The following tables give the properties of gaseous, liquid and solid fuels used in furnaces. Gross calorific value includes the heat released by the condensation and cooling of combustion products, and the combustion air/fuel ratio is the stoichiometric value based on theoretically perfect combustion (see Combustion).In practice, excess air is required to ensure complete combustion.

Material for Fire Tube - Boiler and Pressure Vessel

2006-10-3 · These fire tubes are conected to a burner at one end, which delivers a 2.5m long flame with 750mm in diam, 1.6E6 Kcal/h and which has 2000°C at its hotest point (inside feather). For protecting the fire tubes from the flame there is another inside tube (length= 3m) made of Incoloy or Inconel. I'm wondering why do they use this material??
