Kramatorsk heat station
Frequently on heat stations the heat control is carried out using old well-known orifice method. Is it really good today?
Let's give an example of real money saving on Kramatorsk heat station due to replacement of orifices with ultrasonic meters SVТU-10М of accuracy class 1
Expenses | With orifice, ukr. hrivnas | With SVTU-10М1, ukr. hrivnas | Comments |
Equipment | 30000 | 50000 | The cost of orifice flow measuring set includes the cost of chamber, orifice, sensor of variable pressure drop, pulse tubes with valves, two temperature sensors, project and calculations of flow measuring section, its certification in State Standard Committee |
Installation and commissioning | 20000 | 20000 |
|
Annual service | 12000 | - |
|
Recording | 1000 | - | For 2 recorders |
Periodic calibration | 700 | 100 | Periodic calibration for SVTU-10М1 - 1 time in 4 years without dismantling. |
State verification | 10000 | 100 | Expenses on installation and dismantling |
Total expenses on installation and equipment cost | 50000 | 70000 | The difference in expenses is 20000 ukr. hrivnas |
Total expenses on annual operation | 23700 | 200 | SVTU-10М undergoes state verification 1 time in 4 years |
Mentioned in the table cost of the complete set of SVTU really exceeds cost of the complete set of orifices, but total expenses for maintenance service and periodic calibration considerably below. For a year the difference makes 23500 ukr. hrivnas. It means that initially it has been spent 20000 ukr. hrivnas more, but every year it is saved 23500 ukr. hrivnas for operation
Hence, expenses will pay back less than 1 year. As a result of application of new technical equipment the economy of the energy carrier has led to 14 %. It has paid back expenses for installation of new devices for one month! By the way the expenses for repair of registering devices (recorders) are not considered
