re.:

What is the efficiency of UV lamp in ozone generation (Ozone g vs. energy consumed )

I read a lot of papers from the Internet on using UV lamp for generating ozone but none discussed the efficiency of such process.

How much energy (kWh) gets consumed by UV lamp to generate 1g of ozone ?

and related web links and all I get as pros and cons is:

" Ozone production from UV light for commercial applications Advantages of UV Ozone Generator

Simple Construction – only a UV lamp with ballast and a fan

Low cost – due to simple construction

Lower nitric oxide production


Low ozone output – g/hr

Low ozone concentration – less than 1% by weight

Bulbs and ballasts will need to be replaced


"

• "How much energy (kWh) gets consumed by UV lamp to generate 1g/h of ozone ?" I think you can spot the problem with this question yourself. Do you? – Karl Apr 28 '20 at 19:10
• I have asked alike question in Physics and was asked it to ask in Chemistry to get the correct answer – a a Apr 28 '20 at 19:14
• Either g per kWh, either g/h per kW. Not g/h per kWh. – Poutnik Apr 28 '20 at 19:21
• OK, two problems. ;-) The other is that UV light sources have their own efficency. Electricity -> UV photons (of what wavelength?) -> ozone – Karl Apr 28 '20 at 19:28
• I read about UV light source efficiency from one boomarked site but just visit UV Light Ozone Generators boie.us/uv-ultraviolet.php claiming ozone output: 10g/h and still no data on power consumed in the specification "Lamps: Long-life VH** 9,000-hour high-output ozone lamps not rated "Electrical Rating: 120V~60Hz 2.6 Amps So in theory, power consumed is less than 120V x 2.6 Amps = 312W. Hard to believe, low efficiency UV lamps can generate 10g/h ozone comsuming less than 1,000W x hr – a a Apr 28 '20 at 20:11
