December 1 reporter was informed that the global contracting Northeastern China Petrochemical Company to optimize the operation of vaporization decompression steam system to transform energy-saving projects, after electricity and power generation grid success.After testing, screw generator sets in the maximum and minimum intake load conditions, The parameters to meet the design requirements, 72-hour shipping work, the project successfully put into operation.
The project is the first unit in China that is applied to units with an inlet temperature above 400 degrees Celsius, an inlet pressure of 4 MPa and an inlet-outlet pressure differential of over 1.5 MPa. Under this condition, the installed capacity of generator sets The same for the country's largest project put into operation, a single set of screw expansion power plants can save 8,000 megawatts per year.
Screw expander generator set is just developed in recent years, the use of waste heat and pressure equipment, there is no precedent in this operating conditions. Global Northeast Engineering Company and external scientific research units to form a special project team, many discussions and amendments to system processes And the implementation of the program, and with 4 months to build a power of 1000 kilowatts of the largest domestic medium-pressure steam pressure generation test platform, has conducted more than 20 tests, to obtain a large number of test data and system optimization design to ensure the smooth progress of the project .
