Bayonet Heat Exchanger
Bronswerk Heat Transfer delivers Bayonet Heat Exchangers designed to efficiently heat up the fluid (mostly by using the saturated LP/HP steam). The Bayonet tube heat exchanger typically consists of a pair of concentric tubes. The outer of which has closed end caps/plates that create a clearance pass between the inner and annulus tube.
For optimal results, the tube bundle is completely immersed in the tank and the heating coil is directly exposed to the fluid.
The best welding techniques for Bayonet Heat Exchangers
Bronswerk Heat Transfer starts every order for a Heat Exchanger with clarifying the specific customer needs and devising a proposal that offers more, better or more innovative solutions than the client was asking for.
When designing Bayonet Heat Exchangers, we focus on selecting a suitable tubes diameter ratio to minimize the inner tube pressure drop and at the same time optimize the heat transfer performance.
We are entirely focused on the situation of the customer.
The possibility of using high temperature heating streams
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.
