A steam generator (commonly known as a boiler) is a mechanical device that uses heat from fuel or other energy 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 the fuel is burned. The boiler includes two parts of the pot and the furnace.
On September 20, 2014, the core equipment steam generator of the national science and technology major special high-temperature gas-cooled reactor nuclear power plant recently completed the installation of the first spiral coil assembly, marking the breakthrough of the main manufacturing process bottleneck of China's high-temperature gas-cooled reactor steam generator.
