A combustion chamber assembly unit for a fuel-operated vehicle heater is provided. The combustion chamber assembly includes a combustion chamber housing (12) with a combustion chamber (18), which is defined by a circumferential wall (14) and by a bottom area (16). An oxidation catalytic converter device (54), through which combustion waste gases can flow, is provided downstream in relation to the combustion chamber (18). The combustion chamber assembly further includes a hydrocarbon storage device (74) or/and a nitrogen storage device (76).

A method and apparatus for treatment of unburnts utilizing oxygen carrier particles, which may be CLOU particles, oxidized in an air reactor and transmitted to a post oxidation reactor as shown in FIG. 2. A flue gas stream containing unburnts is injected into post oxidation reactor wherein unburnts are oxidized by oxygen supplied by oxygen carriers. Reduced oxygen carriers are separated from post oxidation reactor and transmitted back to air reactor for re-oxidation. An embodiment may include a post oxidation chamber, which may be catalytic, receiving a portion of flue gas stream and oxygen from a flue gas stream of post oxidation reactor.

A vented combustion chamber for an insect attractant engine is provided for a flying insect trapping device of the type that relies upon combustion of a fuel to generate a flow of carbon dioxide to attract flying insects. The combustion chamber, which is generally tubular and horizontally oriented in operation, is vented through a hole formed in one side of the chamber wall that extends from the outer surface of the chamber into the interior thereof. During operation of the device, this through-hole allows gas inside the chamber to be vented to the outside, changing the effective length of the combustion chamber for the purposes of wave generation is changed so that creation of a resonance cycle or standing wave, and the resulting acoustic phenomenon of howling, is prevented.

The present invention provides an infrared hydrogen/oxygen combustor. The structure of the combustor includes a sinus ring (1). A surrounding foot (12) of the angle-shaped sinus ring (1) wraps a material-containing basin (14). A first small tube (16) and a second small tube (7) are connected the material-containing basin (14) and the angle-shaped sinus ring (1). Water solution (3) is contained in the material-containing basin (14). A straight-hole ceramic water-absorbing board (5) is provided on the upper part of the water solution (3), a spacing ring (6) is provided above the side of the material-containing basin (14) and in the upward ring of the angle-shaped sinus ring (1), a two-stage material-containing box (9) with a separated brake is provide on one side of the angle-shaped sinus ring (1). The technical scheme of the invention reduces the production cost, the pollution and protects the environment.

In a combustion system, a charge source is configured to cooperate with a collection plate and a director conduit to cause at least one particle charge-to-mass classification to be reintroduced to a flame for further reaction.

A combustor for providing homogeneous combustion of liquid fuels includes an essentially tube shaped combustion body, including a combustion chamber having a plurality of reaction zones, one of which is an injection zone, the others being combustion zones for staged homogeneous combustion of evaporated fuel and air. A swirler, including a base and swirler elements, is configured to operate at a swirl number between 0.6-2.5 in combination with a flow constriction plate whose size is such that the ratio of the open diameter (De) of the constriction to the diameter (D) of the combustion body is <0.7 and the constrictor plate is placed at a distance (L1) from the base of the swirler base so that L1/De>1. A primary mixing plate is placed downstream from the constriction plate at a distance (L2) so that the ratio L2/L1<1 to allow maximum mixing of the homogeneous combustion.
