How to Run a Coal Fired Boiler at the Best Efficiency
Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.

Soot blowing management - STEAG System
SR::BCM for coal-fired steam generators . Soot is a natural byproduct of burning coal. It gradually soils the heating surfaces in coal-fired plants, which inevitably reduces the boiler's efficiency. The obvious solution is to routinely clean the surfaces – a time-consuming and costly process that sometimes isn't absolutely necessary.

Chapter 21 - Boiler Fireside Deposit and Corrosion
2020-4-7 · Generally, units used to fire coal have sufficient soot blower placement for adequate removal of properly conditioned deposits. Natural gas-burning units generally do not have the desired soot blowing equipment. It is advisable to contact the manufacturer so that the proper number of soot blowers and their location can be specified.

AB Catalyst | Cleaner Coal Combustion
Decrease the frequency of unscheduled downtime, maintenance and repairs by using AB Catalyst to minimize slagging and fouling. AB Catalyst reduces the cohesive strength of the ash, so that solid ash does not melt and fuse to surfaces inside the boiler. The ash becomes drier and more friable for easy removal with normal soot blowing.
