Recent Maerz Ofenbau projects in Asia

Liuzhou I&S Co., Ltd., PR China

Impressive plant, impressive commissioning and impressive kiln performance of 3600 t burnt lime per day at highest efficiency – this is the largest realised Maerz lime kiln plant in the world.

Sinosteel Co., Ltd. China, entrusted Maerz with the supply of six PFR lime kilns for Liuzhou I&S Co., Ltd. as the end-user. Together with the new plant in South West China, Liuzhou Iron & Steel now operates eleven 600 t/d Maerz PFR kilns.

The six new 600 t/d kilns of the circular type R4S process limestone with a grading from 40 to 80 mm and use pulverised hard coal as fuel for firing, which is milled directly at the calcination plant. Within the scope of the contract, Maerz in cooperation with thyssenkrupp Industrial Solutions (China) Co., Ltd., Shanghai, supplied engineering, license, know-how as well as technical assistance services for commissioning of the new lime plant together with on-site training of the end-user’s operating personnel.

The first kiln was ready to be ignited at the end of January 2019. The remarkable journey culminated in the ignition of kiln no. 1 on 26 January 2019 at 15:58, according to Chinese tradition both a lucky date and a lucky time – a good omen for the continuing successful course of the project. While the locals were celebrating the Chinese New Year, nightly fireworks and an energetic atmosphere accompanied the gentle heating up procedure of kiln no. 1.

The remaining five kilns became operative in June 2019. Three kilns were erected and commissioned, at times simultaneously, which was a huge challenge and required the utmost commitment from all involved parties. With the ignition of the last kiln on site in June 2019 and the achievement of the guaranteed production parameters the project came to a successful and satisfying completion for Maerz and its business contributors.

Daesung MDI – Yeongwol-Gun, Gangwon-Do, Korea

Daesung MDI Inc., a company with a rich history, was founded in the 1960s and started off its business operating different limestone and dolomite mines. It continues to grow and to add new products to its portfolio.

The summer of 2014 marks the beginning of a new chapter in the company’s history, when Daesung MDI signed a first contract with Maerz Ofenbau AG for a modern coal-fired rectangular Maerz PFR kiln with a daily capacity of 200 t of burnt lime. The kiln, processing limestone with a grain size of 45 – 80 mm, was successfully installed and is now operating to the customer’s utmost satisfaction.

In the spring of 2017 the project for the second coal-fired rectangular Maerz PFR kiln with a daily capacity of 300 t of burnt lime began. This kiln processes limestone with a grain size of 25 – 55 mm.

Daesung MDI once again successfully installed the second kiln, thus achieving a milestone in its history and gaining importance in the lime industry. The plant called “Limechem Center” is up and running, operating with different limestone grain sizes and producing good quality lime.
