5000KW微机控制直接式原油加热炉

加热炉是长输管道和油田生产中广泛使用的加热设备，要求热效率高、安全可靠、适应性广、性能稳定、操作简便。综述了加热炉技术的发展状况，介绍了５０００ＫＷ微机控制直接式原油加热炉的性能，特点和研制，测试、运行结果。该加热记已正式投入生产运行一年多，与相同热负荷的热煤间接加热，造价为后者的６０％－７０％，占地面积也大为减少，以濮临线输油量计算，年节约燃料油费用人民币１００万元，１９９３年１２月通过了中国石

5 000 kW Direct Heating Boiler Controlled by a Computer

Boilers are a kind of widely used heating equipment in long distance pipelines and oil fields, having such characteristics as high heating efficiency, safety and reliability, wide applicability, stable performance and being convenient in operation.The development of boiler tachnique is summerized in the paper with the introduction of a 5 000 kW controlled by a computer, its performance, characteristics and the results of research and production, tests and operation. This boilor has been in use for a year or so, 60%-70% of the cost of indirect heating system of diathermic oil which shares the same heat load, but much smaller in dimension. Taking the flowrate parameters of Pu-Lin Pipeline for calculation, it can save 1 million yuan (RMB) for the fuel consumed annually.It was authenficated as one of the scientific achievements by CNPC in Dec, 1993. The Authentics Certificate says: "Computer controlled direct heating boilers are of light package structure, with the lining of folded pads of aluminum silicate fibre which is fireproof, and the neumatic atomizing burner with the ait and oil mixed outside of it, optiomizad by computers for burning control of double crossing and double direction range control system, etc are used in a compressive way and make it possible for the average heat efficiency get to 91%. According to the latest documentation published, it is the first applicationin in China, close to up-to-date world level.
