for Schaefer Kalk in Germany: a new Maerz PFR kiln replaced two old mixed fired single shaft kilns. Here, the challenge was not only to keep the existing foundation as well as the charging system, but also the extremely re-stricted space for erection in this brownfield job. Another project we completed on sched-ule and within budget.
area, including PFR Kilns, single shaft kilns, high temperature kilns, and multiple hearth furnaces, steadily increased with the majority of them being built in Iran. The latest order for Maerz in Iran was in 2005 for Foulad Afza Sepahan Co., Esfahan, which ordered two Maerz PFR Kilns with 250 tpd capacity each, to produce burnt dolomite
Vertical lime kiln, just like its name, the shape is erect. It is used for calcination limestone. Due to has low energy consumption, less cover area, less investment, wide applicability fuel, and more advantages, the vertical lime kiln is also widely used in metallurgy, construction materials, calcium carbide, Nanometer calcium carbonate, aerated concrete, sugaring, etc.
Maerz also offers other kiln types for specific purposes. For instance the ANNULAR SHAFT KILN for all applications requiring a continuous stream of exhaust gases and a high CO₂ content in the exhaust gas.
The maerz kiln is provided with vertical twin shaft kiln (3,4). Each vertical shaft kiln (3, & 4) have a provision of combustion gas inlet point (5, 5) and a level sensor (6) and a lance tip (7), a plurality of lance point (8) as shown in fig-2.
Typically the kiln is driven at speeds of 0.5 to 2 RPM, often with variable speed arrangements. Typical transit times for the lime through the kiln are from 1.5 hours to 4 hours under normal operating conditions. This is set by the speed and by the slope of the kiln, which is …

shaft kiln was really well adapted to the production of low-reactive burnt lime. This is why Maerz de- signed, constructed and patented a new single-shaft kiln, the HPS kiln (high-performance shaft kiln). It consistently delivers low-reactive burnt lime with the best quality and the highest energy efficiency. Maerz HPS kilns feature:
The special geometry of this kiln and the special charging of the feed material guarantee ideal heat distribution, even when processing small-grained stone. The principle of the PFR kiln, i.e., the calcination of lime in one shaft and the preheating of the stone with the hot kiln gases in the other shaft, is also used in the Finelime® kiln.
Modern kilns are typically one of three designs: single shaft, annular, or regenerative. Each respective design is progressively more energy efficient, but all are based on a countercurrent flow of hot air rising from the burners in the calcining zone through the downward material flow.

1 HEATING UP THE KILN LINE . Before firing the flame the pressure at kiln hood has to be adjusted to 0 mbar, in case of ± heavy oil combustion pay attention to an oil temperature of at least 120°C (spray viscosity2°E). The firing of the flame takes place with a firing device or with the traditional fuse cord.
This E2 Maerz 2-shaft lime kiln is coal fired and has a capacity of 150 tpd. Maerz supplied engineering and key equipment. With Maerz technical assistance and experienced Chememan personnel, the lime kiln was successfully commissioned and ignited in June 2019 and is now in commercial operation.
