NTPC owns several pulverized coal fired power plants of the MWe class equipped with conventional Electrostatic Precipitator (ESP). The exemplary design value for the dust concentration in the clean gas is 42 mg/Nm³ at full load whereas the measured present value is mg/Nm³ with % ash content in the coal.

    The report gives results of the full-scale demonstration of Limestone Injection Multistage Burner (LIMB) technology on the coal-fired, MW, Unit 4 boiler at Ohio Edison's Edgewater Station. eveloped as a technology aimed at moderate levels of sulfur dioxide (SO2) and nitrogen oxides (NOx) emissions control for relatively low-cost retrofit applications on older plants, LIMB . The collection electrodes in each of the six fields are m (6 feet) in depth and m (30 feet) high. The discharge electrodes have a diameter of mm ( inches) and the average spacing between each wire per field is cm (9 inches) [8 wires per gas passage per m (6 ft) field].

Low NOX burners with separated overfire air were installed on Unit 7 during a outage. For purposes of this test program, the load was fixed at MWe. Yates Unit 7 is subject to a particulate emission limit of lb/10 6 Btu. The unit also has a 6-minute average opacity limit of 40 percent, and a 4-hour average opacity limit of 34 percent.
