DIN EN 15544:2009-12 EN 15544:2009 (E) 4 Introduction This standard specifies a calculation method for the dimensioning of Kachelgrundfen/Putzgrundfen (tiled/mortared stoves)
20、 based upon the required nominal heat output of the stove as declared by the producer. If the calculations of this standard are observed, the minimum energy efficiency of 78% and the emission values of carbon monoxide 1 500 mg/mn (1 000 mg/MJ), nitrogen dioxide 225 mg/mn (150 mg/MJ), organically bou
21、nd carbon 120 mg/mn (80 mg/MJ) and dust 90 mg/mn (60 mg/MJ) will be observed too. This calculation method for the dimensioning of Kachelgrundfen/Putzgrundfen (tiled/mortared stoves) is based on appropriate literature as well as EN 13384-1, and where empirically determined correlations are used in ad
22、dition to physical and chemical formulas. NOTE In case of a calculation method for different interior materials than fireclay the proof of the compliance of the emission values should be delivered separately. Furthermore the empiric data of the combustion chamber dimensions, the minimum flue pipe le
23、ngth, the burning rate as well as the combustion chamber temperature and the decrease of the temperature along the flue pipe should also be determined. DIN EN 15544:2009-12 EN 15544:2009 (E) 5 1 Scope This standard specifies calculations for the dimensioning of Kachelgrundfen/Putzgrundfen (tiled/mor
24、tared stoves) based upon the required nominal heat output of the stove as declared by the producer. The Kachelgrundfen/Putzgrundfen (tiled/mortared stoves) are of individual one-off construction design. The standard can be used for log wood fired Kachelfen (tile stoves) that burn one fuel load per s
25、torage period with a maximum load between 10 kg and 40 kg and a storage period (nominal heating time) between 8 h and 24 h. This standard is valid for Kachelgrundfen/Putzgrundfen (tiled/mortared stoves) equipped with fireclay as interior material, with an apparent density between 1,750 kg/m and 2,20
26、0 kg/m, a degree of porosity from 18 % up to 33 % by volume and a heat conductivity from 0,65 W/mK up to 0,90 W/mK (temperature range 20 C to 400 C). This standard is valid for Kachelgrundfen/Putzgrundfen (tiled/mortared stoves) with sidewise combustion air supply of the combustion chamber and an in
27、flow speed from 2 m/s to 4 m/s, whereas the height of the lowest opening is at least 5 cm above the bottom of the combustion chamber. This standard is not valid for combinations with water heat exchangers for central heating or other heat absorbing elements like glass plates greater than 1/6 of the
28、combustion chamber surface, open water tanks, etc. It is also not valid for combinations with heating/fireplace elements according to EN 13229. Furthermore this standard is not valid for mass-produced prefabricated or partly prefabricated slow heat release appliances according to EN 15250. NOTE Alth
29、ough for the purposes of this standard these calculations are applicable only to the requirements of this standard, the same calculations can be used for other purposes, e.g. to verify emission levels and energy efficiency in case of burning log wood or wood briquettes according to the producers man

NOTE 2 The specified storage period can vary between 8 h and 24 h. 4.2.2 Minimum load The minimum load shall be calculated as
41、50 % of the maximum load as follows: BBmin5,0 mm = (2) where mBis the maximum load (kg); mBminis the minimum load (kg). 4.3 Design of the essential dimensions 4.3.1 Combustion chamber dimensions NOTE Designing the dimensions of the combustion chamber serves two main purposes: firstly to ensure that
42、sufficient room is available to contain the fuel needed to be charged and secondly that the requirements for clean combustion are met. DIN EN 15544:2009-12 EN 15544:2009 (E) 8 4.3.1.1 Combustion chamber surface The dimension of the combustion chamber surface shall be calculated as follows: BBR900 mO

For the calculation of the combustion chamber surface all its walls, the ceiling and the base including the area of the combustion chamber opening and the combustion chamber exit for the flue gas shall be rega
44、rded equally i.e. calculated as if there were no combustion openings or exits. 4.3.1.2 Combustion chamber base The combustion chamber base can be varied between a minimum and a maximum value. The minimum value results from the requirement that at maximum load a height of the fuel of 33 cm shall not
45、be exceeded. Therefore the base shall be calculated using 100 cm per kg fuel as follows: BBRmin100 mA = (4) where mBis the maximum load (in kg); ABRminis the minimum combustion chamber base (in cm2). The maximum area of the base of the combustion chamber shall be defined as a result of equations (3)

When the base is square, the proportion of length to width can be varied from 1 to 2, but there shall be a
47、minimum width of 23 cm. 4.3.1.3 Combustion chamber height The minimum combustion chamber height shall be defined as follows: BBR25 mH + (6) where mBis the maximum load (in kg); DIN EN 15544:2009-12 EN 15544:2009 (E) 9 HBRis the combustion chamber height (in cm).
