This paper presents a practical application of fuzzy logic to the temperature control of glass melting furnace for television picture tube. Because of the complexity and nonlinearity, temperature control of glass melting furnace is still delegated to human operators. Though the overall characteristics of glass melting furnace are complex and nonlinear, one part of the furnace characteristics ca...

Introduction Fast, efficient batch melting using the modern induction furnace can improve operating flexibility and production yield, as well as reduce the cost of environmental protection. The compelling advantages of induction batch melting have encouraged foundries to change the way they handle their melting operations. Among the chief advantages is cost. The operational cost of a typical in...

Developments of large scale and high-purity generation technique of single-walled carbon nanotubes (SWNTs) [1] are desired for the practical applications of this fascinating new material. In addition to previously known laser-furnace [2] and arc-discharge [3] techniques, catalytic chemical vapor deposition (CCVD) methods [4] have been developed for the possible larger amount production with low...

In order to cope with the demand for deep peak regulation of high-parameter coal-fired units, this paper uses numerical simulation methods systematically explore influence different secondary wind oxygen enrichment concentrations on combustion performance and characteristics singlefurnace double-cut round boilers during low-load operation, so as provide theoretical support actual operation powe...

Most of the iron in the world is produced using a blast furnace process, which has iron ore (iron oxides) and coke as its raw materials. When pellets are used in a blast furnace, the iron burden material is charged in the form of pellets and fine, iron-rich by-products are charged typically in the form of cold-bonded briquettes at the top of the blast furnace. Coke is the primary fuel and reduc...

Gas permeability in a blast furnace is directly influenced by the burden profile, which is the result of the charging angle collocation. An obviously increment in both iron-making productivity and furnace campaign life will be observed in a high heat utilization furnace with uniform gas permeability. An online burden profile measuring device without gas leakage risks and heavy maintaining load ...

A process simulation model was constructed for a 2 ton/hr incinerator. The simulation model was designed to provide system performance parameters according to various operating conditions. In accommodating the wide variation of quality and composition of input wastes, the plant operating parameters such as amount of excess air, preheated air temperature, waste feed rate and primary air distribu...

The current research studies the coupled combustion inside furnace and steam generation radiant convection tubes through a typical Once-Through Steam Generator (OTSG). A 3-D CFD model coupling two-phase flow was developed to entire system of OTSG. Once simulation converged, results were compared field data showing convincing agreement. analysis provides detailed behavior chamber stack, as well ...

In this paper is presented the analysis of the dynamics flow gas and the temperature distribution into a burning chamber with two identical burners on methan as result of heat density variation of one of them. Key-Words: methan combustion, burner, Finite Element Method, FLUENT.
