot be concentrated at the bottom of the pot, and the thermal efficiency is difficult to improve.

The plane where the oxygen supplement hole 42 of the inner ring of the inner ring fire cover 4 is located is higher than the upper plane of the outer ring of the inner ring fire cover 4, which can effectively prevent boiled liquid or other foreign matter from entering the burner; The fire outlet holes 41 and the inner circle oxygen supply holes 42 of the inner ring are arranged in a cross manner.

The inner circle of the air-mixing chamber 2 has no gas-distributing structure and is open (increasing the area of the inflow channel of the secondary air naturally introduced during combustion).

The inner ring outer ring fire hole 41 on the side of the inner ring fire cover 4 is at an angle with the oxygen replenishment hole at the top of the inner ring fire cover 4, so that the air from the oxygen replenishment hole merges with the side flame when the air flows out, increasing the flame out of the inner ring fire cover. The contact area of the fire hole on the 4 sides of the cover.

The inner ring of the inner ring fire cover 4 has a longer oxygen supplement channel. When the combustion is in progress, the cold air passes through the channel, is heated by the heat absorbed by the burner from the fire hole, and is transported to the top fire hole of the inner ring fire cover. It already has a higher temperature, which is more conducive to gas combustion.
