What factors determine the consumption of 36 kilograms of steam, and how can this consumption be reduced? Thank you
It should be changed to 3. What factors affect the consumption of steam in 5Mpa turbines, and how can this consumption be reduced? vs 3. Related to the steam consumption of 5Mpa turbines: 1. Load requirements of the unit ； ⒉The back pressure or vacuum level of the unit ； ⒊Steam quality: Are pressure and temperature within the required ranges? Ways to reduce consumption: 1. Adjust the speed according to the process requirements, as long as those requirements are met and the compressor does not experience surge ； ⒉Back-pressure type requires that the pipeline network pressure must not exceed the specified limit ； For condensing types, every effort must be made to improve the vacuum level ； ⒊Requirement: The pressure in the 3.5 Mpa steam pipeline network should be 3.5 Mpa, with a tolerance of plus or minus 0. Fluctuations of 05 Mpa, with a temperature above 400 degrees.
Our temperature is over 340 degrees, and it sometimes needs to be lowered further. Back-pressure steam turbine.
One option is to increase the steam pressure under permissible conditions, for example to 3.6 MPa, or to raise the steam temperature; under the same conditions, the steam consumption will be reduced.
According to the requirements of the users for the steam being compressed, reducing the pressure of that steam – in other words, increasing the steam pressure difference – can also help to reduce steam consumption
For steam under such high pressure, should efforts be made to reduce local friction losses and leakage losses, as well as to ensure proper insulation?
1. Reduce the backpressure. 2. Increase the steam inlet pressure. 3. Raise the steam inlet temperature. 4. Reduce the unit’s operating speed if conditions permit (it’s convenient if a 505 is available)
Reducing steam consumption should not come at the expense of increasing auxiliary power consumption. If the vacuum level is too high, it may result in the benefits generated not being sufficient to offset the electrical energy consumed, which is uneconomical; therefore, the vacuum pressure should remain below the limit value
Backpressure compressor: 1\Increase superheat temperature 2\Reduce backpressure. Full condenser: 1\Increase superheat temperature 2\Reduce vacuum level
