Abstract

The invention provides an ejection type combustion device. The ejection type combustion device comprises a plurality of Venturi combustors and multiple layers of protective covers which are arranged around the Venturi combustors in the axial direction of the ejection type combustion device; each layer of the protective cover is circumferentially closed to form a flame cavity with an upper-end opening and a lower-end opening, the radial size of the previous-layer protective cover is larger than that of the next-layer protective cover in the every two axially-adjacent layers of protective covers, at least one layer of the protective cover is provided with ejection holes which penetrate through the wall faces of the bottom ends of the protective covers, and then the purpose of increasing the air ejection capacity is achieved. According to the ejection type combustion device, the design concept is ingenious, the structure is simple and easy to achieve, the cost is low, and the problems that an ejection type combustion device is insufficient in ejection capacity and combustion, poor in emission and the like can be effectively solved.

Description

technical field [0001] The invention relates to an ejector type combustion device, in particular to a protective cover structure of the ejector type combustion device. Background technique [0002] In petrochemical plants, the torch prevention and control system can deal with the excess, harmful and unbalanced waste gas discharged from the production plant in a timely manner, and can also deal with the unqualified gas generated during commissioning, start-up and shutdown, and a large amount of gas released instantaneously in the event of an accident. The device operates normally and safely. [0003] The venting flare system generally adopts an ejector combustion device, which includes several layers of Venturi burners to burn the gas. Several layers of shield rings are placed around these Venturi burners to form a flame cavity that blocks heat radiation. At the same time, the bottom end of these shields should form an ejection area to inhale air to participate in the combu...
