Economizer

Koneko Economizer is a system which provides FUEL SAVING and BOILER EFFICIENCY in boilers, steam boilers, hot water boilers and hot oil boilers by using the heat of the flue gases in order to increase the temperature of the feed water (and fluids) in the system.

With use of Economizers, it is possible to achieve 5 - 10% efficiency by reducing the temperature of flue gases to the level of operating conditions.

The payback amortization of economizers varies depending on such factors as the capacity of the system, efficiency of the boiler, and its application areas. The details on the pay-back period are provided at the back of this catalogue. The pay-back period of an efficient economizer varies between 3 – 6 months.

The bypass channel for flue gas is located within Koneko Ekonomizer. Thanks to the leak-proof valve mechanism, it controls the direction of the flue gas, minimizing the energy costs and environmental pollution.

Economizer

Feed water is heated by flue gases within the economizer before entering the main heating surfaces of the boiler. In this way, the gases inside the water can exit much easier, as the temperature difference between water sent to the boiler and the water which is being heated is reduced. This increases the thermal efficiency of the boiler. The working principle of the KonekoEconomizer for steam boiler is summarized in the graphics below.
