A steam generator (commonly known as a boiler) is a mechanical device that USES the heat energy of fuel or other sources to heat water into hot water or steam.
The original meaning of the pot refers to the water container heated on the fire. The furnace refers to the place where fuel is burned. The boiler includes the pot and the furnace.
On September 20, 2014, the steam generator of the core equipment of the high-temperature gas-cooled reactor nuclear power plant of the National Science and Technology Major project completed the installation of the first set of spiral coil assembly, marking a breakthrough in the main manufacturing process bottleneck of the high-temperature gas-cooled reactor steam generator in China.
