Definitions

  • the invention relates to a device for burning oxidizable Components in a carrier gas to be cleaned, comprising a gas inlet, a burner with subsequent flame tube, which in a bottom and side walls comprehensive main combustion chamber opens, one on the bottom wall combustion chamber outlet, preferably on the opposite side of the main combustion chamber Heat exchanger and a gas outlet.
  • the invention relates to a method for burning oxidizable Components in a carrier gas to be cleaned in a device comprising a main combustion chamber starting from the flame tube and delimited by bottom and side walls, in the cleaned gas from the bottom wall towards a preferably coaxial deflected to the flame tube arranged combustion chamber outlet becomes.
  • a device of the type described above is e.g. B. EP 0 235 277 B1.
  • the so-called high-speed mixing chamber opens Flame tube in the main combustion chamber, the cross section of which is larger than the free flow cross section in the high-speed mixing room.
  • the main combustion chamber extends on the outside along the high-speed mixing chamber, which is designed as a tube is in an annular shape coaxial with the high-speed mixing space Pass channel, which in turn into a high-speed mixing room and others arranged partially around the annular channel passes channel-like annular space in which a heat exchanger is arranged, the pipes are bent outwards at their colder ends.
  • the main combustion chamber extends, its flow cross section is also larger than that of the high-speed mixing room, completely along the high-speed mixing space and then preferably opens radially in a heat exchanger, which is preferably arranged in an annular channel is.
  • the gas leaves the high-speed mixing room in the form of a free jet.
  • This beam hits the bottom wall of the main combustion chamber and is there according to the flow geometry of a baffle plate flow distributed rotationally symmetrically.
  • High centrifugal forces cause the gas both along the bottom wall and after a further deflection like a Ring jet flows axially along the inner surface of the side wall of the combustion chamber.
  • the cross-sectional area of this ring beam takes along the side wall of the Main combustion chamber to the combustion chamber outlet only slightly, so that between the ring jet and the outer wall of the high-speed mixing chamber forms a stationary vortex area.
  • the present invention is based on the problem of an apparatus or a method of the type described above so that the volume of the main combustion chamber ideal for burning the oxidizable components in the carrier gas is being used.
  • this task is essentially solved by that at least one flow-guiding element is installed in the main combustion chamber through which the flame tube leaves and in the direction of the combustion chamber outlet flowing gas is distributed over the entire cross section of the main combustion chamber, a rectified flow of the gas arises and the combustion over the cross section of the main combustion chamber takes place evenly.
  • the guide element can be a guide plate, a perforated plate and / or a guide ring or similar flow distribution device as e.g. Cone-shaped reflector cones Baffle plates and vanes. At least two guide elements are preferably shown in FIG the main combustion chamber.
  • the or the guide element are preferably between the outlet opening of the flame tube and the bottom wall of the main combustion chamber.
  • the guiding elements can also be arranged coaxially around the flame tube or guiding elements both between the outlet opening of the flame tube and the bottom wall and coaxially to Flame tube to be arranged.
  • the teaching of the invention distributes the flow of the Gas mixture in the entire main combustion chamber.
  • the device according to the invention In particular, there is the advantage that there is a significant reduction in the temperature of the skin's combustion chamber or a reduction in the main combustion chamber volume with the same Residual concentration of oxidizable components in the cleaned carrier gas or a reduced residual concentration while maintaining the main combustion chamber temperature and constant main combustion chamber volume can be achieved.
  • the invention is characterized in that that leaving the flame tube and flowing in the direction of the combustion chamber outlet Gas is distributed over the entire cross-section of the main combustion chamber in such a way that there is a rectified flow of gas and combustion takes place evenly over the cross-section of the main combustion chamber.
  • the redirected Gas essentially free of turbulence and backflow to the combustion chamber outlet be performed. This ensures that the combustion chamber is fully utilized and prevented Mixing more purified gas with less purified gas.
  • the main combustion chamber (24) is in a first one Section (23) with a large cross-sectional area and a second section (25) with divided small cross-sectional area.
  • the first section (23) is annular to the axis (18) of the device (10) and is delimited by the end wall (16) Sections (17) of the outer casing (12) and through an intermediate wall (50).
  • the second section (25) of the main combustion chamber is an annular space around the flame tube (22), starting from the intermediate wall (50) and ending in a further annular space (28), in the heat exchanger tubes (30) of a cross-countercurrent heat exchanger (32) concentric to the axis (18) of the device (10) and thus also concentric to the flame tube (22) are arranged.
  • guide elements (40) are located in the main combustion chambers (24), (42), (44) arranged, which cause the entire cross-sections the main combustion chambers (24) or across the cross sections of the individual sections of the main combustion chambers an even, in essentially rectified flow is present.
  • the guide elements can both by low resistance and lead the flow through large form resistances.
  • the examples are Guide elements (40) and (42) in the form of a guide ring or guide plate a low form resistance, whereas guide elements (44) in the form of Perforated sheets or resistance grids or in the form of panels a large one Form resistance.
  • the shape of the guide elements in particular the guide elements (40) and (42), must be such that partial volume flows of the rotationally symmetrical flow onto the floor (21) of the main combustion chamber (24) and shear off Deflection by 90 ° in the direction of the combustion chamber outlet (26) is effected.
  • the guide element (44) in the form of a perforated plate, resistance grille, an orifice or the like, which surrounds the end region of the flame tube (22) in each of the exemplary embodiments, represents a high flow resistance which, owing to the high speeds in free cross-sectional areas present in the guide element, results in a distribution of one side on Outer jacket of the main combustion chamber (24) formed flow on the entire cross-sectional area of the main combustion chamber (24).
  • Raw gas laden with pollutants i.e. containing oxidizable components Carrier gas
  • the gas inlet designed as an inlet connection (36) into the device (10) is concentric with the flame tube (22) arranged heat exchanger tubes (30) guided, leaves in one arranged coaxially to the burner (19) and from the end wall (14) limited chamber (46) the heat exchanger (32) and at least partially passed the burner (19).
  • While flowing through the Heat exchanger (32) is preheated by absorbing heat via the Heat exchanger tubes (30) emerging from the main combustion chamber (24) and gas flowing around the heat exchanger tubes (30).
  • Part of the preheated pollutant-laden raw gas reaches the Flame of the burner (19) in contact and serves as a combustion gas. Of the other part flows past the burner (19) or the flame.
  • the raw gas with the already reacting pollutants occurs in the first section (23) of the main combustion chamber (24) and is there by the guide elements acting as flow-guiding internals (40) and / or (42) and / or (44) on the entire flow cross section the main combustion chamber (24) distributed so that a rectified Flow arises and combustion over the cross-section of the main combustion chamber done evenly.
  • the cleaned carrier gas is then around the heat exchanger tubes (30) Pipe bundle heat exchanger (32) guided, gives heat to what is to be cleaned Carrier gas and is also designed as a gas outlet (38) headed.
