Flame stabilization disc with adjustable blade angle

Abstract

The invention relates to a flame stabilizing disc with adjustable blade angles, which comprises an inner ring and an outer ring, and the inner ring and the outer ring are connected by an inner and outer ring fixing frame; the inner ring and the outer ring are respectively formed There are several first small round holes and several second small round holes, blades are connected between the first small round holes and the corresponding second small round holes, and the two ends of the blades are respectively connected with the first small round holes. The rotating shaft matched with the second small circular hole; the outer ring is connected with an angle adjustment mechanism for blade angle adjustment; the structure of the invention is simple, and when the size and shape of the fuel oil, the furnace or the drum change, the angle can be adjusted The adjustment handle and the support screw of the flame stabilizing disc can conveniently realize the adjustment of the blade angle of the flame stabilizing disc and the adjustment of the front and rear positions of the flame stabilizing disc, so as to adjust the swirl state of the combustion air, so that the combustion air and fuel can be fully mixed and burned to reduce carbon deposits And form a flame that matches the size of the furnace or drum to better meet production requirements.

Description

technical field [0001] The invention relates to the technical field of burners for asphalt mixing plants, in particular to a flame stabilization disk with adjustable blade angles. Background technique [0002] The production of asphalt mixture often requires the use of a burner to dry and heat the aggregate first, and the flame stabilization plate is an important component of the burner. After the fuel is ejected from the nozzle, it is immediately ignited by the high-temperature flue gas, forming a flame of a certain size and shape, which ensures the stability of combustion. [0003] Now, the flame stabilization disc blades of the burner are often fixed. When the size and shape of the fuel oil, the furnace or the drum changes, the swirling state of the combustion air needs to be adjusted to make the combustion air and the fuel fully mix and burn to reduce carbon deposition and reduce carbon deposits. A flame matching the size of the furnace or the drum is formed, but the pr...

Problems solved by technology

[0003] However, the blades of the burner flame stabilization plate are often fixed now. When the size and shape of the fuel oil, furnace or drum change, it is necessary to adjust the swirling state of the combustion air so that the combustion air and fuel can be fully mixed and burned to reduce carbon deposits and Form a flame that matches the size of the furnace or drum, but only by adjusting the air-oil ratio or air-air ratio cannot meet the production requirements well. Therefore, a flame stabilization plate with adjustable blade angles can overcome the above shortcomings
