Cooling & Quenching
Process cooling and Zero Liquid Discharge (ZLD) with Gas Conditioning Towers (GCT)
Gas conditioning towers (GCT) are used in industrial applications to cool gases upstream of electrostatic precipitators / bag filters for effective temperature control, gas volume reduction and humidification by the evaporation of water. GEA provide the two available atomization technologies utilized in the evaporative cooling process are hydraulic atomization and twin-fluid atomization. Key parameter for GCT sizing is in addition to the amount of flue gas, inlet and outlet temperature mainly the attainable droplet size and the associated energy consumption.

Hydraulic atomization with single fluid, spillback nozzles with larger droplet sizes provide less energy consumption but require a larger casing design and more purity on the cooling water. The amount of liquid injected is adjusted via a control valve in the spillback line, whereby part of the flow is taken from the inlet flow rate and returned to the buffer tank.
Twin fluid technology utilizes compressed air or steam to atomize the water into droplets via a spray injection nozzle/lance as well. The water and compressed air (the two fluids) combine inside the nozzle and exit into the flue gas stream. Smaller droplet sizes lead to smaller casing design and even wastewater can be used for Zero Liquid Discharge (ZLD) where recovered waste heat supports efficient evaporation of water for compliance with wastewater discharge limits.
The GCT casing structural design covers full under pressure of ID fan and is providing adequate gas distribution with deflection-, guide- and perforated sheets in the inlet area.
The transport of dust from the housing is taken into account for possible malfunctions with a reversible paddle screw and motor-driven double pendulum flaps on both sides.

Rapid cooling of quenching of gas streams is used in a number of essential applications in the process industries. The selection and sizing of spray nozzles are the most critical decisions in the system design. GEA quench tower design consists of an open vessel in which liquid is sprayed to contact the gas. The gas enters the bottom of the tower...
GEA’s past fiscal year was one of significant growth and further profitability gains. In particular, the technology group substantially increased order intake, with all divisions contributing here. GEA also made progress in all Mission 30 strategic growth areas. In addition, GEA met key interim targets under its climate plan ahead of schedule. Major milestones in fiscal year 2025 were admission to the DAX index, the award of one of the largest contracts in the company’s history, and streamlining of the corporate structure.
Благодаря новому производственному комплексу SmartParc предприятия пищевой промышленности в Великобритании сокращают эксплуатационные расходы и выбросы в атмосферу. Эта модель совместного производства, в основе которой лежит технология нагревания и охлаждения GEA, демонстрирует, как инновации ускоряют реализацию отраслевых амбиций по достижению нулевого уровня выбросов.
«Сварить яйца так же просто как и сварить пиво». Это такое сравнение, которое заставляет вас улыбнуться — и тут что-то щелкает в голове: что-то сложное вдруг становится простым. В этом фильме, действие которого происходит в сельскохозяйственной глубинке США, мы рассматриваем прецизионную ферментацию и реальную работу, необходимую для превращения идеи в продукты питания.
