Abstract: The invention relates to a device and a method for biomass combustion and simultaneous CO2 capture for capturing the CO2 generated in said combustion to generate a substantially pure CO2 stream (9) which can be subsequently stored. The device comprises a combustor-carbonator reactor (a) which is fed with biomass and air; at least one solids recycling cyclone (b, c) which separates solids (5) returning to the combustor-carbonator and from which there exits a solids and gases stream (4). The device comprises a calciner B which regenerates CaO, a fluidized bed (d) and means for feeding fresh CaCO3 (12) and for purging solids (11).

Abstract: A commercial gas oven has as its only source of heat for heating and for steam generating an extended mesh-type burner and a sealed combustion chamber. The oven works in five cooking modes reaching steam saturation below 100.degree. C. and a high humidity up to 250.degree. C., combining air convection from a central turbine and the steam which is generated into the oven. At least one steam generator duct conveys the combustion fumes around a central turbine on whose surface falls the water sprayed from a sprayer linked to the turbine. The fumes are recovered to contribute to heating the cooking chamber by means of a takeup box.
