Boiler Stainless Steel Exhaust Flue Stack: This is a photo of a boiler stainless steel exhaust stack. It is used for venting corrosive boiler combustion gases. As the flue gases leave the boiler they cool and depending on the dew point of the gas, the gas will experience a change of state. It will change from a gas to a liquid. This liquid is highly corrosive and only special flues like stainless steel vent can be used when this occurs. Stainless steel prevents premature failure of the boiler vent.
There are many considerations to consider with a new installation of a heating system in comparison to the type of vent to be utilized. The venting system used to vent the gases from the boiler or furnace safely outdoors. It is imperative that safety guidelines be followed when installing any type of venting system for furnaces or boilers using fossil fuels. For detailed information concerning code requirements for installation of venting systems see the IFGC or International Fuel Gas Code. Chapter 5 and Appendix C of the IFGC offer detailed requirements for the installation of venting systems.
Never sacrifice safely, consult a professional when in doubt. There are many rules to follow. A professional will know these rules and apply them as they install the system. They will also, have the system inspected by the code official in your area to double-check to ensure safety guidelines were followed

Bacharach Combustion Analyzer
Bacharach Combustion Analyzer Furnace Testing - The combustion analyzer is used to test gas and oil furnaces to make sure the combustion process is as efficient as possible. This multi-function HVAC test instrument can also be used to test spaces for carbon monoxide, test building pressure, all in addition to testing the combustion process of the furnace.
The combustion analyzer allows an HVAC technician to test the flue temperature, the amount of oxygen in the furnace flue gases, the amount of carbon monoxide in the flue gases, the amount of carbon dioxide in the flue gases, and the pressure of the flue. All these readings are necessary so the HVAC technician can make adjustments to the burner settings to ensure efficient combustion using the combustion analyzer. (more…)

HVAC Near Boiler Piping Components - HVAC near boiler piping is very important to a good hot boiler loop circulation of the water. Hot water loop piping is key to maintaining good water flow throughout the system. The placement of valves, the circulator pump, and other loop controls are generally installed near the boiler.

Natural Gas Regulators
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.
