Abstract: The present invention harvests and utilizes fluidized bed drying technology and waste heat streams augmented by other available heat sources to dry feedstock or fuel. This method is useful in many industries, including coal-fired power plants. Coal is dried using the present invention before it goes to coal pulverizers and on to the furnace/boiler arrangement. Coal can be intercepted on current coal feed systems ahead of the pulverizers. Drying fuel, such as coal, is done to improve boiler efficiency and reduce emissions. A two-stage bed utilized in the process first “pre-dries and separates” the feed stream into desirable and undesirable feedstock. Then, it incrementally dries and segregates fluidizable and non-fluidizable material from the product stream. This is all completed in a low-temperature, open-air system. Elevation of fan room air temperature is also accomplished using waste heat, thereby making available to the plant system higher temperature media to enhance the feedstock drying process.

This invention is especially useful for drying coal for an electricity generation plant.

Abstract: A process and a business method for converting wood waste to charcoal have been invented. Multiple high productive thermo energy simplified bio-cokes furnaces create an outlet discharging the earned volatile gas and the wood tar from the carbonization device. By taking back the gas and the wood tar mixed with the air into the furnace, the present invention produces evenly distributed heat with higher energy productivity. The present invention adopts different Coefficients of Thermal Expansion (CTE) for the top opening zone and the carbonization chamber, to avoid transmittal of oxygen from outside the furnace. Charcoal produced with a reduced energy use by the present invention can replace bio-cokes produced from general waste incineration. Through the creation of higher carbon charcoal, the present invention introduces a source of environment-friendly, cost effective and sustainable heat use. Accordingly, the present invention proposes promising business models both to the suppliers and the consumers.

Abstract: Fine coal is cleaned of its mineral matter impurities and dewatered by mixing the aqueous slurry containing both with a hydrophobic liquid, subjecting the mixture to a phase separation. The resulting hydrophobic liquid phase contains coal particles free of surface moisture and droplets of water stabilized by coal particles, while the aqueous phase contains the mineral matter. By separating the entrained water droplets from the coal particles mechanically, a clean coal product of substantially reduced mineral matter and moisture contents is obtained. The spent hydrophobic liquid is separated from the clean coal product and recycled. The process can also be used to separate one type of hydrophilic particles from another by selectively hydrophobizing one.

Some or all of the torrefied product can be recovered, or some or all of the torrefied product is then directed to a separate carbonization reactor coupled with a reactor burner. Carbonization serves to remove most of the remaining VOCs which are used as a gaseous fuel input to the dryer.
