Due to the abundant coal reserves in China, coal is expected to be the most important energy resource in the future. The ash deposition/slagging behavior can obviously affect the heat transfer efficiency of heat transfer tubes in boiler, and cause increasing coal consumption. In order to clarify the effect of ash deposition behavior on heat transfer characteristics of the tube in boiler, a pulv...

Boilers are among the most common heating equipment in commercial facilities, often consuming the majority of a facility’s fuel. The load on a boiler plant in a commercial facility constantly fluctuates depending on weather conditions, occupancy rate, and internal heat gains. Proper control of part-load operation can significantly affect energy use. Most boilers in medium-to-large commercial fa...

In order to improve the efficiency and rate of heat transfer in heat exchangers, various techniques such as increasing the heat transfer coefficient are proposed. This study is devoted to the investigation of heat transfer coefficient variations due to the addition of CuO, TiO2 and CuO/TiO2 nanoparticles into a shell and tube heat exchanger. CuO/TiO2 nanocomposite was synthesized using mechanic...

Oxide scale thickness measurements are used in assessing the life of different components operating at high temperature environment. Such measurements provide an approximation for the temperature inside components such as reheater and superheater tubes. A number of failures were encountered in one of the boilers in one of Kuwaiti power plants. These failure were mainly in the first row of the p...

Cement production is an energy-intensive process, so that the cement industry occupies a top position among other energy-consuming industries. Among the equipment used in cement industries, boilers are one of the energy-consuming equipment. Boilers are among the common heating equipment in industrial, commercial, and institutional facilities. In this paper, the performance of thermal oil bo...

in order to examine the laminar convective heat transfer of nanofluid, experiments carried out using silver-oil nanofluid in a concentric annulus with outer constant heat flux as boundary condition. silver-oil nanofluid prepared by electrical explosion of wire technique and observed no nanoparticles agglomeration during nanofluid preparation process and carried out experiments. the average size...

In this chapter, we illustrate benefits of thinking in terms of thread management techniques when using a centralized scheduler model along with interoperability of MPI and PThreads. This is facilitated through an exploration of thread placement strategies for an algorithm modeling radiative heat transfer with special attention to the 61 core. This algorithm plays a key role within the Uintah C...

Understanding nucleate pool boiling heat transfer and, in particular the accurate prediction of conditions that can lead to critical flux, is utmost importance many industries. Due safety issues related nuclear power plants, and for efficient operation units including fossil fuel boilers, fusion reactors, electronic chips, etc., it important understand this kind transfer. In paper, a comprehens...
