This machine is entirely a high-tech processing machine which integrates chemical energy means and multiple technologies. It's incredible. In the past, people talked about hydroelectricity generation. However, this is not a pure dream of hydropower generation in the past, but an objective fact converter. Everyone knows this magic converter after seeing it, and it can actually achieve zero pollution. . , releasing energy from fossil fuels and traditional electric energy, what is even more amazing is that its efficiency is more than twice that of an internal combustion engine, and its cost, mainly the cost of producing electricity, actually has advantages over our national grid. . What makes me even happier is that with this our smog problem will be solved. It's our Chinese dream!
For steam turbinesr cooled with water and hydrogen, does the generator need to be charged with hydrogen before turning over? (The generator is not connected to the grid)
From the point of view of usage, the generator in the power station has been greatly improved. It was originally air-cooled and purely air-cooled. Current generators include water cooling, single water internal cooling and double water internal cooling, as well as water-hydrogen cooling (stator water cooling, rotor and air gap hydrogen cooling), and those over 300,000 kilowatts are all water-hydrogen cooled. They all have their own advantages and disadvantages: air cooling is bulky and expensive, and the system is simple. Water-cooled hydrogen cooling is small in size, inexpensive, complex in terms of system, has many fault points, and is not practical.than to use. The excitation system has also been greatly improved. It turns out that the exciter is driven coaxially with two and three excitation levels, and the brushes tend to catch fire and wear out. It is now a statically excited silicon rectifier, with no sparking or wear. etc.
This is not necessary. If there is no network or the conditions are not met, and you want to check the vibration and exercise the auxiliary machine, you can run it fully as long as there is no excitation . current, the heat generation will not be very significant. Say no. In the hydrogen charging state, when the rotor rotates, the internal air flow is circular instead of dead. There are too many cases of starting without hydrogen charging and many power plants. I experienced this during the commissioning phase!
