  • the invention also relates to a method for generating heat energy by burning a fuel, in particular biomass, in a boiler, wherein the fuel is burned in a first combustion stage and wherein burned out in the first combustion stage or partially burned fuel, the still a carbon content has, in a second combustion or Ausglühissue further burned or annealed.
  • combustible substances are regularly burned in order to utilize the thermal energy obtained for heating media.
  • the heating takes place with the aid of a heat exchanger, for example an air-water heat exchanger, in which the water is heated by the hot air produced during combustion of the fuels.
  • a heat exchanger for example an air-water heat exchanger, in which the water is heated by the hot air produced during combustion of the fuels.
  • fossil fuels such as petroleum, natural gas or coal
  • renewable raw materials especially wood in the form of wood chips and pellets
  • Such pellet boilers which are also referred to as log wood boilers, are now available in a very large power range of about 5 to 100 kW.
  • biomass is to be understood as meaning renewable raw materials. These include next to wood, especially in the form of wood shavings, wood chips or wood pellets, and cereals also cereal-like substances such as rapeseed or straw, these then preferably in the form of rapeseed cake or straw pellets.
  • a number of problems have arisen in the operation of the wood pellet boilers with grain, so far it has been difficult to achieve operation of the same quality as the intended fuel.
  • the main problems are inferior efficiency due to poorer grain burnout, increased emissions of dust, carbon monoxide, hydrocarbons and nitrogen oxides, which often exceed the allowable limits of the boilers, and increased ash content, which causes problems in ash discharge and leads to problems due to slagging.
  • the flue gases which form during combustion or annealing of the fuels in the combustion or annealing space have lower exhaust gas values due to the somewhat lower temperatures prevailing there Combustion of the fuel in the first combustion stage resulting smoke or fuel gases are supplied and burn out together with these within the flame tube in the prevailing high heat, so that the exhaust gas values of the boiler are hardly negatively affected by the "bad" emission levels from the second combustion stage ,
  • the present invention is therefore based on the Aufgrabe to provide a boiler for the combustion of solid fuels, in particular of biomass, and a method for generating heat energy by combustion of biomass, in the simplest possible way, the emission levels, in particular be further reduced by nitrogen oxides.
  • the primary air supply means comprises an air supply passage and air nozzles formed in a double-walled part of the combustion chamber serving as an air passage.
  • the flue gases resulting from the lower temperature in the burn-out or annealing space during combustion or annealing of the fuel residues, which have inferior pollutant values, together with the flue gases generated during combustion of the Fuel burns on the combustion, burn out within the flame tube in the prevailing great heat.
  • the merging of the flue gases from the first combustion stage and the second combustion stage immediately above the combustion point can adversely affect the combustion of the fuel at the combustion site.
  • the embodiment and arrangement of the primary air supply device according to the invention ensures that the poorer flue gases from the second combustion stage only mix above the primary air supply device with the flue gases formed at the combustion point during the combustion of the fuel. This ensures that the combustion air blown into the first combustion zone from the primary air supply device is not adversely affected by the "worse" flue gases from the second combustion zone, so that the flames at the combustion point can not be “smothered” by the flue gases.
  • the primary air supply device as a hollow body with a plurality of air nozzles on a pipe ring.
  • the air nozzles By an annular arrangement of the air nozzles an optimal supply of serving as combustion air primary air to the burner is possible.
  • the air nozzles are arranged in the hollow body so that air is blown at an angle of about 5 ° to 45 ° to the vertical to the firing point, resulting in a uniform burnout of the fuel on the preferably designed as a burning plate focal point.
  • a second primary air supply device is arranged below the focal point, through which the carbonaceous ash contained in the Ausbrand- or Ausgllickaum combustion air is supplied.
  • the second primary air supply means preferably also has an air supply pipe and a hollow body with a plurality of air nozzles, is blown through the air to the burned or partially burned out glowing fuel in Ausbrand- or Ausglrockaum.

There is thus the possibility that the quantity and / or the pressure of the air which is blown through the first or second primary air supply device onto the fuel at the combustion point or onto the burned out or partially burnt out fuels in the burnout or annealing space , can be adjusted independently.
  • the boiler is associated with a sensor which measures at least one exhaust gas value of the boiler, in particular the residual oxygen content of the flue gases in the exhaust duct of the boiler, then depending on the measured exhaust gas value and / or the pressure of the air is adjusted by the second primary Lunzuschreib landmark.
  • This makes it possible to produce during the combustion of the fuel at the focal point by a correspondingly adjusted air supply via the second primary Lunzuschreib Nurs in the second combustion stage strongly CO-containing flue gas, which, without affecting the combustion in the first combustion stage, together with the flue gas burns out of the first combustion stage in the high heat within the flame tube.
  • An increased CO content of the flue gas causes a desired reduction in the proportion of nitrogen oxides in the flue gas. Measurements have shown that this makes it possible to reduce the proportion of nitrogen oxides (NOx) to less than 500 mg / m 3, based on 13% residual oxygen (reference oxygen).
  • a moving element is arranged in the combustion chamber, which stirs the fuel at the focal point and pushes burned or partially burned fuel over the edge of the combustion, so that these fuel residues fall into the underlying Ausbrand- or Ausglrockaum.

This double-walled region of the flame tube then serves as an air channel through which the secondary air flows from the secondary air supply pipe to the air nozzles or air slots.
  • the formation of the secondary air supply device described above is not absolutely necessary, since not only sufficient combustion air for the combustion of arranged on the combustion fuel can be provided via a corresponding adjustment of the amount of air through the first primary air supply, but at the same time a sufficient secondary air supply during the combustion of the volatile constituents above the combustion point, in particular in the lower region of the flame tube, can be ensured.
  • the object underlying the invention is achieved in that the resulting in the second combustion or Ausglühside flue gases are guided so that they are initially passed past substantially at the first combustion stage, so that the flue gases of the second combustion or Ausglühnote not adversely affect the combustion of the fuel in the first combustion stage, and then supplied to the resulting in the first combustion stage flue gases and burn out together with these at high heat.
