Emissions from In-Situ Diesel Generator Sets !!

[Sarath Guttikunda]

Dear All,

I come from an air pollution background and my question today, related to generator sets, is limited to emissions from them. Though the problem is much bigger than that.

Here is a case study from Gurgaon, once a satellite city of Delhi and now part of the National Capital Region of Delhi - "A booming suburb of New Delhi has become the symbol for development in India. It seems to have everything, except a functioning citywide sewer, reliable electricity or water, or decent roads."

From the New York Times, June 8th, 2011
http://www.nytimes.com/2011/06/09/world/asia/09gurgaon.html

"To compensate for electricity blackouts, Gurgaon’s companies and real estate developers operate massive diesel generators capable of powering small towns. No water? Drill private borewells. No public transportation? Companies employ hundreds of private buses and taxis. Worried about crime? Gurgaon has almost four times as many private security guards as police officers"

Besides the power bill from the grid, the CWG venues also used 24 DG sets, of 82.5 KVA capacity each at the stadiums for broadcasting sport events as well as other requirements.

*******

We have established urban emissions inventories (PM, SO2, NOx, CO, and VOC) for some cities in India - the sources are all the same, so we extend the courtesy to CO2 as well. Cities include - Delhi (much of this work is currently in use for the day to day forecasting of air quality in NCR - http://www.urbanemissions.info/daqi), Chennai, Ahmedabad, Indore, Surat, Pune, and Hyderabad.

One source we find very uncertain and underestimated (most of the times) is generator sets. We made some calls to big hotels, malls, hospitals, institutions and apartments, (especially in the Gurgaon and NOIDA sectors) and some markets, to get a sense of how much diesel is consumed in this sector and we calculate the related emissions. The five sectors mentioned above tend to be major operators of in-situ generator sets. Our estimated percentage contribution of generator sets to the PM emissions in the seven cities varied from 5-12% of the annual load.

Question -

Any of you ever talked about or discussed or saw some reports on
1. diesel usage in generator sets
2. average emission rates (any measurement data, especially for non-CO2 pollutants)

Looking forward to hearing from you all.

With regards,
Sarath

Dear All, 

Dr. Sarath Guttikunda is looking for information on... 

a) diesel consumption 

b) emissions from Particulate Matter (PM) and other pollutants 

from Diesel Generation sets in India.

His original query is included below. If any of you know of a paper or source of this data, please write.

Thanks,

Manu

Dear Manu,

Thank you TK.

Are these measurements from a lab or estimates from manufacturers?

With regards,
Sarath

Fantastic. Are these collected by your company directly? 

Thanks for sharing. I'm sure it will be extremely useful.

They are actual measurement carried out on site, data may vary depending on the age of the DG. You can verify that with specs from DG manufacturer.

Thanks Tk. I'm grateful that you shared this data with Green-India. 

Best,

Manu,

I got it from someone who works in a telecom tower company. 

The figures are quite realistic, maybe the rest can verify it as well.

i am attaching a datasheet shared by my friend at Research and development centre of one prominent DG Manufacturer.i have had requested for that data to calculate Waste heat recovery potential

so apart from sfc it also has some additional info.the sfc data can be compared with oine obtained from TK

will pass on emissions info if my friend obliges

Dear TK,

The data you shared can't be applicable for all the gensets, it's different in different Engine Makes. now a days EURO-4 Machines are there, 4 Valve Engines, CRDI Technology Engines are there in different makes and different ratings... which are differnet in performance,Efficiency fuel Consumption, BHP of the Engine...so it can't be considered for all the Machines. the data sheet which you have provided will be applicable only for One Make Engines.

Regards,

Manjunath
