Description
Technical field
The invention belongs to combustion engine control technology fields, specifically disclose a kind of GE combustion engine starting method.
Background technique
GE combustion engine is a kind of gas turbine, using the gas continuously flowed as working medium impeller high speed rotation, by fuel
Energy conversion is the internal combustion type dynamic power machine of useful work, belongs to a kind of rotary vane type Thermal Motor.GE combustion engine some is with coal
Gas is fuel, before coal gas is passed through GE combustion engine by gas compression pump, is needed the air displacement in GE combustion engine pipe network first
For the coal gas of pressurization；Encountering fire source due to being mixed into air in coal gas can explode, and the air in pipe network can first replace nitrogen, then
It is replaced into coal gas.
Two steps are usually required when GE combustion engine starts at present, the first step is first by the air displacement in gas compression pump pipe network
For coal gas, starting gas compression pump boosts to the coal gas in its pipe network after coal gas replacement is qualified, opens after reaching relevant pressure
Beginning second step；Second step is to be replaced using the coal gas to pressurize in gas compression pump to the pipe network in GE combustion engine, during this
It needs every time first to pressurize in the pipe network for replacing GE combustion engine again to the coal gas in gas compression pump pipe network, until by GE combustion engine
After coal gas in pipe network is replaced completely, the coal gas to pressurize in GE combustion engine pipe network reaches combustion chambers burn, generates the gas of high temperature and pressure
Body pushes wheel rotation, thus output mechanical energy.
Above-mentioned GE combustion engine start-up course, GE combustion engine need to wait the starting of gas compression pump, boost process, when GE combustion engine pipe
GE combustion engine could be started after coal gas replacement qualification in net, and gas compression pump starting, boost process need certain time, thus
The starting of GE combustion engine is caused to need to consume a longer time.
Summary of the invention
The purpose of the present invention is providing a kind of GE combustion engine starting method, longer to solve the current GE combustion engine starting consuming time
The problem of.
In order to achieve the above object, a kind of base case of the invention are as follows: GE combustion engine starting method, comprising the following steps:
(1) protective gas is replaced, is protective gas by the air displacement in GE combustion engine pipe network and in gas compression pump pipe network；
(2) coal gas is replaced, the protective gas in GE combustion engine pipe network and in gas compression pump pipe network is replaced into coal gas；
(3) gas pressing, starting gas compression pump pressurizes to coal gas, while starting GE combustion engine and burn.
The beneficial effect of this base case is:
At present in the start-up course of GE combustion engine, in order to guarantee that coal gas reaches the pressure of combustion chamber, coal gas all leads to upon compression
Enter in GE combustion engine, since coal gas is flammable explosive gas, usual those skilled in the art will not change GE combustion engine easily and be formulated
Starting method；And applicant has feasibility by theoretically analyzing, studying discovery after forming this programme, carries out simultaneously
Test repeatedly to ensure that this programme is feasible can't lead to the problem of explosion；Finally improved by rigorous calculating and test
The starting step of GE combustion engine.
In the coal gas in gas compression pump network management without reducing coal gas in coal in pressurization just network management of the displacement to GE combustion engine
The process pressurizeed in air compressor network management, thus reduce GE combustion engine and start the needed to wait for time, it is opened to reduce GE combustion engine
Total time is moved, the time expended needed for the starting of GE combustion engine is reduced.Compared with prior art, this method effectively reduces GE combustion engine
The time of start-up course, so that GE combustion engine is capable of fast starting.
Further, protective gas described in step (1) is nitrogen.Nitrogen chemical property wave not living, can preferable discharge pipe
Air in net, and nitrogen largely exists in the Nature, easily obtains, is at low cost.
Specific embodiment
It is further described below by specific embodiment:
Embodiment 1
A kind of GE combustion engine starting method, comprising the following steps:
(1) protective gas is replaced, is protective gas by the air displacement in GE combustion engine pipe network and in gas compression pump pipe network,
Protective gas selects nitrogen in the present embodiment；
(2) coal gas is replaced, the protective gas in GE combustion engine pipe network and in gas compression pump pipe network is replaced into coal gas；This mistake
Diffusion valve before enforced opening GE combustion engine fuel shut-off valve and GE combustion engine valve station in journey, using gaspipe network pressure 9kpa to coal gas pressure
Contracting machine pipeline and GE combustion engine pipeline carry out drawing logical displacement.
(3) gas pressing, starting gas compression pump pressurize to coal gas, while starting GE combustion engine burning coal gas.
GE combustion engine opens machine to oil and cuts 40 minutes gas enabled condition used times, and gas compression pump can also boost at the same time
Gas is cut with GE combustion engine completion oil to atmospheric pressure 2.3MPa is cut.Therefore the present embodiment operation GE combustion engine open the machine time be 40 minutes or so,
Waiting time swap is saved.
Comparative example 1
A kind of GE combustion engine starting method, comprising the following steps:
(1) protective gas is replaced, is protective gas by the air displacement in GE combustion engine pipe network and in gas compression pump pipe network,
Protective gas selects nitrogen in the present embodiment；
(2) coal gas is replaced, the protective gas in gas compression pump pipe network is replaced into coal gas；
(3) pressurized gas and displacement coal gas, start gas compression pump, gas compression pump opens power 16000kw after machine, by coal
Gas lift is pressed onto corresponding displacement pressure and needs 15-25 minutes, is replaced in GE combustion engine after coal gas boosts to relevant pressure；
(4) step (2) are repeated by after the coal gas whole displacement for boosting to relevant pressure of the protective gas of GE combustion engine, are started
GE combustion engine.
Embodiment 1 and comparative example 1 are used with a turbine type GE combustion engine and with a gas compression pump, and reality is respectively adopted
The method starting GE combustion engine for applying example 1 and comparative example 1, it can be found that due to the laggard line replacement of gas compression, embodiment in comparative example 1
1 saves at least 15-25 minutes than comparative example 1.Main cause is that more coal gas boosting step, coal gas boosted in comparative example 1
Journey needs 15-25 minutes.
