IPC: C21B5/00
Filed: 1978-04-27
Abstract: PURPOSE:To prevent explosion in reducing blow out of a blast furnace by opening the peep hole cover of a tuyere under the conditions of blast from the tuyere when a burden level reaches the tuyere and by stopping blast to automatically draw the air through the peep hole. CONSTITUTION:In reducing blow out of a blast furnace, blast form tuyere 4 is gradually reduced as burden 8 falls to allow the level of burden 8 to reach level 3 of tuyere 4.

Title: Operating method of blast furnace power plant
Inventor: KOMATSU SHIGERU
IPC: H02P9/00
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To obtain the optimum power-generation efficiency of a blast furnace power plant, by so computing its maintenance starting time-point as to maximize its average power- generation efficiency based on the approximate curve obtained from the transition of its power-generation efficiency and based on its necessary maintenance term, and by determining then its maintenance period or its maintenance starting time-point. SOLUTION: In this method, the maintenance starting time-point of a blast furnace power plant is so computed to determine the time-point or its maintenance period that its average power-generation efficiency is maximized based on the approximate curve obtained from the field-proven transition of its power-generation efficiency and based on its necessary maintenance term. In this case, the necessary maintenance term means the cleaning work term of its turbine blade which can be predicted previously from the past cleaning work thereof.  Also, since the maximum value of its average power-generation efficiency is obtained through dividing its total power-generation efficiency by one-cycle term, the definite integral of the foregoing approximate curve in a term is performed, and the integrated curve is differentiated by one-cycle term used as a time unit to obtain the inflection point thereof. As a result, the one-cycle term whereat its average power generation efficiency becomes maximum can be computed. Then, from the one-cycle term giving the maximum efficiency, the necessary maintenance term is subtracted to determine its maintenance period or its maintenance starting time-point and its optimum power-generation efficiency is obtained.
