GASDRUCK

In den nebenstehenden Tabellen werden die
Mindestströmungsverluste entlang der Gaszu-
leitung in Abhängigkeit der Brennerleistung auf
der 2. Stufe angezeigt.

Spalte 1
Strömungsverlust Flammkopf.
Gasdruck an der Entnahmestelle 1)(B) gemes-
sen, bei:
• Brennkammer auf 0 mbar;
• Brennerbetrieb auf der 2. Stufe;
• Gemäß Diagramm (C)S. 16 eingestellter Gas-

scheibe 2)(B)S. 16.

Spalte 2
Strömungsverlust Gasdrossel 2)(B) bei maxima-
ler Öffnung: 90°.

Spalte 3
Strömungsverlust Armaturen 3)(B) bestehend
aus: Regelventil VR, Sicherheitsventil VS (beide
bei maximaler Öffnung), Druckregler R, Filter F.

Die Tabellenwerte beziehen sich auf:
Erdgas G20 - Hu 10 kWh/Nm

(8,6 Mcal/Nm

3

)

Bei:
Erdgas G 25 - Hu 8,6 kWh/Nm

(7,4 Mcal/Nm

3

) die 

Tabellenwerte:
- Spalte 1: mit 1,3;
- Spalte 2-3: mit 1,49;
multiplizieren.

Zur Ermittlung  der ungefähren Brennerleistung
im Betrieb auf der Höchstleistung des Brenners:
- Vom Gasdruck an der Entnahmestelle 1)(B)

den Druck in der Brennkammer abziehen.

- In der Tabelle des betreffenden Brenners,

unter Spalte 1, den der Subtraktion nächsten
Wert ablesen.

- Die entsprechende Leistung links ablesen.

Beispiel - RS 68/M BLU:
• Betrieb auf 2. Stufe
• Erdgas G20 Hu 10 kWh/Nm

3

• Gemäß Diagramm (C)S.16 eingestellte 

Gasscheibe 2)(B)S.16.

• Gasdruck an der Entnahmestelle 1)(B) =11,6 mbar
• Brennkammerdruck

=3,0 mbar

11,6 - 3

=8,6 mbar

Dem Druck von 8,6  mbar, Spalte 1, entspricht
in der Tabelle RS 68/M BLU eine Leistung auf
der 2. Stufe von 700 kW.
Dieser Wert dient als erste Näherung; der tat-
sächliche Durchsatz wird am Zähler abgelesen.

Zur Ermittlung des für den an der Entnahme-
stelle 1)(B) erforderlichen Gasdruckes, nach-
dem die Brennerleistung auf 2. Stufe festgelegt
wurde:
- In der Tabelle des betreffenden Brenners die

dem gewünschten Wert nächste Leistungsan-
gabe ablesen.

- Rechts, unter der Spalte 1, den Druck an der 

Entnahmestelle 1)(B) ablesen.

- Diesen Wert mit dem angenommenen Druck

in der Brennkammer addieren.

Beispiel - RS 68/M BLU:
• Gewünschte Leistung auf 2. Stufe: 700 kW
• Erdgas G20 Hu 10 kWh/Nm

3

• Gemäß Diagramm (C)S.16 die Gasscheibe

2)(B)S.16 einstellen.

• Gasdruck bei 700 kW Leistung, aus Tabelle

RS 68/M BLU, Spalte 1

=8,6 mbar

• Brennkammerdruck

=3,0 mbar

8,6 + 3

=11,6 mbar

Erforderlicher Druck an der Entnahmestelle
1)(B).

GAS PRESSURE

The adjacent tables show minimum pressure
losses along the gas supply line depending on
the burner output in 2nd stage operation.

Column 1
Pressure loss at combustion head.
Gas pressure measured at test point 1)(B), with:
• Combustion chamber at 0 mbar;
• Burner operating in 2nd stage;
• Gas ring 2)(B)p.16 adjusted as indicated in

diagram (C)p. 16.

Column 2
Pressure loss at gas butterfly valve 2)(B) with
maximum opening: 90°.

Column 3
Pressure loss of gas train 3)(B) includes: adjust-
ment valve VR, safety valve VS (both fully open),
pressure governor R, filter F.

The values shown in the various tables refer to:
natural gas G 20 PCI 10 kWh/Nm

(8,6 Mcal/Nm

3

)

With:
natural gas G 25 PCI 8,6 kWh/Nm

(7,4 Mcal/Nm

3

)

multiply tabulated values:
- column 1: by 1.3;
- column 2-3: by 1.49.

Calculate the approximate maximum output of
the burner thus:
- subtract the combustion chamber pressure

from the gas pressure measured at test point
1)(B).

- Find the nearest pressure value to your result

in column 1 of the table for the burner in ques-
tion.

