英国 Steetley 耐火材料公司在一座间歇式窑上安装了一台 Eurotherm 211型程序控制器,获得的经济效益是使燃料消耗降低了25%,生产周期缩短了90小时。因此该公司已定购了第二台仪器,准备安装在另一座窑上,其他一些窑也在考虑应用。该程序控制器所控制的间歇式窑的生产能力为90吨,该窑用于生产厚度为38毫米以上、铸锭坑用耐火材料。窑的加热是用天然气通过高速燃烧器,高速燃烧器由一个 U型导管将热空气射流送入窑体,并从窑底部排出。
Steetley Refractories UK installed a Eurotherm 211 process controller on a batch kiln, resulting in a cost savings of 25% in fuel consumption and 90 hours in production cycle time. So the company has ordered a second instrument to be installed in another kiln, and some other kilns are also considering applications. The program-controlled batch kiln has a production capacity of 90 tons and is used for the production of refractories for ingots and pits with a thickness of 38 mm or more. The kiln is heated with natural gas through a high-speed burner. A high-speed burner sends hot air jets from a high-speed burner into the kiln and exits from the bottom of the kiln.
