What fuel is used for the thermal standby of GE reactors?
Thread Content
Dear classmates, I would like to ask what kind of fuel is generally used in domestic GE boilers for hot standby – natural gas, liquefied gas, or something else? What is the hot standby temperature? And how many hours does it usually take to go from hot standby to operation (at, for example, 50% load)? Thank you all!
In fact, a water-coal slurry gasification furnace does not need to be kept in a hot standby state; if hot standby is required, in my opinion any fuel can be used – it depends on the fuel used for heating. According to their original design, liquefied gas and kerosene were intended to be used; but considering the plants that are currently in operation, this is not necessary at all. It is recommended to use the same fuel for heating as that which is used for bringing the furnace up to temperature.
In the normal heating process of industrial gasifiers, liquefied gas is used below 600 degrees, while diesel is used above 600 degrees.
During the heating up of a conventional plant gasification furnace, liquefied gas is used before reaching 600 degrees at the start-up phase, while diesel is used after that temperature. During normal operation, synthetic off-gas or liquefied gas is used before 600 degrees, and diesel is used after that temperature
Initially, when starting the operation, the temperature is increased according to the heating curve provided by the refractory brick manufacturer; generally, liquefied gas is used before reaching 500-600 degrees, after which diesel is used
