Download the full report Stove Performance Report: Mayon Rice Hull Stove

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.

RESULTS AT A GLANCE:

The chart below includes the average results of two full emissions tests and one simmer retest of the smaller red model of the Mayon Rice Hull stove:
