常用的工业炉窑主要有以下几大类:熔炼炉、熔化炉、加热炉、热处理炉、熔煅烧炉(窑)、电弧炉、感应炉(高温冶炼)、炼焦炉、焚烧炉、其他工业炉窑。

      工业窑炉按供热方式分为两类:一类是火焰窑炉(或称燃料窑炉），用固体（常用的燃料有：煤炭、生物质）、液体（重油、柴油、工业费油等）或气体燃料（天然气、液化气等）在窑炉内的燃烧热量对工件进行加热;*类是电窑炉，在窑炉内将电能转化为热量进行加热。

      Commonly used industrial furnaces mainly include the following categories: melting furnace, melting furnace, heating furnace, heat treatment furnace, calcining furnace (kiln), electric arc furnace, induction furnace (high temperature smelting), coke oven, incinerator, other industrial furnaces.

      Industrial kiln is divided into two categories according to the heating method: one is the flame kiln (or fuel kiln), with solid (commonly used fuels: coal, biomass), liquid (heavy oil, diesel, industrial oil, etc.) or gas fuel (natural gas, liquefied gas, etc.) in the kiln combustion heat to the workpiece heating; The second type is the electric kiln, in the kiln will be converted into heat for heating.
