Energy Efficiency in Belawan PLTG: Designing HRSG to Take Advantage of Gas Turbine Exhaust Gas

Introduction

The world is facing an increasing energy demand due to rapid technological advancements. To meet this demand, it is essential to explore ways to utilize existing resources more efficiently. One solution is to design machines that can maximize energy use. In this context, research on the Heat Recovery Steam Generator (HRSG) that utilizes gas turbine exhaust gas in PLTG PT. PLN (Persero) Generation and Distribution of North Sumatra, specifically in the Belawan sector, is of great interest.

What is HRSG?

HRSG is a type of steam or boiler that utilizes the remaining heat energy from the gas turbine exhaust gas. This heat is used to heat water and convert it into steam, which is then used to move the steam turbine. HRSG is generally not equipped with burners and does not consume fuel, so the radiation heat transfer process does not occur. This makes HRSG an attractive option for increasing energy efficiency in power plants.

Theoretical Background

HRSG works by utilizing the heat energy from the gas turbine exhaust gas to produce steam. This steam is then used to move the steam turbine, which generates electricity. The process can be broken down into several stages:

Heat Recovery: The heat energy from the gas turbine exhaust gas is recovered and used to heat water.
Steam Generation: The heated water is converted into steam, which is then used to move the steam turbine.
Electricity Generation: The steam turbine generates electricity, which is then fed into the power grid.

Advantages of Utilizing HRSG in Belawan PLTG

Utilizing HRSG in Belawan PLTG has several advantages:

*** Increasing Efficiency: **By utilizing the remaining heat from gas turbine exhaust gas, HRSG can increase the overall efficiency of the PLTG. This is because the energy produced can be used to produce steam that moves steam turbines, reducing energy waste. *** Fuel Savings: **Because HRSG does not require a burner, the use of fuel to produce steam can be reduced. This has a positive impact on saving the operational costs of PLTG. *** Environmentally Friendly: **Reduction of fuel consumption means that greenhouse gas emissions are also reduced. Utilization of HRSG is an environmentally friendly step and supports efforts to reduce the negative impact on climate change.

Deeper Analysis

To determine the theoretical performance of HRSG and determine the necessary components, a deeper analysis is required. This involves understanding the performance of HRSG, including:

Heat Transfer: Understanding the heat transfer process between the gas turbine exhaust gas and the water.
Steam Generation: Understanding the process of converting heated water into steam.
Steam Turbine: Understanding the process of generating electricity using the steam turbine.

Conclusion

Research on the design of HRSG that utilizes gas turbine gas in the Belawan PLTG has a great potential to increase energy efficiency and environmentally friendly. By understanding HRSG performance theoretically and determining the right components, we can maximize the use of residual heat energy. This opens opportunities to achieve higher energy efficiency targets and support sustainable energy development.

Future Work

Future work on HRSG design and implementation in Belawan PLTG should focus on:

Experimental Validation: Conducting experiments to validate the theoretical performance of HRSG.
