A fuel material processing system includes a hopper assembly configured to receive a fuel material. A drying system is configured to remove moisture from the fuel material to generate a dried fuel material. A material delivery system is configured to provide the dried fuel material to a combustion system.

At least one aspect of the technology provides a self-contained processing facility configured to convert organic, high water-content waste, such as fecal sludge and garbage, into electricity while also generating and collecting potable water.

An object of the present invention is to provide a pulverized coal drying system for a pulverizer, a pulverized coal drying method therefor, a pulverized coal drying program, a pulverizer, and an integrated gasification combined cycle capable of stably drying a carbonaceous feedstock irrespective of the type of the carbonaceous feedstock to be used. There is provided a controller (50) of a pulverizer (10) that dries a supplied carbonaceous feedstock by using a drying fluid and includes a flow rate controller that controls the flow rate of the drying fluid within upper and lower limits of the flow rate of the drying fluid that are set to dry a plurality of types or the carbonaceous feedstock having different moisture contents in such a way that the temperature of the drying fluid discharged from the pulverizer (10) approaches a target temperature.

At least one aspect of the technology provides a self-contained processing facility configured to convert organic, high water-content waste, such as fecal sludge and garbage, into electricity while also generating and collecting potable water.

A method of operating a furnace having a firing system is disclosed. The method includes providing a solid fuel to a sieve; separating the fuel into a portion and a second portion; providing a first portion of a flue gas to a first fuel dryer comprising a first duct; providing the first portion of fuel to the first duct, and drying the first portion of fuel therein; conveying the first portion of fuel through the first duct to the furnace; burning the first portion of fuel with firing system; conveying the second portion of fuel and a second portion of the flue gas to a second fuel dryer in a lower portion of the furnace, providing the second portion of fuel to a mill; pulverizing the second portion of fuel with the mill; conveying the second portion of fuel to the furnace; and burning the second portion of fuel.

Moisture is removed from particulate material using an apparatus comprising a dryer having a drying chamber for directing a flow of gas-entrained particulate material between first and second ends of the drying chamber. The dryer is configured for directing gas under pressure into the drying chamber, for interacting with a flow of gas-entrained particulate material within the drying chamber. The dryer comprises a body of modular construction, which defines a plurality of guide passages arranged for fluid communication between the drying chamber and a source of gas under pressure. The body of modular construction comprises a plurality of discrete annular elements, arranged in series, one adjacent another, each having a body defining a central aperture, and wherein the annular elements are arranged together with the central apertures aligned.

Process of producing a treated coal and combusting the treated coal, by heating the coal to remove volatiles and drying the product to produce a treated coal containing carbon and hydrogen. The treated coal is combusted by introducing a slipstream of natural gas alongside the treated coal in a quantity sufficient to sustain a stable burn in an industrial boiler configured to burn bituminous coals.
