Special woods electricity generation system.
Background technique
In recent years, usage amount of the cryogen based on liquefied natural gas in China is significantly promoted, and is widely applied
In fields such as chemical industry, power generation, medical treatment, communications and transportation, heating.In at the international level, production capacity of the liquefied natural gas in various countries is quick
It is promoted, it is estimated that, it will jump to the year two thousand thirty natural gas dosage to non-renewable energy second.2017, China's liquified natural gas import
Up to 38,000,000 tons, and still keep ascendant trend.According to national energy strategical planning, the year two thousand twenty is arrived, natural gas is primary in China
Accounting in the energy will increase to 10% or more.In current natural gas transaction, the nearly one third for total amount of trading is with the day that liquefies
The form of right gas is transported, this portion of natural gas, which need to could be put into local liquefied natural gas vaporization station by re-vaporization, to be made
With or be delivered to user terminal.In this process, liquefied natural gas will discharge the cooling capacity of about 830-860kJ/kg.In tradition liquefaction day
In right gas Vaporizing Station, this part cooling capacity is usually taken away by seawater, and significant wastage is caused.
The Land use systems of cold energy of liquefied natural gas mainly include that cold energy generation, air separation, freezer, air-conditioning and low temperature are supported
It grows, cultivate.In many cold energy of liquefied natural gas recycling forms, cold energy generation technology can be divided into two according to its principle difference
