Let's revisit what we mentioned above. The energy generated by the complete combustion of one kilogram of coal is said to be equivalent to 8.14 kilowatt hours of electricity. However, the actual combustion process cannot reach 100%. At the same time, the efficiency of power generation is calculated based on the most advanced power generation technology. If the efficiency of electricity production is set at 48%, then the electricity produced by 1 kg of coal = 8.14 × 98% ×. 48% = 3.83 kilowatt hours. The electricity produced by one ton of coal is then 3,830 kWh. This result is not much different from the actual situation of the power plant. The National Development and Reform Commission has made adjustments to thermal power plants whose coal consumption for thermal power generation exceeds 305 g/kWh. Per 1 kg of coal is less than 3.2 kWh, this is considered alow level of efficiency.
So overall, a ton of coal produces electricity at a temperature of about 3,800 degrees, which is a relatively fair number. However, there will be other losses in the actual process, but the lack of data could be limited. one hundred or two hundred degrees. The fluctuations between them will not differ much. In the future, with the advancement of technology, the efficiency of thermal power generation will also move to a higher level, and one ton of coal will then produce more electricity.
Today, a ton of coal costs 800 yuan. One ton of coal generates 3,830 kilowatt hours of electricity. Calculated as an average of 0.4 yuan per kilowatt hour, 3,830 multiplied by 0.4 is 1,532 yuan minus 800. is equal to 732. Then, one ton of coal in a power plant can generate a profit of about 732 yuan< /p>.
