Embodiment Construction

[0077] See attached drawings and see first figure 1 , figure 1 Showing a first embodiment of the invention, this figure shows a side view of a spreader 10 according to one embodiment of the invention. The spreader 10 comprises an upper inlet 11 forming part of a chute 12, a main body in the form of a cylindrical member 13, an outlet 14 through a side wall 15 of the boiler, and an outlet 14 through which the bagasse is pushed through the spreader from the upper inlet 11 through the outlet 14. A vortex motion is applied to a device 16 on the bagasse.

[0078] The chute 12 is generally generally rectangular when viewed in plan, but may be of any desired size and have other shapes if desired.

[0079] The chute has an open top including the inlet 11 . Bagasse or other solid fuel enters the chute 12 through the inlet 11 . If bagasse is used, a bagasse feeder (not shown) is typically provided to supply bagasse into the chute 12 . The bagasse flows down from the chute 12 under t...

Abstract

An apparatus to pass a solid fuel into a furnace, the apparatus compries: an inlet to allow the fuel to pass into the apparatus, an outlet to allow the fuel to pass out of the apparatus, a main body portion between the inlet and the outlet, means to propel the fuel through the apparatus, and, means to impart a swirling motion to the fuel prior to the fuel passing through the outlet. The apparatus can be used as a swirler spreader to propel bagasse into a boiler / furnace.

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...
