Calculate the fuel flow rate (Ton / hour) for 18.5 MWe power plant with fuel heating value of 25.7 MJ/kg.

To calculate the fuel flow rate, we need to convert the power plant capacity from MWe to MJ/hr first.

1. Convert MWe to MJ/hr We know that 1 MWe = 3.6 GJ/hr, so 18.5 MWe = 18.5 * 3.6 GJ/hr = 66.6 GJ/hr.

2. Convert GJ/hr to MJ/hr We know that 1 GJ = 1000 MJ, so 66.6 GJ/hr = 66.6 * 1000 MJ/hr = 66600 MJ/hr.

3. Calculate the fuel flow rate The fuel flow rate is calculated by dividing the total energy requirement by the energy content of the fuel. So, the fuel flow rate = 66600 MJ/hr / 25.7 MJ/kg = 2591.05 kg/hr.

4. Convert kg/hr to Ton/hr We know that 1 kg = 0.001 Ton, so 2591.05 kg/hr = 2591.05 * 0.001 Ton/hr = 2.591 Ton/hr.

So, the fuel flow rate for an 18.5 MWe power plant with a fuel heating value of 25.7 MJ/kg is approximately 2.591 Ton/hr.
