One point

this is my scientific expression;

it is only possible if and only if
Power output=Power needed to heat water to steam + Power damand of load

A boiler incorporates a
firebox or furnace in order to burn the fuel and generate heat . The generated heat is transferred to water to make steam , the process of
boiling. This produces saturated steam at a rate which can vary according to the pressure above the boiling water. The higher the furnace temperature, the faster the steam production..

jnfoage:
This is one of the questions I was asked in my present job interview.

The electrical power output of a steam turbine power plant can be used to heat up the boiler thereby generating steam for the plant without additional external energy source.

Technically justify or condemn this assertion.

One point will be awarded for this.

I will give additional one point for a scientific expression in support of your view.

change in u =q-w

The question just weak me but this is what I can offer

Next question in five minutes

sum of the each column is 15
1st column = 1+4+9+1 = 15
3rd column = 6+1+2+6 =15
4th column = 3+2+3+7 = 15


2nd = 15-(5+1+1) = 8
