Lončene peči - Dimenzioniranje

Ta standard določa izračune za dimenzioniranje Kachelgrundöfen/Putzgrundöfen (lončenih peči / peči iz malte) na podlagi zahtevane nazivne grelne moči peči, kot jo navede proizvajalec. Kachelgrundöfen/Putzgrundöfen (lončene peči/peči iz malte) so zasnovane kot individualne, enkratne konstrukcije. Standard se lahko uporablja za Kachelöfen (lončene peči), v katerih se kuri na polena, ki v enem obdobju shranjevanja toplote porabi eno polnitev z največjim polnjenjem med 10 kg in 40 kg z obdobjem shranjevanja toplote (nazivni čas ogrevanja) med 8 h in 24 h.
Ta standard se uporablja za Kachelgrundöfen/Putzgrundöfen (lončene peči/peči iz malte), opremljene s šamotom kot notranjim materialom, z navidezno gostoto med 1750 kg/m³ in 2200 kg/m³, stopnjo poroznosti od 18 % do 33 % prostornine in toplotno prevodnostjo od 0,65 W/mK do 0,90 W/mK (temperaturno območje od 20 °C do 400 °C).
Ta standard se uporablja za Kachelgrundöfen/Putzgrundöfen (lončene peči/peči iz malte) s stranskim dovodom zraka z notranjim zgorevanjem v zgorevalno komoro in hitrostjo dovoda od 2 m/s do 4 m/s, pri čemer je višina najnižje odprtine vsaj 5 cm nad dnom zgorevalne komore.
Ta standard se ne uporablja za kombinacije z vodnimi izmenjevalniki toplote za centralno ogrevanje ali drugimi elementi, ki absorbirajo toploto, kot so steklene plošče, večje od 1/6 površine zgorevalne komore, odprte posode za vodo itd. Prav tako se ne uporablja za kombinacije z elementi za ogrevanje/kamin v skladu s standardom EN 13229. Poleg tega ta standard ne velja za množično proizvedene montažne ali delno montažne naprave s počasnim sproščanjem toplote v skladu z EN 15250.
OPOMBA:   Čeprav se za namene tega standarda ti izračuni uporabljajo samo za zahteve tega standarda, se lahko isti izračuni uporabljajo tudi za druge namene, npr. za preverjanje ravni emisij in energetske učinkovitosti v primeru kurjenja polen ali lesnih briketov v skladu s priročnikom proizvajalca.

Introduction
This document specifies a calculation method for the dimensioning of Kachelgrundöfen/Putzgrundöfen
(tiled/mortared stoves).
This calculation method for the dimensioning of Kachelgrundöfen/Putzgrundöfen (tiled/mortared
stoves) is based on appropriate literature as well as EN 13384-1, and where empirically determined
correlations are used in addition to physical and chemical formulas.
In case of a calculation method for different interior materials than fireclay the proof of the compliance
of the emission values and the efficiency shall be delivered separately. Also, the empiric data of the
combustion chamber dimensions, the minimum flue pipe length, the burning rate as well as the
combustion chamber temperature and the decrease of the temperature along the flue pipe shall also be
separately determined.

monoxide, nitrogen dioxide, organically bound carbon as well as dust and the energy efficiency.
Complying with the calculations of this document results in emission values less or equal for carbon
