The flue is also a safeguard against fire. If the waste gases come into contact with other combustibles, a fire can easily break out. Below are three types of venting for gas furnaces. 1. Natural Vent. It operates on natural air convection and is also known as the Type B vent. Type B vents are a standard design that most modern gas furnaces use.
Since the heated flue gas is less dense than the ambient air surrounding the boiler, the flue gas rises in the chimney, pulling denser, fresh air into the combustion chamber. Most modern boilers depend on mechanical draught rather than natural draught.
4 Depending on how the venting systems is sized (positive or negative pressure at boiler flue outlet) may result in a change in Category classification. 5 Type B Vents are for negative flue pressures and for flue gas temperatures not exceeding 400°F.
This lost BTU is now captured and saved to various heat sinks such as boiler feedwater, cold makeup water, process water, swimming pool water, glycol, and thermal fluids.

2 The steady state efficiency is determined from the relationship between net flue gas temperature (rise above ambient) and the flue gas composition (%CO 2). 3 A condensing boiler is one in which, under continuous operation, water may collect within the boiler or in the venting system . Bryan Boilers with steady state efficiencies over 83 %
This picture shows furnace flue condensation problems. This problem is caused by hot gases cooling too quickly in the flue. As the hot gasses cool, the moisture in the gases condenses and start dripping back down the flue. Typically, there is a combustion issue or bad flue design. This problem can be solved by making sure the gases are hot ...
