Scope
GB/T 28686-2012 is the English-translated version of 燃气轮机热力性能试验.
GB/T 28686-2012 is the Chinese standard "Gas turbines thermodynamic performance tests". Its scope clause reads: This standard specifies the test methods for power, Heat Rate (thermal efficiency) and other major performance parameters of the gas turbine power generation unit.
The aim is to Determine thermal performance test results and revise the gas turbine under test conditions.
This standard applies to the fuel gas or liquid fuels (solid or before entering the gas turbine fuel into a gas or liquid fuel) burning Test gas turbine including with emission control and/or power increasing device (such as fluid injection and intake process) gas turbine test.
It can be adapted For a gas turbine combined cycle plant in the band or other heat recovery systems. This standard does not apply to gas turbines are being developed. Its clauses include definitions and symbols.
