tail gas: off-gas from the regeneration process of the sorbent that is regenerated. This gas typically contains significant quantities of contaminants, such as H2S and SO2, and needs cleaning treatment prior to admission to the atmosphere.
test: single run or the combination of a series of runs for the purpose of determining performance characteristics. A test normally consists of two runs.
test reading: single recording of all required test instrumentation for the purpose of determining performance characteristics.
test run: group of test readings taken while the facility is operating at steady state at a specified operating condition.
thermal efficiency: ratio of the energy output to the energy supplied to the GCC facility, expressed as a percent.
tolerance: acceptable difference between the test result and its nominal or guaranteed value. Tolerances are contractual adjustments to test results or to guarantees and are not part of the Performance Test Codes.
topping cycle: higher temperature thermodynamic power cycle of a combined cycle system.
transmission dynamometer: device that measures the torque transmitted from one machine to another, without appreciably affecting the torque.
turbine: mechanical rotary component that produces work by action of the working fluid.
tuyeres: injection ports through which oxidant is fed into certain types of gasification vessels.
unbu med combustible: combustible portion of the fuel that is not completely oxidized.
uncertainty, random: numerical estimate of the random errors. It is usually quantified by the standard deviation of the mean for a set of test data.
uncertainty, systematic: numerical estimate of the systematic error.
uncertainty, test: test uncertainty combines random and systematic uncertainties.
volatile matter: portion of mass, except water vapor, that is driven off in a gaseous form when solid fuel is heated in accordance with the applicable ASTM standard.
working fluid: gas or liquid stream from which work is extracted, such as by powering a gas turbine.
3-1 INTRODUCTION
This Section provides guidance on the conduct of integrated gasification combined cycle (IGCC) plant testing, and outlines the steps required to plan, conduct, and evaluate a Code test of plant performance. The Code recognizes three different types of gasifiers: fixed bed, fluidized bed, and entrained flow, and their air-blown and oxygen-blown varieties. The methodology used in the Code can be used to test other gasifier designs.
Persons planning a test shall use Section 3 to define the test and secure agreements from all parties to the test, then use Section 5 to select the appropriate equations, then use Section 4 to select the instruments and methods of measurement needed to provide the values for the selected equations. The equations in Section 5 are used to calculate performance to support specific test goals, and to determine the uncertainty of the test results. Section 6 outlines the form of the final test report.
Regardless of the test goals or operating mode, the results of a Code test will be Corrected Net Power and either Corrected Heat Rate or Corrected Heat Input. The test must be designed with the appropriate goal in mind to ensure that proper procedures are developed, the appropriate operating mode during the test is followed, and the correct performance equations are applied.
