5Cu/(10NiO-NiFe2O4) cermet inert anodes were prepared by cold-pressing and sintering process, and the effect of superheat degree of melting K3AlF6-Na3AlF6-AlF3 on their anticorrosion performance was studied under electrolysis conditions. The results show that, the fluctuation of cell becomes small with increasing of superheat degree, which is helpful ...

Improving degree of superheat control in a direct expansion (DX) air conditioning (A/C) system
International Journal of Refrigeration, 2010Abstract In a direct expansion (DX) air conditioning (A/C) system having a variable-speed compressor and supply fan, the degree of refrigerant superheat regulated by a built-in conventional proportional–integral–derivative (PID) controller would experience fluctuation, after the speeds of both compressor and supply fan were regulated by a capacity ...

Evaluation of the State for the Material of the Live Steam Superheater Pipe Coils of V Degree
Advanced Materials Research, 2014The main aim of the undertaken research was to evaluate the state of the material of V degree live steam superheater pipe coils made of 10CrMo9-10 (10H2M) chromium-molybdenum steel as well as to determine their usability for further operation. The pipe coils came from a steam boiler working at a power plant.

A Machine Learning Method for State Identification of Superheat Degree with Flame Interference
2019The superheat degree in the process of aluminium electrolysis is an important indicator for judging the condition of the electrolysis cell. In the actual production process, the artificial observation of the fire hole is usually used for judgment and decision of cell condition. However, the decreasing number and frequent flow of experienced technicians
