Results from testing heat-recovery accumulator

Many different sources are used for obtaining and supplying heat, which do not require immediately fuel combusting. However, as a rule, such sources do not allow independently controlling an amount of heat to be supplied, while heat consumption is an independent process. Matching heat production and consumption curves is usually done using heat accumulators. Heat-recovery accumulator for utilizing waste-gases heat of a small-capacity power station was developed, fabricated and tested. To exclude superheating of the accumulator working fluid, a system of "thermodynamic" self-controlling of heat utilization was applied. The tests conducted confirmed the rated characteristics of the developed heat-recovery accumulator, as well as a reliability of self-control system. © 2018 Institute of Physics Publishing.
