role of ash for calculating ncv of coal in philippines

Coal Composition, Why is coal composition and quality important to gas analysis? To begin with, the chemical composition of coal is analyzed by proximate and ultimate analyses (ASTM, 1993)Proximate analysis determines by using set procedures regarding moisture, volatile matter, fixed carbon, and ash content (Figure 521)Proximate analysis is reported by percent on as-received, moisture-free, and moist- and ,Calorific Value or Heating Value of the Fuel & Moisture ,, Coal is the primary fuel for producing Electricity Some of the characteristics of coal have profound influence on the day to day working and economics of the power plant This article discusses Calorific Value and Moisture Calorific value is the most important parameter that determines the economics of the power plant operation It indicates the amount of heat that is released when the coal ,Ash Analysis | Mining | SGS, The data resulting from ash elemental analysis, ash fusion tests and other coal ash analyses performed in our state-of-the-art laboratories around the world will help you to make important decisions that affect the efficiency of your plant operation, and help you to control your coal quality challengObjective Type, a) ash content b) water content c) sulphur content d) humidity of air 18 For coal fired system the flame length is dictated by a) moisture b) volatile matter c) ash content d) fixed carbon 19 Which one of the following is not true with respect to the role of nitrogen in the ,Net Calorific Value, If the ash content of the fuel is low and rather constant, the calculation can be based on the dry basis Eqn (36) with a typical value of q p,net; however, if the ash content varies quite a lot (or is high) for the specific biofuel then using the equation for dry and ash-free basis (37) with a ,.
