SOURCES OF ENERGY.ppt . ... -In thermal power plants the heat energy produced by burning fossil fuels like coal, petroleum or natural gas is used to heat water and change it into steam which rotates the turbines of generators to produce electricity. c) Hydro power plants:-In hydro power plants water from rivers are stored by constructing dams.
Properties of Coal • Coal properties are evaluated by different methods. • The most commonly used methods are Proximate and Ultimate analysis of the coal. • Proximate analysis gives the Moisture, Ash and Volatile matter, while the Fixed Carbon is found by difference. • Ultimate Analysis gives the elemental composition of the coal. • Other methods like Macarel analysis is also used ...
analysis of the whole-coal samples, are given in Table 4.3. The XRF technique used is regarded as only semi-quantitative for sulphur, hence the sulphur contents are not reported. The results given in Table 4.3 also indicate that there are some variations in the chemical composition of the coal used in the study. ...
tailed coal classification system was needed and that it should be based on bed-by-bed analysis of thicknesses of coal and overburden, reliability (distance from control points) of areal data, rank of coal, and several chemical parameters related to determining quality and usage. As a result, ongoing programs of the Geological Survey and ...

The term maceral was first used by Stopes in 1935 for a component of coal detected under a microscope. Over the years, the ICCP has established standard rules for maceral analysis, maceral definitions and classifications. This atlas uses the most current maceral classification as regulated by ICCP (ICCP System, 1994).
Jan 25, 2014· • Coal and petroleum are sources of energy that are non-renewable. They are made in nature, a long time before and they will finish a long time use. 3. • Coal is a combustible, sedimentary, organic rock, formed from vegetation. In other words coal is a fossil fuel created from the remains of plants that lived millions of years ago.
Group F. Atmospheres containing combustible carbonaceous dusts that have more than 8 percent total entrapped volatiles (see ASTM D 3175, Standard Test Method for Volatile Matter in the Analysis Sample of Coal and Coke, for coal and coke dusts) or that have been sensitized by other materials so that they present an explosion hazard.
REASONS FOR CLASSIFICATION OF COAL ... Calculations of results of analysis of coal (solid fuels) Coefficient of conversion: Type of conversion Raw r Analytical a Dry d Dry ash free daf From raw state r 1 1−Wr −Wa 1 1−Wr 1 1−Wr −Ar 1 From analytical
Ultimate analysis results and mineralogie composition data are reported in tab. 1 and 2.Agglomerability properties of both coals are summarized in table 4.Polish coal agglomerates easier than Illinois n.6, but, taking into account their different liberation degree (fig. 1), Illinois n.6 seems to allow a better selectivity.Results from microcalorimetric analysis, permit different conclusion levels.
Jun 15, 2011· Root Cause Analysis and Incident Investigation Date: June 15, 2011 C-4 A team should conduct a root cause analysis. At least one member of the team should have had training in facilitating a root cause analysis team in the methodology to be used. An employee and employees' representative should be on the team.
classification of coal ppt. ... classification of coal macerals is highly botanical and can be done only with the aid of a microscope. 2.3.5 The macroscopic study and classification of coals, on the other hand, while not as fundamental, is easier to deal with. Coal has long been recognized to ...
Sep 13, 2018· Classification of Coal. Coal can be classified on the basis of carbon content and time period. Types of coal on the basis of carbon content. Anthracite is the best quality of coal which carries 80 to 95 per cent carbon content. It ignites slowly with a blue flame. It has the highest calorific value. It is found in small quantity in Jammu and ...
Coal classification Coal is classified into three types as follows, even there is no clear demarcation between them: 1. Anthracite 2. Bituminous 3. Lignite. The Coal is further classified as semi-anthracite, semi-bituminous and sub-bituminous. the anthracite is the oldest coal from a geological perspective.
Flowsheet of sample preparation and chemical analysis of coal_____ 7 3.

Jul 11, 2013· CLASSIFICATION BASED ON PROXIMATE ANALYSIS 2. Frazer's classification: In 1877, he used fuel ratio to classify coal as given: Coals of lower rank than bituminous were not considered Study was on only Pennsylvania coal. Sl no Coal type Fuel ratio 1. Anthracite 100-12 2. Semi anthracite 8-12 3. Semi bituminous 5-8 4. Bituminous 0-5 15.
Proximate and Ultimate Analysis of Power Plant Coal The proximate analysis determines only the Fix carbon, Volatile matter. The ultimate analysis is useful in determining required air for combustion for power plants coal. ... Coal Classification, Blending, and Requirement.
• Review all the relevant information on Botswana coal resources with the aim to advise on how to better utilize the country's coal resources now and in the future by developing an approximate schedule of coal production for multiple uses, and provide Government with a current and future market forecast for coal .
The ultimate analysis determines all coal component elements, solid or gaseous and it needs properly equipped laboratory with skilled chemists. It is useful in determining the quantity of air required for combustion and the volume and composition of the combustion gases.
Coal Centre – Coal sampling and analysis standards 4 Abstract Each year, billions of tonnes of coal are traded in regional and international market for use in power generation, steel and cement making, and many other purposes. In commercial operations, the price of coal
Ultimate analysis is determined also using set procedures for ash, carbon, hydrogen, nitrogen, oxygen, and sulfur contents, which are reported as percent on as-received and moisture- and ash-free bases. Ultimate analysis is important for classification of coal by rank. Both analyses are important for utilization, commercial, and industrial ...
