Another tool included in the software must be the possibility of visualizing the flow of biomethane and natural gas with different calorific values in the different parts of the gas grid.
indicates that calorific values of chamalnag coals were higher as compared to that of Duki and salt range.
This trend is more apparent for samples with low calorific values (samples 1-5).
Oxygen Trim is an integral part of the ETC6009 and is designed to offset the variable calorific values associated with bio and off-gases.
- LBPC is a production license, located within the Balikpapan geological formation with sub-bituminous coal at potentially economic calorific values.
The calorific value of char resulting from pine wood was 26.5 MJ/kg after 5 minutes of heating; after 10 min 30.9 MJ/kg; after 20, 30 and 45 minutes of heating, the calorific values were 34.1 MJ/kg, 34.1 MJ/kg and 34.0 MJ/kg, respectively.
where [Q.sub.i] are the net calorific values of the separate components per unit volume under the given conditions (e.g., normal) and [Y.sub.i] are the volume fractions of the components.
Oil shale (also known as kerogen shale) is a solid combustible organic sedimentary rock with a high ash content, an oil yield higher than 3.5%, and a calorific value generally greater than 4.18 MJ/kg.
Simultaneous firing of fuels can usually be achieved using conventional products but waste and bio-fuels are often characterised by variable availability and inconsistent calorific values. To overcome this an algorithm within the controller software enables safe and efficient combustion to be achieved; an external signal is used to indicate the proportion of waste fuel that should be used across the firing range.
The site for the bulk extraction was selected from the 2008/09 drilling as the main seams here are close to the surface and to the line of oxidation (LOX), but still display good calorific values and relatively low washed coal, ash levels.
Measured moisture content, volatile matter, ash content, fixed carbon, and calorific values of raw coal samples
The gross calorific value ([W.sub.B-] kcal/100 g) of breeding common carp muscle tissue was calculated using physical energy equivalents from the following formula: [W.sub.B] = 5.65 * B + 9.45 * T + 4.15 * W [kcal/g], where B is the protein content in a sample, g/100 g; T is the fat content in a sample, g/100 g; W is the carbohydrates content in a sample, g/100 g; 5.65, 9.45, and 4.15 are physical energy equivalents for proteins, fats, and carbohydrates, respectively, kcal/g.
