Abstract: Systems and processes provide for a thermal process to transform sludge (and a variety of other natural waste materials) into electricity. Dewatered sludge and other materials containing a high amount of latent energy are dried into a powdered biofuel using a drying gas produced in the system. The drying gas is recirculated and is heated by the biofuel produced in the system, waste heat (from turbines or internal combustion engines), gas (including natural gas or digester gas) and/or oil. The biofuel is combusted in a boiler system that utilizes a burner operable to burn biofuel and produce heat utilized in a series of heat exchangers that heat the recirculating drying air and steam that powers the turbines for electricity production.

Abstract: Systems and methods for drying or bonding materials are described. A material to be dried or bonded may be passed through a through air dryer (TAD) (or other dryer). Some of the air output by a TAD may be recirculated to be passed back through material. As the air is recirculated, it is heated and mixed to a desired temperature for drying or bonding. A separate hot air injection system may heat ambient air and/or air exhausted by the TAD and inject the heated air into the recirculated air.

Abstract: A fluidized bed system is a single unitary modular system that packages a circulation fan, a fluidized bed, and a dust collection system within a same structure. The structure is formed to include internal ducts to provide fluid communication between the circulation fan, the fluidized bed, and the dust collection system. The fan provides a flow of air via a pressure duct to the fluidized bed. Particulate is separated from particles included on the fluidized bed by the flow of air being uniformly distributed to the fluidized bed. Particulate separated in a disengagement area and suspended in the flow of air is conducted through a particulate clearance space surrounding the dust collection system. The particulate is captured by the dust collection system and conveyed to a location external to the system.

Abstract: A circulation channel circularly supplying air heated by a burner is connected to a drying chamber into which a painted workpiece is supplied. The circulation channel includes a flame holding cylinder surrounding a flame of the burner and a casing surrounding the flame holding cylinder from outside and protrudes further than the flame holding cylinder toward a front end side, opposite to a side of the burner, of the flame holding cylinder. The casing includes a low temperature air inlet port that introduces low temperature air from outside into the casing, an exhaust port that exhausts high temperature air heated by the burner and the low temperature air to the circulation channel, and a mixing mechanism that is formed in the casing and mixes the high temperature air and the low temperature air before the high temperature air and the low temperature air are exhausted from the exhaust port.

Abstract: A method for drying bulk goods, in particular wood fibers and/or wood chips, wherein the bulk goods is continuously dried in a dryer (1), in particular a drum dryer. The vapor-gas mixture flows through the drum dryer (1) in a dryer circuit and is indirectly heated via at least one heat exchanger (4) by a burner waste gas that is heated in at least one burner (5). The drying vapors are supplied to the at least one heat exchanger (4). Upstream, downstream and/or within the at least one heat exchanger (4), at least a partial flow of the drying vapors are branched off to be conducted into the burner (5). The remaining partial flow is conducted to the dryer (1) again. The partial flow of drying vapors to the burner (5) is driven by at least one regulable partial vapor fan (10).
