Måling av bekymringsfull høy produksjon av kullos (CO) ved bruk av en kjele med varmeveksler av typen Primus EtaPower

Carbon monoxide production from the PRIMUS EtaPowerTM Pot (1.7L) used on two different small commercially available camping stoves brands was examined (Optimus and Coleman). This pot was examined both at high and low power level. The carbon monoxide production from the pot used on Optimus 111 at high power level was about 450 ml/min. The corresponding value for Coleman Multifuel modell 550 was between 1300 and 2000 ml/min. This is 10 and 20 times increase in production compared to using an ordinary flat-bottomed pot, for the Optimus and Coleman respectively. Our measurements give reason for warning against the use of this pot (Primus EtaPowerTM) for cooking inside tents or within similar enclosed area. In particular it is advised against cooking continuously over extended periods of time.
