The boiler, furnace and grate efficiency of a steam generator is 72%. Coal with a moisture content of 8% is burned at the rate of 454 kg per hour. The heating value per kg of dry coal is 26,752 KJ. Steam is generated at 3.2 MPa and a temperature of 230^oC. Feed-water temperature is 93^oC. Determine:

 a) the kg of steam generated per hour

 b) the Developed Boiler Hp.

 c) the Equivalent evaporation in kg per kg of coal as fired

 d) the cost to evaporate 500 kg of steam if coal costs P 150 per Metric Ton
