Abstract: A steam boiler includes a boiler housing. A helical coil for boiling water and superheating the wet steam is disposed within the boiler housing. A burner emits combustion gases which heat a heat emitter which is disposed in the inner space of the helical coil. Combustion gases from the burner enter the internal cavity of the heat emitter and then pass through perforations in the heat emitter before contacting the helical coil. As such, the heat emitter is heated by the combustion gases and serves as a radiant heat source for the helical coil.

Abstract: The invention relates to a combustion method which is performed in a furnace that is equipped with energy recovery means and burners, whereby the heat from the combustion fumes is recovered by energy recovery means and said recovered heat is used in order to heat the air. According to the invention, at least part of the burners performs the combustion of an oxygen-rich comburent and a fuel and at least part of the air heated by the energy recovery means is used to heat the oxygen-rich comburent and/or fuel for the burners.

Abstract: The invention relates to an arrangement for preparation of a fuel for combustion including a burner, a combustion chamber associated with the burner and in which combustion of a fuel is to take place in use of the arrangement as well as means for supplying liquid fuel to the arrangement through an internal passage in the burner for said combustion, solid portions of the burner body being heated by said combustion in use of the arrangement, wherein said internal passage is located inside said solid portions of the burner body for receiving heat energy evaporating said fuel from these body portions, and that it comprises means for conveying vaporized fuel to the combustion chamber to take part in the combustion.

Abstract: The present invention is an improved a combustor incorporating a pre-mix/pre-evaporation chamber arranged and configured to produce both a cool portion and a hot portion that cooperate to vaporize a liquid fuel to produce a lean to low-rich combustion mixture that is ejected from chamber into the combustor where is then ignited to produce a stable non-sooting flame maintained substantially within a combustion zone that yields a clean hot exhaust stream for heating downstream process components or processes such as one or more components of an autothermal reformer (ATR).

Abstract: A catalytic combustion device has a fuel supply means communicated with a fuel supply source, an air supply passage communicated with an air supply source, a premixing chamber for mixing together fuel supplied from the fuel supply means and combustion air supplied from the air supply passage to form a fuel-air mixture, a catalyst installed in a combustion chamber to cause oxidation reaction of the fuel-air mixture supplied thereto, thereby effecting catalytic combustion, and an exhaust passage for discharging combustion gas from the catalyst in the combustion chamber.

Abstract: A combustion chamber with an evaporator that projects into the combustion zone of the flame tube and includes a coaxial channel and to which air and fuel are supplied separately; a deflection surface is thereby arranged at the end of the evaporator channel which deflects the fuel/air mixture on all sides essentially opposite to the main flow direction prevailing in the channel; an annular channel partly surrounding the evaporator channel adjoins the deflection surface which is in communication by way of discharge openings with a mixing zone disposed upstream of the combustion zone, as viewed in the main flow direction; the mixing zone is formed by an annular space between an outer wall of the evaporator and an intermediate wall of the flame tube, in which are arranged radial webs within a first and a second plane, whereby the discharge openings of the annular channel terminate between the radial webs.
