Experimental studies of infrared burners of a micronizer functioning with biomethane

To increase the shelf life of grain crops, heat treatment with a micronizer is used. For testing, a block heating burner with radiant nozzles was developed and improved to determine the permissible content of carbon dioxide in the purified biogas when fed to a gas infrared heating system with burners. The operability of the infrared burner ГИК-8 on purified biogas with a CO2 content of 0.234.0% has been established. The temperature of the heating surface of the ГИК-8 burner on gas mixtures with a CO2 content of 18-34% is 900-950˚С, which does not differ from the nominal temperature when operating on natural gas. The possibility of ignition of a cold burner ГИК-8 at 33% CO2 content in the purified biogas has been determined.
