强制通风油燃器

[中文适用范围]： 本国际标准规定了自动强制通风燃油燃烧器的构造和操作的术语、试验程序和一般要求，该燃烧器所供燃料在 20°C 或更高温度下在燃烧器入口处的粘度为 1.6 mm2/s (cSt) 至 6 mm2/s (cSt)，沸腾石油符合 ISO 8217 规定的第一残液，以及相关的控制和安全装置的配备。 本标准适用于以下设备： a) 装有助燃风扇并按第 5 章所述装备的自动燃油燃烧器（以下称为“燃烧器”），旨在用于不同类型的器具并使用燃油； b) 带有单个燃烧室的单个燃烧器，当这种燃烧器安装在单个器具上时，相关器具标准的要求也适用； c) 仅使用燃油运行时的单燃料和双燃料燃烧器； d) 设计用于同时使用气体和液体燃料的双燃料燃烧器的油功能，对于气体和液体燃料，ISO 22967 的要求也适用。它不适用于直接燃烧工艺中使用的燃烧器，无论是具有定义的燃烧室应用，还是燃烧室壁面温度高于 750°C 或传热介质温度高于 500°C 的情况。 [外文原描述]： ISO 22968:2010 specifies the terminology, test procedures and general requirements for the construction and operation of automatic forced draught oil burners supplied with a fuel having a viscosity at the burner inlet of 1,6 mm 2 /s (cSt) to 6 mm 2 /s (cSt) at 20 °C or higher, boiling petroleum in accordance with ISO 8217-based first raffinates, and the provision of related control and safety devices. It is applicable to automatic oil burners fitted with a combustion air fan, equipped as described therein, and intended for use in appliances of different types and operated with fuel oils, single burners with a single combustion chamber, single‑fuel and dual‑fuel burners when operating only on oil, and the oil function of dual-fuel burners designed for simultaneous operation on gaseous and liquid fuels (for the former operation, see also ISO 22967). It is not applicable to burners used in direct fired processes either with defined combustion chamber applications or where the combustion chamber wall surface temperature is greater than 750 °C or the heat transfer medium temperature is greater than 500 °C.
