CO and CO2 Control of Endothermic Gas in Heat Treatment Furnaces

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.

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.

US4586899A - Gas atmosphere heating furnace - Google Patents

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.

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.

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

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.

Heat Treat Furnaces with protective atmosphere - Keith Company

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.

How to Vent a Gas Furnace | DoItYourself.com

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.

3 Problems with Atmospheric Combustion Inside the Building

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.
