### ncv to equivalent efficiency gcv

The calorific value of a fuel is the quantity of heat produced by its combustion – at constant pressure and under “normal” (standard) conditions (ie to 0 o C and under a pressure of 1,013 mbar) The combustion process generates water vapor and certain techniques may be used to recover the quantity of heat contained in this water vapor by condensing it

Should the calorific values be changed from net to gross? The manual from 1982, which recommends using net values, also says that this recommendation may have to be reconsidered if and when it becomes technically possible to recover the latent heat

Jan 07, 2010· The chosen % LCV efficiency for any project is a function of fuel cost as there is a trade-off between efficiency and capital cost, so some low fuel cost areas eg Middle East are still buying 52% LCV efficiency today before any one asks, there would be no point in fitting condensing heat recovery on to a CCGT plant to ‘increase’ its .

is a conversion factor used to convert a fuel quantity between natural units (mass or volume) and energy units (energy content) There are Net Calorific Values (NCV) and Gross Calorific Values (GCV) Depending on the product, we may want to convert using GCV or NCV

Dec 04, 2003· If you don't have one, you'll need to know the combustion process (boiler efficiency or unit heat rates, etc) and make some assumptions to derive an estimate The above is just "back-of-envolope" calculation and I'm sure there are someone who can provide a better solution

Sep 23, 2009· For example, efficiency of a Bagasse fired boiler is about 70% where as that of oil fired boilers is about 85 % Higher moisture content in Bagasse reduces it’s efficiency So better criterion is efficiency based on LCV or NCV This is widely used in Europe and efficiency based on HHV or GCV is used in other parts of the world

The calorific value or heat of combustion or heating value of a sample of fuel is defined as the amount of heat evolved when a unit weight ( or volume in the case of a sample of gaseous fuels ) of the fuel is completely burnt and the products of combustion cooled to a standard temperature of 298 degree K

Dec 23, 2018· Calculation of GCV of fuel:- For calculation of GCV of fuel we need to analysis of fuel and get the constituent of fuel on weight basis Based on the enthalpy of ,

Energy content or calorific value is the same as the heat of combustion, and can be calculated from thermodynamical values, or measured in a suitable apparatus: A known amount of the fuel is burned at constant pressure and under standard conditions (0°C and 1 bar) and the heat released is captured in a known mass of water in a calorimeter If the initial and final temperatures of the water .

The gross calorific value (GCV) of dry bagasse has a mean value of 19605 kJ/kg The gross calorific value (GCV) of wet bagasse is based on the composition of wet bagasse Water has no calorific value and it also absorbs heat being vaporized during combustion The combustion reactions of bagasse as a fuel are as given in Table 3 (Mugadhi 1999)
