ethyl chloride

Low pressure steam specific volume is very large, so that the gas turbine unit capacity limitation. But in the running process of the relatively safe. Another is the use of low boiling point substances, such as ethyl chloride, butane, isobutane and freon as generating intermediate refrigerant,solar panel
underground hot water through the heat exchanger, the low boiling point substances vaporize rapidly, using the generated gas into the generator to apply work, after the working fluid from the turbine is discharged into the condenser, and in one of the cooling systems, and to condense into liquid refrigerant recycling use.
This method is called" the middle working method", this system is called " dual system" or" duplex biomass power generation system".solar module
The power generation mode has poor safety, if the power system in the closed slightly leaking, refrigerant escape easily after accident.
Nineteen ninties metaphase, Israel omata ( Ormat ) company to the geothermal steam and geothermal power generation two system become, to design a new named combined cycle geothermal power generation system, the unit has been in the world some countries of installation and operation, the effect is very good.
Combined cycle geothermal power generation system is the greatest advantage, can be applied to more than 150 DEG C high temperature geothermal fluid ( including hot brine ) power, after a power fluid, in does not lower than 120 DEG C under the condition,solar cell then enters the duplex matter power system, two work, it is to make full use of the geothermal fluid heat energy, which can improve power generation efficiency, and can be used after a generation after the emission of tail water reuse, resource is saved greatly.
