DIN EN 13384-2-2009 烟囱.热和流体动态计算方法.第2部分:适合一种以上加热器具的烟囱(含修改件A2-2009).英文版本DIN EN 13384-2-2009-07
Chimneys - Thermal and fluid dynamic calculation methods - Part 2: Chimneys serving more than one heating appliance (includes Amendment A2:2009); English version of DIN EN 13384-2:2009-07
This part of EN 13384 specifies methods for calculation of the thermal and fluid dynamic characteristics of
chimneys serving more than one heating appliance.
This part of EN 13384 covers both the cases, either
(1) where the chimney is connected with more than one connecting flue pipe from individual or several
appliances in a multi-inlet arrangement or
(2) where the chimney is connected with an individual connecting flue pipe connecting more than one
appliance in a cascade arrangement.
The case of multiple inlet cascade arrangement is covered by the case (1).
This part of EN 13384 deals with chimneys operating under negative pressure conditions (there can be
positive pressure condition in the connecting flue pipe) and with chimneys operating under positive pressure
conditions and is valid for chimneys serving heating appliances for liquid, gaseous and solid fuels.
This part of EN 13384 does not apply to:
- chimneys with different thermal resistance or different cross-section in the various chimney segments.
This part does not apply to calculate energy gain.
- chimneys with open fire places, e.g. open fire chimneys or chimney inlets which are normally intended to
operate open to the room
- chimneys which serve a mixture of fan assisted or forced draught burners or natural draught appliances.
Fan assisted appliances with draught diverter between the fan and the chimney are considered as
natural draught appliances.
- chimneys with multiple inlets from more than 5 storeys. (This does not apply to balanced flue chimney.)
- chimneys serving heating appliances with open air supply through ventilation openings or air ducts,
which are not installed in the same air supply pressure region (e.g. same side of building).
For positive pressure chimneys this part only applies if any heating appliance which is out of action can
be positively isolated to prevent flue gas back flow.
