Starting from the historical review of the research on determination methods of acid dew point of flue gas in China

this paper reviews the research status

progress and shortcomings of the calculation methods of acid dew point of flue gas in domestic

and summarizes the recent progress in the field of acid dew point at home and abroad. It points out that

the domestic application researches on the following aspects

such as the structural optimization of calculation formula of acid dew point of flue gas

the estimation method for simultaneous decline of acid dew point of the coal combustion flue gas with the flue gas temperature

and the estimation method for wet desulphurization net flue gas acid dew point

have reached the practical level. In engineering application

the basic acid dew point formula of coal quality should be preferred

and the standard value and the upper and lower limit values should be calculated according to coal quality conditions. When the measured flue gas data are available

the basic acid dew point formula of flue gas composition should be preferred. For raw flue gas

denitrification flue gas

cooling flue gas and wet desulfurization net flue gas

different calculation formulas for acid dew point should be selected. At the same time

it suggests that the research on acid dew point of flue gas should weed out the old and bring forth the new. Attention should be paid to the construction of database

the research of testing technology should be strengthened

and the research level of acid dew point calculation method should be further improved.
