The purpose of this research was to determine the effectiveness of using corn burning heating appliances as an alternative to more traditional natural gas or electric heat. Two models of different sizes and outputs were purchased for the test. The appliances were operated through the winter and into the spring to evaluation their performance. The equipment was operated following the manufacture...

The slagging and fouling characteristics of the heat recovery steam generator (HRSG) for ferrosilicon electric furnaces are discussed in this paper. Three ash samples were taken from the HRSG of a ferrosilicon furnace in Ningxia Province, China, which suffered from serious slagging and fouling. X-ray fluorescence (XRF), X-ray powder diffraction (XRD) and scanning electron microscope (SEM) were ...

This paper present the results obtained by simulation for the functioning regime improvement of an UHP Electric Arc Furnace. Because the nonlinearity of the electric arc the EAF functioning regime are perturbed from three causes: the current harmonics, the reactive power and the unbalanced load. In this paper there are study the possibilities of harmonics filtering and compensate the reactive p...

The paper describes the issues associated with waste generated during steel production and processing, in particular dust from electric arc furnaces (EAF). An effective solution for disposal of such is its involvement processing to obtain valuable products. This studies physical chemical properties EAF produced smelting metallized pellets captured by gas cleaning system steel-smelting shop at O...

The purpose of this study was to identify and assess dust exposure in Electrical Arc Furnaces for steel manufacturing. The major concern of steel making processes is dust generation and accumulation. The scope of this research paper focuses on different ways to improve current controls and make recommendations. In order to achieve the purpose, various goals were developed to identify the extent...

This paper presents a new application of a fractional order control system which controls the input energy to a three phase electric arc furnace. Graphite electrodes are used to convert electrical energy into heat via phase electric arcs. Constant arc length is desirable as it implies steady energy transfer from the graphite electrodes to the metallic charge in the furnace bath. With the charge...

The world is changing, and consequently so are policies on the use of natural resources. One most convenient ways to reduce consumption aggregates in production more sustainable construction materials recovered industrial by-products. In this study, concretes designed using siderurgical from electric arc furnaces, taking advantage their high density them as radiation shielding concrete. To veri...

furnace division is one of the most polluted divisions ever known in the steel industry associated with several environmental pollutions. this study attempted to choose optimally, a pollution control system for dust emission from steel furnaces with the green and environmentally friendly approach. three electric smelting furnaces with 3, 6 and 12-ton output capacity were selected. the level of ...
