In order to verify the feasibility of blending a large proportion of ammonia in a coal-fired unit
a numerical simulation model was established using a 660 MW wall type tangentially-fired boiler as an example. The impact of ammonia blending ratio
ammonia injection location
and primary and secondary air distribution methods on combustion in the furnace was analyzed. Results show that blending ammonia in coal-fired boiler leads to a decrease in flue gas temperature and an increase in NO
x
mass concentration in the furnace. The greater the ammonia blending ratio
the more significant the decrease in flue gas temperature and the increase in NO
x
mass concentration. When the ammonia blending ratio increases to 40%
the average flue gas temperature in the furnace drops by approximately 50 K
and the outlet NO
x
mass concentration increases by 29.4%. Measures such as blending ammonia in higher-level burners and increasing the primary air ratio can reduce the NO
x
mass concentration at the furnace outlet while ensuring complete combustion of ammonia and coal.
