A combustion system for a boiler

摘要

13 P14/261-0 The present disclosure relates to a system and a method for combustion of solid fuels. The combustion system 10 having burners 180 which supply a mixed flow of fuel and air 5 through a fuel nozzle 40 to the combustion chamber 30 for example of a boiler 1. The mixed flow of fuel and primary air is supplied to the burner 180 through a duct 150 from a pulverizer where the fuel is grinded to the required finesse. The duct 150 is further bends in such a way that one portion is vertical with respect parallel to axis of the boiler 1 A-A is vertical duct 75 and other portion is horizontal duct 80 which is parallel to axis B-B of the fuel nozzle 40.
