Description
Technical field
The present invention relates to a kind of nozzle technology of heavy combustion engine.
Background technology
The nozzle of installing on the gas-turbine combustion chamber at present is generally many fuel nozzles.The nozzle of gas-turbine combustion chamber and burner inner liner are installed and are mainly contained two kinds of versions; A kind of is the corresponding fuel nozzle more than of a burner inner liner, and the nozzle arrangements of this kind version is simple, and is easy to installation and maintenance; But owing to have only a nozzle; Fuel concentrates on the burner inner liner central area, and flame is longer relatively, combustor exit temperature field inferior quality.When using the liquid fuel work of backup, the liquid fuel adjusting range is narrower.When the combustion chamber used liquid fuel under running on the lower load, to work, because fuel flow rate is less, charge oil pressure was lower, and the atomizing effect of centrifugal pressure atomized fog jet is not good, made the efficiency of combustion of combustion chamber descend even the flame-out phenomenon of generation.Another kind is that gas turbine burner inner liner head changes the structure that links to each other with a plurality of fuel nozzles into from the structure that an original fuel nozzle links to each other; Substitute single fuel nozzle system with many fuel nozzle systems; Can reduce combustion noise (dynamic pressure) level; Thereby reduce the wearing and tearing of combustion system, extended to 12000 hours to the inspection intervals phase of combustion system from 3000 hours.Adopt many fuel nozzles structure in addition, fuel is evenly distributed in burner inner liner, helps shortening the length of flame, improves combustor exit temperature field quality.When using the liquid fuel work of backup, through taking measure such as nozzles fuel supplying, i.e. during running on the lower load work; Have only portion nozzle participation work, can under the constant situation of fuel total supply, improve charge oil pressure like this; Improve the atomizing effect of fluid injector; Improve combustion chambers burn efficient, improve the combustion chamber extinguishment characteristics, effectively overcome one-jet deficiency.
Because the flame temperature in the gas-turbine combustion chamber has at high temperature produced the nitrogen oxide of some than higher, generally can reach 200 * 10
-6About, surpassed the environmental regulations of many industrialized countries.The engine chamber nitrogen oxide discharge capacity of early stage low loop parameter is not serious; But requirement along with engine booster ratio and turbine inlet temperature raising; The early stage measure that reduces carbon monoxide and hydrocarbon has not proved effective to reducing discharging, and the discharged nitrous oxides problem is outstanding.Combustion zone to the combustion chamber is injected water or steam according to a certain percentage; Can reduce maximum combustion temperature, suppress the generation of nitrogen oxide effectively, but because existing nozzle does not generally inject water to the combustion zone; Therefore need miscellaneous equipment to inject water to the combustion zone, method is loaded down with trivial details.
