Gas-Fired Chamber Furnaces up to 1300 °C FURNA PECKA ZA VISOKA TEMPERATURA

Certain firing or sintering processes require a gas-fired chamber furnace. Short heating times due to the high power are a convincing argument. The chamber furnaces with powerful gas burners cover a wide variety of these processes. In the basic version the burners are manually ignited once at the start of the process. The automatic control system then takes over control of the temperature curve. At program end, the burners are automatically switched off. Depending on the process, the furnaces can be equipped with automatically controlled fan burners and safety technology for debinding. Especially in case of larger binder concentrations, gas furnaces have the advantage that the exhaust quantity can be significantly reduced as the binders are burnt off in the furnace, providing for downsizing of the exhaust cleaning.

• Tmax 1300  °C
• Powerful, atmospheric burners for operation with liquified gas or natural gas
• Special positioning of the gas burners with flame guide top-down provides for good temperature uniformity
• Fully automatic temperature control
• Gas fittings with flame control and safety valve in accordance with DVGW (German Technical and Scientific Association for Gas and Water)
• Multi-layer, reduction-proof insulation with light-weight refractory bricks and special back-up insulation result in low gas consumption
• Self-supporting and rugged ceiling, bricks laid in arched construction or as fiber insulation
• Dual shell housing, side panels made of stainless steel (NB 300), for low outside temperatures
• Solid, dual shell door
• Exhaust hood with 150 mm (NB 300) and 00 mm (NB 400, NB 600) diameter connection
• Over-temperature limiter with manual reset for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load
