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%.
type have been averaged and, for simplicity, only these averages will be considered in the following discussion. Complete experimental data for each coach are presented at the end of the report in Tables VI, VII, VIII and IX. For each of the 4 constituents, both the concentration in the exhaust gas and the total rate of emission are pre-sented.

Boilers normally have certain amount of optimal excess air and the air input must be adjusted to this level. It signifies a balance between combustion efficiency and amount of air supplied. Excessive “excess air” is identified in the form of either high O2 concentration or low concentration of CO2 in the boiler exhaust gas.
Improving Boiler System Efficiency: O2 Trim As the temperatures and air density in boiler rooms change, the combustion will vary slightly. O 2 Trim senses these changes by measuring the oxygen in the exhaust of the boiler and sending a message back to the servo control system, which will then correct for the changes.
