煤气流动粒子炉(a gas-fired flui dized bed furnace)是一种较为新型的金属热处理妒。它是以煤气为燃料,以煤气和空气的燃烧产物为流化介质、使床层沸腾,达到加热和对金属进行热处理的目的。一般认为这种炉子可以取代或部分取代现有的盐浴炉。本文使用几种不同的粒子进行煤气流动粒子炉的热态实验研究,对于认识煤 A gas-fired flui dized bed furnace is a relatively new type of metal heat treatment jealousy. It is based on gas as fuel, gas and air combustion products as fluidized medium, so that the bed boiling to achieve the purpose of heating and metal heat treatment. It is generally accepted that such furnaces can replace or partially replace existing salt bath furnaces. In this paper, several different particles were used to study the thermal state of gas flow particle furnace,
