Definitions

  • the invention relates to a furnace with a combustion chamber for solid fuels such as coal and wood, the combustion chamber having two grids arranged one above the other and a filling opening being arranged above the upper grate.
  • Such ovens are known for example from US-PS 4362146.
  • the two grates serve to increase the efficiency when burning using preheated air for primary combustion and secondary combustion.
  • the primary combustion takes place on the top grate.
  • the volatile constituents are first burned and decay e.g. the coal.
  • the volatile components burn in a short time and with great flame formation. After that, the wood breaks down into an ash bed, which pours up the still unburned wood or charcoal that has formed and hinders the further combustion process or charring process.
  • ashes and smaller fuel parts should fall onto the second grate through corresponding opening widths of the upper grate. This is to promote combustion on the top grate.
  • the secondary combustion on the lower grate is used to preheat combustion air, in which the flue gases produced in the secondary combustion are fed to the fuel on the upper grate together with excess combustion air.
  • the invention nevertheless assumes that the known furnace includes a positive approach.
  • the invention is therefore based on the object of changing the known furnace so that it represents a solution which can be used in practice.
  • the upper grate forms a flat fire and the lower grate is part of a filling shaft.
  • the furnace according to the invention can be fired with different fuels, i.e. wood and coal.
  • the wood is placed on the upper grate, the coal in the filling shaft.
  • Charging the top grate with wood on the one hand ensures optimal conditions for the combustion of wood, and on the other hand it prevents excessive loading of the stove with wood due to uncontrolled loading of the filling shaft.
  • the hopper is designed for coal or similar fuels.
  • the filling shaft is loaded either after removing the upper grate and / or by rotating and / or tilting and / or folding the upper grate.
  • the design of the furnace according to the invention makes it possible to meet the requirements of DIN 18890 and DIN 18891 at the same time.
  • the latter regulation applies to stoves for solid fuels
  • DIN 18890 regulates continuous stoves for solid fuels.
  • the stoves differ from continuous fire stoves according to DIN 18890 by the flat firing, the resulting lower fuel consumption and limited long-term fire resistance as well as the use of wood as a suitable fuel and the possibly permissible operation with an open firebox.
  • the use as a stove includes ahead that on the upper grate with wood a permanent fire at rated output of one hour and a 10-hour glow holding can be achieved at low load.
  • the lower grate with filling shaft allows a continuous fire of at least four hours at nominal load and at least 16 hours of continuous fire at low load.
  • a steady state and basic embers must be established to demonstrate operational safety when the firebox is closed for the fireplace.
  • the hottest points are determined under the most unfavorable connection options on the rear and side test wall as well as on the test floor below and in front of the furnace before reaching the basic embers.
  • the temperature in an existing wood storage compartment is also measured at the hottest point.
  • the upper grate is loaded with profiled wood.
  • a quantity of fuel corresponding to a thermal load of 400 MJ / m furnace floor is selected. This amount of wood is given up in two halves and burned down to the embers. The process must be repeated until the surface temperatures to be measured no longer change significantly.
  • the position of the profiled timber is selected so that at least the grate construction is covered and the length is at least 2/3 of the combustion chamber length or 2/3 of the combustion chamber depth.
  • the profile wood is placed evenly on the top grate, optionally layered crosswise.
  • the fuel is burned down with an average delivery pressure for the flue gas of 0.17 1 0.03 mbar to the basic embers present at the start of the test. Different temperatures must not be exceeded during the test.
  • Operating handles must not be more than 35 ° Kelvin when made of metal, 45 ° Kelvin for porcelain or 60 ° Kelvin for plastics.
  • the surface temperature on the floor in front of and under the oven and on 200 mm distant partitions behind and next to the oven, as well as in a wooden storage compartment, if any, should not be more than 60 ° Kelvin above room temperature.
  • the exhaust gas temperature should not exceed 400 °. Heating gas must not escape into the installation room and no embers can fall out of the combustion chamber.
  • the furnace can meet the requirements as a continuous fire furnace by emptying the ash pan after the basic embers have been produced and filling the filling shaft with enough fuel to achieve a four-hour long-term fire at rated heating output based on an efficiency of 70% becomes.
  • the fuel is then burned down to an average of 1.5 to 2 mm water column without interfering with the combustion process, except for the embers present at the start of the test.
  • test for long-term flammability in the case of a small position is again carried out after the steady state and basic embers and emptying of the ash pan have been established and the same amount of test fuel has been given as in the test described above.
  • test fuel By setting an average tensile strength of 0.5 to 1 mm water column, the test fuel is then burned off without interfering with the combustion process. After 16 hours, reheating must be possible without artificially increasing the tensile strength. The same applies to the temperatures on the operating handles and shelves as for stoves.
  • a 2-stage combustion with a first combustion stage on the upper grate and a secondary combustion, the fuel particles falling on the grates underneath, is therefore not the goal, but rather the alternative use of the same furnace both as a stovetop and as a continuous stovetop, which is due to the Construction or the prescribed operation of known ovens was previously excluded.
  • the different solid fuels are assessed according to their emission behavior.
  • Coal especially anthracite and / or thermally treated, pitch-bound hard coal briquettes, are low-smoke fuels.
  • other types of coal such as thermally untreated pitch-bound hard coal briquettes and gas flame coal, can be burned with a sufficiently low emission of dust, soot and tar.
  • Universal long-term favorites of this type are usually designed as filling shaft furnaces. Emissions cannot be avoided in all stoves when burning wood and similar fuels.
  • the permissible emissions are determined using a soot tar number.
