A fuel used in a boiler contains 86.1% carbon, 11% hydrogen, 2.6% oxygen and 1% sulfur. There are 40% excess air supplies to the furnace and the fuel rate is 400 kg/HR. Calculate the mass of air and the heat energy transfer to the air hour if enters the air heater at 18 Deg c and leaves at 130 Deg c

While discussing the reaction by a refrigerant to heat:

MGT range extender using hydrogen fuel thermal analysis and research gap.

In a gas turbine plant, 1000 ° C from the combustion chamber and 1 MPa gases entering with pressure, the turbine with an isentropic efficiency of 90% expands up to pressure. Turbine well it is not insulated and the temperature of 25 ° C and 100 from the turbine during expansion It was determined that there is a significant heat loss to the environment at kPa pressure. has been. Characteristics of air for combustion products and the following using admissions; (a) The actual and reversible specific power output of the turbine, (b) Specific exergy of the air in the inlet and outlet conditions, (c) Second law efficiency, (d) Heat transfer between the turbine and its surroundings and the work produced by the turbine Exergy transfer amounts with, (e) Calculate the irreversibility of the whole process. Assumptions: (i) The power generated by the heat transfer from the turbine to its surroundings is 18% (ii) Consider variable specific heat
