Description
Technical Field
The invention relates to the technical field of combustion equipment, in particular to a combustion part and a combustor.
Background
The burner is a general term for a device for ejecting fuel and air in a certain manner to perform mixed combustion. The burners are classified into industrial burners, civil burners and special burners according to types and application fields. Commonly used household burners include gas boilers, gas ranges, high fire gas ranges, infrared gas ranges, and combustion heads of gas water heaters.
The power of the gas boiler is more than 200kW, and the gas is sprayed out from the small hole, mixed with air blown into the large cylinder by the fan, and ignited to form integral cylindrical conical flame. The traditional burner head is formed by mixing fuel gas with air in a combustion disc and igniting the fuel gas, belongs to diffusion flame combustion, and has the advantages of simple structure, mature technology, low cost and high emission concentration of CO and NOx. The main body of the full-premixing metal fiber surface combustion head is a temperature-resistant metal fiber net, a full-premixing fan and a valve group are required to be matched for use, the flame length is shortened, the local high temperature is avoided, the combustion time is reduced, so that the nitrogen reduction is realized, although the emission concentration of CO and NOx is low, the cost is high, and the risk of blockage and tempering of a combustor exists; the staged combustion head (dense-dilute combustion head) introduces air or fuel into a furnace in multiple stages to complete combustion, reduces generated NOx into N2 by manufacturing reducing atmosphere to realize nitrogen reduction, and has the advantages of relatively complex structure, mature technology, higher cost, limited nitrogen reduction effect (difficult to achieve ultra-low emission) and high CO emission concentration.
The power of the gas stove is 3-5kW, the pipeline gas is ejected from the small holes arranged on the inner disc and the outer ring after ejecting air, and the flame is divided into two layers after ignition: the fuel gas and the injected air form rich-combustion premixed combustion flame inside; the residual fuel forms a diffusion combustion flame with ambient air on the outside. The traditional cooking range is characterized in that gas is used for injecting primary air into a cooking range structure and mixing the primary air, premixed gas is ignited and then contacts with secondary air through diffusion to complete a combustion process, and the traditional cooking range is simple in structure, mature in technology and low in cost, but is low in heat efficiency and high in emission concentration of CO and NOx; the combustion plate of the infrared stove is a porous ceramic plate, gas injects air to enter the stove head for mixing, the ceramic plate is heated by flame combustion to convert into infrared combustion, but the ceramic is easy to damage, the combustion-supporting gas is insufficient, the combustion is easy to be insufficient, the cost is high, the heat efficiency is high, and the emission concentration of NOx and CO is high; the burner structure of the high fire stove has no special part, requires high gas pressure, generally injects combustion-supporting air and provides combustion-supporting air by a fan, and the like, has simple structure, mature technology and low cost, but has low thermal efficiency and high emission concentration of CO and NOx.
The power of the strong fire stove is 5-30 kW; after the gas in the pipeline and the air blown out by the fan are mixed in the pipeline, the gas is sprayed out from the holes arranged on the inner disc and the outer ring, and after ignition, oxygen-enriched flame is formed, so that the firepower is strong, the temperature is high, but the combustion is uneven, and the emission of CO and NOx is high.
The power of the infrared stove is 3-5 kW; after the gas in the pipeline is used for ejecting air and ignited from the honeycomb disc, the flame retracts into a honeycomb pore channel to carry out short flame combustion, the heated honeycomb body forms a high-temperature heat accumulator to emit infrared rays for heating, and the infrared burner is basically the same as the infrared stove in structure and characteristics, mainly burns in the pore channel, has limited power and is easy to damage.
The power of the water heater and the wall-mounted furnace is 20-70 kW; the fuel gas and part of air blown by the fan enter the fire grate and are sprayed out from the small holes, after ignition, rich-combustion premixed flame is formed, and the fuel which is not completely combusted and the rest of air sprayed out from the fire grate gap are continuously subjected to diffusion combustion. In the traditional pipe type fire grate, the gas injects primary air to enter a pipe structure and mix, and the premixed gas is ignited and then contacts with secondary air through diffusion to complete the combustion process, so that the structure is simple, the technology is mature, the cost is low, but the emission concentration of CO and NOx is high; the fire grate structure of the thick and thin fire grate is similar to a pipe type fire grate, and NOx is reduced into N by producing reducing atmosphere through staged combustion2The purpose of reducing nitrogen is achieved, but the structure is complex, the cost is high, and although the NOx emission concentration is low, the CO emission concentration is high; the water-cooling fire grate is mainly a combination of a traditional fire grate and a water-cooling copper pipe, reduces flame temperature through heat exchange to realize nitrogen reduction, and has mature technology, high cost, low NOx emission concentration, complex structure and high CO emission concentration; the main body of the full-premixing metal fiber surface combustor is a temperature-resistant metal fiber net which needs to be matched with a full-premixing fan and a valve group for use, and flame is shortenedThe length avoids local high temperatures and reduces combustion time to achieve nitrogen reduction, which, although low in NOx and CO emission concentrations, has the disadvantages of high cost, risk of burner plugging and flashback.
The publication No. CN 108006629 a, "burner and gas water heater with the same", discloses a burner with a first rich combustion chamber, a second rich combustion chamber and a lean combustion chamber, however, only one flame is actually formed in one of the combustion units, the middle part of the flame is lean combustion flame, the two sides are rich combustion flames, the unburned fuel of the rich combustion flames and the surplus oxygen of the lean flame are collected at the tail end of the flame and then are subjected to secondary combustion, and the first blind road and the second blind road are arranged to play a role in separating the rich flame from the lean flame, and cannot separate the whole flame.
In conclusion, the existing mature technology of the combustion assembly with low manufacturing cost has high pollutant emission and is not beneficial to environmental protection; the technology with relatively low pollutant discharge is not beneficial to popularization due to overhigh manufacturing cost.
