Description
Technical Field
The invention relates to the technical field of micro-flame burners, in particular to a micro-flame array burner capable of burning multi-component fuel.
Background
The information disclosed in this background of the invention is only for enhancement of understanding of the general background of the invention and is not necessarily to be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
The electric heating and the flame heating are two common heating modes, and although the electric heating has the advantages of environmental friendliness, uniform temperature and the like, the energy utilization rate is low. In recent years, direct heating of flames at home and abroad is studied more, and the primary energy utilization efficiency can reach 60%. Fire for heaterThe flames can be further classified into conventional flames and micro flames. The conventional flame is generally long, which causes uneven heating of the heating object and NO generated in the combustion processxMore soot is generated. The microscale flame has the advantages of blue transparency and cleanness, and the highest heating rate of unit volume is increased along with the reduction of the scale, the absolute value of the highest temperature is reduced, the temperature gradient is reduced, and soot is not easy to generate. The micro-scale flame can overcome the defects of the conventional flame and form a clean, high-density and uniform-temperature heating field. The absolute value of the temperature of the single micro-flame is low, and a heating system meeting the high load requirement is formed by overlapping the micro-flames generated by the plurality of micro-pipes. When two micro-flames exist simultaneously, the distance between the two micro-flames needs to be taken into consideration, and the two micro-flames are prevented from being combined to form a large flame.
In actual industrial production, a large amount of combustible gas is generated, such as multi-component gas fuels such as synthesis gas (biomass/coal gasification products), coke oven gas (coking by-products), blast furnace gas (steel making by-products) and liquefied petroleum gas (petroleum distillation products), and the fuels are mostly industrial by-products, and have complex component types, unfixed content and generally low heat value. The combustion of fuels such as synthesis gas and the like is utilized to provide a heat source for the heater, and the scientific utilization of a large amount of industrial byproducts, namely low-calorific-value fuel gas can be realized.
Patent document CN 104197329B discloses a micro-flame array burner capable of generating a micro-flame array with a curved uniform temperature field. However, the inventor researches and discovers that: such existing micro-flame burners can only satisfy burners using one kind of fuel, have poor applicability to the fuel, and have limitations in practical use or production because: (1) when the fuel type is changed, the distance between the micro-pipes is not changed, the form of the formed micro-flames is changed, the micro-flames are weak in mutual influence and discontinuous in temperature field, or are combined to form a large flame, and the uniformity of the temperature field is influenced. (2) Non-uniform mixing of combustible gas with air can result in incomplete combustion and localized high temperatures, and can increase the corresponding pollutant emissions.
