Condensation technology is an effective method in converting of natural
gas to useful energy by combustion. The latent heat of water vapor in flue gas
is incorporated to the system and the thermal efficiency is increased by the
use of this latent energy. The condensing boilers discharges flue gas at low
temperatures while operating.
Condensing boilers are operate with low flue gas temperatures. Mixing of the air and gas used in the energy production to obtain an efficient combustion before get inside the combustion chamber is named as premix.
Premix systems provide lower emissions values (NOx-CO) after combustion.
Synchronized operation of more than one condensing boiler in central
heating systems is called CASCADE system. In cascade systems, the boiler that
manages the system is called MASTER, and the boilers working in connection with
it are called SLAVE. The master boiler operates all boilers in the system
according to the principle of equal aging and ensures that the service life of
all boilers is extended. The biggest advantages of the cascade system compared
to conventional systems are:
In case of
malfunction or maintenance, operations in the relevant boiler can be performed
without the need to stop the system.
In case of a
mechanical failure in the master boiler, the master boiler continues to manage
In the event of a
malfunction in the control system of the master boiler, one of the slave
boilers provides control of the heating system as a master by changing the
