Thermal exhaust gas purification with raw gas preheating

As general contractor, Birk supplies a ready-to-operate thermal post-combustion plant / thermal exhaust air purification plant in horizontal design to a long-standing customer from the abrasives industry.

The post-combustion plant / exhaust air purification plant was designed for a raw gas volume flow of 1600 mn³/h from the combination of exhaust gases or exhaust air from upstream production plants / furnaces. The plant has a downstream heat recovery system from the clean gases for preheating the raw gases. The preheating of the raw gases to an inlet temperature of approx. 550°C results in only a low primary energy requirement for the operation of the combustion plant at thermal afterburning.

To further save primary energy, the afterburning system is prepared for the connection of a further waste heat utilisation system for hot water generation. The combustion plant is equipped with the latest burner generation of our industrial combustion plants developed in-house - for best clean gas values and lowest energy consumption. The combustion plant thus permits a power control range of more than 1:15.

The entire scope of supply also included part of the raw gas supply as well as the clean gas discharge into the industrial chimney system. The plant is designed as a compact version, whereby it is delivered ready for operation, i.e. electrically and mechanically pre-installed. The entire control, regulation and monitoring functions of the plant are performed by an in-house control system based on Siemens S7, which is equipped with a user-friendly visualization with touch function.
