The difference between ground torches and elevated torches

Thread Content

The differences between ground torches and elevated torches are as follows: 1. Ground torches have a lower processing capacity than elevated torches, and they cannot burn toxic gases. 2. Starting the ground torch too early can cause backfire, while starting it too late can result in pressure buildup. 3. For elevated torches, due to the relatively high exit velocity of the torch gas, the noise generated by combustion is inevitable. 4. When the overhead flare is burning, the thermal radiation generated by the large flames at the tip of the flare has a significant impact on the workers and equipment located near it. 5. From an environmental perspective, ground-based torches are better than those mounted on structures. 6. In terms of investment and maintenance, ground-based torches have higher costs, but they require lower operating expenses and are easier to maintain. Related extensions: 1. The ground torch consists of a ground combustion furnace, pillars for the ground combustion furnace, ground burners, windproof and noise-reducing walls, a staged combustion system, as well as an automatic lighting device for the eternal flame, safety measures, a control system, and an air release system. The combustion of the torch gas takes place within the body of a cylindrical ground combustion furnace. The combustion process is enclosed; no flame is visible from the outside, there is no light pollution, and heat radiation is low. The cylindrical floor combustion furnace is equipped with a certain number of floor burners of a special design. The surface burner features a plum blossom-shaped porous structure that divides the large streams of flame gas into many smaller streams, facilitating mixing with air and increasing the contact area with air to achieve smoke-free combustion. The mixing of air with flare gas is primarily achieved through the pressure of the flare gas itself and a specially designed burner. 2. The elevated torch consists of an automatic control system, a ignition system, steel structural supports, and an upright rising pipe. The flame is kept away from the ground, igniting and burning automatically at its tip. The height of the high-altitude combustion tower can be adjusted, ranging from a minimum of 5m to a maximum of 200m. The torch head is equipped with a permanent flame, which remains lit after being ignited by an igniter; whenever exhaust gases reach the torch head, they are immediately ignited by this permanent flame. The torch tip is installed at the top of the torch tower, which helps to reduce radiation into the environment and minimize the spread of toxicity. The three common support methods for torch towers are as follows.
