A sample probe includes a sample probe tip filter. The sample probe also includes a shield disposed in relation to the sample probe tip filter, the shield being operable to deflect particles in a gas sampling stream away from the sample probe tip filter. The shield has at least one opening that allows the gas within the gas sampling stream and certain ones of the particles in the gas sampling stream both traveling in a substantially flow reversal direction to a primary direction of the gas sampling stream to enter the shield and contact the sample probe tip filter.

Probe for removal of particulates from gas sampling stream

A sample probe includes a sample probe tip filter and a deflector disposed in relation to the sample probe tip filter, where the deflector is operable to deflect particles in a gas stream away from the sample probe tip filter.

Removal of particulates from gas sampling stream

A method of optimizing operation of a fossil fuel fired boiler includes, in an exemplary embodiment, providing a plurality of sensors positioned in different spatial positions within the fossil fuel fired boiler. The method also includes recording sensor outputs, identifying spatial combustion anomalies indicated by sensor outputs, identifying burners responsible for the spatial combustion anomalies, and adjusting air flow of responsible burners to alleviate the spatial combustion anomalies.

Combustion optimization for fossil fuel fired boilers

An apparatus for controlling the emissions of nitrogen oxides from a combustion system includes at least one nozzle assembly having an array of openings for delivering droplets of a fluid chemical agent to a flue gas within the combustion system; a controller operatively coupled to the at least one nozzle assembly for controlling the size and distribution of each droplet; an excitation mechanism operatively coupled to the at least nozzle assembly for providing additional control over the size and distribution of each droplet; and the array of openings arranged for deflecting the droplets to prevent droplet collisions.
