There are many means of improving the energy efficiency of a power plant – from
the replacement of a single component to complete modernisation or operation
and maintenance solutions. There are also many aspects that affect a plant’s
energy efficiency, and these need to be examined before choosing the suitable
improvement solution. Some key factors are fuel consumption, fuel price, price
of electricity in the operating area and the maximum output of the plant.
The first thing to look at is the engine – specifically the fuel system. What
fuel does the plant use – oil or gas? What quality is the fuel, and does it
correspond to the original parameters used in the construction phase of the
plant? The condition of the engine and the fuel injection system is also very
important – have they been properly maintained or left to gather dirt and crust?
Charge air and removal of exhaust gas, as well as the condition of the boiler play a role too. The cooling system, specifically the quality of the cooling water,
can also impact energy efficiency. Has it been purified to a sufficient extent? The next aspect is the operation of the plant. Is it operated according to the original parameters, or has the plant operator changed the operating profile to match changed needs? Does the number of engines match the customer need, and are they being run at an optimal load or is the load too high or low? Regular maintenance is naturally an important factor, as well. In some cases, the plant operator already knows where the challenges are, while in others, there are more open questions. In the latter situation, a site audit conducted by energy efficiency experts helps identify equipment and processes with improvement potential. In all cases, technical schematics of the plant and its designed operating parameters, as well as all available operational data are examined to ensure that there is sufficient information for selecting the best improvement solution.
