摘要： PURPOSE:To improve the combustion property and the reliability of the combustor by a method wherein the flow amounts of primary and secondary air, introduced into a head combustion chamber and a rear combustion chamber, are controlled so as to meet the amounts of primary and secondary fuels to reduce NOx in exhaust gas and restrict generation of CO and unburnt constituent within the wide operating range of the gas turbine. CONSTITUTION:The secondary fuel 49 is injected from a plurality of fuel nozzles 40 toward a secondary air ports 39 opened at a plurality of places and is mixed with secondary air stream 30 to supply it into the rear combustion chamber 11 and form a premixed flame 43. The primary fuel 44 is introduced from a plurality of primary fuel nozzles 46 into the head combustion chamber 7 and forms diluted low-temperature combustion flame 48 under being mixed with the air stream 24 or conditioned primary air stream 47. Adjusting valves 33, 42 are operated so that the flow amount of the primary fuel 44 becomes a constant ratio to air by the change of load by a proportional operator 50 adjusting the ratio of fuel to air. On the other hand, the secondary fuel 49 is introduced with a flow amount meeting the reduced part of the primary fuel 44 and the adjusting valves 41, 32 are operated so that the ratio of fuel to air, in which it is within the range of combustion and not generating CO or unburnt constituents, is obtained.

CONSTITUTION:Air flowing into a sub-chamber 10 from a primary combustion air hole 22 and a secondary combustion air hole 23 and air flowing into a main chamber 11 through an air swirl vane 16 are separated, and controlled in response to the load of a combustion chamber. An annular air chamber 25 is separated into air chambers 2 by a parting plate 27 amounted to the inside of the chamber 25. An upstream side air chamber 28 represents an air chamber for supply to the sub-chamber 10, and a downstream side air chamber 29 is used as an air chamber for inflow into the main chamber through an air swirl vane 14. A cylindrical ring 32 movable in the axial direction of a liner is used as a method through which the quantity of air is controlled by closing or opening the air holes 28 or 29.

摘要： PURPOSE:To restrict occurrence of non-combustible part when second step fuel is fed and improve a stable combustion by a method wherein the second step fuel feeding of a specified amount is fed in a stepwise manner and at the same time a similar amount of fuel for the first step is reduced. CONSTITUTION:The first step fuel 200 is fed to from a circumferential wall of a cylindrical cone 3 so as to perform a rapid mixing with combustion air supplied from the circumferential wall of a sub-chamber 2 to perform a combustion of lean mixture of low temperature to establish a low NOx. A second NOx is established by a method wherein fuel 201 of second stage is supplied to the interior of the rotor 6 to make a premixing of fuel and air and a uniform low temperature combustion is realized. Feeding of the second stage fuel during increasing of the load of gas turbine is performed in a specified amount in a stepwise manner and at the same time the first stage combustion is performed under a stepwise subtraction. With this feeding step, an incomplete combustion stage caused by excessive lean combustion in second stage is immediately passed and moved to a stable combustion zone, an excessive increasing of the non- combustible is restricted and non-stable combustion is also eliminated. A ratio between the second stage fuel flow rate and the air volume of second stage combustion shows a preferable ignition and combustion in a range of 0.01-0.04.

摘要： PURPOSE:To obtain a premixing burner adapted to achieve an optimum burning from the viewpoint of NOx reduction, by effectively combining a multiple cylinder for realizing a compact construction in a burner having a long mixing flow passage. CONSTITUTION:Hollow portions 21, 18, 14 and 9 constituting a mixing chamber are concentrically formed in a multiple cylinder, and so a mixing flow passages can be made long with ease. In an embodiment shown, the mixing flow passage can be made about four times longer and as a result an air and a fuel experience a mixing procedure four times longer to facilitate their mixing very much. In addition, the mixing chamber has its hollow portions formed with reduced diameter in the direction of flow, thereby making it possible for the flow passage to progressively reduce its cross-sectional area with ease. Since an air-fuel mixture flows through the premixing burner with different speeds of V1>V2> V3>V4, further advantages in an efficient mixing and a back fire prevention can be obtained. In particular, an arrangement of combining several cylinders with different diameters in a concentric configuration provides a simplified construction which is advantageously easy to manufacture.

摘要： PURPOSE:To reduce NOX by injecting small amount of water by providing an inner cylinder formed of a premixture combustion chamber which has a combustion nozzle, a swirler and an air hole formed at the periphery and a water injection unit at the rear flow section and a rear combustion chamber in an outer cylinder. CONSTITUTION:An inner cylinder 29 formed of a premixture chamber 31 and a rear combustion chamber 32 of a diameter larger than that of the chamber 31 is provided in an outer cylinder 28. A fuel nozzle 36 is provided at the side inner end of the chamber 31, a swirler 33 and an air hole 34 are formed on the outer periphery, and a water injection nozzle 43 is provided at the rear flow section of the chamber 31. Fuel 24 introduced from the fuel nozzle 36 is mixed with air streams 25-27 from the swirler 33 and the air hole 34, and low temperature combustion is continued. Since NOX is produced due to main flame 42 in the step of burning, NOX reducing effect can be raised with less amount of water by performing the uniformly cooling of the flame with the water 44.
