Carbotechnik Energiesysteme GmbH

We build hot gas generators and industrial combustion chambers on the basis of many years of research and development. Our hot gas generators can be used for drying a broad range of products such as cement, limestone, animal feed, grass, etc.

The burner is primarily designed for the combustion of pulverised materials, such as lignite, biomass, sludge, etc. But gaseous and liquid fuels can be used as well. Depending on the design, automatic switching between fuels is possible without modifications and the associated downtime. The use of alternative fuels allows for considerable cost savings and long-term planning. In regions where lignite is mined, pulverised lignite is a cost effective and environmentally friendly alternative.

Even the largest hot gas generator can be built without refractory liners. They are durable and completely impervious to rapid temperature changes. The use of return gas is possible and, in addition to lowering fuel costs, also saves filter costs.

We are able to delivery the complete system as a turn-key solution, offering you a maximum degree of planning reliability.

Advantages:
 

• Free choice of fuel (atomized, gaseous, liquid) - also in combination
• Instant power demand and rapid load changes
• Compact design
• Position (horizontal/vertical) selectable
• Low-maintenance and high system availability
• Use of process air/return air for lower fuel consts and filter costs
• Thermal disposal of climate-damaging waste gases
• Ensured shortfall of all emission limits
• Self-contained PLC controll with a data interface for BUS connection in an existing process control system

The Carbotechnik dosing system is designed for the continuous dosing and conveying of pulverised fuels and bulk materials, such as coal dust, limestone dust, wood dust, kaolin dust, bio dusts and other pulverised materials in combustion and processing systems. The amount of dust to be delivered is continuously adjustable to a very high level of precision and is conveyed pneumatically by a carrying air flow.

The technology makes it possible to deliver a uniform, constant supply of special fuels in compliance with the most current safety and firing technology requirements, and to generate a low-pulsation combustion process.

Advantages:

• highly accurate dosage and wide range of dosage
• uniform and pulsation-free transportation
• reliable and low-maintenance operation
• flexible quantity and capacity of the built-in dosage unit in a dosage machine
• self-contained PLC controll with a data interface for BUS connection in an existing process control system

By using the unique technology of our pulse burner systems, boiler systems can be fired with pulverised lignite.

The most economical and efficient option for our customers to realise their heat, steam and electricity supply. They value our know-how and our experience from many installed systems. And the systems are implemented exactly according to our customer requirements. A secure supply of energy and long-term planning of energy costs with domestic pulverised lignite are key decision-making reasons for selecting our technology.

Thanks to our many years of experience in the combustion of pulverised materials, we are the market leader in the field of pulverised lignite fired boiler systems. Naturally, the strict emission values according to TRD are met. The entire system operates without constant supervision in accordance with TRD 604.

With our technology, the lean and/or climate-damaging process gases often generated during production processes can be utilised to produce thermal energy. In addition to the cost savings achieved by eliminating the expense of disposing of harmful process gases, added value is also produced through thermal utilisation.

Besides supplying a turn-key solution, the system can also supplied through "savings contracting". This innovative energy supply concept guarantees you a lasting reduction in energy costs and doesn't require any investment expenses.

Advantages:

• long-term security of low fuel costs
• boiler efficiency higher than 93%
• low-maintenace and high system availability
• economical operation without constant supervision (BOB according to TRD 604)
• clean and dust-free handling
• environmentally sustainable standard fuel (pulverised lignite) in accordance with the "Technical Manual for Clean Air" (TA - Luft). No additional measures required beyond flue gas de-dusting
• thermal utilisation of climate-damaging waste gases
• optional contracting model for cheap energy without high investment costs

Depending on customer and individual requirements, we specialise in storing combustible dusts such as pulverised lignite.

Carbotechnik silo systems are the most economical solution for storing pulverised lignite in compliance with the strict ATEX safety standards. The technical safety recommendations from Rheinbraun and Vattenfall Europe are also considered during design of the silo.

Silo equipment for explosion hazard areas according to ATEX:

• Pneumatic filling from delivery vehicles
• Cooling of the pneumatic conveying air (intercooler)
• Filter technology
• Fill level measurement
• Temperature monitoring
• Blowback flaps
• Product unloading via rotary feeder
• Loosening of the material in the silo cone for reliable unloading
• System for rendering the silo inert
• CO measurement
• Fully wired
• Control system for all operating sequences, option for connection to a
  higher-level PCS.
• Turn-key installation and commissioning
