Description
Technical field
It is specifically the multifunction burning gas-turbine fuel control unit based on PLC the present invention relates to gas turbine field.
Background technology
Gas turbine is a kind of is converted to the rotary power of mechanical work using the gas that continuously flows as working medium, heat energy
Machinery.In air and the main flow of combustion gas, the only combustion gas of this three big part composition of compressor, combustion chamber and combustion gas turbine
Turbine is circulated, and is commonly referred to as simple cycle.Most of gas turbines use simple cycle scheme.Because its structure is most simple,
And best embody out small volume specific to gas turbine, it is lightweight, start it is fast, few a series of excellent with or without cooling water etc.
Point.Compressor sucks air from ambient atmosphere environment, and process axial-flow compressor compresses be allowed to be pressurized step by step, while Air Temperature
Degree is also corresponding to be improved；Compressed air is pressed to the gas that fuel mixed combustion of the combustion chamber with spraying into generates HTHP；So
After enter back into expansion work in turbine, promote turbine to drive compressor and the rotation of the outer superhigh speed of load rotor one, realize gas
The chemical energy of body or liquid fuel is partially converted into mechanical work, and exports electric work.The waste gas discharged from turbine drains into air certainly
Right heat release.So, the chemical energy of fuel is just converted into heat energy by gas turbine, and partial heat energy is transformed into mechanical energy.Combustion gas
Combustion chamber ignition reliability is mainly determined by the factor such as fuel and air ratio, air velocity when turbine is started, and current
Fuel is difficult to accurately match fuel and air ratio with air mixed control apparatus in gas-turbine combustion chamber, more can not basis
Different operating modes carries out detecting, adjust and matching in real time to fuel in combustion chamber and air ratio, it is impossible to realize fuel and sky
Gas mixing optimal target in real time, combustion chamber ignition poor reliability when causing the existing gas turbine to start, gas turbine is from starting
To slow train process there is also the configuration equivalent of fuel and air it is unreasonable the problems such as, the igniting for seriously hindering gas turbine is reliable
Property.The course of work of gas turbine is that compressor continuously sucks air and compressed it from air；Air after compression enters
Enter combustion chamber, the fuel mixing after-combustion with penetrating as high-temperature fuel gas, flows into expansion work in gas turbine, promoted immediately
Turbine wheel rotates together with compressor impeller.It is high when gas turbine just starts to start or combustion gas, air mass flow are smaller
Warm combustion gas expansion work will be seldom, and because compressor impeller is used for compressed air, turbine wheel is difficult with compressor impeller
The central rotating shaft stalling for rotating and causing together is got stuck, so as to cause failure, can be caused when serious after being connected with gas turbine
The accident of continuous machine.
