Gas Flashcards
1
Q
Wobbe Index
A
- value for the interchangeability of gases with
regard to heat load - gas can be changed without changing burner nozzle
2
Q
Upper Wobbe Index
A
Upper calorific value of the fuel gas [J/m³ or kWh/m³] = Hs / Wurzel(Relative density, d = p (fuel gas)/p(air))
3
Q
Lower Wobbe Index
A
Lower calorific value of the fuel gas [J/m³ or kWh/m³] = Hi / Wurzel(Relative density, d = p (fuel gas)/p(air))
4
Q
Calorific value?
A
lower and upper heating value
5
Q
Ideal gas formula
A
p*V = m * Rs * T = n * R * T
6
Q
Specific gas constant
A
Rs = R/M
7
Q
Dichte
A
m/V
8
Q
What is the universal gas constant?
A
R = 8,314
9
Q
How do you calculate the specific gas constant?
A
Rs = R/M
10
Q
Molar mass
A
M = m/n
11
Q
Exergy share
A
Q * nc (= Carnot efficiency)
