Jun 16, 2015· The coal tar (active ingredient) is added to a diluent (petroleum) currently containing no coal tar. ALIQUOT METHOD (ALLIGATION) Alligation is a method that is particularly useful when mixing two or more preparations of known strengths to prepare a mixture of an intermediate desired strength.

The Proximate Analysis of any coal i.e. the % content of Moisture, Ash (A), Volatile Matter (VM), Fixed Carbon (FC) – also Sulphur (S) and Calorific Value (CV) – can be expressed on any of the above bases. Conversions To obtain: multiply ar by: Air Dry Dry Basis As Received

Total moisture or water in coal consists of the surface and residual moisture left over in the coal after determining the air-dried loss (Speight, 2005). Moisture loss is coal-maceral dependent and in order of vapor pressures of moisture increases from vitrain (least loss) …

Measuring energy in food. Food calories are a measure of energy in food. One food calorie is equal to 1,000 calories, or 1 kilocalorie. For example, the energy in a 300-food calorie ice cream cone is about the same as the amount of electricity required to light a 100-watt incandescent light bulb for 3.5 hours.

can be calculated on a saturated base, an actual base, or a saturated base depending on contract requirements. The saturated or the dry heating value factor at a pressure base of 14.73 PSIA and 60 degrees Fahrenheit can be calculated from the partial pressure of water vapor, 0.2563 PSIA, at …

When the inherent moisture increases, the pulverized particles in the dry feed system tend to agglomerate, resulting in unsteady feeding of the coal. Based on a study conducted with a KBR transport gasifier, inherent moisture of greater than 28% for a particle size distribution between 200–800 µm can result in an unsteady operation of lock ...

From GAR to NAR : The difference between net and gross as received (NAR v/s GAR) specific energy values is the latent heat of the water vapour which lowers the effective calorific value in the ...

After considering the conversion efficiency in a power plant we require an heat input of (3600 / 33.44% ) 10765 kJ/ kw hr. Coal Quantity. Since coal has a heat value of 20,000 kJ/kg, for producing one kw.hr we require (10765 / 20000) 0.538 kg of coal. This translates to (0.538 x 100 x 1,000) 53800 kg/hr (53.8 T/hr) of coal for an output of 100 MW.

If the Coal sampled at the mines has an HHV of 18800 kJ/kg the same coal at the boiler will have a higher HHV. This is because the percentage of combustibles in one kg is more. Based on a simple proportion calculation, multiplying by a factor [100-8]/ [100-20] the HHV will be 21620 kJ/kg. In real life, Coal analysis takes place in the laboratory.

Dear Sir. Concerning your issue about the elemental and proximate analysis, wet and dry basis . In the proximate analysis, moisture, ash and volatile matter are determined.

emitted from boilers fueled on coal or oil is primarily inorganic in nature. 1.1.3.2 Sulfur Oxides4-Gaseous SO x from coal combustion are primarily sulfur dioxide (SO 2), with a much lower quantity of sulfur trioxide (SO 3) and gaseous sulfates. These compounds form as the organic and pyritic sulfur in the coal are oxidized during the ...

PF = pressure base to convert from PT = pressure base to convert to. Note: The number of cubic feet in a Mol is pressure base sensitive. The standard per the Gas Processors Association is 379.49 cubic feet at a pressure base of 14.696. The formula to convert the standard to a different pressure base is as follows: 379.49 times (14.696 divided ...
