This can be achieved by injection of Nitrogen or Argon into the furnace chamber to create an inert (passive) atmosphere. Connecting Nitrogen directly to the inert gas inlet or have the flow activated through an event programmed in the temperature controller will achieve positive pressure in the heat treat chamber. For tool room shops, laboratory- or R&D environments, small benchtop furnaces with protective atmosphere control are an economic solution. A programmable event in the program
Furnaces with hydrogen atmospheres are used when a reducing and non-carbonizing atmosphere is needed; for example, in the heat treating of metals or powder ceramic processing. Nitrogen atmosphere are needed for the carbonization process of carbon fiber. We build Atmosphere heat treating furnaces with retorts, muffles and cold walls.
the furnace atmosphere. If an adequate flow rate of high purity gases is being used and if the supply system is free of leaks, the trace oxygen level of a typical retort-lined industrial furnace will generally be below 10 to 15 ppm 02 in all areas except the entrance and exit region. The water vapor level (generally reported as dew point)
The atmospheres used can be nitrogen, argon, exothermic gas, endothermic gas, nitrogen-methanol, ammonia, dissociated ammonia, steam, or controlled mixtures of more than one gas. One common atmosphere furnace arrangement is the bell type, where the heating system is contained in a lifting box, or cylinder shaped shell, which is then sealed to a base holding the work load and containing the atmosphere seal.

Technological applications of pit furnaces
Nitrogen Generator for Sintering: The bonding of adjacent powder particle surfaces in a mass of metal powders or a compact, by heating. Sintering is typically performed in a furnace atmosphere consisting of Nitrogen/hydrogen, dissociated ammonia (or diluted dissociated ammonia), hydrogen, or vacuum.
When using nitrogen methanol in a furnace at the typical operating temperatures, the methanol immediately dissociates into carbon monoxide and hydrogen. When mixed, 33% methanol (CH 3 OH), 66% nitrogen, and endothermic equivalent atmosphere are formed in the furnace. When using sensors and when the base atmosphere in the furnace is under equilibrium conditions, these assumptions must be consistent, known, and repeatable.
Sep 12, 2012 · A team from Plymouth Tube, AE and Praxair laid out the steps for a successful and safe introduction of a hydrogen-nitrogen atmosphere during the restart of the annealing furnaces. A checklist was developed to guide the team though the construction phase, pre-start-up phase and the start-up phase of the atmosphere project.
The Industry's Best Atmosphere Control Nitrogen | Hydrogen | Forming Gas | Argon. BTU is the industry leader in atmosphere control for continuous furnaces. Excellent atmosphere purity is achieved through the use of BTU's patented gas barrier technology.

Features of nitrogen atmosphere furnace: (1).Heavy duty double layer with cooling fan to keep case temperature lower; (2).High purity alumina fiber for best energy saving; (3).PID automatic control via current limiting phase angle fired resistor,e.g.SCR (4).Power control with 30 segments
1200 Degree Laboratory Nitrogen Argon Atmosphere Muffle Furnace For Sintering Quenching Annealing. Laboratory Atmosphere furnace Application: It is designed for material synthesis under controlled inert gas atmoshphere up to 1100 ºC with better temperature uniformity. The furnace consists of high quality alumina fiber brick and
Modified atmosphere with metallic retorts in standard chamber furnaces For non-gas tight ovens and chamber furnaces the use of modified atmospheres is limited. By purging inert gas into the chamber via an optional gas inlet, the atmosphere within the oven and furnace will not reach low oxygen values.
furnace is at a temperature higher than 760°C. Both procedures require ignited pilots that remain lit in inert atmospheres stationed at both the charge and discharge ends of the furnace. When flame appears at both of these ends, the introduction of the flammable atmosphere is complete. It is also important to in-stall a full range of protective safety
