Abstract: A heat transfer system is provided for a filter house. The filter house is configured to channel air into a turbine engine. The heat transfer system includes at least one of an expansion device and a compressor, a circuit coupled to at least one of the expansion device and the compressor, at least one sensor that detects a parameter of at least one of air channeled through a filter house and the fluid channeled through the circuit, and a controller coupled to the at least one sensor. The controller is configured to selectively control flow of fluid through the circuit to change the parameter of air channeled through the filter house based on the parameter detected by the sensor.

Abstract: The present invention provides a gas conditioning system for processing an input gas from a low temperature gasification system to an output gas of desired characteristics. The system comprises a two-stage process, the first stage separating heavy metals and particulate matter in a dry phase, and the second stage including further processing steps of removing acid gases, and/or other contaminants. Optional processes include adjusting the humidity and temperature of the input gas as it passes through the gas conditioning system. The presence and sequence of processing steps is determined by the composition of the input gas, the desired composition of output gas for downstream applications, and by efficiency and waste minimization.

Abstract: Disclosed herein is a system for simultaneously removing dust and volatile toxic organic compounds. The system comprises a dust collecting unit disposed between an inlet duct and an outlet duct for removing dust, an organic compound removing unit disposed between the inlet duct and the outlet duct for removing volatile toxic organic compounds, and an inlet blower disposed between the dust collecting unit and the organic compound removing unit. The dust collecting unit is made up of a bag filter, which comprises a housing formed in the shape of a box and connected to the inlet duct, a plurality of filtering members, such as cloth or felt, arranged in the housing, and dust collecting layers defined between the housing and the filtering members. The organic compound removing unit comprises an absorbing apparatus for absorbing the volatile toxic organic compounds, and regenerating heaters attached on the outer circumference of the absorbing apparatus.

Abstract: A method and apparatus are disclosed for mixing sewage sludge with spent water-softener lime in a ratio of approximately 10:1 on a wet basis. The mixture is introduced to a rotary pre-dryer kiln and a rotary combuster kiln to kill pathogens. An ash by-product and gases are thereby produced. The ash by-product can be disposed of at much less cost or can be incorporated in a variety of applications such as an aggregate substitute.

Abstract: Apparatus for the treatment of volatile material(s) in contaminated material(s) including a retort assembly which includes a rotatable retort disposed at least partially within a combustion chamber with a heater to indirectly heat the contents of the rotatable retort. A feeder feeds the contaminated material(s) to the retort. The apparatus further includes a pathway for passing contaminated material(s) to the retort and a conduit for passing the combustion gases from an afterburner to the retort assembly to provide additional heat for heating the contaminated material in the retort. The apparatus may also include a high temperature filter which can filter the volatiles before entering the afterburner.
