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.
Pulverised coal (for better and easier combustion), is burned in a boiler where the Heat Energy is converted to Thermal and Pressure Energy of Superheated Steam. This is then Converted into Mechanical Energy by Driving large Steam Turbines.
