摘要： A boiler having a hot gas generator for burning liquid or gaseous fuels. The hot gas generator comprises a combustion chamber unit, into the combustion chamber of which the fuel and air for combustion are introduced and in which the combustion of the fuel takes place. The combustion gases are conveyed out of the combustion chamber into a water cooled boiler firebox. A compressor supplies the air for combustion into the combustion chamber unit. A flue gas conduit, which leads to the flue gas vent of the boiler, at its inlet end, which is connected with the boiler firebox, is connected with the air intake of the compressor of the hot gas generator for recirculating a regulatable amount of flue gases into the combustion chamber unit of the hot gas generator. The flue gas conduit offers a resistance to the flow of flue gas therein, which resistance is greater than the chimney draft force present in the flue gas vent of the boiler.

摘要： A method and an apparatus for performing combustion in a closed system employing recirculated exhaust gas, by the use of a combustion chamber and an exhaust gas cleaning chamber connected by an exhaust gas duct and a recirculation pipe to the combustion chamber. The exhaust gas cleaning chamber has an oxygen supply pipe, means for supplying a pressurized aqueous solution (or oxidant-absorbing pressurized aqueous solution), a carbon dioxide supplying means, and a mixing fan. A safety pressure valve is provided on said exhaust gas cleaning chamber for discharging excess exhaust gas that becomes present in this chamber to the outside of the apparatus. The oxygen supply pipe has an oxygen flow rate regulator. An oxygen content sensor is provided in the recirculation pipe leading from the cleaning chamber to the combustion chamber and this sensor is operably connected to the oxygen flow rate regulator. In this combustion method and apparatus, because the combustion chamber is closed, practically no oxidant constituents NO.sub.x or NO.sub.x plus SO.sub.x are discharged to the atmosphere, and the supply of oxygen in the recirculating exhaust gases is regulated to be about the same as that of air (about 21 vol.%). This method and apparatus can be applied to internal combustion engines as well as to external combustion devices, such as furnaces, boilers and the like.

摘要： The present invention relates to fluid heater apparatus having a firing wall, a back wall and side walls defining a furnace space. A plurality of fluid heating tubes are disposed in the furnace space and one or more high intensity combustion burners are attached to the firing wall and positioned so that combustion gases produced thereby are directed into the furnace space and caused to circulate around the heating tubes. By the present invention at least one baffle is disposed in the furnace space adjacent to the firing wall defining a secondary chamber in which additional heating tubes are disposed so that combustion gases impinge on the baffle after impinging on the back wall and are caused to recirculate around the heating tubes and then flow through the secondary chamber whereby additional heat is transferred to the fluid being heated.

摘要： Formation of nitrogen oxides and/or soot is obviated by mixing recycled combustion gas with incoming comburant supplied to a burner via a distribution opening and controlling the mass flow rate of combustion gas being recycled with respect to the mass flow rate necessary for the gaseous comburant, the mixture being passed to the burner as a turbulent flow in which the ratio between the kinetic momentum flux of the mixture and the product of the radius of the said distribution opening times the axial movement quantity flux of the mixture has a value at least sufficient so that the said turbulent flow produces a recirculation of the said mixture within the combustion chamber in the form of a toroidal vortex. This is achieved by apparatus comprising a mixing enclosure having two inlets each provided with means for regulating the size of its aperture, and an outlet, inlets communicating respectively with the atmosphere and with a duct for combustion gases, the outlet being connected to the inlet of a ventilator whose outlet communicates with gas mixture supply means arranged coaxially to a fuel injection nozzle in order to impart a turbulent motion to the gas mixture emitted from the supply means.

摘要： A modular boiler having a cylindrical combustion chamber made of three modules and a module comprising a cover and a module comprising an expansion vessel mounted coaxially on the boiler adjacent the combustion chamber at opposite ends thereof. The cover has a frustro-conical configuration with the inner walls thereof diverging from an opening in the cover toward the interior of the combustion chamber at an angle of between 30 DEG and 110 DEG . The combustion chamber is formed of three castings that define the cylindrical combustion chamber and six axial hot gas flow paths spaced circumferentially from each other and disposed axially of and radially of the combustion chamber. Hot gases from the downstream end of the combustion chamber are recirculated to the upstream end of the combustion chamber to improve the combustion. Hot gas is diverted from these hot gas flow paths and flowed spirally of these flow paths along axially spaced flow paths immersed in the water circuit of the boiler to improve heat transfer. Liquid fuel is fed into the combustion chamber from a burner at the opening of the cover. The fuel is mixed with air to which a rotation has been imparted about the axis of the arrangement and entering the opening of the cover. The cover is jacketed and the jacket defines part of the inlet cold water circuit and the heated hot water circuit.
