Vesto +_ Switchgrass Pellets
Crispin Pemberton-Pigott, New Dawn Engineering, Roger Samson, REAP Canada, January 5,2008

Densified Canadian switchgrass pellets were burned in a VESTO (New Dawn Engineering) stove in the gasification mode.

Dear Grass Burners

Roger Samson was here today with Stephanie and he brought along a Mayon Turbo stove with rice husks and a big bag of switchgrass pellets.

We tried this 'fuel of the future' in the Vesto which first required putting a small sheet of newspaper at the bottom to keep the little pellets in, and second perforating the sheet to let in a least a small amount of primary air.

It was packed pretty tightly. The pellets are about 15 MJ per litre.

We lit it on top with a small wood fire and it got going nicely. It burned very much like a Vesto with the 'gasifier mode' engaged meaning that it ran with very little primary air getting through and a floating bed of flame perhaps 7 cm above the fuel. Very pretty.

The CO/CO2 ratio was stable at 2% and had no odour or visible smoke. I will get some picture posted and a movie with a description by Roger.

The flamefront was shallow, as Alex describes with wood pellets. Nothing really to add - it burned completely and gave off lots of heat.

Regards
Crispin

Stove Performance Report: Mayon Rice Hull Stove
Aprovecho research Center, July 18, 2005

INTRODUCTION:

This report serves to provide detailed performance measures of the smaller red model of the Mayon Turbo Rice Hull cooking stove including speed, fuel use, efficiency, and emissions produced. Stove performance is also considered in comparison to a laboratory open fire and the average of four similar wood burning stoves recently tested at the Aprovecho laboratory. Comments are included describing ease of use and recommendations for possible design improvement.

The Mayon Turbo stove reduces both Carbon Monoxide and Particulate Matter when compared to a carefully operated open fire. It is especially successful at reducing Particulate Matter.
