Abstract: A magnetically actuated axial valve reduces emissions associated with valve stems while retaining a high flow efficiency. In one embodiment, a valve may have inner and outer magnet rings (22 & 23) which may be permanent magnets (12 & 13). Magnetic actuation utilizing N dFeB rare earth magnets (12 & 13) to maximize available torque in rotating an outer magnet ring 180°, thereby forcing synchronous rotation of an inner magnet ring connected to the valve rotor may be provided. A rotary position sensor may provide reliable indication of open and closed valve positions. A valve incorporating a conical sealing interface between rotating and stationary graphite halves to minimize internal leakage by providing a high degree of self-alignment and amplifying the contact force between the two halves is also provided. Methods corollary to the disclosed apparatus are also provided.

Abstract: A method of treating untreated low calorific coal containing moisture and organic volatiles includes feeding untreated coal to a dryer, and drying the coal. The dried coal is subjected to a pyrolyzing step where oxygen-deficient gases are brought into contact with the coal, thereby lowering the volatile content of the coal and producing a stream of pyrolysis effluent gases. The pyrolysis effluent gases are subjected to a separation process to separate lean fuel gases from liquids and tars, wherein the separation process removes less than about 20 percent of the pyrolysis effluent gases as the liquids and tars, with the remainder being the lean fuel gases;. The lean fuel gases are returned to the dryer combustor, the pyrolyzer combustor, or the pyrolyzer.

Abstract: A method and apparatus for upgrading coal and other carbonaceous fuels includes subjecting the carbonaceous fuel to a pyrolyzing process, thereby forming upgraded carbonaceous fuel and a flow of lean fuel gases. Auxiliary fuel is combusted in an auxiliary fuel combustor to produce auxiliary fuel combustion gases, and the lean fuel gases are heated with the auxiliary fuel combustion gases. The heated lean fuel gases are combusted in a lean fuel combustor, thereby producing a gas stream of products of combustion, and at least a portion of the gas stream of products of combustion are directed to the pyrolyzer.
