Means Separating Particles From Exhaust Gas Patents (Class 110/216)
  • Patent number: 10731557
    Abstract: An electrical power generation system includes a micro turbo alternator having combustion chamber, a turbine driven by combustion gases from the combustion chamber and a compressor operably connected to the combustion chamber to provide a compressed airflow thereto. A permanent magnet generator is located along a shaft connecting the compressor and turbine such that electrical power is generated via rotation of the shaft, and a cyclonic dirt separator operably connected to a compressor inlet. The cyclonic dirt separator includes an air inlet, and an air exhaust disposed at opposing ends of a housing. The cyclonic dirt separator is configured to induce circumferential rotation into the airflow entering through the air inlet, and separate the airflow into a clean airflow and a relatively dirty airflow, such that the relatively dirty airflow flows through the air exhaust and the clean airflow is directed to the compressor inlet.

  • Patent number: 10364006
    Abstract: A carbon dioxide cycle power generation system includes storage collectively storing portions of carbon dioxide liquid and gas and a transfer connection selectively directing flow of the carbon dioxide through a turbine. The system cycles between different seawater depths in order to employ at least one of seawater pressure and seawater temperature in creating the carbon dioxide flow. Inlet/outlet control valves on variable volume tanks, positioned below movable pistons within the respective tank, selectively allow seawater into or out of a lower portion of the respective tank below the piston to pressurize the carbon dioxide therein relative to the carbon dioxide within the other tank when at depth rather than near the surface. Inhibited versus uninhibited heat transfer between storage portions and the seawater allows different seawater temperatures at depth and near the surface to create the carbon dioxide flow. Acoustic communications may be driven concurrent with the turbine.

  • Patent number: 9989244
    Abstract: A system can quickly cool and de-pressurize a boiler arrangement under non-normal operating conditions such as loss of plant power. A discharge system injects into the furnace a combined stream of steam from a steam discharge system and ambient air, thereby both cooling components of the boiler arrangement and reducing pressure in the steam/water circuit. This reduces or eliminates the additional cost associated with providing extra capacity in a steam drum and/or an independently powered boiler water pump. The system is particularly useful for quickly cooling the U-beams of a circulating fluidized bed boiler during a black plant condition.

  • Patent number: 8721771
    Abstract: An exhaust gas plume mitigation process and system includes either mixing secondary heat into a moisture rich exhaust gas stream, or diverting a moisture rich exhaust gas stream into a primary exhaust stack having hot exhaust gases flowing therethrough. Moisture rich exhaust gas from a liquid concentrator may be diverted into a high temperature exhaust stack of an engine, a generator, or a flare. The high temperature exhaust gases from the engine, the generator, or the flare raise the temperature of the moisture rich exhaust gas from the concentrator. The high temperature exhaust gases from the engine, the generator, or the flare are also lower in moisture content, so that the moisture rich exhaust gas from the concentrator is diluted by the drier high temperature exhaust gas. As a result, the mixed gas is less likely to develop a moisture plume upon exit to the atmosphere.

The designs consider the impact of decoking options, such as when decoking to a firebox as opposed to a decoking drum. Further, flow and cost considerations are addressed in various embodiments; for example, decoke valves are fairly expensive, and process flows disclosed herein may provide for relocation of the decoke valve to facilitate coke catcher operations while not adding an expensive valve to the overall operating flow scheme.

  • Publication number: 20130300121
    Abstract: A method and system for the conversion of waste into energy in a sealed system where combustion does not take place and the operating pressure prior to the inlet of the steam or power generating equipment is maintained below atmospheric pressure. Destruction of the RDF (refuse derived fuel) is accomplished by subjecting the RDF to a high temperature environment under controlled conditions in a purpose designed and built reactor. The high temperature environment, <5000° C., is achieved through the use of one or more non-transferred plasma torches for generation of plasma gas. The plasma gas exiting the torch and provides the thermal energy for the continual gasification of metallurgic coke configured as a carbon bed in the lower part of the reactor, which acts as a thermal catalyst and this provides the thermal energy for the gasification process.

The refactory material of the reactor and the opaque gases of the reaction environment bring about high power infrared radiation which substantially instantaneously preheats the reactants on input including said reactants being intrinsically transparent to infrared radiation (N2/O2) but rendered opaque and thus absorbers of energy from infrared radiation thanks to dilution with steam. A high efficiency combustor is provided for carrying out the above-stated process.

    Abstract: A method of feeding at least one of light, fine and moist fuel into a furnace of a circulating fluidized bed boiler. Fuel is fed into the furnace through a fuel feed and the fuel is combusted in a turbulent, circulating fluidized bed. A fuel feed area is isolated from the turbulent circulating bed by arranging the fuel feed along at least one channel arranged in a wall of the furnace. Solids of the circulating bed material are introduced onto a first grid section at the bottom of the fuel feed area. The fuel and the solids are mixed and fluidized above the grid section to form a fuel-solids mixture that flows laterally onto a second grid section and a third grid section where the mixture is fluidized. The fluidized bed material is circulated both inside and outside of the furnace. The bed material is separated from the flue gases and returned to the furnace.
