摘要： In accordance with the flow distribution of combustion gas including an unburned portion, an after-air port (AAP) arranged downstream of the two-stage combustion burner can effectively reduce the unburned portion by dividing as appropriate so as to avoid interaction, and by mixing together, two types of after-air having functions of linearity and spreading. As the configuration of this AAP, a primary nozzle for supplying primary after-air and having a vertical height greater than the horizontal width is provided in the center in the opening of the AAP, a secondary nozzle for supplying secondary after-air is provided in the opening outside of the primary nozzle, and one or more secondary after-air guide vanes having a fixed or variable tilt angle relative to the after-air port center axis are provided at the outlet of the said secondary nozzle to deflect and supply the secondary after-air horizontally to the left or right.

摘要： Disclosed is a fireplace which includes a firebase, a primary combustion zone with a first air supply unit, a secondary combustion zone, and an exhaust flue. The fireplace place also includes a charcoal/reduction layer which forms between the primary combustion zone and the secondary combustion zone, the arrangement and construction being such that the gases and/or particulate matter produced from the pyrolysis and/or combustion of the biomass fuel in the primary combustion zone have to pass over, or through, the charcoal/reduction layer prior to entering the secondary combustion zone and/or the exhaust flue. The fireplace also includes a second air supply unit for introducing heated secondary air into, or adjacent to, the secondary combustion zone, the arrangement and construction being such that the secondary air passes through (or adjacent to the region of) the charcoal/reduction layer to thus heat the secondary air.

摘要： A reactor for reducing the contents of nitrogen oxides and sulphur oxides in combustion gases. The reactor is in the form of a post-combustion chamber to be connected after a combustion chamber. The reactor has a casing including a generally cylindrical main part transforming at its top into a dome-shaped outlet part with an outlet opening. Around the casing of the reactor, there is provided a heat-insulated wall whose inner side has substantially the same shape as the casing and which is eccentrically disposed in relation to the casing. The casing of the reactor accommodates a partition which is conical and has its apex directed towards the outlet opening. A gap is formed between the shell and the partition. At the inlet end of the shell, an inlet funnel is provided at a certain distance from the inlet end as so to form a gap. A heat exchanger is provided for preheating secondary air supplied through a secondary air intake into the gap between the casing and the wall at a certain distance from the opening. At the bottom, the gap is connected to a collecting box and an outlet pipe.

摘要： A stove having automatic chimney air flow compensation for reductions in air flow to its combustion chamber is disclosed. An increase or decrease in compensatory air flow is dependent upon the movement of ganged dampers. The amount of compensatory chimney air flow is dependent upon the size and/or position of apertures and blocking portions formed respectively in the ganged dampers. The dampers can be configured, as appropriate, and thereby tuned, to be particularly responsive to local conditions.The stove is provided with a conduit positioned to provide a source of fresh air. The conduit is clamped to the stove to heat the air flowing therein and thereby prevent exhaust gas condensation and creosote buildup when it rises in and from the chimney. One of the ganged dampers is inserted into the conduit and acts, due to the nature of its linkage with the stove damper, to block air flow therein when the linkage with the stove damper, to block air flow therein when the stove damper increases air flow to the combustion chamber and increase conduit air flow when the flow of stove inlet air is reduced. This inverse and automatic damper action makes it easy and efficient for a user to adjust stove combustion rates with significantly reduced concern about chimney fire.

摘要： A bio-mass burner having a continuous feed on demand to a first combustion chamber that contains a hollow grate structure. The novel method of operation includes the use of at least one venturi tube which is in fluid communication with the hollow grate structure to establish an air flow into a second combustion chamber. Primary air to support combustion in the first chamber is supplied to the underside of the grate structure. Secondary air to support combustion in the second chamber is supplied through the hollow grate structure and then to the venturi tube in a sufficiently tortuous path through the first combustion chamber to insure that the air is superheated at the outlet of the venturi tube. A baffle arrangement in the first combustion chamber directs the fuel product toward the grate structure and assists in preventing any unburned gases from being ejected into the atmosphere.
