Introduction to a Real Boiler System - continued.Boiler: Section 5This section shows the induced draft fan (ID Fan). The purpose of this fan is to draw air from the main furnace we saw in Section 1. This fan provides much of the energy required for the flue gas to move from left to right. This fan sucks flue gas through the systems located on the left hand side and forces it into the stack (chimney). This figure shows the boiler stack (chimney). The purpose of the stack is to create a draft through the system and release the flue gas at a high elevation so that it can safely disperse through the atmosphere. |

If the figure provided here does not make sense, go back to the block diagram of this system. Much of the technical matter provided here has not been discussed with you. It will be discussed in later sections. This section is designed to provide you with a brief overview.
