RESUMO

The increasing production of biodiesel has caused increased production of residue glycerol. The large amount of glycerin (our glycerol) in the market causes a surplus unusable commercially and industrially, which should give a correct destination. At this point, the porous combustion is characterized by burning within an inert medium, to the pollutants reduce and combustion efficiency. The advantage of inserting an inert solid matrix inside the combustion zone is accurately the recovery of energy released by the reaction. The present work aims mainly the burning of glycerol in a porous media with the supply fuel LPG (Liquefied Petroleum Gas). The difficulty finded in combustion of glycerol is mainly related to their high viscosity at room temperature and the possibility of acrolein formation (2-propanal), potentially carcinogenic substance. In the experimental system developed, the air / LPG and glycerol were inserted into an inert porous burner (eg alumina), where both the glycerol and the LP had controlled its flow. The axial temperature profile of the burner is determined by three B-type thermocouple connected to a data acquisition system. The stabilization of the combustion zone in the porous burner occurred 30 minutes after the beginning of each test, ie, no visible flame combustion. The recorded maximum temperature at the bottom of the porous burner was 1300 C, as acoording the literature does not formation of acrolein in condiction. The emission of pollutants was analyzed, showing a variation in their concentrations of CO (327-350 ppm) and NOx (maximum 18 ppm).
