What is the cooling system of a diesel generator?

The Cooling system of the diesel generator compromises of the following main components: Water Pump is a gear-driven pump and runs to circulate the coolant through the engine. Radiator is an air-cooled heat exchanger that comes with a provision of air inlet and air outlet.

How much airflow should a gen set have?

The ventilation system should sufficiently move air to control temperature in all areas of the engine room. The following equations provide the proper airflow (cfm or m3/s velocity for a given gen set installation, assuming 100 F (38C) ambient temperature: Airflow (cfm or m3/s should increase 10 percent for every 2,500 feet (760m) above sea level.

How does engine temperature affect the life of a generator?

During the combustion process, the temperature and pressure within the engine drastically increases. The temperature is required to be cooled down otherwise this can cause wear and tear within the engine and thus can deteriorate the life of the generator.

How does compressor inlet temperature affect turbine output and heat rate?

The ambient effect curve (see Figure 9) clearly shows that turbine output and heat rate are improved as compressor inlet temperature decreases. Lowering the compressor inlet tem-perature can be accomplished by installing an evaporative cooler or inlet chiller in the inlet ducting downstream of the inlet filters.

How do you remove radiant heat from a gen set?

The most efficient method of removing this heat is with a system that pulls air past switchgear, then over the engine, from back to front. If air curtains are used, the airflow should gather this radiant heat just above the gen set, which offers greater efficiency and less exposure to high air velocities in other areas of the gen set room.
