Abstract: Furnace Boiler is a part and parcel of a steaming kettle (boiler) of type Scotch, because forming condense very depend on size measure ( wide of a hot surface) from Furnace Boiler, besides above the mentioned that maximum heat formed at the time combustion of fuel became the Furnace Boiler. To determine type and factors of a cause he happening of failure at a wall of Furnace Boiler from a steaming kettle of type of Scotch in factory taste this in the form of deformation of plastics at tabletop aiming to in till break. Type of examination performed within this research cover: visual perception, measurement of thick dimension of wall, fractography, metallography, hardness, tensile strength and analyze chemical composition of material Furnace Boiler and crust irrigate and also the hot simulation to material of Furnace Boiler. The case of a failed Scotch boiler fire cylinder at this plant that broke. This failure can be categorized into the type of failure due to usage (service). Steam boiler fire cylinder is one of the most important parts in producing steam for the process. In the process of usage, a failure occurred in the form of a rupture. In this case the inner fire cylinder wall (the side of the fire) is directly related to the high temperature (flame core) which, by way of the beam (radiation), heat moves to the outer cylinder wall of the fire (the water side). This fire cylinder in its operating conditions receives pressure from outside in the form of water vapor pressure. Pursuant to above perception result, seen by that breaking Furnace Boiler because of some factor: The happening of corrosion at waterside Furnace Boiler surface which causing decrease thick at the cylinder wall. So that, this area corrosion unable to again accept pressure work boiler and happen by overheating causing substance mechanic denaturing, so that happened by the permanent deformation (plastic deformation).
Keywords: Furnace, Failure, Plastic deformation, Overheat, corrosion.
