New results of an innovative biomass gasifier

Traditional gasifiers are based on the engineering paradigm that gasification is linked to the lack of oxygen in the primary air flow. From a physics point of view, this paradigm cannot be understood: we therefore changed the approach, creating a gasifier that works in the presence of an abundant flow of air, which is wireable and very compact. We will describe improvements and new results of this device. With this gasifier it is possible to gasify even low-quality biofuels such as municipal green waste and even straw. The amount of unused biomass is enormous: a country like Italy typically produces 10 million tons of straw per year, and a medium-sized city produces around 20000 tons of greenery which must then be disposed of at considerable cost. The goal is to produce city gas with this device from rapidly growing waste" biomass, to replace fossil gas in all applications. The gasifier can process biomass even partially, producing gas and bio-char. Storing this bio-char is a simple and economical way to sequester carbon.
