Abstract: A serpentine waveguide applicator for exposing a material to microwave energy for hearing, drying, or curing. A conveyor transports the material through aligned slots formed in facing sides at consecutive waveguide passes of the serpentine array. Each pass has a ridged waveguide structure with ridges in each corner of the otherwise rectangular waveguide. The ridges make the interior cross section of the waveguide passes cruciform and direct microwave energy away from the slots to reduce arcing, crosstalk, and leakage.

Abstract: A T-junction microwave applicator and a method for making a T-junction microwave applicator with a microwave source supplying electromagnetic energy through a junction arm to a pair of collinear arms extending in opposite directions from their junction with the junction arm. The two collinear arms form a main waveguide terminated in end walls in which entrance and exit ports are formed for a conveyor to convey material to be heated through the main waveguide for exposure to electromagnetic energy. A rectangular conductive ridge in the wall of the main waveguide opposite the junction arm extends the length of the applicator. A cylindrical tuning bar spanning the junction is positioned vertically in a plane perpendicular to the axis of the main waveguide to maximize power transfer to the material to be heated.

Abstract: A microwave applicator system exposing a material flowing through multiple applicator stages to a different radial heating pattern in each stage for uniform heating. A two-stage applicator system has a pair of back-to-back applicators, each having offset, outwardly jutting walls on opposite sides of a material flow path through a microwave exposure region. The offset, cylindrical juts formed in the wide walls of the generally rectangular waveguide cause hot spots to occur in material flowing through and between the narrow walls of the waveguide at opposite radial positions on a radial line oblique to the longitudinal direction of the waveguide. Uniform product heating can be achieved by directing a material sequentially through these two applicators in opposite directions.

Abstract: A method for drying coal using microwave energy to achieve a controlled aggregate moisture content target range without starting combustion or degrading the coking qualities of the coal. Coal feed stock is first separated into fine grade coal and one or more larger grades. The fine grade coal is loaded onto a conveyor as a bed of fixed depth. The fine grade coal is conveyed continuously through a microwave-energized heating chamber for drying. The fine grade coal is dried sufficiently so that when it is combined with the larger grade coals, the moisture content of the aggregate is within a target moisture content range. By volumetrically and uniformly heating the coal, the microwave heating chamber boils away the water without heating the coal itself above about 90°C. In this way, the coal does not combust or oxidize, and its coking qualities are retained.

Abstract: Heating and drying devices including generally rectangular waveguide applicators forming exposure chambers for uniformly heating materials. Material to be heated enters and exits a microwave exposure region of the chamber through entrance and exit ports at opposite ends of the chamber. Various techniques are used to achieve uniform or preferred heating effects. Exemplary techniques include: 1) passageways jutting outward of chamber side walls; 2) ridges formed along top and bottom walls of the chamber; 3) metallic blocks extending along the length of the conveyor near the edges of the belt; 4) corner blocks to enhance heating of material in the middle of the chamber; 5) dormers formed in the top or bottom waveguide walls; 6) tapered waveguide segments; 7) virtual short plates and virtual waveguide walls; and 8) multiple-stage heaters having more than one chamber.
