Boiler and burner design and theory pdf

Special burner arrangements like opposed jet or tangentially fired systems can also enhance the downstream mixing in the burner, These will increase the mix- ing in the furnace and, therefore, enhance the combustion of unburnt species.

A typical boiler would use a combination of several burners.
The swirling flows of individual burners interact with each other, affecting the overall aerodynamic condition in the furnace.
It also influences the combustion process.
So they are to be arranged taking these into account.

The design of cogeneration boilers is the same as that of most industrial boilers.
If the steam demand is high, it is economical to drive as many boiler auxiliaries as possible on steam.
The capacity of a cogeneration plant is usually dictated by the steam requirement.
