Inshot burners have become the dominant burner in North American residential gas furnaces, according to the American Gas Association. The burners have a single port, and fire into a pipelike heat exchanger. They differ markedly from older designs that had multiple burner ports with two-part heat exchangers, known as clamshells. Inshot burners have resulted in smaller furnace cabinets, a handy feature when remodeling a basement.  4, fiche 3, Anglais, - inshot%20burner

Modern furnaces make use of four different types of main gas burners. These burners are : 1) drilled port; 2) slotted port; 3) ribbon; 4) inshot.... usually the drilled pot burner is made of cast iron. The others are made by forming steel into the desired shape.... The burner head is the top part of the burner. It is here that the ports are placed that determine the type of burners(drilled port, slotted port, ribbon, or inshot).... The burners parts are openings that release the gas and air mixture into the combustion chamber.  5, fiche 3, Anglais, - inshot%20burner

A floating flame is an indication that there is a lack of secondary air to the flame. In severe cases, the flame will leave the burner and have the appearance of a floating cloud. Again, the intermediate products of combustion are apt to escape from place to place wherever sufficient air for combustion may be found. This flame is sometimes hard to detect because, as the door to the equipment is opened sufficient air will be admitted to allow the flame to rest on the burner properly. However, the obnoxious odor of aldehydes may still be detected. Another possible cause of this flame is an improperly operating vent system. If the products of combustion cannot escape, fresh air cannot reach the flame  1, fiche 5, Anglais, - floating%20flame

Record number: 5, Textual support number: 2 CONT

When a flame raises off the burner it is important to determine if it is a "lifting flame" or a "floating flame" :"Lifting Flames" rise from the ports to burn some distance above the ports. In some cases these flames will drop back to the port and lift again intermittently. They are caused by too much primary air. Decreasing the shutter opening will stop lifting flames. "Floating Flames" are long and lazy looking, poorly defined, quiet flames which roll around the combustion chamber sometimes completely off the ports. Floating flames result from too little secondary or "make up" air. Lack of secondary air can be caused by incorrect venting, clogged flueways, blocked secondary air inlet openings, or lack of natural room makeup air to the oven.  2, fiche 5, Anglais, - floating%20flame

Record number: 10, Textual support number: 1 CONT

In the past, it seems that burners were almost an afterthought in port design-furnace designers looked only at how to match burner and combustion air velocities. However it was during this decade that operators realized that they could reduce NO_x rates significantly by controlling the mixing rates of fuel and air. By delaying the mixing of fuel and air, operators then found that flame luminosity could be enhanced-thereby increasing efficiencies and reducing pollution. The delayed mixing would lead to increased cracking of the gas--which increased the radiative effect of the flames.  3, fiche 10, Anglais, - delayed%20mixing
