20090107421 | Gasification boiler for solid fuels, in particular for bales of straw, with optimised exhaust gas values - The invention relates to a gasification boiler for the combustion of solid fuels, in particular bales of straw, for heating purposes and for the production of hot water. The inventive boiler is characterised by optimal combustion and ash separation. The aim of the invention is to carry out the combustion of small particles in the most complete manner possible and to achieve an almost total separation of the ashes from the combustion gas upstream of the heat exchangers. To achieve this, according to the first feature of claim 1, the combustion and gasification chamber comprises lateral depressions that are configured next to the central grating and combustion chamber. Coarse particles collect in said depressions, leaving the fine particles to be carried with the combustion gas into the combustion chamber. According to the second feature of said claim, a cylindrical combustion chamber, configured as an additional component, is connected to the outlet of the combustion chamber. Said secondary combustion chamber significantly increases the combustion time, allowing small particles and partially oxidised gases to burn completely. According to the third feature, a cylindrical ash separator, configured as an additional component, is connected to the combustion chamber. | 04-30-2009 |
20090183693 | High efficiency wood or biomass boiler - A boiler comprising a water jacket surrounding upper and lower combustion chambers for receiving heat for heating water or other fluid therein. The upper and lower combustion chambers are defined by a refractory structure which extends entirely across the inner casing. A vertical passage through the refractory structure provides for flow of combustion gases from the upper to lower combustion chamber. Oxygen is provided through a first forced air inlet to the upper combustion chamber for burning of wood or biomass in the upper combustion chamber. Oxygen is provided through a forced air passage in the refractory structure and opening into the vertical passage thereby providing at cast one second forced air inlet to the vertical passage for burning of the combustion gases and particulates passing therethrough from the upper combustion chamber. The refractory structure sealingly engages the inner casing in a manner to seal the upper combustion chamber from the lower combustion chamber so that the upper combustion chamber can be made substantially air tight whereby the upper combustion chamber can be pressurized by forced air thereto to effect expulsion of combustion gases and particulates from the upper combustion chamber through the vertical passage for burning thereof. Refractory material in the lower combustion chamber provides refractory surface on which the burning combustion gases and particulates expelled through the vertical passage impinge. | 07-23-2009 |
20100058998 | SOLID FUEL BOILER - The present invention relates to a solid fuel boiler, comprising a fire place with a burner, a flue gas passage with a flue gas outlet, an inlet for cold air, a convection space for heat exchange of cold air with the flue gas passage, and an outlet for hot air, wherein the flue gas passage comprises a tube kit with a plurality of tubes arranged adjacent to each other to create a flow space for air between the tubes, wherein at least one of said tubes is arranged so that it extends obliquely upwards in an acute angle in relation to the vertical line of the boiler from a lower attachment point to an upper attachment point. | 03-11-2010 |
20100064986 | BURNER, AND COMBUSTION EQUIPMENT AND BOILER COMPRISING BURNER - The present invention provides a solid fuel burner, which, while rendering the capacity larger than that in the conventional art, can suppress an increase in an unignited region and thus can realize the prevention of an increase in NOx concentration in a combustion gas and the prevention of a lowering in combustion efficiency, and a combustion equipment and boiler including the burner. The burner includes a fuel-containing fluid supply nozzle ( | 03-18-2010 |

20110297110 | WOOD PELLET BURNER FOR EXISTING BOILERS AND FURNACES - A pellet burner has inner and outer housings for defining a high pressure air plenum between. Angled perforations at strategic locations in the inner housing supplied pressurized primary and secondary combustion air so that, with pellets supplied to a burn pot of the inner housing and activation of a blower and an ignitor cartridge, the pellets auto-ignite and the air flow establishes a swirling flame in the burn pot that travels to a flame conduit of the inner housing where further swirling occurs in a venture section for shaping the flame into a clean, hot, symmetrical form. | 12-08-2011 |
20130145995 | LIGNIN FIRED SUPERCRITICAL OR NEAR CRITICAL WATER GENERATOR, SYSTEM AND METHOD - Methods are disclosed for providing recovered lignin of suitable quantity and quality to provide sufficient heating value to power the generation of supercritical or near critical water without the need for outside sources of energy. Supercritical or near critical water generator devices and systems are also disclosed. | 06-13-2013 |
20130276721 | BOILER - A boiler has a tank, a hearth contained in the tank, a gas pipe having one end in communication with a gas exit of the hearth and the other end passing through the hearth, a combustor in communication with a bottom of the hearth, and a fuel supply device being connected to a fuel inlet of the combustor. | 10-24-2013 |
20140150732 | ATMOSPHERIC HOT WATER HEATING SYSTEM - An atmospheric water heating system is presented, where hot gasses from a burner are introduced directly to water. The water is exposed to the burner exhaust gasses as a film upon a series of rotating discs partially submerged in a reservoir. The water vaporizes and then re-condenses on subsequent discs, cooling the exhaust gas and heating the reservoir water. The heated reservoir water may be used to heat space heating water with a water-to-water heat exchanger. The water vapor may be used to heat environmental forced hot air with a vapor-to-air heat exchanger. | 06-05-2014 |
