Sep 13, 2018· The coal found in Gujarat is of poor quality and contains only about 35 per cent of carbon. The moisture content in this coal is quite high. It .
Lignites with around 45 % to 55 % moisture require much more heat to remove the moisture. Lignite boilers use recirculated Flue gas from the top of the furnace to heat and remove the moisture. The temperature of the flue gas will be in the order of 800 °C and above. This gives sufficient heat for the high moisture removal. High Volatile Matter.
The problems faced in coal stacks and factors affecting the spontaneous combustion of coal like coalification degree, petrographic composition, moisture content, mineral content, particle size, pyrite content are discussed independently. 1. Introduction Like gas and liquid fuel, coal is a material which can be stored in large quantities

Coal, therefore, is found in a variety of forms depending on the degrees of compression and the depth and time of burial. Decaying plants in swamps produce peat. This has a low carbon and high...
Gondwana coal makes up to 98% of the total coal reserves in India and 99% of the coal production in India. Gondwana coal is free from moisture and contains phosphorus and sulphur The carbon content in Gondwana coal is less compared to the Carboniferous coal that is 350 million years old which is almost absent in India because of its much ...
May 01, 2020· Kolkata: Coal India's daily supplies to the power sector, its biggest consumer, has halved this week compared to daily sales during the beginning of April, prompting unions to suggest drastic cuts in output to reduce losses so that the company has enough money to pay salaries. Total supplies to the sector have slumped almost 70% this month as against April 2019.

Types of coal found in India. Anthracite: It is the highest grade of coal containing a high percentage of fixed carbon. It is hard, brittle, black and lustrous. It is found in smaller quantity in regions of Jammu and Kashmir. Bituminous: It is a medium grade of coal having high heating capacity. It is the most commonly used type of coal for ...
moisture of the coal as it occurs in the unexposed seam, where the relative humidity is 100 %. As mentioned above, equilibrium moisture provides a fairly accurate estimate of the inherent moisture in high-rank coals but the same is not true for low-rank coals where the equilibrium moisture is usually less than the inherent moisture.
At present India does not have specific emission regulatory SO X and NO X limits. Sulphur content in Indian coal (of Gondwana origin) rarely exceeds 0.5%, although nitrogen is on the higher side. However, particulate emission limits are 150 and 300 mg/Nm 3 for units .
Moisture absorbs heat, so high moisture content in coal reduces the relative efficiency of heating when a coal is combusted. This is why low-rank, high-moisture coals have lower calorific values (Btu/lb) than high-rank, low-moisture coals. Moisture adds weight to coal, and also contributes to spontaneous combustion in low-rank coals, and as ...
Jan 25, 2016· Coal – Formation of Coal – Types of Coal – Peat, Lignite, Bituminous Coal & Anthracite Coal. Carbon content in different types of coal. Importance of each type. Coal Also called black gold. Found in sedimentary strata . Contains carbon, volatile matter, moisture and ash Mostly used for power generation and metallurgy. Coal reserves are six times greater than oil and petroleum reserves.
Rejects are the products of coal beneficiation process after separation of cleans and / or middlings, as a fraction of feed raw coal. Used for Fluidized Bed Combustion (FBC) Boilers for power generation, road repairs, briquette (domestic fuel) making, land filling, etc.

The Moisture in the Coal is both these put together and is the "Total Moisture." A coal sampled at the mines having a moisture of 20%, after storage for a few weeks, when entering the boiler can have moisture of only 8%. 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.
