Tambien son conocidas las calderas que disponen de una camara de combustion para la introduction de combustibles solidos, tales como lena, carbon o similares, y de un intercambiador para el calentamiento del agua circulante de un circuito de calefaccion.Also known are boilers that have a combustion chamber for the introduction of solid fuels, such as fuelwood, coal or the like, and an exchanger for heating the circulating water of a heating circuit.
Estas calderas permiten consumir combustibles producidos especlficamente con este fin, por ejemplo madera procedente de explotaciones de madera, con tala controlada, pero presentan unas limitaciones lo que se refiere al limitado poder calorlfico que se puede alcanzar en la camara de combustion, lo que impide un aprovechamiento adecuado del combustible y a la elevada temperatura a la que son liberados los gases y humos a la atmosfera.These boilers make it possible to consume fuels produced specifically for this purpose, for example wood from wood farms, with controlled logging, but they have limitations regarding the limited calorific value that can be achieved in the combustion chamber, which prevents adequate use of fuel and the high temperature at which gases and fumes are released into the atmosphere.
El problema tecnico que se plantea es el desarrollo de un horno calefactor que quemar completamente aquellos combustibles solidos que no son estandar por su forma y tambien combustible solido troceado o desmenuzado, alcanzar un rendimiento elevado y evitar la liberation al exterior de gases a una temperatura superior a los 200°C.The technical problem that arises is the development of a heating furnace that completely burns those solid fuels that are not standard for their shape and also chopped or crumbled solid fuel, achieve high performance and avoid the release of gases at a higher temperature outside at 200 ° C.
Descripcion de la invencion.Description of the invention.
