Gangyuan Co. Doo Smederevo, Serbia, placed an order with Maerz Ofenbau AG for the supply of engineering, license, know-how, equipment as well as technical assistance services during erection, commissioning and start-up of a Maerz PFR lime shaft kiln at the client’s Kucevo lime plant. The new kiln of the circular type R4P will process limestone with a grading of 60 to 110 mm and will produce 600 tons of burnt lime per day.

Natural gas will be used as fuel, with an option to also use coal in the future. The kiln will eventually be operated with either 100 % natural gas, 100 % coal dust or a mixture of both fuels.

Maerz’s equipment supply comprises the following main items:

• Process air blowers with motors
• Electric, measuring and control system for the lime kiln
• Firing system for natural gas, including the start-up burner equipment
• Hydraulic equipment
• Limestone skip hoist winch, including the pertinent electrical measuring and control equipment

The client will perform the erection of the plant with local contractors and Maerz will act as technical advisor, if so requested by the client. Maerz’s specialised technicians will assist with hot commissioning and acceptance test runs on the lime kiln and the associated equipment.
