On the industrial gas turbine from an instance of the development strategy


Several earlier in the same file modified gas turbine power advanced air compared to the low rate, simple knocking through the two-some, but the higher than combined cycle efficiency. Moreover,[link widoczny dla zalogowanych], according to information on the United l cycle operation, the part-load efficiency is very good, has been to maintain the 50% load. Row dare indicators 9l! I is unmatched by other units, even if the use of DLE combustion chamber LM6000, the N emissions, burning no gas and up to 25ppm ~, burning oil when the election 42ppm. . '2. Results dig layout (1) axis can be arranged by the two hydraulic Aunt pad bearing support, parts and components to a minimum, the reliability increases. (2) modular design, the combustion chamber when the spoon remove the engine to be decomposed. (3) The compressor is GT24/26 scaled down, a total of 15, the former three adjustable vanes, pressure ratio 2O: 1, compressor rotor using ABB's proven electron beam welding structure. (4) for the ring structure of the combustion chamber, a burner 30 AEV, AEV individually removable burner is ABB, GTlO and G. T ~ 5 of the EV burner further development of soul, which in; further reform the police and the air mixed with fuel rod, the load down to 5O, their emissions remain unchanged even if the low thousands 5OI} emissions will not significantly increased. As the number of multi-burner combustor exit temperature distribution more uniform, turbine blade life expectancy. (5) a total of three turbine first stage blades l 2 before using single crystal materials using advanced cooling technology. Turbine inlet temperature of 1207 ℃,[link widoczny dla zalogowanych], higher than the company's GT10 100 ℃, and LM6, and FT8 quite. . 000 (6) cold flounder hug output. Axial exhaust turbine side,[link widoczny dla zalogowanych], the advantage of high efficiency exhaust diffuser, and the use of cogeneration and combined cycle, l waste heat boiler is easy maintenance and inspection. (7) All accessories are arranged on the engine side, easy maintenance, easy to see that this structure is reshaping the layout and design of a solid structure of the traditional industrial gas turbines located pry modified gas turbine air No combination of advanced technology, outstanding reliability and maintainability. I think this is very commendable. Third, the low life cycle cost mentioned before. GTX100 gas turbines and air modified the focus of competition is the life-cycle costs. In assessing the power of the life cycle cost, the fuel and maintenance costs as appropriate for the main cable. Fuel prices, increased use of the relative importance of credit repair i} if fuel prices. More attention is the efficiency of the unit. According to the literature reports, the general rate of impaired drum 2 the first point, will increase the life cycle cost of about l5 50O million; maintenance costs. With changes in $ 1 / MW ・ h, will result in 15-year life cycle cost changes asked 4OO. n! million, in areas with low fuel prices, efficiency of simple cycle is equivalent to the difference of 4 percentage points. Overall, GTX100 with the same power level of the advanced gas turbine air modified compared to lower efficiency of simple cycle, combined cycle efficiency and higher, fuel costs can be considered significant (in fact, the United Cycle and Cogeneration station is the main Lou pull out line mode. GTX100 advantages). However, by simplifying the structure of the GTX100 and the use of modular design, highlighting the maintainability, thereby reducing downtime and can be as high as 96-97 is expected, so has the renovation of the advantages of low and high reliability based on analysis, if the operation of more than 120,000 hours. GTXIO0 the maintenance costs for the $ 1,350,000 / Mw ・ h, equivalent levels of air modified gas turbine of State for the $ 3,000,000 / Mw ・ h. Fourth, the commercialization process, the main developer and manufacturer GTXi00 Sweden ABBStal Sheng for the Secretary, and some are pieces of test (test crop of high-pressure chamber discretion in Moscow Russia. Whole experiment ended in 1997. In 1998 for construction of the market in the Nordic has been the installation of a reheat steam cycle with the use of seawater / river water recycling units directly associated cooling equipment the most. commissioning towel after the first 5 years 1 lO ~ l5 Ran planned production units,[link widoczny dla zalogowanych], 3 white ship ready in the summer of 1998.
