目前全国不少中小化工企业利用柴油加热釜或罐,及其它用热设备。因为利用柴油加热,造价低,加热速度快,用油量小,一般用量为60～200 kg/小时。然而,有很多企业忽视了柴油燃烧热效率,因此大多数企业的柴油炉热效率只在20～30％,造成很大浪费,同时也给工人造成恶劣的工作环境。我们作了大量的调查,分析出柴油加热效率低的原因。 At present, many small and medium-sized chemical enterprises in the country use diesel heating kettles or cans and other heat-using equipment. Because of the use of diesel heating, low cost, fast heating, fuel consumption is small, the general amount of 60 ~ 200 kg / hour. However, many enterprises ignore the thermal efficiency of diesel combustion. As a result, most enterprises have a thermal efficiency of only 20-30%, which causes great waste and brings about harsh working conditions for workers. We made a lot of investigation, analysis of the reasons for the low efficiency of diesel heating.
