NO removal efficiency increases quickly with enhancement of molar ratio of gas to NO at 1 050 ℃ and 1 150 ℃,but it increases in the beginning and then decreases at 1 200 ℃ when the reburn fuel is natural gas.

Results of the experiments show that the NO removal efficiency increases quickly with enhancement of molar ratio of natural gas to NO and the reburn temperature; there exists an optimum reburn stoichiometric ration (0.

By the deeply analysis of main factors influencing on the denitration efficiency and ,particularly,of the parameters of the catalyst,the design optimization and operation optimization for denitration system catalyst reactor,maintenance overhaul and soot blowing control were researched,and their influence on catalyst service life were discussed too.

With the increasing of the mixing time,above 950 ℃,the denitration efficiency of SNCR process decreases,and the temperature window of SNCR becomes narrow.

Under prerequisite condition of ensuring the escape rate of ammonia,the denitrification efficiency can reach the designed value.

By using a self-prepared "oxygen-enriched type" highly active absorbent,the influence of CO2 and O2 in flue gas on the desulfurization and denitrification efficiency of the highly active absorbent and the influence of the coexistence of SO2 and NOx on the desulfurization efficiency were experimentally studied at an optimum technological condition and through the use of a fixed bed.

8% denitrification efficiency can be reached when the urea concentration is 5%,gas velocity 0.

As the key component of WX/4U desulfurization equipments,the desulfurization performance of venture scrubber has an important effect on the removal efficiency and operational cost of the whole desulfurization equipments.

The effect of different operational parameters on the removal efficiency of WX/U-desulfurization equipment is investigated experimentally.

To enhance SO2 absorption rate and removal efficiency,hydrogen peroxide as a strong oxidant was added during the spray water humidification in the process of semi-dry flue gas desulfurization.

A series of tests have been performed of such main factors affecting the desulfuration efficiency as sealing liquid height,pH value of sprinkling liquid,flue-gas wetness and inner tower perforation air velocity.

An experimental study was performed of the mechanism governing the impact of important operating parameters on the desulfuration efficiency of a spray tower.

Combustion characteristics,temperature distribution, NO_x,SO_2 emission characteristics and desulfuration efficiency under diffferent atmospheres were compared.
