Therefore, heat liberated on combustion of 1 Kg coal = 14114 7057 Kcal 2 = . [Ans Calorific value of coal = 7057 Kcal/kg]. 2. The gross calorific value of a fuel containing 8% hydrogen was found to be Kcal/kg. Find out its net calorific value if the latent heat of steam is 587 Kcal/kg. Solution NCV = GCV – H × Latent heat of steam.
1: GCV of coal vs. Efficiency graph for AFBC Boiler Figure 1 shows the relation between efficiency and GCV of the coal. Graph shows how the efficiency of boiler increases when the GCV of the coal is increased. Efficiency has been calculated for 3000, 3300, 3600, 5000 and 5800Kcal/kg GVC of coal and efficiencies are,,, and ...
· Net Calorific Value (NCV) also known as lower heating value (LHV) or lower calorific value (LCV) is determined by subtracting the heat of vaporization of the water vapour from the higher heating value. This treats any H 2 0 formed as a vapor. Natural gas prices are decided on .

2 Calculate the GCV and NCV of a fuel from the following. Analysis of coal Procedure for proximate analysis 1. Moisture: Weigh coal sample into dry silica for 1h at 110 0 C. Cool weigh. Calculate the loss in wt. as percentage. % moisture = Loss in weight × 100 Wt. of coal taken • Less moisture content better quality coal 2. Volatile matter: Cover coal left in step 1. Place ...
For gases, these values are converted to NCV in the balance tables. In the IEA Annual Questionnaire both NCV and GCV are reported for coal, while renewables are reported in terms of NCV only. Additionally, classifiion of coals is done on a GCV basis. .

Chemical composition of the coal is defined in terms of its proximate and ultimate (elemental) analysis. The parameters of proximate analysis are moisture, volatile matter, ash, and fixed carbon. Elemental or Ultimate analysis encompasses the quantitative determination of carbon, hydrogen, nitrogen, sulfur, and oxygen. The calorific value Q, of coal is the heat liberated by its complete ...
Problem 7: Calculate GCV and NCV of coal sample having the following composition: C = 80%, H = 7%, S= %, N = %, ash = %.
