摘要： In a system for monitoring the operating condition of a pulverizer, a sensor interface module positioned on or proximal to the pulverizer. The sensor interface module is operable to receive information generated by one or more sensors mounted on the pulverizer. An operator control station is in communication with the sensor interface module and is operable to receive data from the sensor interface module relevant to the signals received from the sensors. The operator control station is also operable to generate operational information indicative of a functional characteristic of the pulverizer and to track the operational information to determine whether degradation of the functional characteristic is occurring.

摘要： An integrated system [1000] is described for reducing operating costs of power plants while keeping gaseous pollutants in exhaust flue gasses, such as Mercury (Hg), below acceptable limits. Controller [1800] monitors and controls operation of a scrubber [1300], activator injection system [1400], sorbent injection system [1500] and a filter [1600]. Scrubber [1300] provides a neutralizer to remove SO2 emissions. Activator injection system [1400] provides and activator that increases affinity of the pollutant gasses for a sorbent. Sorbent injection system [1500] employs novel low friction injection lances [1590] that evenly distribute the sorbent particles. A filter [1600] collects the sorbent particles that cake onto filter bags [1620] that are periodically cleaned. A controller [1800] receives the costs of materials consumed and the filter bag life for the plant and performs an optimization of the multiple variables to minimize costs while keeping the pollutant emissions below a prescribed limit.

摘要： Techniques for monitoring operation of a flame ignitor are provided. In one embodiment, multiple inputs are received. The inputs are received from at least one of a first group of inputs and a second group of inputs. The first group includes a flame rod voltage, a stop signal for deactivation of the flame ignitor, a fuel supply interruption signal, and an air supply interruption signal. The second group includes a start signal for activation of the flame ignitor, and a flame proven signal indicating presence of a flame produced by the flame ignitor. If inputs from the first group are received, a cause of a failure of the flame ignitor is determined. If inputs from the second group are received, a reliability of the flame ignitor is determined.

摘要： A method of operating a solid fuel-fired furnace having a plurality of windboxes each having a plurality of compartments through which fuel and air are introduced into the furnace and a fuel and air arrangement operated in accordance with the method are provided. Solid fuel is fed into the furnace and primary air and fuel are fed through the same compartments into the furnace in a direction tangential to a first imaginary circle generally located in the center of the furnace so as to interact with the fuel fed into the furnace so as to create a rotating fireball. Overfire air and offset air are also supplied into the furnace, the offset air being that portion of the air supplied to the furnace so as to support a second imaginary circle concentric to, and having a larger diameter than, the first imaginary circle. The total air supplied into the furnace is thus composed of primary air, additional combustion supporting air, overfire air, and offset air supplied in accordance with a prescribed relationship between the components of the supplied air.
