A smoke stack is a tall structure designed to emit smoke and gases from industrial processes, such as those found in factories or power plants. It helps to disperse pollutants into the atmosphere, reducing their concentration near the ground. Smoke stacks are often made of materials like steel or concrete and can vary in height depending on the facility's needs. The primary function of a smoke stack is to improve air quality by allowing harmful emissions to rise higher into the atmosphere, where they can be diluted. This is important for compliance with environmental regulations and for minimizing the impact on nearby communities and ecosystems, including air quality and public health.
