Definitions

  • the invention relates to a method for supplying an O2-containing combustion gas for the combustion of lumpy combustible material, in particular waste, in a combustion chamber with an associated grate of an incinerator, in which part of the combustion gas is supplied as a primary gas through the grate and the other part of the combustion gas is supplied at least as a secondary gas in a quantity-controlled manner in at least one jet, the speed of the secondary gas jet being additionally regulated when the amount of combustion gas changes.
  • Such a method is known from DE-PS 632 881, in which the speed of the secondary gas jets entering the combustion chamber is kept constant in order to consume smoke when the total amount of combustion gas changes.
  • nozzles with a variable outlet opening are provided, as shown in FIG. 2 of DE-PS.
  • the adjustment mechanism that changes the outlet opening is contaminated by recirculating dusts, which impairs the function.
  • a method for supplying combustion air in the combustion chamber of a waste incineration plant in which primary air is supplied in a quantity-controlled manner in a plurality of quantity-controlled partial flows to the grate which is divided into a plurality of sectors.
  • primary air is supplied in a quantity-controlled manner in a plurality of quantity-controlled partial flows to the grate which is divided into a plurality of sectors.
  • secondary air is supplied in a quantity-controlled manner in the transition area of the combustion chamber to the radiation draft using nozzles directed towards the grate.
  • thermographic camera records the radiation values emanating from the individual grate sectors and describing the progress of the combustion, which are evaluated in an electronic control and regulating unit, whereupon the regulating flaps of the primary and secondary air guidance are adjusted independently of one another with regard to a predetermined combustion air throughput.
  • Such combustion air routing ensures the O2 cargo required for combustion, but this is also associated with a change in the pulse of the secondary air flow, which means that the pulse flow ratio of the pulse in the transition area of the combustion chamber ascending smoke gas flow to the impulse of the secondary air flow is essentially impaired certain mixing quality, which leads to increased pollutant emissions.
  • the object of the present invention is to provide a generic method in which good combustion with low pollutant emissions from the system is achieved even when the amount of combustion gas changes.
  • the object is achieved in that the pulse of the secondary gas jet is determined and the speed of the secondary gas jet is adjusted to a predetermined pulse of the secondary gas jet when the amount of combustion gas changes.
  • the impulse is determined, on the one hand, by the geometry of the gas space, such as that of the combustion space, into which the beam flows with an intensity matched to it. Furthermore, the impulse is determined by the flow conditions in the gas space, which depending on the mode of operation of the furnace more or less intensely counteracts the achievement of the predetermined range of the jet or the associated homogenization of the rising smoke gases and their enrichment with oxygen with good mixing.
  • the mixing quality and the range of the secondary gas jet are the values determined by a customary flue gas analysis, such as O2, CO, CO2, SO x , NO x , dioxins and / or by thermographical observation of the combustion progress of the combustion material on the grate determined values used.
  • the pulse of the secondary gas jet is kept essentially constant when the amount of combustion gas changes, it is achieved that the range of the secondary gas jet, the mixing quality of the flue gases and the mixing of the secondary gas jet into the flue gas lead to the operating requirements even under low-load operation.
  • An advantageous method is that the pulse of the primary gas flow is determined and the speed of the secondary gas jet is adjusted to a predetermined pulse flow ratio of the pulse of the primary gas flow to the pulse of the secondary gas jet when the amount of combustion gas changes.
  • This methodology takes into account, in particular, the change in the primary gas quantity in a simple manner.
  • the quantity of primary gas added is essentially proportional to the quantity of flue gas, so that the pulse flow ratio of the pulse of the primary gas flow to the pulse of the secondary gas jet allows a qualitative statement about the quality of the mixture or the penetration of the secondary gas jet into the rising flue gas stream.
  • the penetration or mixing ability of the secondary gas jet is inversely proportional to the pulse current ratio.
  • the pulse flow ratio to be regulated thus characterizes a predetermined penetration or mixing behavior of the secondary gas jet, which is essentially retained even when the primary gas quantity and / or the secondary gas quantity changes, in that the speed of the secondary gas jet is adjusted to the predetermined pulse current ratio.
  • the pulse of the primary gas flow is determined and the pulse flow ratio of the pulse of the primary gas flow to the pulse of the secondary gas jet is kept constant with a change in the amount of combustion gas, whereby an essentially constant mixing quality or penetration depth of the secondary gas jet is achieved even with load changes.
  • a further improvement in the mixing in the area near the nozzle orifice can be achieved by swirling the secondary gas jet.
  • a relatively large area of colder combustion chamber atmosphere can be seen at the beginning of the grate, in which there is a risk of dioxin formation.
  • This area can be intensively mixed and enriched with oxygen due to the further improved mixing behavior of the swirled secondary gas jet.
  • the speed of the secondary gas jets is controlled in groups when the secondary gas is supplied by means of a plurality of parallel jets.
  • an additive is added to the secondary gas jet. This enables a precise partial introduction of the additive into the flue gas stream, even under changing operating conditions. Due to the swirling of the secondary gas jet and the recirculation generated thereby, premixing with the secondary gas already occurs in the area near the nozzle.
  • the invention is also directed to a device for supplying an O2-containing combustion gas for the combustion of lumpy combustible material, in particular garbage, in a combustion chamber with an associated grate grate of an incineration plant, with a primary gas supply device below the grate, the primary gas supply device associated control devices and a gas delivery device for quantity-controlled supply of primary gas and with at least one gas nozzle above the fire grate, control devices assigned to the gas nozzle and gas delivery device for quantity-controlled supply of secondary gas, in which in the gas nozzle a control body at least partially blocking the nozzle cross-section with an adjustment device which can be removed from the nozzle for the speed-controlled supply of the secondary gas is arranged and for the speed-controlled secondary gas supply at least one pressure determining the nozzle admission pressure a is provided.
