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 gasGet Price

Jul 12, 2017 · Originally there are three flue gas lines with the electrostatic precipitator in the recovery boiler of this study as shown in Figure 6. The total flue gas amount, split to three ESPs, is 190 m3n/s. When the temperature is raised to 240 °C, the actual flue gas flow rate is increased by 12 %. One additional flue gas line with a new ESP isGet Price
• If two boilers of similar length and width are compared and one has more flue gas passes (number of times the flue gas travels through the boiler heat exchanger), the boiler with the greater number of passes should have a lower stack temperature. Evaluating Boiler EfficienciesGet Price
Jan 05, 2022 · A boiler flue is a pipe that enables the dangerous gases that are omitted from the boiler to be safely removed and directed away from the property, to be released and dispersed into the atmosphere. The flue is designed to remove water vapour, carbon dioxide and even carbon monoxide gases away from the boiler and property and therefore must also Get Price
A flue gas recirculation system for fire tube boilers includes a duct connected to the boiler gas discharge stack and to a fan. Another duct couples the fan to a specially designed burner in the boiler. Recirculated flue gas is injected downstream of the fuel/air mixture in the burner and cools the flame leading to substantially reduce the NO x content in the boiler stack emissions.Get Price

Condensing Boilers. Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by using waste heat in flue gases to pre-heat cold water entering the boiler. Water vapor produced during combustion is condensed into liquid form, which leaves the system via a drain.Get Price

Feb 01, 2017 · In general, the flue-gas changes in large power plant boilers can affect, for example, the corrosion of the super heater area and other parts of the flue-gas system, the flue-gas cleaning systems and, finally, the emissions of power plants. These effects depend on the characteristics of aerosol generated in the combustion process.Get Price
Oct 15, 2019 · Flue gas starts to condense when the boiler return water temperature drops below the dew point of 55C/130F. The lower the return water temperature, the more condensation, the higher the efficiency. That is why condensing boilers work so well with low temperature, high mass radiant floor heating systems.Get Price
The lowest efficiency boilers are atmospherically vented, Category I boilers. A Category I boiler operates with the flue at negative pressure with respect to the combustion appliance zone or CAZ (i.e., the room where the boiler is located), and the stack temperature is above 140° F, which is hot enough to avoid condensation in the vent.Get Price
