[6] [7]. GA is tried in some of the thermal power plant modelling and estimation problems [8] [10]. Coal mill model development is based on measurable variables from physical analysis and real time plant data. Since a coal mill is a multiinputmultioutput nonlinear system with a
Coal Pulverising in Boilers Bright Hub Engineering 1 Jun 2011 The fineness of the coal is also important in overall mill efficiency and in in industry: the slow speed mills like ball tube mills, the medium speed mills like50 HGI normally is taken for calculating the base capacity of the mill.
Nov 17, 2012#0183;#32; pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boiler burner
Land available for 4,000 MW (Nominal) coal based power plant is about 1242 Ha, which includes main plant, balance of plant, ash disposal area, green belt, roads, MGR and drains etc. This site is situated in coastal area at Tundawand village.
Dec 13, 2011#0183;#32;A higher Hardgrove index indicates the coal is easier to grind. 50 HGI normally is taken for calculating the base capacity of the mill. When coal with HGI higher than 50 is fed to the pulverizer, the output will be higher than base capacity, and below 50 HGI, the output will be lower. The total moisture in coal has a high effect on mill output.

Exercise 18 Calculate Coal Use for Power Plant. 1000 MW = 1,000,000,000 J . g . kJ = ___ g sec. 30 kJ 1000 J sec. ____ g/sec. = __?__ g/sec of coal (39,215).
After considering the conversion efficiency in a power plant we require an heat input of (3600 / % ) 10765 kJ/ kw hr. Coal Quantity. Since coal has a heat value of 20,000 kJ/kg, for producing one we require (10765 / 20000) kg of coal. This translates to ( x 100 x 1,000) 53800 kg/hr ( T/hr) of coal for an output of 100 MW.
The present analysis was conducted on a coal based thermal power plant of 500 MW capacity comprising of 2X250 MW units and the following parameters were recorded: (a) Plant Availability Factor (PAF) To calculate PAF of a power plant the amount of time that it

150 MW requires coal consumption: 10765/(10500 kJ/kg to 25000 kJ/kg)x150. This is the theoretical value of the estimation, and the actual power plant coal consumption is related to the quality of coal and the efficiency of boilers.
