Technical Categories: 
Critical Need: 

Heat exchangers are critical to efficient thermal energy exchange in a variety of applications, including electricity generation, transportation, petrochemical plants, waste heat recovery, and more. Heat exchangers designed to handle very high pressures and high temperatures simultaneously are more efficient and compact. Their design also requires finer heat transfer surface and fin features at the limits of existing manufacturing capabilities with high temperature materials. Durable, reliable, and cost-effective higher temperature and pressure heat exchangers that exceed current operating conditions could reduce fuel consumption, system footprint, and capital cost while boosting the performance of a variety of power generation and industrial processes.

Project Innovation + Advantages: 

Missouri S&T will combine a novel additive manufacturing technique, called ceramic on-demand extrusion, and ceramic fusion welding techniques to manufacture very high temperature heat exchangers for power cycles with intense heat sources. Enabling turbine operation at significantly higher inlet temperatures substantially increases power generation efficiency and reduces emissions and water consumption. The developed heat exchangers will use ultra-high temperature ceramic materials and state-of-the-art design tools and manufacturing techniques to operate under temperatures of 1100-1500°C (2012-2732°F) and pressures of 80-250 bar (1160-3626 psi). Their high pressure and high temperature characteristics offer great potential for power plant size and cost reduction to enable future high efficiency modular power generation systems.

Potential Impact: 

HITEMMP projects will enable a revolutionary new class of heat exchangers and innovative approaches to advanced manufacturing with applications for a wide range of commercial and industrial energy producers and consumers.

Security: 

High performance, efficient heat exchangers would increase industrial productivity, supporting domestic industries. The developed manufacturing techniques for high temperature materials could strengthen U.S. leadership in advanced manufacturing.

Environment: 

More efficient electricity generation and industrial processes could significantly reduce emissions by enabling more efficient operations.

Economy: 

HITEMMP technologies could enable more cost-effective, efficient, and compact modular power generation systems for multiple applications.
