May 15, 2019· High calorific value and low calorific value based question come in exam. In this video, I have explained how to find HCV and LCV of a fuel. If you have any doubts related to this video then ...
The higher heating value (also known as gross calorific value or gross energy) of a fuel is defined as the amount of heat released by a specified quantity (initially at 25°C) once it is combusted and the products have returned to a temperature of 25°C, which takes into account the latent heat of vaporization of water in the combustion products.

Heat liberated on burning 2 Kg coal = 14114 Kcal. 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.
Mar 06, 2015· Mar 6 2015. Coal, as it is commonly known, is a solid fossil hydrocarbon fuel material. The gross calorific value of coal is frequently used when determining the total calorific value for a specific amount of coal for fuel value purposes or when establishing the rank of classification of the coal material.
Jan 07, 2010· The difference between LCV and HCV (or Lower and Higher Heating Value, or Net and Gross) is clearly understood by all energy engineers. There is no 'right' or 'wrong' definition. Commercial CCGT plants are just under 50% efficient, as a weighted .
Net calorific value assumes the water leaves with the combustion products without fully being condensed. Fuels should be compared based on the net calorific value. The calorific value of coal varies considerably depending on the ash, moisture content and the type of coal while calorific value of .
Gross calorific value, also known as the higher calorific value (HCV) of bagasse, is calculated from the following formula: HCV=[19605 (moisture % sample) (ash % sample) (brix % sample)] The net calorific value, also known as the lower calorific value (LCV), assumes that the water formed by combustion and also ...

This conversion factor is termed the calorific value or heating value of the fuel. Typical expression of the values would be 26 gigajoule/tonne (GJ/t) for a coal or megajoule/cubic metre (MJ/m3) for a gas. In this Manual the term "calorific value" will be used although "heating value" is also in widespread use.
Coal and coke determination of gross calorific value by the bomb calorimetric method, and calculation of net calorific value .; Animal feeding stuffs, animal products, and faeces or urine determination of gross calorific value .
Moreover, oxygen is in combined form with hydrogen in coal and thus, hydrogen available for combustion is lesser than actual one. An increase in 1% oxygen content decreases the calorific value by about 1. 7% and hence, oxygen is undesirable. Thus, a good quality coal should have low percentage of oxygen.
v (gross) or Net Calorific Value (Gross Heat of Combustion at Constant Pressure) Q p (net). Relation between heating values . The difference between the two calorific or heating values depends on the chemical composition of the fuel. In the case of pure carbon or carbon monoxide, the two heating values are almost identical, the

The gross calorific value (often referred to as the higher heating value (HHV), gross energy or upper heating value) is determined by bringing all the products of the combustion of a sample back to the original precombustion temperature, condensing any vapour produced.
Gross and Net Calorific Value Gross Calorific Value (GCV) It is also called higher calorific value (HCV) and is defined as the total amount of heat produced when a unit quantity (mass/volume) of fuel is burnt completely, and the products of combustion are cooled to room temperature. Usually all fuels contain hydrogen.
The efficiency is dependent, among others, on coal quality parameters, since the efficiency of the boiler is a function of gross calorific value and content of ballast in coal.
