Best Answer

Power cogeneration is a method of energy conservation. Specifically, it refers to the process of increasing the efficiency of our energy delivery processes by utilizing wasted heat energy. For example, hot water is an unused product of electric power plants (water is used for cooling purposes). In certain countries, like the US, this hot water is dumped into lakes or rivers. Instead, that hot water can be redirected to heat homes, like in most countries in Europe. This is doubly effective because electricity is used to heat most homes in America, and if we take advantage of waste heated water, we can cut down on our electricity consumption.

What does cogeneration mean definition?

The definition of the word 'cogeneration' means that electricity is produced from either an engine or power station and that the electricity is turned into useful heat.

What is cogeneration?

Cogeneration is the simultaneous production of electricity and useful heat from a single fuel source, typically through the use of a power plant or industrial facility. This process increases energy efficiency by capturing waste heat that would otherwise be released into the environment. Cogeneration systems are also known as combined heat and power (CHP) systems.

Is it necessary to improve Power Factor in captive generating units?

Potentially. This would depend on the size of the cogeneration, and on the location in the electrical grid. Generally, the larger the cogeneration, the more requirements will be placed on it to act like a typical power plant (specific MVAR/MW output within specified power factor ranges, must stay online for faults, etc.).

What is the production of two useful forms of energy from the same fuel source called?

Cogeneration, or combined heat and power (CHP), is the production of electricity and useful thermal energy (such as heat or steam) from the same fuel source in a single process. This process increases the overall efficiency of energy production compared to separate generation methods.

What is the difference between combined cycle and cogeneration?

In Cogeneration Plant : The generated steam in boiler is used for both power generation & process heating, thereby reducing the condenstion losses compared to thermal power plant. In combined cycle first is gas turbine , rather than wasting the flue gas from gas turbine, we are sending it into boiler and again generating steam for running steam turbine. Both the ways we are increasing the thermal efficiency of the plant
