Application of quadratic regression orthogonal design to optimization surface heating for control wet steam condensation flow in nozzle

open access: yesCase Studies in Thermal Engineering, 2022
The condensed flow of wet steam in the low-pressure cylinder of a steam turbine will affect the safety and economy of the unit's operation. Therefore, it is necessary to reduce the influence of the wet steam on the turbine blades after condensation ...

Simulation and operation optimization analysis of multi-pollutant collaborative control of coal-fired flue gas based on high-temperature filtration

open access: yesMeitan xuebao, 2023
Aiming at the problems that the fly ash in coal-fired power plant flue gas can easily lead to the blockage of dust collectors and air preheaters, a 410 t/h coal-fired boiler in Shanxi was taken as the research object, and a coal-fired flue gas pollution ...

Effect of Contact Angle Hysteresis on Evaporation Dynamics of a Sessile Drop on a Heated Surface [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2022
Contact angle hysteresis (CAH) is a significant factor affecting the drop motion on solid substrates. A model of CAH is introduced to explore the influence of CAH on the dynamics of a sessile drop on a uniformly heated surface, and a two-dimensional ...

Study of the Structure and Catalytic Activity of B-Site Doping Perovskite for an Inferior Anthracite Coal Combustion

open access: yesEnergies, 2023
The unique structure and physical properties of perovskite-type catalysts make them highly promising for catalyzing efficient coal combustion. Mesoporous perovskite LaNixFe1−xO3 (x = 0.2, 0.4, 0.6, 0.8) coal combustion catalysts were synthesized using ...

Low Power Contactless Voltage Sensor for Low Voltage Power Systems [PDF]

open access: yesSensors, 2019
Contactless measurements represent the desirable solution in many contexts, where minimal cabling is required or, in general, cabling is not possible. This paper presents a new contactless voltage sensor for low voltage power systems. It is based on a contactless capacitive probe, which surrounds the power cable.

Low power, low delay [PDF]

open access: yesProceedings of the 11th international conference on Information Processing in Sensor Networks, 2012
ABSTRACT Traditionally, routing in wireless sensor networks consists of two steps: First, the routing protocol selects a next hop, and, second, the MAC protocol waits for the intended destination to wake up and receive the data. This design makes it difficult to adapt to link dynamics and introduces delays while waiting for the next hop to wake up.

Ultralow-Power SOTB CMOS Technology Operating Down to 0.4 V

open access: yesJournal of Low Power Electronics and Applications, 2014
Ultralow-voltage (ULV) CMOS will be a core building block of highly energy efficient electronics. Although the operation at the minimum energy point (MEP) is effective for ULP CMOS circuits, its slow operation speed often means that it is not used in ...

Effect of high-temperature and rapid pyrolysis condition of rice husk on the evolution of char structure

open access: yesMeitan xuebao, 2023
The conversion level of carbon in the process of biomass char utilization determines the overall efficiency of subsequent utilization, while the conversion rate of biomass char depends to a certain extent on the physical and chemical structure of biomass.
