前言作为煅烧石灰的热工设备,从过去的倒焰窑进展成现代的石灰竖窑,这是热工技术的进步。世界上先进国家都广泛地采用竖窑煅烧石灰,我国使用气烧石灰竖窑代替燃焦混烧窑业已有二十多年历史。生产经验表明:小竖窑(容积20米~3以下)煅烧石灰比大窑产量(单位容积产量,吨/米~3·天)高,质量为好。一般小窑容积利用系数高达1.2～1.5吨/米~3·天以上,几乎无欠烧,而 Preface As a thermal equipment for calcining lime, it has evolved from the past, a down-fired kiln, into a modern lime-shale kiln, which is a thermal engineering advance. The world’s advanced countries are widely used shaft kiln calcined lime, China’s use of gas-fired lime shaft kiln instead of burning coke kiln industry has more than 20 years of history. Production experience shows that: small shaft kiln (volume 20 meters to 3 below) calcined lime production than the kiln (volume per unit volume, t / m ~ 3 days) high, good quality. Generally small kiln volume utilization factor of up to 1.2 ~ 1.5 tons / m ~ 3 days or more, almost no owe burn, and
