The Cap-Djinet thermal power plant is a 1872-megawatt (MW) gas power plant located in Djinet in Algeria. The steam turbine is an important strategic machine in this plant. A malfunction of the turbine can generate a high maintenance and production cost due to the classical diagnosis method based on conditional maintenance.

Abstract. The steam turbine is one of the most critical equipment in the power generation system of thermal power plants, its daily operation condition and maintenance work will directly affect whether the power generation system can operate safely and stably. Therefore, it is necessary to strengthen the management of the steam

In thermal power stations, a heat engine like a steam turbine transforms the thermal energy from combustion into rotational energy used to power the generator. The main components of a coal-fired thermal power plant are the coal conveyor, pulverizer, boiler, steam turbine, condenser and cooling towers which work together to generate

Thermal power plants usually use boilers to heat water to produce steam, which in turn drives steam turbines to generate electricity. Maintenance of thermal

Thermal efficiency is defined as the ratio of heat equivalent mechanical energy available at the turbine to the heat energy available at the combustion of coal in the boiler. The thermal efficiency of the thermal power plants is 30% approx. Most of the heat energy (approx. 50%) is wasted in the condenser.

In order to avoid plant''s efficiency degradation, it is vital to develop an adequate maintenance plan, which can also improve the system''s reliability and availability. Several well-established

A thermal power plant is one kind of plant or system, which is used to produce electrical power by using thermal energy. Fig. 1 Thermal power plant. Coal is mainly used as fuel. Normally brown, bituminous, and peat coals are widely used. Water is used as secondary fuel which helps to transfer thermal energy from coal.

Moreover, proper monitoring and diagnosing systems should be installed in a thermal power plant''s turbine-generator system to detect any fault at an earlier stage. An imbalance rotor, misaligned shaft

Thermal power plants (TPPs) are critical to supplying energy to society, and ensuring their safe and efficient operation is a top priority. To minimize maintenance shutdowns and costs, modern TPPs have adopted advanced fault detection and diagnosis (FDD) techniques. These FDD approaches can be divided into three main categories:

The role of thermal power plants is expected to change from conventional base-load operation to peak-load operation depending on the power demand. During peak-load

This study deals with the shortage of electrical power generation in Port Sudan town in Sudan in 2005, and tries to suggest a solution to this problem. Information on the existing power plant and the grid in the

f those facilities, advanced preventive maintenance technology is important. For that reason, Hitachi has been grappling with nondestructive inspection, life

It also consist several major equipment and operations involve in its process. The purpose of hazard identification and risk assessment in thermal power plant is to identify physical, chemical, biological and environmental hazards in the plant, analyse the event sequences leading to those hazards and calculate the frequency and consequences of

As energy consumption will gradually increase into the future, efficient power generation of steam and electricity will be a key part of reliable systems usually used in industrial assets, including thermal power plants. This need puts the thermal power plant equipment in a deteriorating condition which worsens the system''s reliability.

A steam power plant works using a thermodynamic cycle describing the process by which energy is extracted from fuel and converted into electricity. In a typical thermal power plant, fuel (such as coal or natural gas) is burned in a boiler to produce heat. The heat is then used to generate high-pressure steam in a steam turbine, which

Drones can help improve power plant maintenance by providing safer inspections, expanding access to assets, increasing savings and ROI, and prolonging asset lifespans. 1. Improving Inspection Safety. Deploying an indoor drone into a confined space helps keep human inspectors out of potentially dangerous scenarios.

The gas turbine (GT), also known as the combustion turbine, is a rotary motor that removes energy from a hot gas flow generated in a stream of compressed air

Cooling towers are used to remove this excess heat by using evaporative cooling. In a thermal power plant, the hot water generated in the condenser is pumped to the cooling tower, where it is sprayed over a fill material. As the hot water is sprayed over the fill material, it comes into contact with the cool air entering the tower.

Maintenance is one of the most rapidly expanding activities in the industrial environment, since its application is no longer limited to simple, regular fixes. In the case of thermal power plants maintenance is essential, since they only operate when the National Electric System Operator wants them to complement the production from
