介绍一种硫酸电加热炉

Introduction of a Electrical Heater for Sulphuric Acid Production

在硫酸电加热炉改造中，以０Ｃｒ２５Ａ１５铁铬铝合金丝取代原管式电加热元件，并采用可控硅自动控制加热温度。该电炉投资省，简单，可靠，高效，配置灵活。

OCr25A15 Kanthal alloy wire was used to replace the original tube electrical heating elements anda thyristor was used to control alltomatically thetemperature rise in the transformation of the electrical heater of a HZSO4 plant. The new heater was economical, simple, reliable, efficient and flexible indisposition.