  • the dust, soot and tar content is determined by extracting certain amounts of exhaust gas via filter paper. Color spots appear on the preferably white filter paper. A comparison of the resulting color spots with a test scale enables the determination of the soot tar number. A soot tar number of 200 should not be exceeded.
  • the filter paper strip is fed 12 mm after each measurement.
  • the filter paper strip consists of white cotton filter paper with a flow resistance of 40 to 60 mbar (400 to 600 mm water column) with an area-related flow of 3 liters (standard condition).
  • the comparison scale consists of 80 fields of different color tones, which are arranged in a flat, right-angled coordinate system. The fields are numbered 0-9 on the abscissa and letters on the ordinate. From the fuel feed, the soot tar number is measured until the base ember is reached again. To evaluate the measurement, each non-white color spot on the filter paper strip is assigned to a field on the comparison scale that corresponds to its color and is evaluated with the number of the color field. The soot tar number is then the arithmetic mean of the evaluation numbers.
  • the emission peaks are blurred by a longer spout. For example, when trying to burn wood in a filling fire, e.g. a soot tar number of 134 is determined by arithmetically averaging the evaluation number, while the emission peaks are at a soot tar number of 532. These emission peaks appear as black spots on the filter paper. The emission peaks can also be easily recognized by a clear discoloration of the smoke plume emerging from the chimney.
  • the filling chute ends at the filling flap.
  • the second grate for wood provided according to the invention is arranged below the filling flap.
  • the grate arranged in existing ovens under the filling shaft cannot be used as a second grating, because its disassembly and higher arrangement in the filling shaft is either not possible or requires a disproportionately high level of construction and labor. Nevertheless, the height-adjustable arrangement can be seen as a so-called poorer embodiment within the scope of the present invention. This also applies to replacing the filler grate with a grate that has to be placed higher in the filler shaft.
  • a grate that is height-adjustable in this sense results from a gradually expanding filling shaft.
  • a grate can be inserted or removed at each level.
  • the operation of the stove with the upper grate is primarily used to burn wood, the upper grate is also suitable for burning coal or coke with a suitable design of the stove walls.
  • the filling shaft is especially provided for the use of coal or coke or briquettes. The filling shaft can be operated after removing the upper grate, rotating, tilting or folding it up, as well as filling shafts of other known long-term stoves.
  • the upper and the lower grate are arranged parallel to each other.
  • the lower grate is expediently designed as a vibrating grate. The latter is achieved in that the lower grate is rotatably and / or pushed back and forth.
  • the sliding grate is referred to below as sliding grate.
  • the lower grate with a standing grate.
  • the standing grate facilitates ash removal from the furnace.
  • An ash pan is provided under the grate.
  • the oven has a suitable opening on the side or front for ash removal.
  • the standing grate is also accessible through this opening.
  • the lower grate is embedded in the side walls of the oven. I.e. it slides in grooves.
  • the depth of penetration is at least 10 mm, preferably 15 mm. This prevents fuel particles or ash particles from penetrating into the guide of the lower grate and prevents malfunctions caused by the grate becoming jammed.
  • the upper grate it has a larger contact surface than the lower grate. This makes laying wood easier.
  • the larger design of the upper grate means that the upper grate completely covers the lower grate in the vertical projection. The latter results, for example, from Use of a lining in the filling shaft. With the brick lining, an excessive increase in the wall temperature in the filling shaft area can easily be counteracted, which can result from the fact that the burning coal in the filling shaft has contact with the furnace wall. The same is largely ruled out due to the relatively large flat firing of the upper grate.
  • the upper grate is preferably provided as a closed plate or with only a few openings for air to pass through.
  • the ash removal is preferably carried out by swiveling the grate plate. It is sufficient if only part of the grate plate can be swiveled. Then the embers still present can be drawn onto the fixed grate part with a poker or the like, so that when the ash is ashed, the embers do not have to be disposed of and a new fire started. Particularly advantageous conditions result if the rear part of the grate plate is pivotable when the filler flap is on the front. Experience has shown that the vast majority of the ash collected. If there is still embers on top of the ashes, this can easily be pulled forward, while the ashes remain at the back and fall into the filling chute by swiveling the rear grate plate part or into the ash box through the filling chute.
  • the secondary air supply can be formed by openings in the filler flap.
  • the openings are adjustable to regulate this air supply.
  • the construction effort for an adjustable air supply can be reduced by using a single opening, which is moved manually or automatically via a temperature regulator with a flap or a rotary or longitudinal slide.
  • the filling shaft is either partially or entirely designed as a funnel. This results in an advantageous layer of the burning fuel particles on the lower grate.
  • the upper grate is accessible through the loading opening or a suitable opening is provided on the side of the loading opening in the furnace wall.
  • the loading opening is closed by an oven flap, which can be removed to remove the upper grate.
  • This plate can also be provided with viewing windows through which at least the combustion chamber above the upper grate can be seen. In this case, the plate with the viewing windows is preferably located on the front of the furnace, while the loading opening is arranged on the furnace side.
  • the bottom of the furnace - that is, below the ash pan - can be provided with ventilation, especially in connection with radiation protection.
  • the radiation protection is designed as a sheet.
  • the ventilation takes place via openings on the side and / or on the front through which ambient air can penetrate into the space between the ash pan and radiation protection on the one hand and radiation protection and the installation surface on the other.
  • the penetrating and warming ambient air is given the opportunity to climb up at the back of the furnace. That causes a cooling air flow on the furnace floor and increases the heating output of the furnace.
