(.#A.068).- Even more charcoal burned. August 28, 2019.
Even more charcoal burned. August 28, 2019.
As the world turns its eyes to fires in the Amazon rainforest, another environmental news story went unnoticed: we learned that coal consumption increased by 1.4% worldwide in 2018.
This increase, documented by the Statistical Report on World Energy, published by BP this summer, is mainly due to the countries of Asia and the Pacific (+ 2.5%), which are responsible for three quarters of demand. This fossil fuel remains the most used means in the world for producing electricity and is even more polluting than gas or oil.
3772 billion tonnes of coal consumed worldwide.
Coal mines
Their exploitation generates large quantities of CO2 and can pollute groundwater.
Operation of a coal-fired power plant :
According to Enerdata, coal emits 3.5 tonnes of CO2 per tonne of energy consumed: 1.5 times more than gas, 1.3 times more than oil.
Crusher
The coal is ground into fine particles.
Water supply.
Pump
Feeds water to the boiler.
Sprayer
Supplies coal to the boiler.
Boiler
The heat produced by burning coal heats water-filled pipes and turns it into steam.
Turbine
The steam turns the turbine.
Generator
Transform the energy of the turbine into electricity: the goal of the whole operation.
Precipitator
Recover coal particles.
Transformer
Modifies the voltage and current values, so that it can be distributed by the transmission lines.
Discharge basin
The residual combustion ash is mixed with water before being discharged into a tank.
Fireplace.
