Abstract
The purpose of this investigation is to know the fundamental knowledge of cupola operation, through surveying the relation between its construction or something else of cupola and the reactions in furnace, and also through surveying the effects of these factors upon the conditions of melting in furnace.
In order to know the type of air flow blown from the blast pipe and pressure drop in furnace, various surveys were made by using a simple cylinder and a midget cupola. And besides, consideration about air flow in furnace was made with applying fundamental equation which was established by inducing the Bernoulli's theorem into the Sobri Ergun's equation concerning to blast furnace and cupola :
ΔP=√Pe2+5.9×10-6{(1−ε)⁄ε3)}{(t−460)⁄520)}(Q0⁄Aα)H⁄DP −Pe
That proved to agree with the results of author's experiments.
