[Stoves] Improving Thermal Efficiency (TARP-VE)

[Alex English]

Hi Dean,
So this begs two questions;
1.  How does a cook 'tune' the TLUD?

I would assume that tuning means adjusting air settings for levels of 
excess air and perhaps some mixing optimization.
With processed solid fuels, 'tuning' can  approach the same combustion 
quality territory as  liquid fuels. I can envision an engineer 'tuning' 
the design for a given homogeneous fuel, and a cook operating the TLUD 
stove according to a manual of instruction. However TLUDs are being 
promoted for use with a variety of fuels for which tuning may imply a 
fairly wide band, with more excess air.

Even with wood pellet fuel I could get variable deposits ( from near 
zero to significant) on PM filters while exit gasses still looked clear 
and smoke free. Excess air and there for peak mix temperatures seemed to 
correlate well with the filter deposits.

I look forward to seeing the full range of data for TLUD PM with a range 
of air settings, including during 'data blind' cooking tests where the 
operator has the average users level of instrumentation.

2.  What fuel specifications are required to get TLUD to operate 
consistently in the field at Tier 4 emissions levels?

Staying tuned,
Alex

  When you use a clean stove, like a tuned TLUD, the filter stays white 
after boiling and simmering the water.
