Flue Condensation Problems Why | Gas Heating Safety 101

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.

Condensing technology recovers the condensation heat retained latently in flue gases, that is a part of energy that normally disappears up the chimney in other heating systems. Thanks to lower fuel consumption and lower heating costs, condensing boilers usually pay for themselves in few years, reducing costs up to 20% in comparison with

PDF 1.4 Natural Gas Combustion - US EPA

Improperly tuned boilers and boilers operating at off-design levels decrease combustion efficiency resulting in increased CO emissions. In some cases, the addition of NOx control systems such as low NOx burners and flue gas recirculation (FGR) may also reduce combustion efficiency, resulting in higher CO emissions relative to uncontrolled boilers.

Is a high efficiency, condensing gas boiler the best

Condensing boilers produce heat by burning natural gas or propane fuel. The word "condensing" refers to the fact that these appliances are able to extract heat from the combustion process so efficiently that the flue gases leaving the boiler are at a much lower temperature than in a conventional boiler. The temperature of these flue gases

Boiler Design: Composition, Benefits, & How to Start

A Steam boiler is a steel pressure container in which water under pressure is transformed into steam by the use of combustion. In other words, the boiler is just a heat exchanger which uses radiant heat and hot flue fumes, released from burning fuel, to produce vapor and hot water for heating and processing loads.

According to the latest gas boiler flue regulations, the pipe should be continuous and have all the joints assembled safely and correctly. Keep in mind that gases expelled from traditional units differ from those expelled from high efficiency ones. So, the flue type differs as well. Most modern models feature two pipes. One is fitted inside the
