Activated carbon filters are very commonly used in water treatment plants to remove contaminants. They have a bed of Carbon where containments are attached by a phenomenon called adsorption. The purpose of an activated carbon filter is to remove free chlorine, an oxidizing agent that will damage most resins and reverse osmosis membranes…
Filtration is a technique in which solids or impurities are separated from the liquid by passing the liquid through filter media. The filter media has pores. These pores will allow water to pass while retaining the solid particles. The liquid that passes through filter media is called filtrate. The materials that are retained…
Water clarification is very important in water treatment plant dpening the water source you have Clarification is the method used to remove suspended matter from surface water and industrial wastewater. In essence, it makes “turbid” water “clear,” as shown below in Figure Clarification removes suspended matter from water. Surface waters require clarification because…
Water treatment is necessary for removing the impurities that are contained in water as found in nature. The impurities and salts that are present in the water will form scaling and fouling on the respective equipment and will damage the performance of that equipment. If scaling and fouling will happen to the boiler heat…
Lubrication is a technique in which lubricant is use to reduce friction between rotating parts such as Bearing and shaft. The lubrication system produces cooled, filtered oil for the bearing of the Gas Turbine and the Generator. The lubricating provisions for the turbine, generator, torque converter and accessory gear box are incorporated in…
A Cooling tower is the type of heat exchanger in which water and air are brought into contact naturally or forcefully depending upon the type of cooling tower you are using. The warm water comes in contact with cooled air and this heat is transferred to the air which flows outside of the…
The heat recovery steam generator (HRSG) provides the thermodynamic link between the gas turbines and steam turbines in a combined-cycle power plant. Its basic function is to recover the heat from gas turbine exhaust. This recovered heat will be utilized to heat water to convert the water into steam. This steam will be…
The control oil system of steam turbine is completely separated from the lubricating oil system of steam turbine. A dual pump system is adopted. One is usually operating and the other is stand-by. The type of control oil pump is the variable displacement piston type, driven by AC motor. They are installed beside…
The purpose of the lube oil system is to : Note: The continuous oil supply for each steam turbine and generator bearings must be kept. (Main Oil Pump (MOP) shall be operated.) If it stops, the bearings will be fatally damaged. the technical data of our steam turbine is already explained in this…
The steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft which is connected to a generator. Steam passes from the first to the last stage its pressure drops and the specific volume increases as a result it does…
