Definitions

  • the invention relates to a device for burning biological fuels, with a gasification chamber, a grate inclined downward from a fuel inlet, an ash outlet at the lower end of the grate, a gas outlet which leads into a combustion chamber, at least one primary air inlet between the fuel layer and the gas outlet.
  • Such an oven which is known from DE-OS 32 11 735, is not suitable for gasifying problematic materials such as straw, cocoa shells or household waste, since gasification and combustion with low pollutants have reached these substances. Temperatures required, which is above the melting point of the ash of the substances to be gasified in the gasification chamber, so that an air-impermeable layer is formed, which suffocates the gasification process.
  • the object of the invention is to enable the gasification of organic fuels at temperatures which are above the melting point of the ash of the gasified fuel.
  • this object is achieved by one or more above the grate at the level of the glowing fuel layer transversely to the direction of conveyance of the fuel arranged from the fuel outlet to the ash outlet and equipped with outwardly pointing crushing cams, designed as a water-flowed hollow shaft designed as a stirrer.
  • FIG. 1 shows a section through the device with separate combustion chamber and connected storage container
  • FIG. 3 shows a cross section corresponding to FIG. 2 of a further embodiment of the invention.
  • FIG. 4 shows a cross section through a water-cooled glow stirrer.
  • Figures 1 and 2 show cross sections of the device for burning biological fuels, e.g. Sawdust, shavings, wood chips, straw, peat, leaves, cattle manure, household waste.
  • biological fuels e.g. Sawdust, shavings, wood chips, straw, peat, leaves, cattle manure, household waste.
  • a chamotte housing 2 contains a gasification chamber 4 which has a fuel inlet 8.
  • Biological fuel is conveyed from a storage container 30 by means of a screw conveyor 32 through the fuel inlet 8 onto an obliquely downwardly sloping grate 10 which merges into an ash outlet 14 at the lower end.
  • an ash discharge screw 15 is provided transversely to the direction of delivery of the fuel and at later intervals the ash discharges the ash from the housing 2.
  • a gas outlet 7 is provided on the gas side of the gasification chamber 4 and is connected by means of a flame tube 24 opens into a combustion chamber 6, which contains heat exchange devices 26, for example a hot water heater, etc., and has an exhaust gas outlet 27 which is connected either to a chimney of sufficient height or to a chimney fan 28 in order to generate the necessary draft.
  • the grate 10 contains a plurality of stages 11, the height and length of which is dimensioned such that the profile of the fuel bed 5 is essentially such that the fuel is completely converted to ash at the lower end of the grate 10 is.
  • Sensors 9 are attached above the fuel bed 5 and emit control signals to the drive of the screw conveyor 32 when the fuel bed has reached a predetermined profile.
  • the grate 10 is divided into different sections 10a, 10b, 10c in the embodiment shown. These sections 10a, 10b, 10c are separated from one another by air baffles 20.
  • a primary air inlet 18 In front of the air flaps 22 is a primary air inlet 18, which blows primary air into the space 12 below the grate 10 in a metered manner in terms of quantity and pressure by means of a blower (not shown).

  • FIG. 3 shows a cross section of the gasification chamber corresponding to FIG. 2.
  • several glow stirrers 40 are provided at a predetermined distance above the grate, each consisting of a rotatably mounted hollow shaft 42. The glow stirrers 40 continuously tear open the bed on the grate 10 and thereby prevent it
  • the glow stirrers 40 can be driven either at intervals or at certain intervals. Alternatively, the glow stirrers 40 are driven continuously when the system is operating. In this way, slagging of the straw, which quickly stops the air flow through the material to be gasified, is reliably prevented.
  • FIG. 4 illustrates the guide elements 46, which, designed as tines or sheets, guide the cooling water through the breaking cams 44.