- Read off the corresponding output on the left.

Example - RS 68/M BLU:
• 2nd stage operation
• Natural gas G 20 PCI 10 kWh/Nm

3

• Gas ring 2)(B)p. 16 adjusted as indicated in

diagram (C)p. 16.

• Gas pressure at test point 1)(B)

=11,6 mbar

• Pressure in combustion chamber

=3,0 mbar

11,6 - 3

=8,6 mbar

A 2nd stage output of 700 kW shown in Table
RS 68/M BLU corresponds to 8,6 mbar pres-
sure, column 1.
This value serves as a rough guide, the effective
delivery must be measured at the gas meter.

To calculate the required gas pressure at test
point 1)(B), set the output required from the
burner in 2nd stage operation:
- find the nearest output value in the table for

the burner in question.

- Read off the pressure at test point 1)(B) on

the right in column 1.

- Add this value to the estimated pressure in

the combustion chamber.

Example - RS 68/M BLU:
• Required burner output in 2nd stage opera-

tion: 700 kW

• Natural gas G 20 PCI 10 kWh/Nm

3

• Gas ring 2)(B)p. 16 adjusted as indicated in

diagram (C)p. 16.

• Gas pressure at burner output of 700 kW, taken

from table RS 68/M BLU, column 1 = 8,6 mbar

• Pressure in combustion chamber

= 3,0 mbar

8,6 + 3

=11,6 mbar

pressure required at test point 1)(B).

PRESSION DU GAZ

Les tableaux ci-contre indiquent les pertes de
charge minimales sur la ligne d'alimentation en
gaz en fonction de la puissance du brûleur en
2ème allure.

Colonne 1
Perte de charge tête de combustion.
Pression du gaz mesurée à la prise 1)(B), avec:
• Chambre de combustion à 0 mbar;
• Brûleur fonctionnant en 2ème allure;
• Bague du gaz 2)(B)p.16 réglée selon le dia-

gramme (C)p. 16.

Colonne 2
Perte de charge vanne papillon gaz 2)(B) avec
ouverture maximum: 90°.

Colonne 3
Perte de charge de la rampe gaz 3)(B) compre-
nant: vanne de régulation VR, vanne de sécurité
VS (ayant chacune une ouverture maximum),
régulateur de pression R, filtre F.

Les valeurs reportées sur les tableaux se réfè-
rent à:
gaz naturel G 20 PCI 10 kWh/Nm

(8,6 Mcal/Nm

3

)

Avec:
gaz naturel G 25 PCI 8,6 kWh/Nm

(7,4 Mcal/Nm

3

)

multiplier les valeurs des tableaux:
- colonne 1: par 1,3;
- colonne 2-3: par 1,49.

Pour connaître la puissance maximum approxi-
mative à laquelle le brûleur fonctionne:
- Soustraire la pression dans la chambre de

combustion de la pression du gaz à la prise
1)(B).

- Repérer la valeur la plus proche du résultat

obtenu sur le tableau relatif au brûleur consi-
déré, colonne 1.

- Lire la puissance correspondante sur la gau-

che.

Exemple - RS 68/M BLU:
• Fonctionnement en 2ème allure
• Gaz naturel G 20 PCI 10 kWh/Nm

3

• Bague du gaz 2)(B)p.16 réglée selon le dia-

gramme (C)p. 16.

• Pression du gaz à la prise 1)(B)

=11,6 mbar

• Pression en chambre de combustion =3,0 mbar

11,6 - 3

=8,6 mbar

Sur le tableau RS 68/M BLU la pression de 8,6
mbar, colonne 1, correspond une puissance en
2ème allure 700 kW.
Cette valeur sert de première approximation; le
débit effectif est mesuré sur le compteur.

Par contre, pour connaître la pression du gaz
nécessaire à la prise 1)(B), après avoir fixé la
puissance de fonctionnement du brûleur en
2ème allure:
- Repérer la puissance la plus proche à la

valeur voulue dans le tableau relatif au brû-
leur concerné.

- Lire la pression à la prise 1)(B) sur la droite,

colonne 1.

- Ajouter à cette valeur la pression estimée

dans la chambre de combustion.

Exemple - RS 68/M BLU:
• Puissance désirée en 2ème allure: 700 kW
• Gaz naturel G 20 PCI 10 kWh/Nm

3

• Bague du gaz 2)(B)p. 16 réglée selon le dia-

gramme (C)p. 16.

• Pression du gaz à la puissance de 700 kW, sur

le tableau RS 68/M BLU, colonne 1 =8,6 mbar

• Pression dans la chambre de comb.=3,0 mbar

8,6 + 3

=11,6 mbar

pression nécessaire à la prise 1)(B).
