Approximately how many
tons of lignite would be required to
produce the amount of heat generated
by one ton of anthracite coal?
To find out approximately how many tons of lignite would be required to produce the same amount of heat as one ton of anthracite coal, we need to compare their heating values. The heating value of a fuel refers to the amount of heat energy that can be obtained by burning a specific amount of that fuel.
Anthracite coal has a higher heating value compared to lignite. The heating value of anthracite coal typically ranges from 24 to 35 million British thermal units (MMBTU) per ton. On the other hand, the heating value of lignite is generally lower, usually around 8 to 14 MMBTU per ton.
To determine how many tons of lignite would be needed, we can calculate the ratio of their heating values. Let's assume the heating value of anthracite coal is 30 MMBTU per ton.
Ratio of heating values = Heating value of lignite / Heating value of anthracite coal
Ratio = 30 MMBTU / Heating value of lignite
Assuming the heating value of lignite is 12 MMBTU per ton, the ratio would be:
Ratio = 12 MMBTU / 30 MMBTU = 0.4
Therefore, it would take approximately 0.4 tons of lignite to produce the same amount of heat generated by one ton of anthracite coal.
To determine the approximate amount of lignite required to produce the same amount of heat as one ton of anthracite coal, we need to consider the energy content or heating value of both types of coal.
1. Anthracite coal typically has a heating value of about 24 million British thermal units (BTUs) per ton.
2. Lignite coal, on the other hand, has a lower heating value, usually ranging from 9 to 17 million BTUs per ton, depending on the quality.
To calculate the approximate amount of lignite required, we can use a ratio by dividing the heating value of anthracite coal by the heating value of lignite coal.
Let's assume the heating value of lignite coal is 12 million BTUs per ton.
Ratio = Heating Value of Anthracite Coal / Heating Value of Lignite Coal
Ratio = 24 million BTUs / 12 million BTUs
Ratio = 2
Therefore, it would take approximately 2 tons of lignite coal to produce the same amount of heat as one ton of anthracite coal. Please note that this is an approximation as the actual heating values of lignite coal may vary.
