$1.$ Prepare an $8-$item heat balance in $k\frac{J}{k}g$ of fuel and in $\%$ of HHV bases. Tabulate

results in $k\frac{J}{k}g,k\frac{J}{h}r$ and $\%$ bases.

$2.$ What is the overall steam generator efficiency? Analyze this item. Can This be

improved? How? Support your answer with computations if possible.

$3.$ Analyze the losses too, can these be reduced? How? Support your answer with

computations if possible.
