Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by China Electrical Equipment Industrial Association. The standard screw expander by the National Standardization Technical Committee (SAC/TC512) centralized. This standard drafting of the main unit. Jiangxi Huadian Power limited liability company. Participated in the drafting of this standard. Xi'an Thermal Power Research Institute Co., Ltd., Shanghai Power Equipment Research Institute, Shenzhen Energy Set Mission Moon Bay Gas Turbine Power Plant. The main drafters of this standard. Shi Yanzhou, Huda, Wang Xingping, Yu Yuefeng, Su Jian. Screw expander (group) performance acceptance testing procedures

1 Scope

This standard specifies the test methods for low temperature waste heat power generation or driving (group) and thermal performance with a back-pressure condensing steam screw expander and Calculation program. This standard specifies the test preparation, uniform rules implementation and evaluation, also contains details of the test conditions. This standard applies to two-phase working fluid as soda, saturated steam or superheated steam screw expander unit, and a non-water as the working fluid (such as a low boiling point Working fluid) twin screw expander cycle unit. If you have any complex or special cases, the manufacturer and the purchaser not covered by this standard should reach an appropriate agreement before signing the contract.
