An Alcohol-based Fuel Swirl Atomization Burner Can Realize Secondary Oxygen Combustion

Abstract

The invention relates to an alcohol-based fuel cyclone atomizing combustor capable of achieving secondary oxygen supply combustion. The alcohol-based fuel cyclone atomizing combustor comprises an electromagnetic pump, a combustor set and an air blower; the combustor set comprises an outer container, an inner container, a double-arc-shaped fireproof ring and a thermal reaction cover, the inner container is located in the outer container, the double-arc-shaped fireproof ring is arranged on the upper portion of the outer container, the thermal reaction cover is installed at the top of the double-arc-shaped fireproof ring, an upper end opening and a lower end opening of the double-arc-shaped fireproof ring are each shaped like a horn mouth bending outwards, primary combustion oxygen supply holes are formed in the side wall of the inner container, and secondary combustion oxygen supply holes are formed in the upper end face of the inner container. The alcohol-based fuel cyclone atomizing combustor has the advantages that oxygen is supplied to alcohol-based fuel secondarily for combustion, and the alcohol-based fuel is combusted more completely; more fuel input quantity can be increased to obtain high combustion efficiency and a clean emission effect; the low-power small-size high-frequency direct-current air blower is adopted to replace a large-power intermediate-frequency alternating-current fan, installation space and electricity are saved, and meanwhile noise is reduced.

Description

technical field [0001] The invention relates to the field of combustion heating, in particular to an alcohol-based fuel swirl atomization burner capable of realizing secondary oxygen supply combustion. Background technique [0002] Ordinary alcohol-based fuel burners, alcohol-based fuel burners, etc., the working principle of the burner is to directly inject alcohol-based fuel, atomize or gasify it and mix it with air for combustion, and the best combustion effect of methanol is not obtained. The combustion temperature is difficult to reach 1000 ℃. The content of harmful substances carbon monoxide, nitrogen oxides, methanol, and formaldehyde in the exhaust gas exceeds the amount specified in the emission standard. At present, the domestic blowers matched with the above-mentioned common alcohol-based fuel burners and alcohol-based fuel burners are all AC medium-pressure centrifugal fans, which are relatively large in size and noise. For example, AC centrifugal fans with a r...

Problems solved by technology

However, there is a problem that under the condition that the size of the inner liner of the burner remains unchanged, it is impossible to increase the input of more fuel, and at the same time obtain the effect of high combustion efficiency and clean emissions
