Description

technical field

[0001] The present invention relates to an improvement to an air-powered spreader for spraying solid fuels, usually containing a large amount of moisture, into boilers or furnaces, the improvement including turning the vortex motion Applied to solid fuel. The invention has particular application, but is not limited to, in suspension fired sugar industry boilers which burn bagasse or sugarcane plantation waste as solid fuel by pneumatically feeding the bagasse to the boiler furnace with a vortex motion To improve the combustion performance of boiler combustion. The invention will be described with reference to its application in the sugarcane industry, but the invention need not be limited thereto but can be used in any spreader grate type industrial boiler with any type of solid fuel like biomass fuel . Background technique

[0002] In the sugar industry, bagasse is burned in spreader grate industrial boilers as the residue of sugarcane fibers remaining af...
