我厂是一个20多年的老厂,有轮窑三座.其中20门轮窑一座,自建成投产以来,一直使用12号离心式风机,配动力30kW,由于电耗高,加上1989年市场疲软,红砖利润只够交电费,无奈只好将20门轮窑暂停焙烧.1993年我们地区市场行情看好,加之我厂又扩大半成品生产量,这样原有的两座轮窑焙烧跟不上,为了加大成品产量,厂长晏桂芝决定再烧一把火,启用停了几年的20门轮窑.但怎样降低能耗,提高产量,由笔者建议使用《砖瓦》杂志社推广的ZFJ型节能引风机,当时有不少人持怀疑态度,说我们原用的风机动力是30kW,如果现在换上一个4kW的风机
Our factory is an old factory for more than 20 years. There are three wheel kiln, 20 of which are wheel kiln. Since the completion of production, we have been using No. 12 centrifugal fan, with power 30kW, due to high power consumption, plus the market in 1989 Weak, red brick profit is only enough to pay electricity, but unfortunately had to suspend the 20-wheel kiln roasting. In 1993 our market conditions are optimistic, coupled with our factory also expanded the semi-finished product production, so that the original two-seat wheel kiln roasting can not keep up, In order to increase the output of the finished product, the director Gui Guizhi decided to burn another batch of fire, which enabled the 20 wheel kiln to be stopped for several years. However, how to reduce the energy consumption and increase the output is recommended by the author to use the ZFJ type popularized by the “Zine” magazine. Energy-saving draft fans, many people at the time were skeptical, saying that we used the original fan power is 30kW, if you replace a 4kW fan
