Name three different particle control technologies.

Question: Name and briefly describe three different particle control technologies used in various industries. Answer: Three different particle control technologies include: 1. Electrostatic Precipitators (ESP): ESPs apply a high voltage charge to particles in the gas stream, which are then collected on grounded plates and removed periodically for disposal. This technology is commonly used in power generation and industrial sectors. 2. Cyclone Separators: These devices remove large and coarse particles from a gas stream by using centrifugal force. The gas stream enters at high velocity, and particles are pushed toward the outer wall, spiraling downward for collection and disposal. 3. Baghouse Filters: Also known as fabric filters, these filters capture fine particles in industries like power generation and manufacturing. The gas stream passes through fabric filter bags, trapping particles while allowing gas to pass through. Particles are periodically removed from the bags using compressed air or mechanical shaking.
