How Efficient is a Condensing Boiler? (2021) |

The dew point temperature is the most reliable unit of measure for the humidity and air comfort. Under normal conditions, the dew point for natural gas is around 57 degrees Celsius. Hence, in order for the boiler to work in condensing mode, the coolant temperature in the reverse loop should not exceed 57 degrees Celsius.

How Is The Low Temperature Corrosion of Boiler Caused

2020-8-25 · The dew point of flue gas is obviously increased by the presence of sulfuric acid vapor. For example, the pressure of water vapor in the flue gas of an oil fired boiler is about 0.008~0.014Mpa, and the corresponding thermodynamic dew point is 41~52℃.

Sootblower and Boiler Cleaning Terminology,

The cleaning medium is almost always steam, but air is an alternative. The steam velocity is low in comparison to boiler sootblower applications to avoid mechanical or erosive damage to the catalyst substrate, yet high enough to dislodge loose particulate in the catalyst channels and re-entrain them in the flue gas flow.

How to improve boiler efficiency by evaluation

2019-12-24 · steam fuel ratio (SFR) in Boiler: from this equation steam fuel ration is =1500/110=13.63 Kg/kg. In practice in the field the key performance indicator is the SFR (Steam fuel ratio). If steam fuel ration is high then it is considered that the boiler is more efficient. An idle boiler performs at 84 to 86 % of the efficiency, So the steam fuel

The steam treatment process is the controlled oxidation of metals to produce a thin layer of oxide on the surface of a component. This process can be used to provide a component with increased corrosion resistance, better wear resistance, increased surface hardness, an attractive surface finish, and, in the case of porous materials such as powder metal, seal the part porosity and increase the

2021-1-26 · 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 to 300 to 350/sup 0/F.
