In this study, the ecological parameters of the effluent obtained from dyeing of scoured and mercerised organic cotton single jersey fabrics with textile reactive dyes adopting exhaust dyeing method was investigated. The dyes used include regular (Navacron H and FN) reactive dyes and low impact (Remazol and Levafix) reactive dyes along with inorganic salt (sodium sulphate) and biosalt (trisodiu...

Abstract We report the outcomes of a study into influence alkali concentration on expansion induced by alkali–silica reaction (ASR), deleterious that causes cracking and durability loss in concrete structures. assessed effect mortar bar using modified form AS1141.60.1, accelerated test (AMBT). Mortar prisms were prepared with reactive aggregate immersed solutions varying concentrations (from 0....

A non-linear model has been developed for a gas-fired furnace in which oil is heated. The model is applicable from minimum to maximum heat load of the furnace. The dynamics of the model have been compared to experimental results, which were obtained for a pilot-scale furnace. They are in good agreement. A cascade control with feed-forward action has been compared to single feed-back control. Pr...

Combining the transformation project of certain strip steel rolling production line, the techniques process of walking beam heating furnace was elaborated in this paper. The practical application of LOS-T18-2ZC1 laser detector was elaborated. The network communication model of walking beam heating furnace control system was designed. The realization method of production process automation contr...

Induction heating furnaces are employed for vacuum distillation process to recover and consolidate heavy metals after electrorefining operation. Induction heating furnaces of suitable heating rates are required to be developed for this purpose. Hence it is planned to set up a mock-up induction furnace which will simulate the conditions to be realized in actual induction heated vacuum distillati...

Blast furnace gas is the byproduct of smelting steel production process, and is the important secondary energy source. It is can be used as fuel for engines to generate electricity for most middle and small steel enterprises. In order to understand the combustion mechanism and provide the basis for the design of blast furnace gas engine,premixed laminar combustion experiments of the blast furna...

This paper deals with a novel interactive approach of Artificial Neural Network (ANN) as an optimization tool for optimizing process parameters of rotary furnace. This approach solves a very challenging problem in the area of rotary furnace i. e. selection of optimal process parameters for producing homogenous quality castings. Rotary furnace involves several critical parameters like flame temp...

AIM To describe a new toxic inhalation syndrome in blast furnace workers. METHODS Fourteen workers developed acute respiratory symptoms shortly after exposure to "air blast" from blast furnace tuyeres. These included chest tightness, dyspnoea, rigors, and diaphoresis. Chest radiographs showed pulmonary infiltrates, and lung function a restrictive abnormality. This report includes a descriptio...

This paper presents the application of DSTATCOM in a distribution network with induction furnace load. Induction furnace is one of the common types of load used in industries like the steel industry. The problem with the induction furnace load is the generation of appreciable amount of harmonic distortion. This distortion results due to the design and operation of the induction furnace. This ha...

Optimisation and improved control of the annealing furnace on a continuous galvanising line was investigated by the construction of a series of mathematical models to predict furnace and strip temperature and strip recrystallisation under both steady and transient states. A modelling approach is followed due to the very poor measurability of temperatures inside the furnace, affected by strong r...
