Rapid cooling or quenching of gas streams is used in a number of essential applications in the petrochemical industries. Examples of processes with gas quench systems include: reactor outlet, incinerator, coal gasifier, power plant absorber gas inlet. The selection and sizing of spray nozzles are the most critical decisions in the system design. Fog Nozzle is qualified without equal to help you with your spray quenching needs. We have assisted in the design of hundreds of systems for our customers in the past 30 years. We optimize gas-quenching systems to reduce quench vessel size, reduce atomization energy consumption, and minimize the risk of unexpected downtime, which obtains the economic benefits of capital and operational cost savings. Our Applications Engineers incorporate engineering fundamentals, product knowledge, design experience and your operating constraints to develop a reliable and cost effective quench system.   Desulphuriztion nozzles RBSC (SiSiC) desulphurization nozzles are the key parts of flue gas desulphurization system in thermal power plants and large boilers. They are widely installed in the flue gas desulphurizaiton system of many thermal power plants and large boilers. Single direction nozzle In the 21st century industries world wide will face increasing demands for cleaner, more efficient operations. ZPC company is committed to doing our part to protect the environment. ZPC specializes in spray nozzle design and technological innovation for the pollution control industry. Through higher spray nozzle efficiency and reliability, lower toxic emissions into our air and water are now being achieved. BETE’s superior nozzle designs feature reduced nozzle plugging, improved spray pattern distribution, lengthened nozzle life, and increased reliability and efficiency. This highly efficient nozzle produces the smallest droplet diameter at the lowest pressure resulting in reduced power requirements for pumping. ZPC has: • The broadest line of spiral nozzles including improved clog-resistant designs, wider angles, and a complete range of flows. • A full range of the standard nozzle designs: tangential inlet, whirl disk nozzles, and fan nozzles, as well as low- and high-flow air atomizing nozzles for quench and dry scrubbing applications. • Unparalleled ability to design, manufacture and deliver customized nozzles. We work with you to meet the toughest government regulations. We can meet your special requirements, helping you to achieve optimum system performance. Brief Description of FGD Scrubber Zones Quench: In this section of the scrubber, the hot flue gases are reduced in temperature before entering the pre-scrubber or absorber. This will protect any heat sensitive components in the absorber and reduce the volume of the gas, thereby increasing the residence time in the absorber. Pre-Scrubber: This section is used to remove particulates, chlorides, or both from the flue gas. Absorber: This is normally an open spray tower that brings the scrubber slurry into contact with the flue gas, allowing the chemical reactions that tie up the SO 2 to take place in the sump. packing: Some towers have a packing section. In this section, the slurry is spread on loose or structured packing in order to increase the surface in contact with the flue gas. Bubble Tray: Some towers have a perforated plate above the absorber section. Slurry is deposited evenly on this plate, which both equalizes the gas flow and provides surface area in contact with the gas. Mist Eliminator: All wet FGD systems generate a certain percentage of extremely fine droplets that are carried by the movement of the flue gas toward the tower exit. The mist eliminator is a series of convoluted vanes that trap and condense the droplets, allowing them to be returned to the system. In order to maintain high droplet removal efficiency, the mist eliminator vanes must be cleaned periodically.
