Implementation of convective heating in Companhia Siderúrgica Nacional Blast Furnace runners
(2013-01-21)
This paper describes the main characteristics and advantages of convective heating system for refractory lining, compared with conventional heating systems. In addition the main results obtained are presented with its ...
Thermal analysis of solar‑assisted heat pumps for swimming pool heating
(Springer, 2017-06)
The present work analyzes the technical feasibility of solar-assisted heat pumps for swimming pool heating in South Brazil. The methodology is based on computer simulations for four configurations of heating systems for ...
Methodology for DSC calibration in high heating rates
(2011-08-01)
Despite the large use of differential scanning calorimetry (DSC) technique in advanced polymer materials characterization, the new methodology called DSC in high heating rates was developed. The heating rate during ...
Analysis of reverse heat transfer for conventional and optimized lubri-cooling methods during tangential surface grinding of ABNT 1020 steel
(Fundação Gorceix, 2016-12-01)
Abstract A numerical thermal model was developed to evaluate the heat flux which is conducted to a rectangular workpiece of steel plate ABNT 1020, thus making it possible to compute the maximum temperature in the grinding ...
Kinetics of the Transesterification of Castor Oil with Maleic Anhydride Using Conventional and Microwave Heating
(Springer, 2012-01)
The transesterification of castor oil with maleic / anhydride was studied using conventional and microwave heating. Reactions were followed by measuring the acid value and the reaction products were characterized by FTIR ...
Physico-chemical of organo-functionalized magnesium phyllosilicate prepared by microwave heating
(Elsevier Science BvAmsterdamHolanda, 2014)
Densification of Mn-doped tin oxide films by conventional heating and microwave heating treatment
(2005-12-01)
Mn(II) doped SnO2 thin films used for shielding fluoride glasses against corrosion were investigated by x-ray absorption spectroscopy (EXAFS and XANE)S at the Sn and Mn K-edges. The effect of firing treatment on the ...
Analysis of aluminum plates under heating in electrical and natural gas furnaces
(Elsevier B.V.Elsevier B.V., 2000-10-01)
This paper analyzes the thermal storage characteristics of aluminum plates in furnaces during their heating for lamination under two sources of heat: an electrical resistance bank and a combustion process carried out with ...
