Price : Get Quote Operating Capacity : Up to 150 t/h,Up to 100 t/h,Up to 50 t/h Belt width : 1200 mm,1000 mm,800 mm Gravimetric Coal Feeder manufactured by Demech is essentially a belt conveyor which measures the amount of coal, in terms of weight, being conveyed fed to the pulveriser The feed rate is computed from load cell signal and belt speed signal collected from the load ...
Mar 17, 2015· Using the Steam Property Calculator, properties are determined using Steam Pressure and Quality = 0 (Saturated Liquid). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Blowdown Energy Flow = Specific Enthalpy * Mass Flow; Step 4: Determine Boiler Energy.
The basic function of the power plant is to convert energy in coal to electricity. Therefore, the first thing we should know is how much energy there is in coal. Energy content of coal is given in terms of KiloJoules (kJ) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV) of coal. This value can vary ...
Aug 14, 2016· Usually, in a thermal power plant it is required or most compulsory requirement to measure the flow of coal which is to be sent into the boiler (Sometimes through pulveriser mill in PC Fired Boiler). For this we used to weight the coal that is fed...
Thermal Power Plant Working | INDIAN POWER SECTOR. Raw coal from the raw coal bunker is supplied to the Coal Mills by a Raw Coal Feeder The Coal Mills or pulverizer pulverizes the coal to 200 mesh size The powdered coal from the coal mills is carried to the boiler in coal pipes by high pressure hot air The pulverized coal air mixture is burnt in the boiler in the combustion zone

Power Generation 1 MWh = 3600 MJ 1 MW = 1 MJ/s 1 MW (thermal power) [MWth] = approx 1000 kg steam/hour 1 MW (electrical power) [MWe] = approx MW(thermal power) 3 A 600 MWe coal-fired power station operating at 38% efficiency and 75% overall availability will consume approximately: – Bituminous coal (CV 6000 kcal/kg NAR*): 1.5 Mt/year
Unlike the mechanical gravimetric feeder which acts to vary the height of coal in response to density changes to maintain a pre-established weight of coal on the weigh span, the electronic weighing feeder measures the actual density of coal and varies the belt speed to match actual with demanded combustion control delivery requirements.
Jan 08, 2016· Train: It is one of the major modes of transportation for supplying coal to various plant locations. All the thermal power plants are having the facility for receiving coal by Trains. It is very cost effective as compared to the Trucks and one rack of wagons can carry coal up to 4000 Tons.
The first Stock gravimetric feeder operated from 1957 to 1992, to be replaced by current gravimetric microprocessor-controlled design. This feeder was donated to Stock Equipment, refitted, and refurbished for public display in the engineering plant.
The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.
