When in 1939 war did break out between Germany on the one hand, and Britain and France on the other, President Franklin D. Roosevelt dutifully invoked the Neutrality Acts. However, he believed that this was a fundamentally different war from World War I.
Another advanced coal technology is coal gasification, a process in which coal is converted to a gas (called syngas) before it is burned, making it easier to separate CO2 as a relatively pure gas before power is generated.
Simply put, coal-fired electricity generation is a five-step process: 1  Thermal coal (either black or brown) that has been pulverised to a fine powder is burned. 2  The resulting heat is used to turn water into steam.  The steam at very high pressure is then used to spin a turbine, connected to an electrical generator.
