Name all the qualities of coal the Percentage of carbon present in them.
Answers
Answer:
firstly it is called a peat:- Peat is not a coal but after years it is converted into lignite.
Lignite: Lignite coal also called aka brown coal, is the lowest grade coal with the least concentration of carbon.it has approx. 20 to 35 % of carbon.
Subbituminous: Subbituminous coal is black in color and dull (not shiny), and has a higher heating value than lignite.it has approx.40 to 60% of carbon.
Bituminous: Bituminous usually has a high heating value and is the most common type of coal used in electricity generation. Bituminous coal appears shiny and smooth when you first see it, but look closer and you may see it has layers.it has 60 to 80 % carbon.
Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter.it has 92 to 98 % of carbon
Answer:
Explanation:
*Anthracite coal is a dense, hard rock with a jet-
*86% and 98% carbon by weight, & it burns.
*Bituminous coal (in Indiana), contains between.
*69% & 86% carbon by weight.
*Sub-bituminous coal contains less carbon, more.
*Lignite coal, or brown coal, is a very soft coal that.
*Contains up to 70% water by weight. Emits more.
