FIRING DRYING UNITS AT A LOW PRICE
LE Lignite Energy by Rheinbraun Brennstoff (RBB) is a low-cost source of energy for direct-fired drying units. LE Pulverized makes companies in energy-intensive sectors immune to volatility on the gas and oil markets. Companies can calculate their energy costs for the process heat required in industrial drying processes well into the future, thanks to prices that remain stable for prolonged periods and long-term supply agreements.
RBB has developed unique expertise in industrial drying processes across a wide range of different sectors over the course of decades of working together with its customers at a corporate and individual level. RBB develops tailor-made direct firing solutions for a range of applications, including in the construction industry, the feed industry, and for plaster and expanded clay producers.
The benefits of these solutions will help to give our customers a lasting competitive advantage.
CONSISTENTLY HIGH NET CALORIFIC VALUE
Its high level of volatile matter, consistent grain size and consistently low water content give LE Pulverized a high and constant net calorific value. Optimal burning characteristics make for energy-efficient industrial drying processes.
SIMPLE AND SAFE TO USE
LE Pulverized is easy and safe to use in closed systems. In fact, it is just as simple to use as an oil-powered system.
HIGH CONTROL SPEED
Combustion plants for LE Pulverized have a high control speed. That means they are also ideal for drying raw materials with various feed qualities.
OUTSTANDING PROFITABILITY
No other fuel is so cost-effective. Long-term supply agreements and constantly stable prices mean energy costs can be calculated years in advance.
PROFITABLE FROM 2 MW
LE Pulverized is profitable from a furnace thermal rating of 2 MW thanks to its low price.
MEETS STATUTORY EMISSIONS GUIDELINES
The low ash and sulphur content of LE Pulverized makes compliance with statutory emissions an easy task.
UNBEATABLE SECURITY OF SUPPLY
As a source of energy available on our doorstep, Lignite Energy stands out thanks to its unbeatable security of supply, guaranteed by RBB and the production plants it owns. RBB ensures flexible just-in-time delivery with three production sites, two handling terminals in Ulm and Brandenburg an der Havel and our in-house logistics unit.
PROVEN TECHNOLOGY
WITH A LOW SPACE REQUIREMENT
LEP furnaces require little space. Existing heating oil or natural gas-fired combustion systems can be converted to Lignite Energy using standardized parts and without major expenditure. The investment will pay for itself in a few short years.
LEP combustion units basically consist of a burner along with standardized silo, feeding and conveyor units. The smallest pulverized fuel silo unit has a capacity of 120 m³. That equates to around 60 tonnes of LE Pulverized, which itself produces the same amount of energy as almost 40,000 litres of heating oil. This size of silo is often sufficient to ensure a secure supply of fuel. If demand is particularly high, larger silos, or several silos, can be installed.
LE Lignite Energy Products
Le Pulverized
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
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
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.
