Boiler Flue Regulations 2021: A Simple Guide | Skills

When a boiler is functioning, it produces waste gases that need to be eliminated from the system. The flue is essentially the pipe that transports these gases out of the boiler. As the gases can be potentially harmful, its important that the flue is situated in such a way that the waste gases do not re

Flue gas treatment | technology | Britannica

Flue gas treatment, a process designed to reduce the amount of pollutants emitted from the burning of fossil fuels at an industrial facility, a power plant, or another source. Flue gasthe emitted material produced when fossil fuels such as coal, oil, natural gas, or wood are burned for heat or powermay contain pollutants such as particulates, sulfur dioxide, mercury, and carbon dioxide.

Flue Gas Condensation Could Be Killing Your Boiler | Boiler

Flue gas condensation is a good thing when going for record efficiencies in a hydronic system, but the boiler and stack must be designed to handle the condensate. If either are incorrectly selected for the application or are not installed properly, flue gas condensation will be the silent killer.

Boiler - Wikipedia

Early boilers provided this stream of air, or draught, through the natural action of convection in a chimney connected to the exhaust of the combustion chamber. 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.

1.4 Natural Gas Combustion - US EPA

from natural gas-fired boilers are flue gas recirculation (FGR) and low NOx burners. In an FGR system, a portion of the flue gas is recycled from the stack to the burner windbox. Upon entering the windbox, the recirculated gas is mixed with combustion air prior to being fed to the burner. The recycled flue gas

Flue Gas Recirculation (FGR) - CCA Combustion Systems

Flue Gas Recirculation (FGR) is a powerful nitrogen oxide (NOx) control technique that significantly reduces NOx emissions by recirculating flue gases from the boiler exhaust duct into the main combustion chamber. This process reduces peak flame temperature and lowers the percentage of oxygen in the combustion air/flue gas mixture, thereby

Nov 05, 2019 · Definition: A boiler flue is a component which enables gas to escape safely from boiler. In most cases, this is a pipe or a duct, which is fitted to the boiler to carry exhaust gases away from your home safely. The aim is to remove waste products without exposing you or anyone around you to them.
