Dry Cooler For Power Plant Auxiliary Cooling
Dry Cooler For Power Plant Auxiliary Cooling
Professional dry cooling solutions specially engineered for power plant auxiliary cooling systems, widely applied in thermal power, gas power, combined cycle power plants, biomass and cogeneration plants. It provides reliable closed-loop heat rejection for all auxiliary equipment, replacing traditional cooling towers with water-saving, low-maintenance and high-reliability performance.
Application Scope in Power Plant Auxiliary Cooling
Dry coolers are the core cooling equipment for power plant auxiliary loops:
Generator lube oil cooling
Transformer oil cooling system
Compressor and pump unit auxiliary cooling
Gas engine HT/LT circuit cooling
Plant closed-loop circulating water & water-glycol cooling
MCC room, frequency converter and electrical equipment cooling
Working Principle
The dry cooler adopts fin&tube heat exchanger structure. Hot circulating medium (water / water-glycol / lube oil) flows inside the coil, and axial forced draft fans take away heat through ambient air sensible heat exchange.Fully closed-loop operation, no contact with outside air, no evaporation loss, suitable for long-term continuous operation of power plants.
Main Technical Configuration
Heat exchanger coil: Copper tube aluminum fin / stainless steel anti-corrosion coil
Frame: Hot-dip galvanized steel or stainless steel
Fan: Low noise axial fan, optional VFD variable frequency drive
Control system: PLC intelligent temperature control, group control and remote monitoring
Medium adaption: Pure water, 30%–50% water glycol mixture, industrial lube oil
Market Application
Suitable for gas-fired power plants, thermal power plants, CHP cogeneration plants, biomass power stations and industrial self-provided power plants, especially ideal for Middle East, UAE, Saudi Arabia and Southeast Asia large-scale power project supporting.
We provide custom dry cooler design according to power plant cooling capacity, medium type, inlet/outlet temperature, flow rate and on-site installation space. Provide thermal calculation, structural drawing and one-stop auxiliary cooling overall solution.
