Hitachi chimney

Incinerating waste produces exhaust gases laden with diverse pollutants. Different hitachi chimney are used to remove these pollutants before the purified flue gas leaves the plant safely through the stack.

Based on the design, manufacturing, and building technologies we acquired through our experience in building ships, bridges, water gates, and ocean structures, since we have recorded building more than steel stacks in Japan and overseas and contributed to creating social infrastructure. In addition to new installations of ultra-tall stacks reaching around meters and stacks incorporating an earthquake-proof system, we can respond to customers requirements with our total engineering capabilities from design to onsite construction including repairs, reinforcing works, and diagnosis of earthquake-proof performance of existing facilities that are growing in number these days. The typical design of an ultra-tall stack is a pylon-supported stack in which the steel stack body is supported by a pylon. The pylons also serve as scaffolding for maintenance purposes, thus reducing ongoing operating costs. In the building method, which we developed before other companies, we use the jack-up method, which enables the welding of stack bodies on the ground.

Other Metals Removed with flying dust in a fabric filter or electrostatic precipitator. We propose, in addition to conventional stacks, a new stack design that has both economical efficiency and esthetic features such as our super-membrane stacks. Incinerating waste produces exhaust gases laden with diverse pollutants. Adsorption onto Activated Carbon or Lignite Coke. Wet scrubbers consist of several stages, each of which fulfils a particular purpose: separating out specific pollutants, saturating flue gases, or extracting heat. Contact Us. We also propose repair methods according to the deterioration situation, provide repair work, and respond with total engineering from design to on-site construction. The Main Advantages of the XeroSorp Process: Low operating and maintenance costs thanks to simple design and operation Low process investment and minimal infrastructure costs thanks to compact design Minimal use of adsorption additives and very low residue generation XeroSorp bicar reaches even the low BREF emission values under optimal conditions. Flue Gas Treatment. In an electrostatic precipitator particles are ionised — in other words electrostatically charged — and then separated out under the influence of an electric field. Organic Carbon Compounds. Instead we use two different adsorption additives for neutralisation: hydrated lime and sodium hydrogen carbonate commonly known as sodium bicarbonate. The pylons also serve as scaffolding for maintenance purposes, thus reducing ongoing operating costs.

It is difficult to define ethics precisely. Some people believe that ethics will change as society changes just as morals do.

In the SNCR selective non-catalytic reduction process, nitrous oxides NOx react with ammonia and are chemically converted into nitrogen a natural constituent of air and water vapour. The Main Advantages of the HZI Wet Scrubber: Pollutants are separated systematically in several stages Achieves very high separation rates for acid gases low emissions Constant separation even when there are changes or fluctuations in load Low volumes of residue thanks to stoichiometric consumption of chemicals Significantly boosts plant efficiency if condensing stage or condensing scrubber is fitted Low-maintenance process with high availability Any desired combination of different stages is possible to adapt to process and client requirements Highest separation rates for acidic pollutant gases guaranteed compliance with the lowest BREF emission values. Corrosive Acid Gases. The HZI SemiDry system involves a semi-dry sorption process employing the principle of the circulating fluidised bed. Wet scrubbing is the most effective method for removing acid gases from even heavily burdened flue gases. An overarching water distribution system ensures that all stages are supplied with sufficient water and that the separated pollutants are separated via the scrubber blowdown. When putting together the right overall approach we take account of the following factors: What is the key performance indicator for flue gas treatment? Using a catalytic converter allows the reduction of nitrous oxides at significantly lower temperatures, and is considerably faster than the SNCR process. The Main Advantages of the Electrostatic Filter: High separation efficiency for solids and dust Constant separation even when there are changes or fluctuations in load Low operating and maintenance costs Long lifetime and high availability. Type of waste, including any pretreatment Type of combustion process, plus waste throughput and thermal capacity What emission limits are to be complied with?
