摘要： A dew point corrosion resistant heat exchanging system having a plurality of hollow heat transferring tubes through which cooler ambient air or hot combustion product gases flow. The other of the air or gas flows across the outer surfaces of the tubes, and heat is transferred from the hot gases to the ambient air, thus heating the air. A portion of the tubes includes an inner liner forming an air pocket chamber between the liner and the outer wall of the tube. The air pocket chamber provides heat transfer advantages that maintain the tubes at a temperature above the dew point of the gases in the system, thus inhibiting corrosion of the tubes.

摘要： 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.

摘要： A burner and methods of using the burner. The burner produces a flame from combustion air and fuel gas. Flue gas, also produced, can be withdrawn and recycled to the burner. A cooling or condition gas, such as ambient air, may be mixed with the flue gas to reduce its temperature. The burner may also utilize a stage injection so that a portion of the produced flue gas is recycled internally.

摘要： A heat exchange apparatus for removing magnetic particulates from a gas stream, including a rotating element basket having a regenerative heat exchanger and at least one magnetic element. A method of removing magnetic particulates from a gas stream, including heating the regenerative heat exchanger during a first portion of a cycle as a segment of the rotating element basket passes through a first zone wherein contact is made with a flue gas thereby accumulating any magnetic particulates as they are attached to the magnetic element. Then cleaning a portion of the magnetic element during a second portion of the cycle. And cooling the regenerative heat exchanger and simultaneously heating an inlet air stream during a third portion of the cycle as the segment of the rotating element basket passes through a third zone wherein fluidic contact is made with the air inlet stream.

摘要： The invention relates to a staggered firing for combustion of wet charge materials, consisting of the following steps: pre-combustion designed as a fluidized bed firing, heat transition in a heat exchanger, dust precipitation, and post-combustion. The staggered firing is characterized in that during the heat transition in the heat exchanger, exhaust gases from the pre-combustion are cooled and combustion air for pre-combustion is heated and then supplied to the pre-combustion.

摘要： A method and apparatus for heating a furnace using a burner system having first and second burner assemblies, each including a burner and a regenerative media bed, the method including operating the first burner assembly in a firing mode and the second burner assembly in a regeneration mode, switching the first burner assembly from the firing mode to the regeneration mode and the second burner assembly from the regeneration mode to the firing mode, and operating the second burner assembly in the firing mode and the first burner assembly in the regeneration mode. The burner assembly in the firing mode may be fired in either a first operating mode where the burner is supplied with preheated low calorific fuel and the burner is supplied with oxidizing gas or a second operating mode where the burner is supplied with preheated oxidizing gas and the burner is supplied with high calorific fuel.

摘要： A boiler facility includes a boiler having a combustion chamber in which a burner is installed, a fuel pipe for supplying fuel to the burner, an air duct for supplying air sucked by a blower to the boiler, an oxygen supplier having an oxygen pipe connected to the air duct and a flow rate controller provided in the oxygen pipe, and a control unit. The control unit sets an air amount that is smaller than the reference air amount for burning the fuel, and controls the blower so that the set air amount is supplied to the boiler. Further, the control unit sets an oxygen amount for fuel combustion, and controls the flow rate controller so that the set oxygen amount is supplied to the air duct.

摘要： The present device is a fluid bed regenerative thermal oxidizer configured to minimize dead spaces within it and eliminate the need for complex valve systems, which are typically required to move treated and untreated air across fixed beds. The present device can be a fluid bed regenerative thermal oxidizer comprising a vertical stack having a combustion chamber near its interior center and desorber shelves located within the vertical stack above the combustion chamber and adsorber shelves located within the vertical stack below the combustion shelves. Ceramic spheres can be used as heat sinks that flow from the desorber shelves, around the combustion chamber and onto the adsorber shelves and then back to the desorber shelves. In this way heat from the combustion can be captured by the heat exchange material on the desorber shelves and released to preheat untreated air on the adsorber shelves.
