[Stoves] Can anyone identify the manufacturer of this stove?

Dear Dr Ramen

How nice to hear from you!  There must be some testing results available for this product (or set of products?) perhaps with power, PM and CO levels.

I noticed that a search for modern Indian kerosene stoves gives quite a number of products all of which claim a thermal efficiency of 60%. I wonder how the power v.s. efficiency curve looks.

It might surprise readers to discover that kerosene is still listed by organisations such as the WHO and CCA, CCAC and a variety air pollution control agencies list kerosene (paraffin) as "a dirty fuel" that should be removed from the domestic fuel market altogether. As far as I can determine, this call was first issued by Kirk Smith in 1999. Perhaps someone can confirm or correct this point.

Apart from bring an assault on the poor, the attribution of "dirty' to a fuel is also an assault on logic. The quality of burn is dictated by the combusting device. Most aircraft engines run on kerosene.

With all the interest in stoves meeting "Tier 5" on the ISO's technical report which promotes the concept of tiers and offers some default values, it is worth having a look at the performance of the modern products.

The Indian kerosene stove standard covering pressure stoves can be used as an example of a "specification standard" where every aspect of the permitted design is fixed. The modern stoves in the photos are wick stoves and are three times as efficient as the "old ones". Surely there are much better combustors as well? What is the performance?

I found some examples of LPG Stove emission factors from India of about 8 mg/MJnet which is Tier 4 for PM2.5. Are these modern kerosene stoves in that range?  Sixty per cent efficiency is Tier 5.  Are there Tier 5 Indian wick stoves?

And further, Dr Ramen (sorry to impose) what is the standard covering this class of products?  Are you also using IS-13152 for wick stoves?

There is a new methanol stove standard under development in South Africa. The stoves demonstrated have very low PM emissions. These and the ethanol stoves like the Koko are giving LPG good competition at the top of the market.

Dear Mr. Crispin,
There are some details available at: https://www.exportersindia.com/your-engineering-4186620/wick-stove-3795196.htm<https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.exportersindia.com%2Fyour-engineering-4186620%2Fwick-stove-3795196.htm&data=02%7C01%7C%7C03b935b350854787bc3108d825625260%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637300451502594759&sdata=UWq9%2BWIRa1GSwpPB0%2B6y1ABASDIVD76t20P7IEbZAxE%3D&reserved=0>
When we search with the keywords of “Nutan kerosene stove “ So many images appears.
It seems that the stove is still available in the market. This is one of the best stoves .
Best regards,
Dr. P Raman

My goodness, well spotted.

It looks as if it has more components than a Panda or similar.  The wick is a C-shape, correct?

Can I get a photo of one from somewhere?

This was spotted in Kinshasa, DRC. Is it possible they are still for sale?

Thanks
Crispin

This looks like an old Nutan Stove developed in early 1960s by Indian Institute of Petroleum and was manufactured by various companies in India. Before LPG came this was the most popular stove in India.

This is a wick-type kerosene stove with several features, none common.  It is not a bottom of the line product.  There is a little of the label still visible, and the pot rest is distinctive.

An ideas?  A Google photo matching effort failed to find anything even similar.

Thanks
