Definitions

  • the present invention relates to power generating systems.
  • micro turbines which are small, recuperated gas turbines have been developed that offer many benefits over conventional small scale power generation technologies. Their principal benefits are reduced costs, increased reliability and availability and also ultra-low emissions.
  • micro turbines In0004] However a significant disadvantage of micro turbines is that they only be operated from gaseous and liquid fuels.
  • a power generating system comprising a combustion chamber for combustion of solid fuel material, a heat exchanger associated with the combustion chamber through we fluid passes to be heated by combustion of the solid fuel material, and a turbine which is driven by the heated fluid to generate power, wherein the heat exchanger includes selectively removable baffles.
  • the turbine is preferably a gas turbine, and may comprise a micro turbine.
  • the heat exchanger may comprise a fluid inlet through which preferably partially pre-heated fluid is introduced into the heat exchanger.
  • Fluid may be introduced into the heat exchanger under compression, and may have been passed through a compressor which may have preheated the fluid for introduction.
  • Fluid may be introduced at a temperature in the range 150-250° C., and preferably 200° C.
  • the fluid is preferably a gas, and may be atmospheric air.
  • the heat exchanger is located in an upper part of the combustion chamber and preferably at or near the top thereof.
  • the heat exchanger may comprise a conduit through which fluid flows to be heated, the conduit dying a tortuous path to facilitate the heating of air therein.
  • the heat exchanger preferably keeps the fluid separate from combustion gases generated during combustion, whilst allowing the gases to pass around the outside of the conduit whereby to heat the fluid passing through the conduit.
  • the baffles may be provided in the heat exchanger to divert combustion gases over the conduit to facilitate beat transfer.
  • the heat exchanger further comprises insulation materials to further improve heat transfer.
  • the insulation material may line the inside of a housing of the exchanger and may comprise ceramic material.
  • the heat exchanger may comprise materials able to resist high temperatures and retain strength and geometry at temperatures up to in the order of 1000° C. whilst providing good conduction of heat, such as exotic stainless steel or other suitable, conductive yet durable material.
  • the heat exchanger is preferably readily dismantled, at least in part, to facilitate cleaning thereof, in particular cleaning of the outside of the conduit for example to remove combustion by-product such as soot and other carbonaceous deposits.
  • the beat exchanger is arranged to allow fluid passing therethrough to be heated to approximate 800-900° C., depending upon the material being combusted.
  • the combustion chamber is arranged to accommodate combustion of a range of solid fuel materials, such as combustible waste, fossil fuels and wood. It is preferable to use sustainable or renewable fuels.
  • heated fluid exits the heat exchanger to be introduced to the turbine to drive the turbine to generate electrical power.
  • a conduit may connect the heat exchanger to the turbine which may be remote from the heat exchanger.
  • Means may be provided to process generated power, such as an inverter/rectifier means.
  • the system may further comprise means to utilise waste gases from the combustion chamber, particularly to use the residual heat in the gases to heat for example an appliance, such as a radiator, before the gases are exhausted from the system.
  • the invention further provides a method of generating power, the method comprising combusting solid fuel material in a combustion chamber to heat fluid passing through a heat exchanger associated with the combustion chamber and including selectively removable baffles, and using said heated fluid to drive a turbine to generate power.
  • the method may comprise the use of a system substantially as defined in any of the preceding twelve paragraphs.
  • FIG. 1 is a schematic representation of a power generating system according to the present invention
  • FIG. 2 is a plan view of a heat exchanger according to the present
  • a heat exchanger may be varied according to desired applications.
  • a plurality of heat exchangers may be used.
  • the system may use any suitable fluid to be heated, such as a gas from a gas source.
  • the system may comprise any number of the aforesaid components and features in any combination.
