Design and fabrication of eco-friendly, efficient and low-cost hybrid cookstoves; whith use of hidrogen fuel gas

Abstract

The generation of waste organic solids and residual water of industrial process with discharges loads polIn the present paper, the design of an efficient, ecological and low cost stove was carried out, with the novelty of using hydrogen as fuel gas, from its obtaining in electrolytic separation cells from water, applying the Solidword software, to give an answer, firstly, to the cooking of food as an alternative to the supply of liquefied petroleum gas, kerosene and to the saving of electricity, given the blockade conditions imposed by the North American administration; secondly, to the sanitation of waste from carpentry shops and other places in the city of Holguin; and thirdly, to provide a solution to another environmental problem, the accumulation of sargassum on the country's beaches, with a high level of heavy metals and arsenic, which affects these tourist environments. This biomass could be converted into briquettes, with a high calorific value and could be an option to help families living near the coasts and with low income, taking into account that in addition, the stove would save 50% of what is used in conventional wood stoves. On the other hand, sawdust and paper briquettes could be used as a result of solid waste from companies. Another variant of this stove that makes it hybrid, is when it is designed with two burners: one would work with solid biomass and the other with biogas, or hydrogen, or both fuels together. It should also be noted that it is not only a solution for homes, but also for military units, both at fixed points and on maneuvers, as well as for companies, schools, boarding schools, children's circles and public health units. A circuit in two variants for the use of hydrogen as fuel gas is detailed, as well as the design characteristics of its parts and components.
