A Study on Operation of 210 Mw Steam Turbine Power Plant at Ghorashal Power Station

Abstract

Electric power is produced at the power stations by using different type of fuel, which is located at favorable places in a company. The cost of fuel gas is low then the other fuel. For that purpose, gas based steam power plant contributes greatly to supply vast power in the possible time. Prime mover can be run by different types of fuel like gas, coal, diesel etc. Ghorashal Power Plant is gas based Steam Power Plant. Gas based steam power plant depends on proper fuel treatment system, lubricating oil system, cooling system, electrical generation and safety system, fresh water supply system, heat recovery system etc. Again, lubricating oil is purified by lubricating oil separator that protects engine from friction and damage. Boiler produces steam from the gas and contributes into necessary locations for various purposes. Cooled water is supplied to the various parts of the engine by the help of cooling tower system to prevent damage due to high temperature. The generation of large electric power depends upon the proper operation and immediate maintenance work of the turbine, boiler and other electrical devices. All system are interrelated deeply and played important roles in power generation. So, if any system is fault whatever it is mechanical or electrical system or others, influence significantly on overall power plant. The proper knowledge of different systems can save the plant from possible hazards and helps genuinely to the proper electric power generation. The power generated from the power plant will be supplied to Bangladesh Power Development Board (BPDB) which is the main customer of the company.
