Question

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

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

Determine the following :

1. Total BHP load of the engine

2. Pounds of fuol per kw-hr

3. Pounds of fuel per BHP-hr

4. With nominal out put rating of 1520 HP, at what load percent engine 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 cool ing water per BHP is circulated, what percent of heat energy if fuel with HV of 19,000 Btu/Ib is used.

6. The brake thermal efficiency
