New chimney design Gains from use od a diffuser

Hadek Company developed with the support of the Expert Office Exponent a new chimney type based on the concrete windshield protection by a Pennguard™ lining. The technology denoted as the New Chimney Design (NCD) had been used in power stations in many countries. Due to this success Hadek commissioned to Exponent a new study on gains from the use of a diffuser. The results prove that the flue gas draft can be substantially increased without an increase in the overall cost.
