why boiler exhaust gas need to be maintained

Managing Condensate for Condensing Boilers -

Managing Condensate for Condensing Boilers. process is achieved by passing the piped hot flue gases through the cooler return water flowing back into the boiler. Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of 54°C or less.

Boiler Pipelines Steam Blowing Procedure: Why and

Any impurity being dislodged from the boiler or steam pipes during operation of the power plant can lead to a major damage in the turbine, and so the steam boiler and their associated pipes need to be cleaned before rolling the turbine for the fist time. After that the procedure is done regularly to keep the system clean. Steam blowing procedures are used to clean the boiler system and pipe lines.

Water Handbook - Preboiler & Industrial Boiler

2019-6-6 · Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.

Boiler | Engaged in Thermodynamics

The economizer is the last component of the feedwater system. The economizer extracts heat from the exhaust gas to heat the steam to further improve boiler efficiency. Feedwater enters the boiler though the economizer and rises as steam to the steam drum, where the water and steam are separated.

Boiler Combustion | CleanBoiler.org

Selective non-catalytic reduction involves the injection of a NOx reducing agent, such as ammonia or urea, into the boiler exhaust gases at a temperature of approximately 1400-1600°F. The ammonia or urea breaks down the NOx in the exhaust gases into water and atmospheric nitrogen. Selective non-catalytic reduction reduces NOx up to 70%.
