High Temperature Ceramic Heat Exchangers

There are three prime candidate industrial areas for ceramic heat exchangers.

High temperature ceramic heat exchangers.

These displacements are then used for detailed calculation of local stresses. Cal design studies of ceramic high temperature plate fin heat exchanger is presented. Ceramic hexs will exhibit better performance than state of the art metal based pches at a lower cost and also enable operation at higher temperatures 1023k. Process heat exchange power.

This approach allows the determination of local displacements by applying the outer heat exchanger boundary conditions on a substitute model. Designed to operate continuously up to 2400 degrees f. High temperature heat exchanger based on ceramic materials can be applied beyond the operating range of metallic high temperature alloys and thus represent a key component for increasing the. 150 psig high pressure heat exchangers are designed to operate with leakage rates of 0 5 2 percent are impervious to slag acids.

Ceramic heat exchangers the key properties for the selection of heat exchanger ceramics include. In contrast to previous studies the ceramic heat exchanger was operated with air under high temperatures up to 800 c and absolute pressure levels up to 5 bar. The methodology is based on. An advanced low cost corrosion and creep resistant thermal exchange system operating at temperatures 700 c and compatible to salt and gas phase htfs and s co 2 higher temperature power cycles will help seto program to achieve its lcoe targets demonstrated performance and associated data for a reliable ceramic hx at lab scale.

For industrial processes with temperatures above 900 c such as glass ceramics or metal production ceramic heat exchangers can raise the maximum temperature limit for waste heat recovery and thus lead to higher efficiencies. The heat to electricity conversion efficiency of closed cycle sco2 significantly increased 20 with an increase in turbine inlet temperatures from 823k to 1023k. Complete heat exchanger modules were produced and tested under simulated engine operating conditions up to 2300 f tube wall temperatures. Experimental tests resulted in thermal effectiveness from 0 65 to 0 97 when operating with volume flows between 20 and 160 n m 3 h 1.

Ceramic materials enable operation in high temperature and harsh environments and can so exceed the capabilities of comparable metal heat exchangers. Thermal shock resistance high temperature capability corrosion resistance and in some cases thermal conductivity.
