Heat transfer between two different temperature fluids is of great importance for most industrial processes. The main design constraints of industrial heat exchangers are tube stress, accessibility, systems dimensions and ease of maintenance.
Bayonet heat exchangers are vertical, often relatively small, liquid evaporators that use steam as a heating medium, with free tube expansion capabilities and with an internal separation volume to prevent entrainment. Load variation can be controlled by the liquid level on the evaporation side.
Steady state fluid temperatures and the related boundary conditions are obtained from the energy balance on control volume of a bayonet tube.
In our design, the total pipe length and the length of clearance area play an important role in determining the bayonet tube performance in terms of pressure drop and heat transfer. We obtain the optimum combination of design and operating parameters in order to maximize the efficiency and performance of the bayonet tube.
This results in a solution that can stand extreme temperatures and improve performance.
