Heat exchanger is the device which makes transfer of heat between two fluids possible. It has many great industrial applications, and is for cooling or heating purposes.
Heat exchanger finds its applications in several heavy industries, like, coal, mining, steel, pulp, etc.
Type of fluid and its pressure determines which to use. A plate heat exchanger is designed especially for heat transfer between low and medium pressure fluids.
Shell and tube exchanger are more suitable for high pressure applications. While for cooling, a circulating fluid air cooled heat exchangers are preferred.
Anaerobic digestion is a common process in the production of biogas. This process involves:
One of its key applications is in the sewage sludge treatment process.
Plate heat exchanger possesses thin plates connected with each other with tine space between the two to let the fluid flow between larger surface areas. These are compact and very efficient for transferring heat between low and medium pressure fluids.
For high pressure applications, shell and tube that consists of bundle of tubes inside a shell to transfer heat from within it and around it is an ideal instrument.
Air cooled heat exchangers have fine tubes and it cools a liquid by forcing the air to the exterior of the tubes in which the fluid circulates.
So, all your requirements, such as, waste water, sludge to sludge, or even sludge to water can be fulfilled with Klean-Wall heat exchanger. Also, it improves the digester performance by breaking up and mixing municipal sludge.
