Which type of foundation is used for generator?
This Manual of Practice addresses the design of three types of concrete foundations for turbine generators: block foundations, with pedestals, piers, and blocks supported on a common mat foundation (basemat); elevated space-frame pedestal foundations, with columns, walls, and a tabletop supported on the basemat; and …
Can DG set be placed in basement?
The order of priority for the installation of gensets should be the basement followed by the rooftop, ground floor and the front or back side of the building. However, there should be no public inconvenience of any sort.
Do generators need to be on concrete?
Installing on the ground is the quickest, but to keep an expensive generator working correctly (not to mention within code and under warranty) it needs to sit up and out of the dirt and mud. Usually people fix this by putting down a bed of gravel and setting the generator on top of it. Ground, gravel or concrete.
What should be the stack height of DG set?
These standards are applicable to all the gensets that are manufactured and installed in India….Standard Stack Height For Diesel Generator (DG) Sets As Per CPCB Norms.
| For Generator Sets | Total Height of stack in meter |
|---|---|
| 200-250 KVA | Ht. of the building + 3.5 meter |
| 250-300 KVA | Ht. of the building + 3.5 meter |
Which type foundation is used for high speed machine like generator?
Machine foundations are used to help in the distribution of the machine loads and mitigate the vibrations developed due to the rotating machine parts. Turbo-generator foundations also known as framed-type machine foundations are the common supporting system for rotary machines of medium to high-speed [1, 2].
What are types of machine foundation?
Following are the types of machine foundations generally used:
- Block Type Machine Foundation: Following figure shows block type machine foundation.
- 2. Box or Caisson Type Machine Foundation:
- Wall Type Machine Foundation:
- Framed Type Machine Foundation:
- Non-Rigid or Flexible type of Machine Foundation.
Can generator be kept in Terrace?
“The diesel generator installed on the terrace is in direct violation of provisions of the National Building Code of India,” the order states. It directs that the genset be immediately shifted to the ground floor or basement, so that it does not pose a risk to structural safety of the building.
Why is earthing required for a generator?
1. Generator earthing. The neutral point of a generator is usually earthed to facilitate protection of the stator winding and associated system. Earthing also prevents damaging transient overvoltages in the event of an arcing earth fault or ferroresonance.
How far from the house should a generator be placed?
Always place the generator at least 20 feet from the house with the engine exhaust directed away from windows and doors.
What is the limit of PM emission for stack monitoring?
150 mg/Nm3
What is The Limit of PM Emission For Stack Monitoring? As per CPCB or Indian standards for Industrial Stack Monitoring the flue gas emission from boiler stack, DG set emissions, the furnace should not exceed the limit for Particulate matter beyond 150 mg/Nm3. However, this limit can vary depending on the industry type.
How do you calculate stack height?
- SULPHURIC ACID PLANT.
- Stack Height Calculation.
- Height (as per CPCB norms) = 14Q(E+0.3) = 14 x 385(E+0.3) = 14 x 5.97 = 83.5 metres.
- If emission factor of 1 kg/T were to be considered for stack height design.
- Height = 14Q(E+0.3) = 14 x 192.5(E+0.3) = 14 x 4.85 = 67.8 metres.
What is the standard size of a DG set?
Standard Size of The DG sets KVA KVA KVA KVA KVA 7.5 KVA 20KVA 35 KVA 62.5 KVA 100 KVA 10 KVA 25 KVA 40 KVA 75 KVA 125 KVA 15 KVA 30 KVA 50 KVA 82.5 KVA 200 KVA
What should the foundation height of a DG Set be?
The DG set shall be provided with proper exhaust muffler with insertion loss of minimum 25 dB (A). The length and breadth of foundation should be at least 250 mm more on all sides than the size of the enclosure. 300 mm of this foundation height should be above the ground level.
What should be included in a generator set Foundation?
Convenience and serviceability can be designed into a generator set foundation. Consider specifying conduit for electric starting systems, generator leads and fuel and water connections. No isolation is required to protect a generator set from self-induced vibrations.
Can you have more than one DG Set in a room?
In case there are more than one DG Set in one location, independent two nos. neutral earthing shall be provided for each DG set. However, two nos. earthing sets shall be common for the body earthing of DG Sets Open DG set in room. Min 1.5 times of the Radiator area. Min 2.5 times of the Radiator area. Min 1.5m between two foundations.
