Cara Kerja PLTU: Solusi Listrik Terbaru

>Hello Sohib EditorOnline, have you ever wondered how electricity is generated from coal? It’s a fascinating process that requires several mechanisms to work together to produce electricity. One of the most significant power plants that utilize coal to produce electricity is the PLTU (Pembangkit Listrik Tenaga Uap) or Coal-Fired Power Plant. In this article, we will discuss the working mechanism, components, and benefits of PLTU.

What is PLTU?

PLTU is a power plant that uses coal as its primary fuel to produce electricity. It’s a conventional thermal power plant that transforms the heat generated from burning coal into electricity.

The steam produced from the boiling water turns the turbine, which is connected to a generator that produces electricity. The main advantage of using coal as a fuel is its accessibility and low cost, making it an ideal source of electricity for many countries around the world.

How does PLTU work?

The PLTU working mechanism involves several steps that work together to produce electricity. The following section provides an overview of the working mechanism of PLTU.

Coal handling

The first step in the PLTU working mechanism is coal handling. The coal is transported to the power plant by a train or a truck and stored in a coal storage area. From there, the coal is transferred to the coal bunker using a conveyor belt.

After that, the coal is crushed into small pieces and mixed with air and ignited in the boiler. The burning coal produces heat that boils the water and produces steam.

Boiler

The boiler is the heart of the PLTU working mechanism. It burns the coal to produce heat that boils the water, and the steam produced drives the turbine. The boiler consists of several components, including the furnace, the burners, and the coal mills.

The furnace is where the coal is burned, and the burners supply the combustion air to the furnace. The coal mills grind the coal into a fine powder and deliver it to the furnace.

Turbine

The steam produced from the boiler turns the turbine, which is connected to the generator. The turbine consists of several stages that extract energy from the steam and convert it into mechanical energy.

Each stage of the turbine consists of a set of blades that rotate as the steam flows through them. The blades are arranged in a row, and as the steam passes through each row, it rotates the blade to extract energy from it.

Generator

The generator is the final component of the PLTU working mechanism that converts the mechanical energy from the turbine into electrical energy. The generator consists of a rotor and a stator. The rotor rotates inside the stator, which generates an electrical field.

The rotation of the rotor inside the stator produces electrical energy, and the electrical energy is transformed into high-voltage electricity that is sent to the transmission grid.

Components of PLTU

The PLTU consists of several components that work together to produce electricity. The following section provides an overview of the components of PLTU.

Coal handling system

The coal handling system is responsible for transporting the coal to the power plant, storing it, and delivering it to the boiler. The system consists of several components, including the coal bunker, the conveyor belt, and the crusher.

Boiler

The boiler is responsible for producing steam that drives the turbine. It’s composed of several components, including the furnace, the burners, and the coal mills.

Turbine

The turbine is responsible for extracting energy from the steam and converting it into mechanical energy. It consists of several stages that rotate as the steam flows through them.

Generator

The generator is responsible for converting the mechanical energy from the turbine into electrical energy. It consists of a rotor and a stator.

Cooling system

The cooling system is responsible for cooling the steam after it passes through the turbine. The system consists of several components, including the cooling tower and the condenser.

Benefits of PLTU

PLTU provides several benefits, including the following:

Low cost

Coal is a low-cost fuel, making PLTU an affordable source of electricity.

Accessibility

Coal is abundant and accessible in many countries worldwide, making it an ideal source of electricity for many countries.

Reliable
