Abstract

An adjusting device for a gas burner comprises a distribution chamber, within which a static pressure chamber is formed. The distribution chamber is provided with a main vent connected to the static pressure chamber and several secondary vents. A sealing mechanism for sealing the secondary vents is installed on the distribution chamber. The sealing mechanism consists of a cylinder and a seal driven by the cylinder, which controls the switch of the secondary vents. The sealing mechanism is provided with a vent for releasing excess air volume. An air inlet connected to the static pressure chamber is provided on the distribution chamber, with the main vent always connected to the static pressure chamber. Compared to prior art, the seal is controlled by the cylinder to seal the secondary vents, thereby blocking the air intake for the corresponding combustion zone.

IPC Classes  ?

• F23D 14/62 - Mixing devicesMixing tubes
• F23D 14/02 - Premix gas burners, i.e. in which gaseous fuel is mixed with combustion air upstream of the combustion zone
• F23D 14/78 - Cooling burner parts

Abstract

Embodiments provide a combustion structure that can achieve stable combustion by addressing the aforementioned drawbacks in the prior art such as low flam stability, backfire, deflagration, blockage and/or any other drawbacks. The combustion chamber structure in accordance with the disclosure can include: a grate structure including a first set of elongated components, a fire retention structure including a second set of elongated components. The first set of first elongated components can be arranged along an axial direction within the combustion chamber structure. The second set of elongated components can be arranged along the axial direction in a same direction as the first elongated components. The second set of elongated components can be configured to generate a negative pressure zone within the combustion chamber. The first set of elongated components can form apertures that can be aligned with apertures formed by the second set of elongated components.

IPC Classes  ?

• F22B 31/04 - Heat supply by installation of two or more combustion apparatus, e.g. of separate combustion apparatus for the boiler and the superheater respectively
• F22B 21/14 - Water-tube boilers of vertical or steeply-inclined type, i.e. the water-tube sets being arranged vertically or substantially vertically built-up from substantially-straight water tubes involving a single upper drum and two or more lower drums
