Industrial Chimneys

We have an abundance of experience executing steel and concrete chimneys. We design, project and construct chimneys for power plants, refineries, paper mills and all other types of industrial plants.

Industrial chimneys are vertical constructions created to reduce the impact of greenhouse gases and other industry substances on its immediate surroundings. These stonework (brick), concrete, or steel structures are used to eject gases generated by industries after completing their production processes. The objective is to reduce the impact these sub-products have on the environment and on humans. Some reduce levels of pollutants while others reduce gas the temperature of the gas.

Types of industrial chimneys

Although there are basic types of chimneys and stacks, each is designed differently and serves a specific purpose. Their nozzles are calculated based on parameters such as the type of gas circulating inside them (N , water vapor, CO , NO , SO , etc.) and physical factors such as the flow rate, gas temperature or gas speed. Different combinations bring about unique conditions for each plant, making it impossible to use an ad hoc design from one plant at another one.

Vertical chimney constructions are used in a wide range of industries such as glass production (Tudela, 91 m), refineries (Guadarranque, 85 m), diesel plants (Los Guinchos, 39 m), paper mills and power plants (Soto de Ribera, 200 m), among others. It is impossible to summarize all the different execution processes for foundations, flue lining, main materials (brick, steel, concrete) and height.

A common characteristic of industrial chimneys is that they must be designed to comply with environmental protection decrees and must maintain low levels of pollutant emissions. In order to comply, constructions can be up to hundreds of meters tall, as is the case with the Andorra chimney (343 m). This includes greenhouse gases and particles whose ground-level toxicity may be harmful to human health, and both factors are related with Sustainable Development indices. Chimney height is determined to help dispersion, which is why some are so tall and are lifted using slipform.
