Installation of 03(Three) units of MWM TCG2020V16K gas generators is required to follow the guidelines recommended by MWM. This will ensure the smooth operation of the generator. The guideline points are as follows.1. Generator Room:
The generator room should be enclosed and dust-free.
Like other generators, you need a strong foundation bed to place a generator. For MWM please ensure that the generator foundation is complying with the MWM generator foundation loading data. As per MWM, the floor level should be ±2 mm. We are attaching the power plant layout along with the foundation loading data.
The control room should have a sufficient air cooling system so that the room can maintain a temperature below 25 ⁰C. This control room will contain GCP and MDB.3. Proper ventilation system with filtration system:
In practical operation, keeping the generator cool enough is a big challenge. The generator room should have proper ventilation with a filtration system and positive pressure around a 3-4 mm water column.
It is recommended to have at least 72,000 m3/h inlet and 47,000 m3/h outlet flow capacity ventilation for each of the MWM TCG2020V16K generators. Airflow direction needs to be from the alternator side to the engine side and ventilation ducting is required to through the inlet air in the proper position.
As per MWM, the generator room temperature should be between 25⁰C – 35⁰C to keep the operation smooth.
MWM’s recommendation is to use G3 class filters in the ventilation system to keep the room dust-free.4. Raw water circuit:
The cooling tower should be installed on the rooftop of the generator room and should have sufficient space for suction air. If your plant is located in a very dusty area then please keep a wire mesh fencing arrangement to reduce extra dust or water scale in the Heat Exchanger Plate and Colling Tower Enfill. Please find the attached cooling tower foundation drawing which is easy to install and will reduce foundation cost as well.5. Gas System:
MWM supplied gas regulator range is min 0.2 bar to max 4 bars. The flow requirement for each of the TCG2020V16K generators is approximately 391 m3/h (with 5% tolerance).
6. Installation of Electrical and Mechanical items needs to be as per MWM guidelines. At this time you should keep continuous communication with your assigned project engineer from MWM.Note: Your Plan, design, and Drawing can be different according to your location, purpose, and requirements. So, please consider talking with your assigned project engineer before any decision.
