Abstract

Porous burners are known by their high efficiency and low polluting gases emissions. Their high efficiency is given by the great thermal radiation potential, whereas differently a normal burner, the process of combustion happens in the inner of the porous medium, which is compound by spheres of alumina, and the mix air-fuel goes through the preheating zone, potentializing the combustion. The burners are usually used in the industry, in the process of drying of paper and wood, plastic coating, food cooking and ambient heating. In this article, it was studied the behaviour of the flame in a porous radiant burner with alumina’s sphere of 1/2” and 1/4”, using LPG as fuel, compressed air as oxidizing agent and ceramic wool as thermal insulation. The burner was divided in three essential sections with a type K thermocouple in each one, which are: base, middle and top. The flame profile encountered was a floating one, however it is almost stable, presenting low variations of temperature and according to previously tests, less consuming of fuel.
使用1/2 "和1/4 "氧化铝球体的多孔辐射燃烧器的火焰轮廓
多孔燃烧器以其高效率和低污染气体排放而闻名。它们的高效率是由于巨大的热辐射势,而与普通燃烧器不同的是,燃烧过程发生在多孔介质的内部,这是由氧化铝球复合的,混合空气-燃料通过预热区,使燃烧成为潜在的。燃烧器通常用于工业中,纸张和木材的干燥,塑料涂层,食品烹饪和环境加热过程中。本文以液化石油气为燃料,压缩空气为氧化剂,陶瓷羊毛为绝热材料,研究了氧化铝球体为1/2 "和1/4 "的多孔辐射燃烧器中火焰的行为。燃烧器分为三个基本部分,每个部分都有一个K型热电偶,它们是:底部,中间和顶部。遇到的火焰轮廓是浮动的,但它几乎是稳定的,呈现低温度变化,根据以前的测试,燃料消耗较少。
