Torch combustor adapting to high load, multiple work conditions and high-low heat value

Abstract

The invention relates to a torch combustor adapting to the high load, multiple work conditions and high-low heat value, and particularly, the torch combustor has the capability of treating the high heat value and low heat value flare gas at the same time. The torch combustor comprises a cylinder, a bottom purging steam pipe, a tracing pipe, a nightlight, a silencing cover, center injection steam pipes, a high-altitude igniter, an accompanying combustor and a small-flow cylinder. The small-flow cylinder and the cylinder are connected side by side and in parallel. The nightlight and the high-altitude igniter are connected to the position, close to the small-flow cylinder, of the cylinder. The bottom purging steam pipe is arranged in the cylinder, and the center injection steam pipes are welded to the cylinder in a penetrating manner and evenly distributed in the cylinder. The silencing cover is connected to the middle portion of the cylinder, and the tracing pipe is laid on the inner wall of the silencing cover. The accompanying combustor is arranged on the outer side of the cylinder. The torch combustor can be suitable for treating the high-heat-value flare gas and can also meet the requirement for exhausting of low-heat-value flare gas.

Description

technical field [0001] The invention relates to a torch burner suitable for large load, multiple working conditions and high and low calorific value, especially capable of processing high calorific value and low calorific value flare gas at the same time. Background technique [0002] The flare burner is the core equipment in the flare system for venting combustible gas. With the increasing scale of petrochemical enterprises, the discharge conditions of flare gas are complex and changeable, and the calorific value of the discharge gas varies widely. At present, the flare burner is only designed for the change of the discharge amount or the calorific value of the exhaust gas. It has a single function, and it is difficult to meet the changes of the load and the calorific value at the same time. For the emission of low calorific value flare gas, reduce the flow rate of the flare gas outlet, set up the burner to burn and heat the flare gas, usually the ignition and burning of th...
