It’s always fun checking out the latest and greatest the industry has to offer at the ASHRAE show. (Fun for Engineer types like us anyway…)
The 2019 show was in Atlanta. One highlight was seeing the Practical Steam Engine from Maxi-Therm in action while touring the Practical Steam factory in Kennesaw, GA. This engine generates power through the expansion of steam from high pressure to low pressure.
The following video shows the R&D/demo unit generating running about 16kW of 379V at 80-82 dB. Production models can match whatever electrical output is required at less than 75 dB! This is the perfect application for electricity generation in parallel to a steam PRV station, providing an extremely short paybacks on the equipment and installation costs.
The smallest unit is up to 5,000 lbs/hr and the largest is up to 20,000 lb/hr, all with 5:1 turndown. Multiple units can work together for larger steam flow requirements. Contact HTS for more info.
