Experimental studies on the adaptation of micronizer infrared burners for biomethane

To destroy pathogenic microflora, increase digestibility and nutritional value, cereals, which are part of compound feeds, are subjected to IR processing in a micronizer. However, in order to transfer micronizer burners from natural gas to biogas generated during anaerobic methane digestion of livestock complex waste, it was necessary not only to purify biogas from carbon dioxide, hydrogen sulfide and other associated gases, i.e. to obtain biomethane, but also to improve the design of the module heating burners with radiating nozzles. The efficiency of the GIK-8 infrared radiation burner on purified biogas with a CO2 content of 0.2-34.0% was experimentally established, and an improved burner design for a micronizer with adaptation to its operation on biomethane was developed. The geometric dimensions and shape of the micronizer infrared burners with the adaptation of their operation on biomethane are specified. The efficiency of the GIK-8 infrared radiation burner on purified biogas with a CO2 content of 0.2-34.0% was established. The temperature of the heating surface of the GIK-8 burner in gas mixtures with a CO2 content of 18-34% is 900-950 °C, which does not differ from the nominal temperature when operating on natural gas. The possibility of ignition of the GIK-8 cold burner at 33% CO2 content in purified biogas was determined.
