Crispin -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Frank Shields Sent: October-12-11 4:31 PM To: 'Discussion of biomass cooking stoves' Subject: Re: [Stoves] burning rice husk / IR measurements Dear Crispin, >From what I have read from people on this list; It seems the IR does not actually measure temperature (like expanding mercury) but interprets UV waves(?) coming off an object. Different colors and texture can change those waves so the instrument must be adjusted to estimate the real temperature of the object / surface the waves are coming off. In a box of constant temperature everything in that box is at that temperature. If the readings differ depending on color-texture we should be able to adjust the IR detector to the right temperature. Then next time we have the IR adjustment set to that surface and we can measure the temperature without the accurate bi-metal thermocouple in place. Is that how you look at it? I purchased the IR detector you suggested. I like that it comes with a probe reading also. But adjusting the IR reading with emissivity dial to match the probe is difficult. Perhaps because when the door is open one must be fast! I was going to have several pipes that I use for reading temperature. They were planned to have a surface area I would always point the gun at. Now I am thinking I will have a hole in one pipe for a probe inserted. I prefer pointing the gun at it so I could look at different places. I worry the side or front-back will have different temperatures with venting etc. Thanks Frank Frank Shields Control Laboratories, Inc. 42 Hangar Way Watsonville, CA 95076 (831) 724-5422 tel (831) 724-3188 fax [email protected] www.compostlab.com -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Crispin Pemberton-Pigott Sent: Wednesday, October 12, 2011 12:45 PM To: 'Discussion of biomass cooking stoves' Subject: Re: [Stoves] burning rice husk Dear Frank I am not forgetting your unanswered question about the actual temperature of your little pipe if the emissivity is different. Just trying to get time to be sure I give you the right answer. Regards Crispin +++++++ Stovers, I was talking to a rice grower in Northern Calif. and found out that Wild Rice has much less silica in the hulls than White Rice. I haven't tested wild rice hulls to confirm.

Regards Crispin +++++++ I do not know whether a stove can efficiently burn rice husk. But it seems rice husk can be burnt efficiently in FBC ( fluidised bed combustion ) boilers. There are several medium sized FBC boilers operated all over India. So the fuel need not go waste.
