Portable UV Flue Gas Analyzer Gasboard 3800UV|Hubei Cubic

In boiler operation, heat loss to flue gases amounts to as much as 20 to 25% of the heat input. To recover heat from flue gases, economizers are generally used to preheat boiler make-up water or forced draft combustion air. The dew point usually limits the practical lower temperature of the flue gas …

Fuels Flue Gases and Average Dew Points

A fraction of the sulfur dioxide, sometimes as high as 10%, is oxidized to sulfur trioxide. Sulfur trioxide combines with water to form sulfuric acid at temperatures at or below the dew point of the flue gas. In a boiler, most of the sulfur trioxide reaching the cold end is …

Flue gas temperature: Flue gas temperature to chimney must be as low as possible. Lower temperature in flue gas indicated higher energy conversion in boiler. acid dew point must be considered while lowering temperature. Flue gas heat may be utilized in preheating boiler feed water or combustion air.

Coal fired boiler - Guideline for energy efficient

• Flue gas recirculation (FGR) – Flue gas from the outlet of the boiler is mixed with the combustion air to the burners. – FGR reduces the combustion temperature and lowers the localized O2 concentration in the primary combustion zone to achieve a reduction in NOx. – Increasing the flue gas flow through the convective pass of the boiler

coal fired boiler flue gas temperature dew point

But in recent years, some investigations conducted on coal-fired boilers suggested that the flue gas temperature could be lowered beyond the sulfuric acid dew point. Flue gas generated by coal combustion contains a considerable amount of fly ash, and the alkaline components in the ash, such as CaO, reacted with SO 3 and H 2 SO 4 from flue gas
