I can't mention names but I wanted the TLUD community and stovers in general to be aware that one of the submissions is more than interesting. </font></div><div><font face="Calibri, Slate Pro, sans-serif, sans-serif"><br></font></div><div><font face="Calibri, Slate Pro, sans-serif, sans-serif">It is a TLUD charcoal maker that tested three times with a PM emission for the Central Java combination cooking cycle (the Technical Test) of just 2 mg/MJ delivered. This is about 1/4 of the PM from an LPG stove (as tested in India) and 1/10th of the emissions of a Philips fan stove burning pellets. Being somewhat suspicious because the test results could be accidentally that low three times in a row, it was repeated with great care to see nothing could possibly interfere with the result and the 4th test was substantially the same as the first three, except for a lower CO value <1 g/MJ delivered into the pot. </font></div><div><font face="Calibri, Slate Pro, sans-serif, sans-serif"><br></font></div><div><font face="Calibri, Slate Pro, sans-serif, sans-serif">The system efficiency is in the high 30's. The test method assumes char produced cannot be reused (see the test method online). The energy efficiency is much higher. </font></div><div><font face="Calibri, Slate Pro, sans-serif, sans-serif"><br></font></div><div><font face="Calibri, Slate Pro, sans-serif, sans-serif">This small, inexpensive natural draft product shows that solid fuels (Albasia pellets with 5.6% moisture in this case) can burn cleaner than LPG and natural gas if the fuel is predictable and standardised. </font></div><div><font face="Calibri, Slate Pro, sans-serif, sans-serif"><br></font></div><div><font face="Calibri, Slate Pro, sans-serif, sans-serif">The cost of standardising sustainable wood pellets is much less than the cost of introducing LPG, electricity or other liquid fuels. The result should of course be confirmed in other labs because it is running on the limits of detection and quantification wherever it is tested. If these results can be confirmed it throws down the gauntlet to the producers of other stoves that burn ethanol, DME, methanol and LPG to improve their product performance to match both this wood pellet burner and the very clean lignite burning stoves in Mongolia. </font></div><div><font face="Calibri, Slate Pro, sans-serif, sans-serif"><br></font></div><div><font face="Calibri, Slate Pro, sans-serif, sans-serif">Let's give them a round of applause in Ghana when the product is identified. I will try to obtain one this week to bring to Accra. </font></div><div><font face="Calibri, Slate Pro, sans-serif, sans-serif"><br></font></div><div><font face="Calibri, Slate Pro, sans-serif, sans-serif">Best regards </font></div><div><font face="Calibri, Slate Pro, sans-serif, sans-serif">Crispin </font></div></body></html>
