EKONOMİZER ÖZELLİKLERİ
Today’s competitive conditions have led companies to use high-cost energy at an optimum
level. Waste flue gas is evaluated to obtain hot water and hot air from the gases thrown into the
atmosphere, as in the RAM machines used in the textile industry.
In high efficiency boilers, the boiler efficiency varies between 85% and 92% in instant
measurements. In particular, the use of waste flue gas generated in steam, water and hot oil
boilers and the waste hot water energies in the textile sector have a great contribution to the
production costs and the country’s economy.
The economizer in industrial boilers is an investment tool that is calculated to bring savings of
3 - 8% during the planning stage and is thought to be even more beneficial in practice. Systems
made by considering process values pay for themselves in a short time.
The main issues to be considered in flue gas economizer applications are the properties of the
gas and its condensation temperatures. In case of condensation in flue gases, acid occurs and
all surfaces with condensation must be made of acid-resistant materials.
If the minimum pressure loss is aimed, condensation is not preferred and economizers can be
designed from carbon-steel materials. Since the economizer lowers the flue gas temperature,
the unnecessary excess air in the flue gas is cooled and discharged. In this way, the efficiency
loss caused by the increase in the excess air coefficient is significantly reduced.
