Chapter 9 O&M Ideas for Major Equipment Typ

Proper maintenance and operation of boilers systems is important with regard to eficiency and reliability. Without this attention, boilers can be very dangerous (NBBPVI 2001b). 9.2.2 Types of Boilers (Niles and Rosaler 1998) Boiler designs can be classiied in three main divisions – ire-tube boilers, water-tube boilers, and electric boilers.

boiler efficiency guide - cleaver-broo


Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.

How to Run a Coal Fired Boiler at the Best Efficiency .

Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.
