Abstract
A method and apparatus for optimizing the injecting of NO.sub.x inhibiting liquid reagent into the flue gas of a utility or industrial type boiler to reduce emissions of NO.sub.x including a temperature sensor for measuring the boiler flue gas temperature and a moveable conduit for injecting the NO.sub.x inhibiting reagent into the flue gas at a sensed predetermined temperature range.
Claims6
An apparatus for injecting NO.sub.x inhibiting liquid reagent into a boiler having boiler gas flowing therein in response to a sensed temperature range of said gas comprising;
- conduit having a nozzle for injecting NO.sub.x inhibiting reagent into the boiler;
- mounting means for movably mounting the conduit to a wall of the boiler for reciprocating the conduit into and out of the boiler;
- drive means operatively connected to the conduit for moving the conduit along the mounting means;
- a temperature sensor for monitoring boiler gas temperature in the boiler area wherein said conduit will be reciprocated into and out of the boiler;
- and
- control means connected between the drive means and the temperature sensor for operating the drive means in response to a sensed predetermined temperature range.
