Hitachi chimney

Incinerating waste produces exhaust gases laden with diverse hitachi chimney. Different processes are used to remove these pollutants before the purified flue gas leaves the plant safely through the stack. For decades HZI has been doing research into flue gas treatment and developing new and effective treatment systems, hitachi chimney.

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.

Each flue gas treatment module serves a specific purpose. Organic Carbon Compounds. If the catalytic surface is sufficiently large, part of the dioxins and furans are destroyed at the same time. 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. Infrastructure and Disaster Prevention Systems. In an electrostatic precipitator particles are ionised — in other words electrostatically charged — and then separated out under the influence of an electric field. Energy Recovery Waste to Energy. Wet scrubbing is the most effective method for removing acid gases from even heavily burdened flue gases. The scrubber blowdown products are treated in a waste water treatment unit before final discharge. Incinerating waste produces exhaust gases laden with diverse pollutants. Therefore, we do not carry out performance evaluation work. In addition to inspecting and repairing the inside of chimneys during suspended operation, Hitachi Zosen also considers reinforcement for chimneys during operation.

The individual scrubber stages have their own water circuits. Instead we use two different adsorption additives for neutralisation: hydrated lime and sodium hydrogen carbonate commonly known as sodium bicarbonate. If the temperature is too low, the reaction slows and a large portion of the ammonia reaches the stack unused. Organic Carbon Compounds. Recently when stacks are to be installed in the suburb of a town, it is indispensable to build a stack that fits in with the surrounding scenery. The numerous processes that have emerged can be used individually or together to create high-performance integrated systems. Hydrated lime is injected into the fluidised bed reactor to neutralise corrosive acid gases. The SCR process is flexible in terms of operating temperature, and can be deployed at various points along the flue gas treatment process chain. Corrosive Acid Gases. 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. Achieving higher NOx removal efficiency requires injecting more ammonia than is consumed. The Main Advantages of Adsorption onto Activated Carbon or Lignite Coke: Can easily be integrated into the various processes for removing acid gases XeroSorp, SemiDry, wet scrubber Very simple system with only a small number of components storage and conveying Proven technology with a long and successful track record in industry. 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.
