Increasing the production capacity of power plants by reducing the inlet temperature to turbines

According to the economic correspondent of Fars News Agency, focusing on knowledge-based industries can change the playing field of the country’s economy and lead to the opening of many hypothetical deadlocks of the country’s economy.

Accordingly, one of the most important sectors that need a strong entry of knowledge-based industries is the country’s energy sector, where due to incorrect policy in recent years has caused widespread problems and in many energy carriers in Iran despite the capacity Significant production has become an importer of energy.

In this regard, moving towards improving the operational capacity of power plants as an important part of the country’s energy puzzle for the optimal use of fossil fuels can be a fundamental step in using knowledge-based industries to improve the country’s energy conditions.

At This time“Ali Akbar Mehrabian, Minister of Energy, on the sidelines of the meeting of the Energy Commission of the Parliament regarding the government’s plan to improve the operational capacity of the country’s electricity generation units, says:”“We plan to add more than 1,000 megawatts to the capacity of the plants, without adding fuel and without massive investment, using only knowledge-based methods.”

* Details of the program to upgrade the power plant units by reducing the inlet temperature to the turbine

.According to the plan of the Ministry of Energy, in order to upgrade the thermal power generation units by the summer of this year, the upgrade of 1113 MW of these power plants in the form of 286 units is on the agenda.

Accordingly, one of the most important programs to increase the capacity of current power plants without the need to increase fuel and at a cost of less than 10% of the cost of construction of the plant, to install cooling turbine inlet air cooling system relying on two methods media And the wet density is restored along with the modification of the cooling system of the heater units.

In this regard, two sets of knowledge base along with the thermal power generation company, using technological methods, have provided the possibility of reducing the inlet temperature of the turbine, and thus increase the efficiency of the country’s power plants. FarahThey do.

According to the details provided by the experts in the electricity industry, reducing the temperature difference between the environment and the turbine will reduce the efficiency of power plants, in this regard by increasing the air temperature and keeping the turbine temperature constant in the hot season that requires more electricity. From other times of the year, we see a decrease in the efficiency of power plants.

In this regard, the use of these knowledge-based methods will help to improve the operational efficiency of power plants by reducing the inlet air temperature to the turbine.

The use of this system is on the agenda of 33 power plants in the country and can provide a maximum upgrade of 700 MW of power plants in the country.

* Special result of using knowledge-based methods in increasing the capacity of power plants

According to the latest information received from Iran Power Grid Management Company, considering that the air temperature has not risen in some parts of the country at the beginning of June and it is still not possible to test cooling systems, 321 MW of 700 MW capacity has been upgraded to installation method. Inlet air temperature reduction systems are included in the turbine and the rest will be added to the capacity of the country’s electricity network by increasing the air temperature in different regions of the country.

Examining the production diagrams of two power plants in the center of the country shows how much the use of the cooling system in each unit will help generate electricity.

* Increase power generation capacity without the need for fuel and at a very low cost

According to Fars, the first benefit of the operational capacity upgrade program using the installation of cooling systems is the significant economic benefit of this project.

In a situation where the construction of an 1855 MW power plant with the highest technology requires at least 650 million Euros, equivalent to 19.5 thousand billion Tomans, the economic estimate details of the power plant upgrade project are much less than the amount stated for the construction of a new power plant and up to 10% The cost of building a power plant is equivalent to generating electricity.

In other words, by spending much less than building a power plant, we can see a similar performance from the program to improve the operational capacity of the country’s power plants.

On the other hand, power upgrades are done without the need for any fuel, in other words, despite the limited supply of fossil fuels to the country’s power plants, these capacity building programs have a special and strategic role because in fact by reducing fuel consumption, electricity generation And with nine does not add new fuel capacity.
