Wet Electrostatic Precipitators for Utility Applications
May 03, 2011 The flue gases are drawn away from the recovery boiler at the exit of the electrostatic precipitator; this maintains an air pressure below ambient so that gases will be sucked into the boiler in the vicinity of the black liquor nozzles to improve the safety of the operation. Some example reactions in each zone are:
An electrostatic precipitator is a highly efficient particulate collection device that removes particulate matter from a gas stream using electrostatics. Also known as an electrostatic air cleaner, this device uses electrical charges to remove either solid or liquid droplets (or impurities) that come from gases in smokestacks
recovery boilers and 0.015 gr/dscf for new recovery boil-ers [1]. Since electrostatic precipitators (ESPs) are the most commonly used devices for removing particulate matter from recovery boiler stacks, it is essential for kraft pulp mills to operate their ESPs at the highest efficiency pos-sible to maintain the maximum production rate and meet

static precipitator where the remainder of the entrained solids are precipitated into the liquor flow system under the precipitator. Roberts1 has described this system in detail. The second system is shown schemati-cally in Fig. 3. Here the gases from the recovery boiler are passed into a high energy evaporator-scrubber where both

the electrostatic precipitators could now be properly designed. Figure 5 is a resume of the precipitator design data. Physical installation began in June 1957 and was completed in May 1959. Precipitator Physical Layout and Operation The electrostatic precipitators for the No. 5 Open Hearth Shop are located in the area south of the furnace and
Sep 09, 2017 Electrostatic Precipitator: Teknologi Mengendalikan Polusi Abu (Fly Ash) Dari Boiler Published by Onny Apriyahanda on January 18, 2013 January 18, 2013 Abu adalah material padat yang tersisa setelah terjadinya proses pembakaran
Gas flow rate is a fundamental factor in the design and performance of electrostatic precipitator. The quantity of combustion gas produced in the boiler depends on the composition and amount of coal burned, the excess air used for combustion and the air in-leakage through the furnace, flues and air-preheaters. The volume flow rate through
Features of Wet Electrostatic Precipitator Suitable for applications requiring a much higher degree of gas purity at outlet than can be readily achieved by dry type ESP. Using water in removing the collected dust, the wet type ESP can achieve high dust removal efficiency (down to 1 mg/m 3 N) without being affected by the high or low electrical
Electrostatic Precipitator. The major application of ESPs in cement is at the Clinker Cooler which is an essential part of a cement process. Functionally, it cools down the red hot clinker discharged from the kiln. Various designs of clinker cooler are used in the industry, of which, the grate coolers are the most common
An electrostatic precipitator is a type of filter (dry scrubber) that uses static electricity to remove soot and ash from exhaust fumes before they exit the smokestacks. This one common air pollution control device. … Smoke consists of tiny particles of soot that
Sep 11, 2013 Figure 2. Percentage capture of dust particles in the ESP. How it Works Electrostatic Precipitator The workings of the electro static precipitator (ESP) are (1) passing the exhaust gas (flue gas) through an electric field formed between the discharge electrode to the collector plate, flue gas containing dust grains initially neutral and charged at the time of
Performance of the electrostatic precipitator in a kraft pulp recovery plant strongly relies on characteristics of the particles carried by the combustion gas of the recovery boiler

A recovery boiler accomplishes three major tasks; burning the black liquor, recovering the inorganic chemicals for ... This is collected in an electrostatic precipitator and returned to the black liquor being fired. In addition, some inorganic collects on
Recovery Boiler No. 1 at Canfor Pulp & Paper’s ill located in Prince George, British m Columbia, Canada. It consists of one casing with the following configuration: two isolatable chambers, five 12 ft long mechanical fields, 39 ft tall collecting plates, 12 inch wide gas passages, and 28 gas passages per chamber. The ESP was compliance tested n i
The invention relates to a process for purifying recovery boiler electrostatic precipitator ash (via 19) from chlorides (Cl) and potassium (K), and recover useful pulping chemicals such sodium sulphate (Na 2 SO 4 ). The inventive process uses two centrifugal separation stages (2a, 2b) in series with a leaching stage (1 a and 1 b) ahead of each centrifugal stage
Electrostatic Precipitators (ESP) for woody biomass heaters by OekoSolve. OekoSolve develops electrostatic precipitators (ESP) for woody biomass heaters up to 3 MW and the wood chip dryer with an integrated electrostatic precipitator up to 10 MW. The particulate filters, which are based on the electrostatic principle, ensure the compliance with the statutory
Aug 27, 2018 The electrostatic precipitator recovers the fly ash and the pulp boiling chemicals that leave the boiler with the flue gases and they are then recycled back to the pulp process. The more efficient the recovery boiler’s electrostatic precipitator is, the more closed the resulting process is. Both the environment and the forest company benefit
For recovery boilers, precipitators are used to collect the residual salt cake in the flue gas. A recovery boiler is a unique application for a precipitator due to the small particulate size and the tendency for the cohesive ash particles to stick together. The resistivity of the particulate is low, so it is collected easily in the ESP
Jul 12, 2017 Originally there are three flue gas lines with the electrostatic precipitator in the recovery boiler of this study as shown in Figure 6. The total flue gas amount, split to three ESPs, is 190 m3n/s. When the temperature is raised to 240 C, the actual flue gas flow rate is increased by 12 %. One additional flue gas line with a new ESP is
