Furnace Facts: Atmospheric vs. Sealed Furnaces

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.

Buying a High-Efficiency Furnace - HomeTips

So, if your gas or oil-burning furnace was installed before 1992, you're probably sending 30 percent or more of your energy dollars up the furnace flue, and, by the way, pumping up to 4 tons of carbon dioxide, the "greenhouse gas," into the atmosphere each year.

Reducing atmosphere - Wikipedia

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.

Make Your Atmosphere Furnace Work for You: Tips of the Trade

A uniform temperature is one of the first, and most essential, steps for ensuring parts emerge with an ideal carburizing depth - and thus higher quality. In efficient batch atmosphere furnaces, such as the Ipsen ATLAS, temperature uniformity of at least ±13 ○F (±7 ○C) is maintained in the heat chamber.

Furnace atmospheres 1 Gas Carburizing and Carbonitriding

There is a carburizing gas atmosphere in the furnace. When the charge has reached the carburizing temperature, the effective trans-fer of carbon from gas to steel surface begins. Carburizing is allowed to proceed until the desired depth of penetration is reached. The charge is then moved from the furnace chamber to a cooling chamber, which

Heat-Treating and Metal Finishing Analyzers | Nova 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.

Does a Gas Furnace Dry Out the Air in Your Home?

Jan 16, 2014 · A sealed combustion furnace does essentially the same thing as the atmospheric combustion furnace sitting in unconditioned space. It's pulling combustion air from outdoors and sending the exhaust gases back outdoors, so it's only adding heat to your indoor air, not exchanging any of it with outdoor air.
