GB/T 8117.4-2017 is the English-translated version of 汽轮机热力性能验收试验规程 第4部分：方法D 汽轮机及其热力循环简化性能试验.
GB/T 8117.4-2017 is the Chinese standard "Rules for steam turbine thermal acceptance test—Part 4: Method D—Simplified performance test rules for steam turbine and its thermal cycle".
Its scope clause reads: This part of GB/T 8117 applies to wide-area steam turbine performance test running in superheated steam zone or saturated steam zone, applicable Turbines for various types, capacity classes and uses.
This section is mainly used for turbine performance monitoring test can be used before and after the turbine overhaul test can also be used in accordance with the implementation of this section small Turbine's guaranteed value verification, but not for large-scale steam turbine thermal performance acceptance test.
This section includes all types of thermal performance test is as follows. a) The whole machine cycle thermal efficiency or heat rate; b) the maximum output or output under the specified conditions; c) steam consumption rate; d) cylinder efficiency; e) pressure and temperature characteristics; f) the relationship between power and steam flow; g) Flow capacity; h) Feedwater heater performance monitoring; i) Condenser Performance Monitoring (etc).
This section does not include an analysis of the uncertainty of steam quality measurements. The purpose of this section is to give simple and practical test methods with different accuracies to provide the required tests for performance monitoring and diagnosis result.
If you take some of the measures highlighted in this section can also be used to verify the manufacturer's warranty value. Its clauses include scope and purpose.

This part of GB/T 8117 applies to wide-area steam turbine performance test running in superheated steam zone or saturated steam zone, applicable
Turbines for various types, capacity classes and uses.
This section is mainly used for turbine performance monitoring test can be used before and after the turbine overhaul test can also be used in accordance with the implementation of this section small
Turbine's guaranteed value verification, but not for large-scale steam turbine thermal performance acceptance test.
This section includes all types of thermal performance test is as follows.
a) The whole machine cycle thermal efficiency or heat rate;
b) the maximum output or output under the specified conditions;
c) steam consumption rate;
d) cylinder efficiency;
e) pressure and temperature characteristics;
f) the relationship between power and steam flow;
g) Flow capacity;
h) Feedwater heater performance monitoring;
i) Condenser Performance Monitoring (etc).
This section does not include an analysis of the uncertainty of steam quality measurements.
1.2 purpose
The purpose of this section is to give simple and practical test methods with different accuracies to provide the required tests for performance monitoring and diagnosis result.
