The experimental results for seal clearances in two rotary heat exchangers are presented. The measurements were carried out by means of the method described in . Presented here are results of hot- and cold-state operations concerning rotary regenerators of about 5.3 and 9.4 m diameter.
Regenerative heat exchanger A regenerative heat exchanger, or more commonly a regenerator, is a type of heat exchanger where heat from the hot fluid is intermittently stored in a thermal storage medium before it is transferred to the cold fluid.
The Ljungström air preheater is more widely used than any other rotary heat exchanger in the steam generating industry. This is due, in part, to: high thermal effectiveness and proven performance; advanced heat transfer surfaces; bi-, tri- and quad-sector duct configurations; rotor and sealing system options with effective leakage control
Rotary regenerative heat exchangers are used for heat recovery, and are designed to transfer heat (non-hygroscopic version), or to transfer humidity (hygroscopic version) while simultaneously maintaining the ability to transfer heat from the outlet air to the inlet air.
The rotary heat exchanger permits reduced energy consumption by means of its high temperature efficiency of up to 90 %. In addition, humidity from the extract air can be transferred to the supply air, thus ensuring optimum air quality in practically all application areas.

Rotary Heat Exchanger DVC DVC is a rotary heat exchanger with a high level of efficiency that can also be used to transfer moisture from warm and humid extract air. This type of heat exchanger is one of the most efficient of the various heat exchanger systems.
Rotary heat exchanger is composed of alveolate heat wheel, case, drive system and sealing parts. The exhaust and outdoor air pass through half of the wheel separately, when the wheel rotates, the heat and moisture are exchanged between the exhaust and outdoor air. The energy recovery efficiency is up to 70% to 90%. Entering the cold air half

Rotary heat exchangers are an example of regenerative energy recovery systems. They are used for ventilation and air-conditioning (e.g. for residential buildings, offices, manufacturing facilities, cruise ships) and also in process air systems - namely, wherever it is possible and appropriate to recover heat energy, for example in waste ...
A seal assembly for a rotary heat-exchanger of a gas turbine is held in bearing contact with each end face of a regenerative rotor of the heat-exchanger to slidably support the regenerative rotor and to seal between a low-pressure gas passage and a high-pressure air passage of the turbine.
Hoval Enventus rotary heat exchangers are regenerators with rotating heat carrier for use in air handling systems and process technology. Depending on the air conditions and condition of the storage mass, they not only transfer heat but also moisture.
Rotary heat exchangers can be used in most types of applications. The three principal areas are comfort ventilation (e.g. homes, offices, hotels and airports); industrial ventilation (e.g. automotive industry) and marine ventilation (cruise liners and coastal environments).
Sleeves interrupt heat transfer, and overheat the rotary seal Sleeves interrupt the heat transfer path from the sleeve to the shaft, which results in significantly higher seal operating temperature, even if the shaft is hollow and contains a ... . Heat transfer considerations".

WED Heat exchangers of the WED range are used to cool process/barrier fluids in seal supply circuits. Designed as a tubular heat exchanger with integrated guide plates, the process/barrier medium is directed through the shell of the WED and the cooling medium through the tubes.
A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of an air-handling system or in the exhaust gases of an industrial process, in order to recover the heat energy.
