Q: What is Flue Gas Recirculation (FGR) in gas boilers?
A: Flue Gas Recirculation (FGR) is a technique used in gas boilers to reduce NOx (nitrogen oxides) emissions. It involves recirculating a portion of the boiler's exhaust gases back into the combustion chamber. This process lowers the oxygen concentration in the combustion air, reducing the flame temperature and thereby decreasing NOx formation.
Q: How does FGR contribute to environmental protection?
A: By reducing NOx emissions, FGR play...
Gas-fired boilers use gaseous flammable gases (including liquefied combustible gases) as fuel. These gaseous fuels have relatively higher calorific value and less pollutant emissions, and are gradually becoming popular among corporate users.
100-ton gas-fired hot water boiler refers to the gas-fired hot water boiler with rated heat supply of 70MW. 100-ton gas-fired hot water boiler is often used for central heating in cities or park heating.
The furnace body structure of ZOZEN SZS series 100-ton gas-fired hot water boiler adopts large-volume furnace design, and with the imported ultra-low nitrogen burner, it can effectively inhibit the generation of NOX, which is better than the emission standard of 30mg/Nm³. With wast...
The boiler chimney is one of the essential facilities in the process of building a gas boiler room. Its main function is to provide ventilation for the hot flue gas or smoke emitted by the boiler. Usually, when making the chimney of gas boiler, choose the vertical structure as much as possible to ensure the gas flow smoothly, and the sucked air enters the so-called chimney combustion or stack effect.
Different users have different requirements for boiler configuration. For example, some users need NOx emission less than 30mg/Nm3, and some users only need it less than 80mg/Nm3. The better auxiliary equipment configuration is used, the price of boiler will naturally rise.
Different users have different requirements for the configuration of the whole boiler system, and the brand and quantity of auxiliary machines also affect the price. The better the brand, the more expensive the price. For ex...
Fuel injection nozzle of combustion oil pump of gas boiler does not inject fuel. Possible causes include blockage and leakage of oil supply pipeline. The solution is to clean, repair or replace;
The gas-fired boiler is operated by an advanced combustion machine, equipped with automatic gas supply and ignition combustion system, and the gaseous fuel is easy to burn. Therefore, the gas-fired boilers need not be equipped with blower and induced draft fan components.
The burner of natural gas boiler refers to the burner for gas-fired boiler. Gas burners are divided into natural gas burners, urban gas burners, LPG burners and methane burners. The burner of natural gas boiler is just one kind of burner.
