In a certain diesel- electric power plant, diesel generator set has the following data:

  • Diesel fuel consumption-------- 109,495 kg
  • Electric power generated at switch board------ 518,000 kw
  • Direct excitation------3946 kw-hr
  • Number of generating hours ---- 595 hrs
  • Assume 90% generator efficiency and 80 % excitation efficiency

Determine the following :

1. Total BHP load of the engine

2. Pounds of fuel per kw-hr

3. Pounds of fuel per BHP-hr

4. With nominal out put rating of 1520 HP, at what load percent engine has run its rated capacıty.

5. Circulating water enter's the diesel engine at 80 F and leaves at 110 F. Assuming that this operation, 0.15 gal per min. of cooling water per BHP is circulated, what percent of heat energy is taken by the circulating water if fuel with HV of 19,000 Btu/Ib is used.

6. The brake thermal efficiency
