Good afternoon. Thank you very much for accepting our invitation.
My name is Takuya Shinagawa from JFE Engineering Corporation.
Today, I would like to share with you information about our “Energy from Waste” technology, especially about our proven gasification technology, JFE High Temperature Gasifying & Direct Melting Furnace.
Here is what I am going to present today.
First, I begin with introduction of our company, and then, explain about our activity regarding “Energy from Waste” and our gasification technology.
1912, this is the year we started our history as NKK, a steel-making and shipbuilding company.
In 2003, NKK, which was the second largest steel making company in Japan, merged with Kawasaki Steel, the third largest one, and then, JFE group was born.
These are our roots, and this year is our “Centennial year”.
In this 100-year history, we built our first EfW plant in 1968, more than 40 years ago, and now we are constructing our first European gasification plant in Rome, Italy.
JFE Group consists of three companies, steel, shipbuilding and engineering.
Net sales is 32 billion euro, and employees are 54,000.
The largest is Steel, and we, engineering, are the second.
Our net sales is 2.7 billion euro, and employees are 7,500.
Here are our business lines.
We are one of the leading engineering companies, and we supply not only “Energy from Waste” plants, but also pipelines, energy plants, steel structures, industrial machineries, new energy technologies, as well as recycling business.
<CLICK>
This is our newest development “Super RAPIDAS”, a super fast battery charger for EVs, which can charge 50% of battery capacity in only 3 minutes.
We keep developing and launching innovative technologies as a leading technical supplier.
Let’s go to our experience in Energy from Waste field.
I am sorry,,, I know you cannot read this slide well, but, this shows locations of our reference plants.
We have more than 40 years history of EfW as a plant supplier, and have 155 of domestic plants and 7 of overseas plants.
In the last 5 years, our market share in Japan is about 40 %, while the balance is shared by about 10 others.
Because of our trusted position, we have been awarded projects to treat disaster waste after the tsunami in 2011.
For stoker plants, these are 4 examples of our reference plants.
All the plants have been operated over years even in centers of cities.
We have just commissioned this plant in China.
Let’s talk about the reason that we asked you to come here,,,
“JFE Gasification furnace”
While it is relatively new for the European market, Gasification technology is a proven technology that is popular in Japan.
We take advantages of long history as a steel-making company, that inspired the basic idea of our gasifier from an iron blast furnace.
Starting from 1970s with development to our first commercial plant in 2003,
Our technology has proven to be reliable and efficient.
Here is a comparison between an “iron blast furnace” and the “JFE gasification furnace”,
In a blast furnace, iron ore and coke are stacked one after the other,
and heated air is introduced at the bottom to make high temperature and reducing atmosphere to promote iron reducing reactions.
On the right side, our gasifier also has a simple shaft type structure with a cokes bed layer, molten slag basin and three levels of air injection.
These are similar, but, there is one small difference,,,
<CLICK>
That is “size”.
Even our largest gasifying furnace, the height is only 15 m, while the that of the blast furnace is over 100m.
<CLICK>
This is a schematic of our gasifier system.
Waste is stored in the waste banker, and charged into the furnace together with coke and lime.
(Our system does not need pre-treatment, such as drying and shredding..)
The coke works to maintain flow path for gas and slag to enable stable gasification and slag extraction.
It also contributes to keep high temperature to melt the slag and reducing atmosphere.
Limestone works to maintain high fluidity of the molten slag.
Most of waste is gasified and the rest is melted and discharged continuously.
Discharged molten slag and metal are quickly quenched, then recovered after a magnetic separator.
Continuously, the second part of the system is combustion chamber, boiler and flue gas treatment devices, which are in our design, and a turbine for power generation and process.
Fly ash from the secondary combustion chamber and the gas cooling tower, is returned to the furnace to minimize the ash.
Some advantages of our gasifying system.
“Fuel Flexibility”
Not only MSW, but also RDF, sewage sludge, automobile shredder residues, Hazardous waste and Landfill waste., can be treated with this system.
“Minimal emission and residue”
DXNs emission level is very low, and slag contains very small concentrations of heavy metals.
Landfill requirement is low compared to other technologies.
Formation of dioxins are suppressed by three steps.
<CLICK>
First step is the free board.
High temperature and reducing atmosphere conditions is preferable to suppress dioxins formation.
<CLICK>
Second is complete combustion at the secondary combustion chamber.
Temperature and residence time are maintained high and long enough to decompose dioxins.
<CLICK>
Also, activated carbon injection removes dioxins from the flue gas.
By these effects,
<CLICK>
Dioxins concentration is maintained very low level.
Actual monitoring result shows 0.000053 ng-TEQ/m3N, that is 1000 times lower than EU standards.
In terms of heavy metals, they are vaporized to the gaseous phase due to high temperature and strong reducing atmosphere, then concentrated to the fly ash.
As the result of this, slag is safe enough to be used for construction material because of very low concentration of heavy metals,
<CLICK>
on the other hand, you can sell heavy metals in the fly ash as raw materials.
Another advantage over other technologies is highly efficient power generation.
Power generation efficiency is greater than 30%.
Here is an overview of Fukuyama Plant.
Independent verification by a third party confirmed 31% of power generation efficiency.
The fourth advantage is safe and easy operation.
There are 3 points for safe and easy operation.
<CLICK>
Maintaining negative pressure inside the furnace prevents toxic gas leakage.
In case air is accidentally come into the furnace, combustible gases never explode, but only burn because of high temperature condition.
<CLICK>
Second point is no clinker clogging because of fluidized bed condition.
This movement of waste is good for prevention of coagulation of waste particles.
<CLICK>
The last advantage is continuous slag discharging.
Previously, to discharge molten slag, operators had to do dangerous “slag tapping” to make a hole in the refractory, every 1 or 2 hours.
JFE design includes a heat reservoir with an oxygen burner that keeps the slag molten.
“Continuous Slag Discharging” cuts out “slag tapping” and realizes safe operation.
This shows our reference record.
Since 2003, we have built 10 plants in Japan, varies from to 300 t/d.
I would like to introduce our newest gasification plant under construction in Rome, Italy.
This plant is dedicated to power generation from RDF after MBT process.
Let me summarize here.
We have a proven technology.
We have the largest gasification furnace.
We can treat multiple wastes.
We can generate power very efficiently.
We can have low emission level.
We can have profitable slag and metal.
Thank you very much for your attention.
Today, I shared some information about my company and technologies.
We are proud to be in Europe with our technology and experience and confident to offer the best solution for you.
