Steam block boilers   :

Fire Tube

In the three – pass boiler the fire tube forms the

Combustion chamber  . The chosen diameter makes

Sure that the flame can develop and a complete

Combustion is guaranteed.

The decision whether plain or corrugated fire

Tubes are to be used depends on the diameter and

The working pressure .

The arrangement in the inferior part of the water

Space has an especially favorable effect on the heat

Exchange and the water circulation and allows a

Clear arrangement of the remaining flue gas passes.

The limited thermal load for fire tubes prescribed

By standard codes demands the installation of two fire 

Tubes at a boiler capacity exceeding 9.3 MW.
