Safety Concept for Debinding Debinding of technical ceramics is a critical process due to the released hydrocarbons which subject to the corresponding concentration can cause a formation of an ignitable mixture inside the furnace. Depending on the process and the quantity of binder, Nabertherm offers tailored passive and active safety packages to ensure a safe operation of the furnace. 1. Debinding in an Electrically Heated Furnace For debinding in air with electric heating Nabertherm offers various debinding packages tailored to the individual process requirements. All debinding packages...

DB100 Debinding Package for Production Furnaces with Radiation Heating The DB100 debinding package is the basic option for safe debinding in furnaces with radiation heating. The furnace is equipped with a fresh air fan and a fresh air preheater. The fresh air fan is pre-set in the factory for the minimum volume of fresh air required for the debinding process. The furnace is operated with overpressure during the debinding process. Exhaust air and exhaust gas are blown out via an outlet equipped with a motor driven flap into an exhaust hood with exhaust interruption. This is the interface to...

Safety Concept for Debinding The main differences and/or advantages between the DB100 and DB200 debinding packages are: Automatic control of the exhaust gas fan in relation to the selected volume of fresh air. This is beneficial for temperature management (uniform temperature) and an adaptable extraction of the exhaust gas volumes. Reduced odors and condensation in the exhaust gas piping. Perforated tubes in the furnace chamber for even distribution of preheated fresh air throughout the horizontal charging levels Exhaust gas system can be dimensioned smaller, since no cold air is added via...

IDB Safety Concept in Retort Furnaces for Debinding under Non-Flammable Protective Gases or for Pyrolysis Processes The retort furnaces in the NR(A) and SR(A) series are ideal for debinding under non-flammable protective gases or for pyrolysis processes. With the IDB option, the furnace chamber is flushed with protective gases. Exhaust gases are incinerated in an exhaust gas torch. The flushing and the torch function are monitored to ensure safe operation. ■ Process management under monitored overpressure of 35 mbar relative ■ Failsafe Siemens PLC and graphic touch panel to enter data ■...

I. BO Safety Concept for Processes with High Organic Vaporization Rates The BO safety concept is recommended for processes with high vaporization dynamics that are difficult to control. Diluting the furnace atmosphere with air is not sufficient to guarantee non-ignitable mixtures in the furnace. Examples of this are processes with high binder amounts or rapid vaporization rates. This furnace concept is also suitable for processes in which the product is incinerated through ignition. Air is continuously added to the furnace atmosphere to ensure a constant surplus of air. If, despite of this,...

III. WAX Safety Concept for Electrically Heated Furnaces to Melt Out Wax below its Flashpoint Furnaces of the WAX series with the corresponding safety concept are suitable for dewaxing parts, e.g. ceramic molds, below the wax flashpoint. The melted wax is collected in a container underneath the furnace. This collection container is positioned in an airtight drawer which can be removed for emptying. The wax runs through a grid into a funnel-shaped drain in the base of the furnace. The drainage channel is heated to stop the wax hardening. The furnace program is started only when the set...

Safety Concept for other Processes where Organic Exhaust Gases Form V. Safety Concept EN 1539 (NFPA 86) to Dry Liquid Solvents in Ovens The safety technology of furnaces and dryers used for processes in which solvents or other flammable substances are released and vaporized relatively quickly is regulated throughout Europe in EN 1539 (or NFPA 86 in the USA) Typical applications are drying of mold varnish, surface coatings, and impregnating resins. Users include the chemical industry as well as many other areas, such as the automotive, electric, plastic processing and metalworking...
