Modern power plant chimneys can suffer from positive pressure especially in hot climates. Exponent has developed a design modification for the New Chimney Design to eliminate this problem.
It is more and more important for coal fired power stations in Europe to maximize their operational efficiency and minimize their emissions. A study by STEAG shows that under some conditions, eliminating reheat and modifying the chimney for wet stack operation can bring economical and environmental advantages.
A group of German specialists designed and engineered a concrete chimney, protected directly by the PennguardTM Block Lining System, known as the New Chimney Design. This report compares detailed chimney designs with traditional concrete chimneys with brick, steel and FRP flue and the New Chimney Design.
The report entitled “Performance of PennguardTM Lined Tall Reinforced Concrete Chimney Structures in the 2010 Chilean Earthquake“ summarises the findings of a field study to investigate the performance of four tall reinforced PennguardTM lined concrete chimneys which were subject to significant ground shaking during the 2010 Mw8.8 Chilean earthquake event.
The report entitled “PennguardTM linings, seismic test performance“ describes a laboratory study into the tolerance of the PennguardTM Block Lining System for crack formation in a concrete substrate.
Wet stacks have gained popularity worldwide as the use of Flue Gas Desulfurization (FGD) systems has increased and many owners have decided not to reheat the water saturated flue gas emitted by the wet FGD system.
The report entitled “PennguardTM stack liner material for Wet Stacks – An evaluation” describes a laboratory study into the properties of PennguardTM linings, when used in water saturated, Wet Stack environments.
A number of power plant chimneys have suffered from severe fire damage over the past 20 years. The risk of catastrophic fires is even more relevant today as large amounts of combustible construction materials are used in Flue Gas Desulfurization (FGD) systems.
This report describes a laboratory study into the temperature cycling resistance of the PennguardTM Block Lining System, when using Type 55 PennguardTM Blocks.
In 2014, two experts of TÜV Rheinland visited Kusile Power Station, South Africa, during a large scale PennguardTM installation to perform a safety audit.
