摘要
介绍欧洲冷凝式燃气采暖热水炉的基本结构和燃气-空气比例调节的两种控制技术,探讨预混系统核心配件风机、文丘里混合器、燃气-空气比例调节阀的特点。对比分析半球型预混燃烧器和圆筒型预混燃烧器的特点,以及不锈钢换热器和铸硅铝合金换热器的优缺点。
The basic structure of European condensing type gas-fired heating hot water boiler and two kinds of gas-air ratio control technologies are introduced. The characteristics of core parts in premixed system including fan, Venturi tube and gas-air ratio control valve are discussed. The characteristics of semi-spherical premixed burner and cylinder type premixed burner as well as the advantages and disad- vantages of stainless steel heat exchanger and silicon a luminum alloy heat exchanger are comparatively analyzed.
