1957年西德电力工业中燃油的比重只占12%,而1970年已上升到50%。1956年单只燃烧器热功率仅为5.0～7.0×10~6大卡/时(燃油量为500～700公斤/时)。这一年第一次制造了热功率为10.0×10~6大卡/时(燃油量为1000公斤/时)的油燃烧器,采用带有轴向和径向旋流叶片的扩散器。在当时,这种发展被认为是冒进的。从1956年以后液体和气体燃料燃烧器才开始大规模地发展。60年代前半期单只燃烧器热功率已经达到30×10~6大卡/时,后期提高到50×10~6大 In 1957, the share of fuel oil in the West German power industry only accounted for 12%, but in 1970 it had risen to 50%. 1956 single burner thermal power is only 5.0 ~ 7.0 × 10 ~ 6 kcal / hour (fuel quantity is 500 ~ 700 kg / h). This year, for the first time, oil burners with a thermal power of 10.0 × 10 ~ 6 kcal / h (with a fuel capacity of 1000 kg / h) were manufactured using a diffuser with axial and radial swirl vanes. At the time, this development was considered aggressive. Since 1956 liquid and gas fuel burners began to develop on a large scale. In the first half of the 1960s, the thermal power of single burner reached 30 × 10 ~ 6 kcal / h and increased to 50 × 10 ~ 6
