Hitachi chimney

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

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. 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.

Depending on the additive used for neutralisation we call the process: XeroSorp lime if hydrated lime is usedor XeroSorp bicar if sodium hydrogen carbonate is used. Nitrous Oxides, hitachi chimney.

It is difficult to define ethics precisely. Some people believe that ethics will change as society changes just as morals do. However, I regard ethics as something universal that is rooted in the inherent nature of humanity. I once asked a renowned Buddhist about the essence of ethics. Conversely, without compassion, you do not have true ethics. A recent tendency to view as acceptable any behavior that does not violate laws is not acceptable ethically. Highly ethical leadership characteristics are required especially of managers of global companies, who have significant influence on society and people's lives. We are entering an era when only companies with true ethics, beyond the concept of compliance, will be trusted by international society and survive. Management philosophies prioritizing ethics significantly influenced many business operators and supported the prosperity of Japanese business management. Fusanosuke Kuhara, who operated many businesses during the era of heavy industry development prior to the two world wars, including Hitachi Mine, which became the foundation for Hitachi, Ltd.

Restrictions on wastewater discharge Available space surface, limitations due to existing design of building, etc. Nitrous Oxides. Ultra-tall stacks. Different processes are used to remove these pollutants before the purified flue gas leaves the plant safely through the stack. Our comprehensive range of processes enables us to cover a broad spectrum of requirements. In our patented process, the ammonia is recovered from the effluent and can be re-injected into the post-combustion chamber. The appropriate flue gas treatment approach is chosen in close consultation with the client. Chimneys that were built a long time ago may not meet current standards due to legislative changes. SNCR Process. Each scrubber stage therefore features specific equipment, for example nozzles, liquid distributors, packed beds, ringjets, droplet separators, etc. Flue Gas Treatment. Instead we use two different adsorption additives for neutralisation: hydrated lime and sodium hydrogen carbonate commonly known as sodium bicarbonate. Hitachi Zosen inspects and diagnoses existing steel chimneys based on our high technological capability and abundant experience that have enabled us to provide integrated support for design, manufacturing, and construction.

The ideal temperature range is to be found in the post-combustion chamber, although there it is subject to fluctuation because of variations in load and fuel. 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. In an electrostatic precipitator particles are ionised — in other words electrostatically charged — and then separated out under the influence of an electric field. Depending on the overall flue gas treatment approach, the activated carbon or lignite coke can be introduced and subsequently ejected at different stages of the process:. Organic Carbon Compounds. Corrosive Acid Gases. The scrubber blowdown products are treated in a waste water treatment unit before final discharge. Scenic stacks. The typical design of an ultra-tall stack is a pylon-supported stack in which the steel stack body is supported by a pylon. Instead we use two different adsorption additives for neutralisation: hydrated lime and sodium hydrogen carbonate commonly known as sodium bicarbonate.
