Chimneys - Thermal and fluid dynamic calculation methods - Part 1: Chimneys serving one heating appliance

This European Standard specifies methods for the calculation of the thermal and fluid dynamic characteristics of chimneys serving one heating appliance.
The methods in this part of this European Standard are applicable to negative or positive pressure chimneys with wet or dry operating conditions. It is valid for chimneys with heating appliances for fuels subject to the knowledge of the flue gas characteristics which are needed for the calculation.
The methods in this part of this European Standard are applicable to chimneys with one inlet connected with one appliance. The methods in Part 2 of this European Standard are applicable to chimneys with multiple inlets and one inlet with multiple appliances. Part 3 describes methods for the development of diagrams and tables for chimneys serving one heating appliance.

This draft amendment is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 166.

This draft amendment A1, if approved, will modify the European Standard EN 13384-1:2015. If this draft becomes an

amendment, CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for

inclusion of this amendment into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other

language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC

Management Centre has the same status as the official versions.

1 Modification to 1, 3, 4, 5, 6, 7, 8, 9 and Annex B
Replace
“heating appliance”
“combustion appliance”.
2 Modification to 5.5.2
Replace Clause 5.5.2 with the following text:
"5.5.2 Flue gas mass flow and combustion air mass flow

5.5.2.1 Flue gas mass flow and combustion air mass flow at nominal heat output of the

combustion appliance

For the calculation of pressure and temperature values according to relationships of Formulae (1), (2),

(2a), (3), (4), (5), (5a) and (6) the flue gas mass flow and combustion air mass flow at nominal heat output

conditions for the combustion appliance shall be obtained.

If the data are not available the flue gas mass flow, combustion air mass flow and the volume

concentration of CO can be determined from the formulas in Tables B.1, B.2 or B.3.

If the chimney is connected to a multi-fuel combustion appliance the calculation and dimensioning should

be carried out by considering all the fuels suited to the appliance.

In the case of combustion appliances with a draught diverter the flue gas mass flow downstream of the

draught diverter shall be used.
 

The flue gas mass flow and combustion air mass flow of an open fire place depends on its opening.

m m
For the calculation use the following formula:
m = f ⋅ A , in kg/s (8)
mf F
mm= , in kg/s (8a)
where
f 2
mf is the mass flow factor of an open fire place, in kg/(s·m );
A 2;
F is the cross section of the opening of the open fire place, in m

For open fire places with an opening height less than or equal its width f = 0,139 kg/(s·m ).

For open fire places with an opening height greater than its width f = 0,167 kg/(s·m ).

The CO -content of the flue gas for open fire places may be taken as σ(CO ) = 1 %.

2 2

5.5.2.2 Flue gas mass flow and combustion air mass flow at the lowest permissible heat output

If the combustion appliance is designed to operate under modulating conditions an additional check shall

be conducted for the pressure and temperature requirement of the flue gas mass flow and combustion

air mass flow at the lowest possible and permissible heat output of the combustion appliance. If the

manufacturer does not provide flue gas data and combustion air mass data for the lowest heat output use

a mass flow of one third of the flue gas mass flow and combustion air mass flow at nominal heat output.

5.5.2.3 Flue gas mass flow and combustion air mass flow at the maximum draught or minimum

differential pressure of the combustion appliances

For the calculation of maximum draught or minimum positive pressure in a chimney the flue gas mass

flow and combustion air mass flow at maximum draught or minimum differential pressure of the

combustion appliance shall be obtained from the manufacturer of the combustion appliance if

appropriate.
5.5.2.4 Flue gas mass flow with secondary air

If secondary air is supplied by a draught regulator or draught diverter the air flow shall be calculated

according to 6.3 depending on the actual difference of the pressure in the room of installation of the

combustion appliance and the chimney or connecting flue pipe."
