Description
Technical field
The present invention relates to gas turbine technology field, be specifically related to a kind of gas turbine online-emulsification oil system and using method thereof
Background technique
Gas turbine is a kind of widely used power plant, can use the pluralities of fuel such as vaporized fuel (as rock gas) or liquid fuel (as diesel oil etc.).When taking fuel oil as fuel, in order to improve combustion efficiency, reducing operating cost and pollutant emission quantity, can evenly be mixed into a certain proportion of softened water in fuel oil, form oil emulsion.
The configuration of oil emulsion, blending have online and off-line two kinds of modes usually.Online-emulsification, measures the fuel oil of needs and softened water in proportion and is evenly supplied to oil-using units after blending namely in real time.Its advantage is that oil-water ratio can regulate in real time by the demand of oil-using units, and shortcoming is that equipment needed thereby is more complicated; Off-line emulsification, for subsequent use after forming oil emulsion by profit by the even blending of fixed proportion.Its advantage is that equipment needed thereby is simple, and shortcoming is that oil-water ratio is fixed, and uses dumb.For gas turbine, its operating conditions is usually changeable, and the optimum emulsification oil ratio example needed for different operating mode is also different, and therefore, gas turbine need be equipped with online oil emulsion system usually.
At present, the gas turbine such as the U.S., Europe producer is the supporting oil emulsion system of the gas turbine product development of self.The gas turbine of China's designed, designed, owing to starting late, applies limited, though therefore have a small amount of research in oil emulsion field, there is no ripe technology or product occurs, limit its application space at civil area.
In the case, research gas turbine online-emulsification oil system and using method thereof, have positive realistic meaning to the overall technology strength of raising China gas turbine industry, the application space of expansion gas turbine.
Summary of the invention
The object of this invention is to provide a kind of modular type online-emulsification oil system and method, according to different gas turbines, provide the oil emulsion of different proportion, to solve the problem of gas turbine when taking fuel oil as fuel, improve combustion efficiency, reduce the discharge of operating cost and decreasing pollution thing.
Technological scheme of the present invention is:
1, system principle
Online-emulsification oil system need to realize three merits such as fuel flow transducer amount, softened water flow sensing tolerance and the even blending of profit substantially can, therefore adopt basic principle shown in Fig. 1 to realize systemic-function.
The control of oil-water ratio, realizes by oil circuit or water route throttling.Profit blending function is then realized by the special blending equipment of technology maturation.Oil emulsion Flow-rate adjustment, should adopt high-precision flow control valve to realize.
2, system structure design
Different user or same user are different to the requirement of oil emulsion system in varied situations, and the demand of existing burning oil emulsion, also has the demand of only non-combusted fuels.In order to adapt to the demand of user better, oil emulsion system adopts the modular construction shown in Fig. 2.
When user only non-combusted fuels time, only need configure flow adjustment module, Flow-rate adjustment module inlet joint is directly communicated with oil sources; When there being oil emulsion demand, Flow-rate adjustment module basis increases oil-water emulsion module.
3, system schema
As shown in Figure 3, modular type online-emulsification oil system is made up of Flow-rate adjustment module and oil-water emulsion module, and two modules are structurally independent, between connected by a pipeline.
Oil-water emulsion module includes low pressure water supply connector 1, electric control valve 2, flow transducer 3, one-way valve 4, oil-water emulsifying device 5, one-way valve 6, oil emulsion outlet connection 7, low pressure fuel inlet fitting 8, flow transducer 9, one-way valve 10, Electric Actuated Stop Valves 11 and Electric Actuated Stop Valves 12.During system worked well, Electric Actuated Stop Valves 11 is opened, Electric Actuated Stop Valves 12 cuts out.Softened water and fuel oil enter oil-water emulsifying device 5 through respective flow transducer 3,9 and one-way valve 4,10.The proportionate relationship of softened water and fuel oil is measured by flow transducer 3,9, is controlled by electric control valve 2 throttling.Oil, water are supplied to Flow-rate adjustment module through one-way valve 6 form oil emulsion in oil-water emulsifying device 5 after.
Flow-rate adjustment module includes adjustment module inlet union 13, motor-drive pump 14, flow control valve 15 and metered oil outlet joint 16.The motor constant revolution of motor-drive pump 14, its fuel pump is positive displacement pump.Fuel pump exports constant flow under motor drives.Flow control valve 15 is the overflow-type modulating valve of constant-pressure drop, can overflow back motor-drive pump 14 import, and the fuel oil needed by gas turbine or oil emulsion exports by from the excess fuel of motor-drive pump 14 or oil emulsion.
When gas turbine is without oil emulsion demand, when only needing to burn pure oil, electric control valve 2 cuts out, oil-water emulsifying device 5 does not work, and Electric Actuated Stop Valves 11 cuts out, Electric Actuated Stop Valves 12 is opened, pure oil is exported by Flow-rate adjustment module, is directly fed to gas turbine by metered oil outlet joint 16.
When gas turbine needs the oil emulsion that burns, but when in starting process etc., certain in particular cases needs to burn pure oil, electric control valve 2 cuts out, oil-water emulsifying device 5 does not work, and is closed by Electric Actuated Stop Valves 11, Electric Actuated Stop Valves 12 is opened.By controlling Electric Actuated Stop Valves 11 and the open and close of Electric Actuated Stop Valves 12, the conversion of oil emulsion and pure oil can be realized.
Beneficial effect of the present invention: system composition is simple, flexible configuration, easy to use, can realize Configuration Online oil emulsion, regulate in real time according to different operating mode, directly can be applied in various ground with in, marine gas turbine, have good market application foreground.
