YANKEE HOOD PROCESS AIR SYSTEMS
At Enerquin, we engineer our products for results. Our Hood Air Systems offer a prime example. Designed to meet specific production requirements, each individual system is based on an equilibrium between impingement air velocity and impingement air temperature. This balance ensures optimal gas and electrical efficiency, which drives down your costs. Our systems are guaranteed to maintain hood air balance under nearly all operating conditions and fan motor and burner energy consumption is always optimized. Ambient conditions around the Yankee Hood and the related process air systems are always maintained.
MONO SYSTEM
The "Mono" air circulation system is offered for its compact design and to reduce initial capital cost. There is one circulation fan with one burner and gas train system feeding both hood halves.
BENEFITS
Air systems take less space;
Initial cost is lower;
Less maintenance.
DUO SYSTEM
The "parallel" air circulation system is offered to provide maximum drying capacity while keeping each hood air circulation system independent, for easy balancing and flexibility in operation.
BENEFITS
Independence of the wet-end and dry-end hood to ease operation;
Possibility to run with one (1) fan/burner in a cross-over operation.
CASCADING SYSTEM
In addition to the benefits of the “Duo” system, the "Cascading" air circulation system is offered to provide maximum drying capacity with reduced energy consumption. A portion of the hot recirculated air from the dry-end hood is used as make-up air for the wet-end hood.
BENEFITS
Better thermal efficiency;
Evacuation from the wet-end hood;
High humidity operation;
Higher concentration of energy in the exhaust.
RETRACTION SYSTEM
Each hood half can retract independently or in unison. The hood retraction system is designed to provide an adequate nominal clearance between the Yankee shell and Enerquin Yankee hood impingement surface, while maintaining the hood above the dryer surface at optimized impingement distance during Normal operating.
BURNER AND GAS TRAIN
          
Each burner and gas train is designed for easy ignition and safe operation while adjusting for various temperature set points and fluctuating back pressures in the combustion chamber. The burner and gas train are sized for heating the air to the desired temperature. All components are leak tested and pre-assembled in the factory as much as possible. Burners can be designed for gas, oil or both. Necessary controls are provided for a safe and efficient operation.
SHELL HEATER
Each shell heater is designed for optimum combustion and to evenly transfer the heat, generated by the burned fuel, to the Yankee hood supply air. Steam heating coils can also be used for low supply temperature applications.
VOLUME CONTROL DAMPERS
Dampers are designed for high temperature operation. All operators are pre-installed and tested in the factory.
Are your Process Air Systems optimized?
Yankee air systems are energy intensive and should routinely be checked to ensure that they run at an optimal level.   more
