Exhaust air treatmentand CO2 recovery

RBU has a diverse range of shut-off and control solutions for gases and dust arising during steel production. This includes hydraulically-operated “corner valves”, which, depending on the quality of the gas, alternately guide large quantities of gas to a gas storage tank (gasometer) or a flare stack as part of a continuous control process. Gas-tight goggle valves are also included in the range of products. RBU provides system solutions, including hydraulic units.

Cement industry

Always on the safe side

Always on thesafe side

RBU dampers and valves are used in many areas of a cement works for shutting off and controlling extremely dust-laden process gases, as well as for shutting off pourable solids. In the tertiary air area, valves are used in temperature ranges up to 1100°C. The extremely abrasive properties of the raw materials and ever greater nominal sizes require special solutions which RBU has been successfully supplying for more than 25 years.

All requirementsindividually met

All requirementsindividually met

Thermal processes are varied and often set high requirements for the furnace system and the process technology. Adherence to stable parameters when it comes to atmospheres and temperatures is imperative, particularly for high-quality products for which product properties must be replicable. RBU provides an optimal solution – tested over many years – while observing all the specifications for any control task or shut-off task at temperatures of up to 1100°C.

Protected systems formaximum security

RBU dampers and valves are used in a wide variety of areas within a power station for safely shutting off and controlling process gases in the furnace area, and as safety shut-off devices in the exhaust gas, coal dust feed and ash removal areas. In the coal dust handling area, explosion-protected systems are absolutely mandatory

Exhaust air treatment

Optimisation and precision thanks to RBU products

Optimisation and precision thanks to RBU products

For thermal exhaust air treatment, contaminants contained within the exhaust air are incinerated at temperatures in excess of 700°C, leaving behind almost no residue. RBU shut-off dampers and control dampers, which guarantee optimum efficiency and residue-free contaminant incineration at temperatures of up to 1100°C thanks to precise control and secure sealing, are used to optimally control the incineration temperature and gas flow.

Premium quality for a safe future

Premium quality for a safe future

Domestic waste, bulky waste and commercial waste are thermally treated and recycled in waste incineration plants. Residual waste is converted into energy in the form of steam, while bottom ash is processed with scrap metal. Robust, wear-resistant RBU dampers are used for process gas control as a whole. RBU solid material shut-off valves are used to successfully discharge the ash.

RBU dampers in ship engineering

RBU dampers in ship engineering

The reduction in the sulphur content in ship exhaust gases is a fundamental requirement of the International Maritime Organization (IMO). RBU dampers ensure environmentally friendly ships on the world’s oceans. We have developed special exhaust air dampers for the exhaust gas flow of ship engines to increase the energy efficiency by preserving the heat. Without these dampers, the flue is open to the top so that the boiler plant and main engine cool down after they have been switched off. The RBU dampers prevent this. As soon as the burner stops and the fan switches off, the damper closes automatically. Thus, the combustion chamber does not cool down so quickly and the temperature is kept longer in the system. The advantage of our technology: significant fuel savings! All dampers have a type approval of the DNV GL for use on sea-going ships. In addition, special RBU control and shut-off dampers for exhaust gas cleaning systems (scrubbers) on ships have been used successfully for many years. RBU control dampers: one or two wings, swing-through depending on the requirements, for continuous control or with sealing strips for a tight seal when closed. RBU safety dampers: with self-releasing counterweight in the event of a fault – safe opening / closing of the damper under any condition. RBU double shut-off dampers with sealing air station: gap warm air application for excess pressure – guarantees that no exhaust gas is leaking. Optionally available with inert air.
