(Solved): 2.1 Calculate the evaporation capacity in k(g)/(s) of the boiler for condition 1 without superheater ...
2.1 Calculate the evaporation capacity in k(g)/(s) of the boiler for condition 1 without superheater.
2.2 Calculate the fuel mass flow m_(Fuel )^(?) and the supplied heat flow H_(Fuel )^(?).
Assumption: Ambient temperature = gas temperature.
2.3 Calculate the exhaust gas mass flow m_(exhaust )^(?) towards the ambient conditions and the heat
flow Q_(exhaust )^(?) discharged by the exhaust gas. The estimated heat capacity of the exhaust gas
is c_(p), exhaust =1.05k(J)/(k)g*K.
2.4 Determine the so-called combustion efficiency: \eta _(f)=1-(Q_(exhaust )^(?))/(Q_(fuel )^(?)).
2.5 Calculate the heat flow Q_(cw)^(?) dissipated through the cooling water. Calculate the heat flow for
the generator side and the turbine side separately.
2.6 What is the power output of the turbine Pturbine ? Calculate for condition 1 and 2. Determine
the increase of power by superheated steam in %.
Hint for the proper equation: rotating device, torque and speed are known values.
2.7 Make an energy balance of the complete power plant. Is the sum of all energies supplied
equal to the sum of the power carried out? Discuss the results.
