Description
Technical field
The present invention relates to gas transmission and distribution and application fields more particularly to a kind of fuel gas of safe and reliable low energy consumption to prize.
Background technique
The major function of compressor station is gas pressurized to improve the conveying capacity of pipeline.Current natural gas transmission and distribution situation is come
It sees, many compressor stations have all selected combustion drive compressor, and compressor runs the consumption mainly by natural gas to support, so needing to set
The fuel gas for setting a kind of safe and reliable low energy consumption is prized to depressurize to natural gas sled to natural gas, then will be natural after decompression
Air lift supplies compressor and uses.The case where cooling will cause due to natural gas decompression, while in order to be also needed to compressor combustion gas
The relatively high temperature of turbine improves efficiency of combustion, needs to increase heating link.General compressor station operating cost accounts for natural gas transportation
50% or so of the total running cost of pipeline, it is urgently to be resolved that reduction compressor station energy consumption cost just becomes Long-distance Transmission Pipeline system
Matter of utmost importance.Therefore right letter shoot line is always transported in a kind of design of the fuel gas of safe and reliable low energy consumption of compressor station sled process flow
Working cost has a great impact.
In a kind of technical flow design of the fuel gas sled of safe and reliable low energy consumption of traditional compressor station, usual compressor station is used
Fuel gas should meet requirement of the gas turbine to makings, pressure and flow, and fuel gas gas source is generally single source of the gas, be separated by filtration
Gas is taken on device downstream header and bypass line of more standing, carrys out temperature degree generally all at 10 DEG C or so；Pass through heating device temperature in future
Degree is promoted, and is first heated and is cooled down in pressure regulation, final to guarantee temperature required for gas turbine, needs to consume in this process
Big energy is heated.
In a kind of technical flow design of the fuel gas sled of safe and reliable low energy consumption of traditional compressor station, usual voltage-regulating system
Form generally use safety cut-off valve+monitoring pressure regulator valve+work pressure regulator valve, general setting two-way, master is worked as on main road and spare road
Main road monitoring pressure regulator valve replaces work when road pressure regulator valve breaks down, if main road monitoring pressure regulator valve also breaks down, main road
Self-operated safety valve stop valve can cut off upstream and carry out gas, automatically switch to spare road, the same main road of spare operation order, when spare
When the stop valve cutting on road, the gas supply at whole station stops, and then will affect the operation of gas turbine and entire compressor station, causes
Biggish economic loss.
In a kind of technical flow design of the fuel gas sled of safe and reliable low energy consumption of traditional compressor station, the safety of general export
Valve is when safety cut-off valve breaks down, when being unable to normal cutoff, to carry out superelevation as last one of safety guard
The protection of pressure.The setting of safety valve generally is all the way, without spare road；When safety valve need third party demarcate during, system without
Safety valve, can not safeguards system safety.
In a kind of technical flow design of the fuel gas sled of safe and reliable low energy consumption of traditional compressor station, container nitrogen and steaming
The blowdown of vapour purge system is that the blowdown with station is summarized.When general operation, after emptying of stopping the supple of gas or steam, with residual air blowdown, row
Cleaning purging is carried out with the steam of blow valve port injection high temperature after dirt, carries out displaced air with nitrogen after purging, then with naturally
Gas displacement nitrogen；There are different medium sewage draining exits uniformly to summarize for this design, and the medium of different design conditions is at work
It is possible that occurring mutually going here and there, safe hidden danger is generated.
In a kind of technical flow design of the fuel gas sled of safe and reliable low energy consumption of traditional compressor station, the temperature of heater
Collection point is after heater, before pressure regulation.According to the temperature drop that the pressure drop of pressure regulator valve generates, retrodict required for calculating pressure regulation valve inlet
Temperature, the maximum temperature heated required for often considering according to most severe harsh operating condition in calculating process passes through temperature
Degree detection instrument detection temperature is either with or without the temperature for being heated to design and wanting.This set not can guarantee final entire sled block
Outlet temperature, outlet temperature can due to media components and operating parameter change and fluctuate, such as work as the practical ratio of inlet pressure
When lower, the entire outlet temperature for prizing block can be excessively high, and biggish energy consumption is caused to waste.
