Developments in technology and the marketplace now make it possible for embedded systems to communicate in local Ethernet networks as well as on the Internet. Network communications can make an embedded system more powerful and easier to monitor and control. Ethernet solves the problem of remote communication with the embedded application. Challenges like application monitoring, control, diagno...

To evaluate the effects of industrial by-products materials on the performance of porous concrete for plant growth, this study investigated the physical, strength, and freeze/thaw resistances of porous concrete for plant growth, prepared by replacing cement with blast furnace slag powder at 60% by weight, and replacing natural stone aggregates with coarse blast furnace slag aggregates at rates ...

The objective of this study was to develop an integrated simulation model of an automatic blast furnace in a full-scale steelmaking factory. The integrated simulation model introduces a set of optimizing alternatives through sensitivity analysis. The simulation model is built by considering all major and detailed operations and interacting systems of the blast furnace workshop. The workshop is ...

Quench hardening is the process of strengthening and hardening ferrous metals and alloys by heating the material to a specific temperature to form austenite (austenitization), followed by rapid cooling (quenching) in water, brine or oil to introduce a hardened phase called martensite. The material is then often tempered to increase toughness, as it may decrease from the quench hardening process...

Accurate prediction of pollutant emissions from turbulent combustion around complex geometries is of great practical interest. Here, an industrial furnace with rich-burn/quick-quench/lean-burn combustion for NOx reduction is simulated. Large eddy simulation (LES) is employed as the simulation tool since it outperforms Reynolds-Averaged-Navier-Stokes (RANS) simulations in capturing large-scale u...

A numerical study on Nox emission from an industrial furnace utilizing high temperature air combustion (HTAC) technology was done. The basic concept of the regenerative burner including heating a diluting of fresh air by flue gas was implemented in a two-dimensional furnace model. Governing equations in conjunction with a turbulence model and an overall chemistry model were solved using an impl...

Abstract Traditional control instruments and DCS systems are limited by shortcomings such as single function, independent controlled elements, inability to close-loop on site, ineffective communication. Aiming at these problems, this paper proposes a kind of industrial furnace edge controller which has the functions acquisition, calculation, control, storage, output communication in one. The st...

ABSTRACT:A mathematical model for the performance prediction of an industrial glass furnace with six ports on each side was developed. This model comprises of two main sub-models for the combustion chamber and glass-melting tank. The first sub-model consists of the models for the combustion and the heat transfer model including, radiation, convection and conduction. The fuel combustion in a...
