Estimating the term…
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 to improve boiler efficiency and reduce emissions. This is all completed in a low-temperature, open-air system. Also included is an apparatus for segregating particulate by density and/or size including a fluidizing bed having a particulate receiving inlet for receiving particulate to be fluidized. This is useful for segregating contaminants like sulfur and mercury from the product stream.
A method for heat treating a feed, byproduct, or product stream within an industrial plant operation that produces at least two different types of waste heat, such method comprising:
A method for reducing the moisture of a particulate material within an industrial plant operation that produces at least two sources of waste heat, such method comprising:
A method used within an industrial plant operation for heat treating a feed, byproduct, or product stream comprising a heat input, wherein a source of waste heat at a temperature of about 300° F. or less supplies the heat input further comprising:
