This work experimentally evaluates the energy of peatlands in North-eastern India for power plants. Five-peat sites of NE-India has been identified and systematic analyses, such as organic content (20–85%), ash content (15–80%), calorific values (10,600–26150 kJ/kg), etc., have been performed as per the Bureau of Indian Standard (IS) and ...
Indian coal quality shows extensive variation in gross calorific value from coalfields to coalfields and from mine to mine within a coalfield. Furthermore, it is also evident from coal …
On comparison of Indian coals with imported coals, the calorific value of the Indian coals (~4000 kcal/kg) was found to be approximately 60% of the imported coal from Australia and America (~7000 ...
A nation's ability to use its energy resources efficiently and the expansion of its industrial sector are key factors in its prosperity. Most of the industrially developed nations in the world use coal as their main energy source. These resources have been utilized mainly for industrial growth, such as thermal power plants, steel industries, and other associated …
Table 1 Typical characteristics of Indian coal Property Value Ash Content 25 – 55 % Moisture content 4 – 7 % (18 % during monsoon) Sulpher content 0.2 – 1% Gross Calorific value 3100 – 5100 kcal/ kg Volatile matter content 20 – 30 % The ash in Indian coals is mostly high in silica and hence, abrasive. This requires careful
The annual average net calorific value must not be less than 1,700 kcal/kg. The average net calorific value of MSW of Guwahati city is 1833 kcal/kg, which is appropriate for incineration as per Indian regulation and World Bank report value. However, in the rainy season average calorific value of the MSW can fall up to 1203 kcal/kg.
Generally, Indian coals have low calorific value and high levels of inorganic impurities. Also, coal ash is difficult to remove beyond a certain level due to non-homogenously mix nature. The …
Rice straw's energy efficiency can be calculated by dividing its energy output by its calorific value, which may be expressed as the higher-heating value (HHV), wherein latent heat of the water is included, or lower-heating value (LHV). In terms of calorific value, rice straw has an HHV that ranges from 14.08 to 15.09 MJ kg −1, as ...
The Indian coals are a sub-bituminous variety, high in ash content and low in calorific value. The high ash content in Indian coals makes Indian coals more heterogeneous. The moisture and the ash content have a direct impact on the calorific value of the coals. In the present work the moisture, ash content and GCV have been analyzed for the coals obtained …
India, the world's third largest coal producing country, is expected to maintain strong dependency on coal for the coming few decades. The gross calorific value (GCV) of coal is a key yardstick …
value of Indian coal deteriorated [Zamuda et al., 2007]. Indian coal preparation plants typically receive coal with a head ash ranging from 35.0 % to upwards of 50.0 %.
The Indian coals are a sub-bituminous variety, high in ash content and low in calorific value. The high ash content in Indian coals makes Indian coals more heterogeneous. …
In this study, the gross calorific value (GCV) of coal has been estimated using two types of coal analysis data. These are proximate data and spectral reflectance data in visible to near infrared ...
India, the world's third largest coal producing country, is expected to maintain strong dependency on coal for the coming few decades. The gross calorific value (GCV) of coal is a …
The calorific value of coal from pits is determined by analyzing moisture, volatile matter, ash and sulfur content in laboratories. This analysis process imposes a burden on businesses both in terms of time and cost. However, calorific value, in particular, can be determined through simpler methods by using ash and moisture values.
The leaf calorific value (LCV) is an important trait that indicates how efficiently a plant utilizes natural resources to capture energy.However, little is known about the LCV characteristics of plants in arid and hyper-arid environments. To investigate the spatial patterns and variations in LCV of desert plants and their possible causes, we collected 343 leaf …
Indian coal basins and to locally focused subsets of that dataset.
