REASONABLE PRICED FUEL FOR THE CEMENT INDUSTRY
LEP Lignite Energy Pulverized by Rheinbraun Brennstoff (RBB) is a reasonable priced source of energy for the cement industry. It is obtained by refining Rhenish lignite. We can provide a highly secure supply as we mine and produce the product ourselves. Thanks to long-term supply agreements, Lignite Energy allows energy-intensive sectors to calculate their costs years in advance.
RBB has developed unique expertise in industrial processes specific to the cement sector over the course of decades of working together with the cement industry at a corporate and individual level. This expertise led us to create a high-quality, low-sulphur, low-ash fuel for the energy-intensive rotary kilns used in the cement industry during clinker production and to dry granulated slag.
NET CALORIFIC VALUE
RBB’s LEP contains a high proportion of volatile matter, as well as a consistent grain size and a consistently low water content. This ensures a near-constant net calorific value in rotary kilns, leading to optimum burning characteristics.
In contrast to oil, gas and hard coal, LEP as an energy source available on our doorstep is a reasonable priced source of energy and, given the consistent decline in demand for primary energy, a sensible just-in-time alternative instead of grinding your own hard coal. Long-term supply agreements mean energy costs can be calculated reliably in advance, making plants more profitable.
SIMPLE AND SAFE TO USE
LEP is easy and safe to use in closed systems. In fact, it is just even simpler to use than hard coal. The LEP arrives by road in a silo, or by rail in a closed tank wagon.
Rotary kilns can be converted to run on LEP without the need for major expenditure, allowing you to benefit from low fuel prices while continuing to use your existing plant. The investment will pay for itself in a few short years. The limited space required and high control speed bring other operational benefits, too. You can rely on RBB’s expertise if you decide to convert. We will be at your side from planning right through to implementation.
LE Lignite Energy Products
LE Pulverized is a low-sulphur, low-ash fuel used in combustion plants to generate process heat and in low-pressure and high-pressure boilers to generate process steam. Pulverized fuel firing systems save space and feature a high control speed. LE Pulverized is extremely easy to use in a closed system. Ash is disposed of by RBB.
LE Grained is a specialist product for use in the circulating fluidized-bed. The low-sulphur, low-ash fuel is delivered by road in a silo or by rail using a tank wagon, and then handled using a closed system. The high level of lime in the ash means that sulphur emissions associated with the combustion technique are naturally limited without the need for any additional measures.
LE COMPACT are lignite briquettes for industrial use, used in traditional travelling grate boilers. This proven technology is cost-effective, easy to use and guarantees low emissions. Waste materials can be used to produce thermal energy. Delivery is by road, rail or ship.
