Abstract: The present disclosure relates to a system and a method for combustion of solid fuels. The combustion system includes burners which supply a mixed flow of fuel and air through a fuel nozzle to the combustion chamber for example of a boiler. The mixed flow of fuel and primary air is supplied to the burner through a duct from a pulverizer where the fuel is grinded to the required finesse. The duct 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 and other portion is horizontal duct which is parallel to axis B-B of the fuel nozzle.
