The furnace atmosphere can be monitored by analyzing the CO and CO₂ gas concentrations, and this gives an accurate reading of the composition of endothermic gas being delivered to the furnace. This can be done by infrared sensors, because they are easy to operate and provide quick readings, as well as producing easily understandable results.
We know, its sounds like something that supposed to be launched into the upper atmosphere. But an atmospheric furnace is simply a furnace that draws on air inside a home in order to mix with the natural gas from the burner and allow combustion to occur. A grill on the furnace pulls in this air for the combustion process.
In a continuous heating furnace, particularly in a preheating chamber thereof, forced heat convections of an atmosphere gas are produced to heat articles rapidly. The convections which circulate transversely to a longitudinal axis of the furnace, retard an axial flow of the atmosphere gas.
Gas analyzers can be used for monitoring atmosphere gases and flue gases in steel finishing and heat treating furnaces in steel mills. After molten steel is produced by the melt shop, it usually then requires shaping and finishing in rolling mills, bar mills, blooming mills, wire mills, etc. Gas analysis in these mills are generally classified as being either flue gases or atmosphere gases.
vent and the atmosphere around it. The combustion air entering the furnace is at atmospheric pressure which, at sea level, is about 14.7 PSIA (Pounds to the Square Inch Absolute pressure). The hot flue-gases rising out of the furnace are less dense, creating a pressure drop within the heat exchanger. This "gap" is continually being filled
In metal processing, a reducing atmosphere is used in annealing ovens for relaxation of metal stresses without corroding the metal. A non oxidizing gas, usually nitrogen or argon, is typically used as a carrier gas so that diluted amounts of reducing gases may be used.
in an atmosphere of air, inert gases (nitrogen, argon, hydrogen), active atmospheres for carburizing, nitriding and other active diffusion atmospheres, in high temperature systems up to 1300°C, low vacuum in retort furnaces up to 10-2 mbar.
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.
The "furnace atmosphere" means a gas to be filled and heated in the furnace by which the product (workpiece) is indirectly heat-treated. The atmosphere gases include air, inert gases, hydrogen (reducing gas), and others, which are heated up to 1000 - 2500℃ depending on the properties of the workpiece and purpose of the heat treatment.
Cycling of inert gas atmosphere through water cooled heat exchanger This option is available on all HTK vacuum chamber furnaces with capacities greater than 25 litres. When fitted, the gas is cycled out of the furnace into a heat exchanger and pushed back after cooling down into the furnace chamber.
KSL1700X-H2 is CE certified box furnace designed for material synthesis under hydrogen or inert gas atmosphere up to 1700 ºC. The furnace consists of high quality alumina fiber bricks and Mo alloy heating elements with a heating chamber of 8"x 8"x12", as well as a vacuum-sealed steel case with water cooling jacket and automatic H2 burning system.

Step 1 - Identify Your Vent. A direct vent will directly throw all the air into the atmosphere. Most old gas furnaces use such a mechanism, while modern furnaces use the B-pipes. These pipes are not only environmentally friendly for residential use, but also authorized for use by regulatory bodies and insurance companies.
The two atmospheric combustion appliances of most concern are furnaces and water heaters. (Fireplaces deserve their own article, so I'll leave them for later.) If your atmospheric combustion furnace or water heater is in a vented crawl space or a vented attic, it's outside the building envelope and is less likely to create health and safety problems inside the house.
A retort furnace is a furnace wherein a closed vessel of metal or ceramic is utilized in a batch process. Retorts allow accurate and efficient control of the work space atmosphere and provide low atmosphere usage due to the closed nature of the system.
• Conventional Furnace (Atmosphere Furnace): conventional carburizing is an atmosphere controlled process with control of the. carbon potential. • Low Pressure Carburizing Furnace (LPC): low pressure carburizing is running without any oxygen and with injections of. carburizing gas (acetylene for example).
Gas carburizing in batch furnaces is a widely adapted procedure used for surface hardening, yet it faces some challenges in performance reliability and process control. The quality of the
