Details of the software products used to create this PDF file can be found in the .. ISO was prepared by Technical Committee ISO/TC , Gas turbines. This International Standard applies to open-cycle gas-turbine power plants using combustion systems supplied with gaseous and/or liquid fuels as well as.

In the article, the test conditions are described and the test results are presented and analyzed. During the tests, 92 operating modes within a wide range of electrical loads and ambient air temperatures and operating conditions of the GTP when fired with fuel oil were investigated. In the tests, an authorized automated measuring system was applied. The switch to firing fuel oil results in a reduction in the turbine inlet temperature and the capacity of the GTP. Within the investigated range of power output, the emissions of nitrogen oxides do not exceed 35 ppm for the gas-fired plant and 65 ppm for the fuel-oil-fired plant. At low loads close to the no-load operation mode, the CO emissions drastically increase.

Furthermore the gas turbines used are often applicable to other markets, such as oil and gas, and marine, which reduces unit cost.

Aero-derivative gas turbines are the most common, though some heavyweight engines are used. Aero-derivatives usually employ the core from a large civil turbofan as a gas generator, with a custom designed free power turbine for industrial use. While this is not necessary for CHP applications, it is essential to also allow use in oil and gas and marine.

The aero-derivatives are at the top end of this range as this pressure ratio level results from a civil turbofan core. They are employed to satisfy the peak demand for electrical power which may occur on mid-weekday evenings as people return home and switch on a multitude of appliances. They serve the extra demand for electricity which is seasonal, such as the winter period in temperate climates where demand increases for domestic heating and lighting.

The considerations in selecting the type of powerplant for a base load power station are as follows. In all cases weight and volume are of secondary importance.

For base load plant, start and acceleration times are unimportant. Peak loppers are mostly simple cycle gas turbines burning either diesel or natural gas, and some diesel engines are used at the lower power end. This is because the unit cost and time onto load are far lower than for other available alternatives, which involve steam plant.

Both aero-derivative and heavyweight gas turbines are employed as peak loppers, either single spool or free power turbine, and with pressure ratios between 15 :1 and 25 Blade root stresses increase in proportion to AN 2 see Chapter 5. For nuclear power the case is complex, depending upon individual government policies and subsidies.

Engines currently in production are in the — K SOT range, and pressure ratios range from 13 :1 to 16 For a number of concept engines SOT levels of — K are under consideration, with pressure ratios of 19 :1 to 25 These employ advanced cycle features such as steam cooling of NGVs and blades. As indicated on Chart 1. Aero-derivative gas turbines are currently limited to around 50 MW due to the size of the largest aero engines.

In this power bracket they are competitive in combined cycle, particularly at higher SOT levels. Mid merit power stations employ simple cycle gas turbines of a higher technology level than those used for peak lopping.

Corresponding SOT levels are — K. Advantages of a closed, as opposed to open, cycle include the following. The use of energy sources unsuited to combustion within an open gas turbine cycle, such as nuclear reactors or alternative fuels such as wood and coal. However, few closed cycle plants have been manufactured despite numerous studies for power generation and submarine propulsion.

The high unit cost results from the plant complexity and the implications of designing for very high pressures. This industry also has the need for some local primary power generation and emergency power generation. The requirements here are as per section 1. Pipelines have diameters of typically mm 36 in to mm 56 in , and are usually underground.
