Feedwater heaters are used preheat the water in order to decrease the heating time in the boiler and increase the plant’s overall efficiency. In large power plants, the water that exits the condenser is sent through a series of feedwater heaters. The tanks are heated by steam from the turbine.
Our field-erected boilers, designed to be fired by the wellons cell furnace system. Provide the greater steam flow, higher pressure and the higher temperatures needed for power plants. Wellons' approach to lower emission levels starts with preventative measures taken at the furnace where formation of gaseous pollutants begins.
Combustion turbine or reciprocating engine CHP systems burn fuel (natural gas, oil, or biogas) to turn generators to produce electricity and use heat recovery devices to capture the heat from the turbine or engine. This heat is converted into useful thermal energy, usually in the form of steam or hot water. Steam Boiler with Steam Turbine
p Efficiency of power generation Indices: CHPP Combined heat and power plant HP Heat or steam boiler plant Formula (2) can be used to investigate whether it is more economical to generate power in the industrial operator’s own plant or to meet the full power demand with energy purchased from the utility (ie, whether the plant should produce steam
Combined heat and power (CHP), also known as cogeneration, is: The concurrent production of electricity or mechanical power and useful thermal energy (heating and/or cooling) from a single source of energy. A type of distributed generation, which, unlike central station generation, is located at or near the point of consumption.
Boiler in a power plant has two functions. The Combustion system converts energy in coal to Heat. Water and steam system converts the heat to steam at high pressures and temperatures. This series explains the working of the boiler in modern power plant.
