Natural Gas Burners and Burner Tubes - These natural gas burners control the gas as it enters the gas burner tubes. The gas burner tubes have little holes which control the amount of gas that exits the top of the gas burner tubes. The black pipe running out of the gas valve is the manifold.
Where the gas burner tubes are connected to the manifold are little precisely drilled holes inside of brass inserts. The precisely drilled holes are engineered specifically for natural gas. The size of the holes plus the pressure in the manifold determines how much natural gas enters the gas burner tubes.

Gas Furnace Facts - Gas Furnaces are the most used types of the heating appliance for our homes and businesses and modern gas furnaces range in efficiency ratings from 79% to 98%. Gas furnaces can either use propane or natural gas for fuel. That largely depends on whether natural gas is available at the location of the appliance.
Propane is used in rural areas and in urban areas where the natural gas pipeline infrastructure is not available. Natural gas is delivered via pipeline, while propane is delivered via trucks and pumped into tanks. Tanks locations are on the premises near the gas furnace. The gas furnace that utilizes the propane for fuel needs a fuel supply. Therefore, the proximity of the tank.

Gas Furnace Components | HVAC Heating Systems. Different types of gas furnaces are available for purchase today and the older models which were installed many years ago still in operation. The older models were typically atmospheric-type gas furnaces and used a lot of gas to produce heat, much of which went up the flue because efficiencies were low.
The standing pilot atmospheric type gas furnaces still exist today, but they are slowly going the way of the dinosaur as newer more efficient furnaces are replacing them. (more…)

Gas Fired Pool Heater
Gas Furnace Types come in a variety of sizes and can be used for different applications. Types of gas furnaces have different classifications. By and large, the most common gas furnaces use natural gas and utilize electronic ignition. Electronic ignition gas furnaces are slowly replacing the older style standing pilot furnaces where a pilot light remained lit all the time.
Now, with the newer modern electronic ignition, gas furnaces only use gas when there is an actual call for heat. That adds efficiency because, with the older standing pilot gas furnace, the pilot remained on even in the summer months. The heat produced by a standing pilot light is negligible. However, it is still added heat to the system in the summer.
The whole purpose of the AC in the summer is to remove the heat from the system. Rather than add heat like a standing pilot would do.

Natural Gas Properties and Furnace Heating Efficiency - Natural Gas is a popular fuel used for heating systems in America and other countries. If we look at the properties of natural gas and the heating efficiency of natural gas furnaces we will see that natural gas furnaces lose efficiency because of what is contained in natural gas as it is delivered to your home for consumption by your natural gas furnace.
Natural gas in its raw form coming straight from the ground needs to be refined to remove impurities that should not be contained in natural gas. As you read below you will see that in the refining process moisture is removed from the natural gas however during the refining process some of the moisture in the natural gas remains and therefore this affects the efficiency of your natural gas furnace.
