Maerz news

Dear Readers and Friends

Interesting picture – isn’t it? Why did we choose it for our front page?

The answer is simple: since May 1999 we have been publishing our Maerz News on paper and distributing it

to our customers and friends worldwide. This not only entailed a lot of logistics on our part but from today’s

perspective, in the day and age of the Cloud and the Internet, we would prefer to use resources otherwise.

We have therefore decided to make a change and in future will post our news on the Internet only.

At Maerz we are busy not only with new orders, but also with our continuous efforts to improve our product

portfolio for further optimisation of our design giving you more flexibility with future extension plans (such

as adding other fuels to your existing systems) as well as facilitating the maintenance of our kilns. We will

introduce these new features wherever appropriate in our new proposals for lime kilns.

We are also working hard on expanding our competence for turn-key installations in various areas of the

world together with our partner companies within the ThyssenKrupp group. This requires a lot of knowledge

of the specific conditions in each country, which we can provide to you due to ThyssenKrupp’s regional set

up. We will emphasise this subject in our presentation at the International Lime Association's conference in

Vancouver in October this year.

Please enjoy reading this last printed edition of our Maerz News, featuring information about selected new

orders as well as completed projects.

SMA Mineral Oy, Finland

SMA Mineral Oy from Tornio, Fin-

land, has been operating a Maerz

PFR Kiln for more than ten years in

its Röyttä plant. The kiln ordered in

2001 is of the Finelime® type, pro-

ducing between 425 and 525 tons of

quicklime per day, burning limestone

with grain sizes of 15 to 40 mm or

40 to 60 mm and using both recycled

and heavy oil as fuels.

The client has now signed an order

with Maerz for the conversion of the

existing lime kiln to gas firing, using

CO gas with a calorific value of ap-

prox. 11’150 kJ (2’665 kcal) per m3n

equipment and technical assistance

for the installation of a Maerz PFR

kiln plant at its Kemaman

(Terengganu) plant. The lime will be

supplied to Eastern Steel Sdn. Bhd.

located adjacent to the lime plant, a

1.5 MT integrated steel complex

currently under construction.

The kiln of the R4S type will pro-

duce 500 tons per day of quicklime.

A mixture of converter and blast

furnace gas with a calorific value of

approx. 4’200 kJ (1’000 kcal)/m3n

will be used as fuel and limestone

with a grading between 40 and 80

mm will be processed in the kiln.

Maerz will supply materials and

equipment, such as special steel

structures for the suspended cylin-

ders and other key equipment.

The kiln plant is scheduled for start-

up during the first half of 2015.

Implemented Project in Indonesia

PT Krakatau POSCO Chemtech Calcination

In early 2012 POSCO E&C, as the

buyer, and Maerz Ofenbau AG, as

the seller, signed a contract for the

installation of 3 x 330/350 tpd Maerz

PFR Lime Kilns, to be erected in

Cilegon for PT Krakatau POSCO

steel plant, a joint venture of Kraka-

tau Steel and POSCO.

The kilns of the Finelime type F2S

will each produce 330 to 350 tons of

burnt lime per day, processing lime-

stone with grain sizes between 20

and 80 mm and using coke oven gas

as fuel.

Shortly before the end of 2013 the

erection work of the kilns was com-

pleted and all systems were inspect-

ed and tested by POSCO E&C and

PT.KPCC, thus enabling the start-up

of the kilns as well as the execution

of the contractual guarantee test runs.

Consequently, the kilns were taken

over by PT.KPCC.

At the beginning of 2013 CELCO

S.A., domiciled in Constanţa, Roma-

nia, entrusted Maerz with the supply

of engineering services, license,

know-how, materials and equipment

as well as supervision services for

the construction of a new Maerz lime

kiln in their Corbu (Constanţa Coun-

ty) lime plant.

One year later, in January 2014, the

kiln entered the industrial production

stage and the contractual perfor-

mance test run was carried out. The

quality and performance figures

reached are shown in the adjacent

table.

The Maerz HPS (High Performance

Single Shaft) Kiln built within the

scope of this contract is of the kiln

type H3-1 and produces 150 tons of

quicklime per day. Natural gas is

used as fuel and limestone with a

grain size of 20 to 40 and 40 to 80

mm are processed in this kiln.

As announced in our December 2011

“Maerz News”, Hyundai Rotem

Company from Seoul, Korea, en-

trusted Maerz with the supply of

equipment, technical documentation,

technical assistance and training ser-

vices for another two PFR Kilns –

this time Finelime® Kilns - to be

installed in the Dangjin Works of

Hyundai Steel Corporation. The F3P

type kilns were to each produce up to

500 tons of burnt lime per day, using

coke oven gas as fuel.

The new kiln plant was recently

commissioned and the industrial

production started. During the con-

tractual guarantee test run with a

limestone grading of 15 to 40 mm

and 40 to 80 mm resp. the perfor-

mance and quality parameters as

listed in the adjacent table were

achieved.
