Description

One kind using the closed flames of anger burner of biological flue gas (BNG)

Technical field

The utility model belongs to the catering facility design and manufacturing technology field using biological flue gas as fuel, and particular content is related to Biological flue gas and pure oxygen mixed firinor fuel burning, the acquisition methods of pure (only moisture vapor and carbon dioxide) flue gas and technology and Quan Mi Close the structure of flames of anger pure oxygen combustor and the safe design field of program control pulse igniter.

Background technique

After the 1990s, arouse the whole world due to greenhouse effects to CO₂The attention of gas abatement, and it is domestic at present The combustion system of the outer overwhelming majority is using air as combustion adjuvant, so that the carbon dioxide gas in combustion product is directly arranged Into air, to exacerbate global greenhouse climate warming.

It is last from last century, due to CO₂Excess emissions cause greenhouse effects, each state all starts to CO₂Emission reduction is paid attention to Come.From the point of view of current research achievement, the existing burners of the overwhelming majority use air as combustion adjuvant, and this mode It will lead to the CO that burning generates₂In the atmosphere being directly discharged to without processing, the degree of atmospheric warming effect is further increased.

It is although simple and convenient with air-breathing, but it is detrimental to the collection for the carbon dioxide that burning generates, in composition of air, Nitrogen accounts for about 78%, these nitrogen participate in burning and generate nitrogenous gas, also increases the separating difficulty and cost of carbon dioxide.For This, so that Pure Oxygen Combustion Technology becomes the emphasis of Energy Section, various countries scholar research again, the advantages of pure oxygen burning, is: fuel Increased flame speeds can increase substantially the power of burner and the productivity of hot equipment；Fuel-saving consumption, due to The exhaust gas volumn of generation of burning under the conditions of pure oxygen is reduced, to reduce the heat loss taken away of smoke evacuation；The discharge of reduction pollutant, one Aspect is reduced pollutant due to the reduction of fuel consumption and generated, on the other hand since the exhaust gas volumn of unit of fuel is reduced And the raising of pollutant concentration reduces the processing cost of pollutant in flue gas；The ignition temperature for improving fuel, to increase The transformation efficiency of fuel and the grade for improving fuel.

For combustion system, using air as combustion adjuvant is fairly simple reliable method.But this mode by In being directly connected to atmosphere, combustion product CO is given₂Collection bring extreme difficulties.In the component part of atmosphere, about 78% Part is all N₂, N₂Product is generated with CO after participating in burning₂It is discharged together, which in turns increases CO₂Recovery difficult and at This.In consideration of it, Pure Oxygen Combustion Technology reappear in various countries' energy in terms of researcher eye in.Pure Oxygen Combustion Technology has following Advantage: 1, burning velocity is fast, can greatly improve the production efficiency of the burner rating and heat power equipment under the conditions of unit；2, Fuel is saved, since fuel burns under the conditions of pure oxygen, the exhaust gas volumn of generation is greatly reduced, therefore heat loss caused by smoke evacuation It greatly reduces；3, pollutant emission is low, this is because the reduction bring fluff pulp of one side fuel usage amount reduces, It on the other hand is then the pollutant concentration to be treated during the exhaust gas volumn generated due to the fuel of same units is reduced and discharged fume The cost for improving the simplification of bring treatment process, efficiently further reduced fume treatment；4, oxygen-enriched combustion technology can be significantly Improve ignition temperature, the abundant after-flame of fuel, to improve the transformation efficiency and grade of fuel.

Current pure oxygen combustor is gradually applied in industrial circle, but traditional Civil energy-saving cooking stove fuel consumption is big, Discharge capacity of carbon dioxide is also very important, needs to be transformed existing gas stove, will utilize the pure oxygen burning in special dimension Applied in Civil energy-saving cooking stove, it is of great significance to the internationalization exhaust requirements of negative carbon row.

Currently, pure oxygen burning device comes into industrial application field, but the Civil energy-saving cooking stove ownership of traditional approach is big, tires out The fuel consumption of meter is also very big, causes CO₂Discharge amount is very huge.Therefore, it is fired using the pure oxygen used in special dimension It burns principle to be transformed currently used domestic gas cooking stove, there is highly important meaning to the International Emissions index of negative carbon row Justice.

Summary of the invention

The target of the utility model is to provide a kind of closed flames of anger that can be used for the dual-purpose negative carbon row's combustion system of the work people Combustion adjuvant is changed to pure oxygen by burner, can substantially reduce heat loss, the theoretical temperature combustion of raising fuel, increasing that flue gas is taken away The quantity of heat production of heating equipment, additionally can be by the separation and recycling of the flue gas to pure carbon dioxide and water, to drop The trapping energy consumption of low carbon dioxide.

The purpose of this utility model is realized by following technical scheme:
