Estudio experimental de la combustión de la cascarilla de arroz en una cámara de lecho fijo

Abstract

This paper shows an experimental study of the combustion of rice husk, based on an estimation of the energy density, based on a field study in the cities of Quevedo and Ventanas. The gross calorific value is determinate, and its moisture content according to the UNE-EN 14774. It was establish that rice husk must enter to the combustion chamber of fixed bed with humidity below 15% to reduce CO emissions, ash and soot. 14 kg/h of rice husk was burn and it was obtain 34.01 kW thermal per hour exceeding 650 °C temperature. Each rice husk particle remained burning during 4 seconds on average.
