| description: | Correct air supply control and skilful placing secondary air nozzles increases boiler efficiency and the permitted load of boiler and decreases pollution of heat transfer surfaces and decreases the cost of heat. Despite of a big number of investigations on the biofuel combustion process there are no satisfactory measurements of the temperature and unburned matter distribution in the biofuel flame at different secondary air rate. Especially that problem is critical in case of burning biofuel with alternating moisture. In purpose of elaboration optimal burning regimes of biofuel on grate we must know the temperature and content of unburned matter in flue gases and in flame. Resultant quality of furnace flue gases depends on distribution of mentioned above characteristics. In this project connected with grate burning of biofuels we propose: To find optimal placing and geometry of air nozzles; To investigate the dependence of temperature and unburned matter distribution in flame on secondary air delivery. |
