What is proximate and ultimate analysis of coal?
The "ultimate" analysis" gives the composition of the biomass in wt% of carbon, hydrogen and oxygen (the major components) as well as sulfur and nitrogen (if any). The carbon determination includes that present in the organic coal substance and any originally present as mineral carbonate. The hydrogen determination includes that in the organic materials in coal and in all water associated with the coal. All nitrogen determined is assumed to be part of the organic materials in coal. The "proximate" analysis gives moisture content, volatile content,consisting of gases and vapors driven off during pyrolysis (when heated to 950 C), the fixed carbon and the ash,the inorganic residue remaining after combustion in the sample and the high heating value (HHV) based on the complete combustion of the sample to carbon dioxide and liquid water. Proximate analysis is the most often used analysis for characterizing coals in connection with their utilization.

What is the difference between ARB and GAR in Coal Analysis?
ARB (as received basis) refers to the analysis of coal as it is received at the power plant, including the moisture content. GAR (gross as received basis) refers to the analysis of coal without adjusting for moisture content. So, GAR will have a higher value compared to ARB because it does not account for the moisture content that is present in the coal.
How much energy is generated from coal?
The amount of energy generated from coal can vary based on factors such as the type and quality of coal, the efficiency of the power plant, and the technology used. On average, coal-fired power plants convert about 33-40% of the energy in coal into electricity.
What is the meaning of adb in coal specification?
ADB stands for Air Dried Basis in coal specification. This term refers to the moisture content of coal after it has been air dried under specific conditions. It is used to standardize coal analysis and compare the energy content of different coal samples.

How do you identify the grade of coal bitumen vs anthracite from a mine?
Coal is graded based on its carbon content and calorific value. Bituminous coal typically has a higher carbon content and energy value compared to anthracite. One way to identify the grade is to conduct proximate and ultimate analysis tests on the coal samples, which can provide detailed information on its composition and quality. Consulting with a coal expert or using specialized equipment can also help determine the grade accurately.
What are examples of proximate analysis?
Proximate analysis includes determining the moisture content, volatile matter, fixed carbon, and ash content of a sample. It provides important information about the composition and energy content of materials such as coal, biomass, and solid waste. These parameters help in understanding the suitability of a material for various applications, such as combustion or conversion to energy.
Determine the calorific value of fuel using dulong's formula?
Theorotical value can be calculated using the results of ultimate analysis of coal . Based on the GCV of combustible value of coal.

Difference between fixed carbon and carbon in ultimate analysis?
There will be difference in value of fixed carbon and carbon in ultimate analysis as some carbon is lost in hydrocarbons in volatile matter. Fixed carbon is arrived by substracting the volatile matter. Utimate analysis ditermines the total carbon content which includes the carbon present in volatile matter. Fixed carbon is useful to know how much coke can be generated out of coking coal.
