What requirements must be met regarding the height of the temporary chimney in a desulfurization tower?
Thread Content
When carrying out anti-corrosion measures on chimneys in desulfurization projects, it is sometimes necessary to install temporary chimneys at the top of the desulfurization towers. What requirements should the height of these temporary chimneys meet? Please feel free to speak up!
The height of chimneys is determined in accordance with relevant standards: there are emission standards for boiler air pollutants, corresponding standards for thermal power plants, standards for industrial furnaces, as well as comprehensive emission standards for air pollutants. The key is to meet the concentration requirements and the emission rate requirements.
According to the emission standards for air pollutants in thermal power plants, the height of temporary chimneys should be at least over 100 meters, whereas the temporary chimneys used in actual construction projects generally do not exceed 60 meters.
For temporary chimneys, is it necessary to consider seismic loads during design?
Taking all factors into account, such as wind load, seismic effects, and the strength of the tower, the specific height is determined by the local environmental protection agency.
As long as the fire and explosion prevention requirements are met, and toxic pollutants can be diluted to environmentally acceptable levels before reaching the ground surface, the height of the chimney can be determined through calculations; generally, this is done based on experience
It is usually 90 meters in height
A temporary chimney needs to be 5 meters taller than the surrounding buildings, and that’s sufficient. Remember to recover as soon as possible……
