¾Two options were compared: co-firing of biomass with coal in the existing boiler(s), and retrofitting of an existing boiler for biomass use ¾The results indicated that the first of these options was not viable, since biomass could never account for more than a small fraction of the total fuel consumption, and the related costs are high
The initial work on this concept produced an advanced coal firing system that was capable of firing both water-based and dry pulverized coal in an industrial boiler environment. Economics may one day dictate that it makes sense to replace oil or natural gas with coal in boilers that were originally designed to burn these fuels.
Grate-firing is one of the main competing technologies in biomass combustion for heat and power production, because it can fire a wide range of fuels of varying moisture content, and requires less

The fire-tube boilers covered a steam production range of 1-20 t/hr at pressures from 10 to 20 bar. Fuels include heavy fuel oil (HFO), Sasol gas, paraffin and coal. The survey covers a total of 85 fire-tube boilers inspected over a four year period (1998-2001).
Seminar Overview. In most facilities, the boiler is the device with the most potential for disaster making boiler operation training a key part of any facility's overall safety. This two-day Boiler Operation, Maintenance & Safety course provides students with the practices and procedures to eliminate that potential.
When a boiler is not required to produce heat for those extended periods of time, most facilities will take that boiler “offline” and prepare it for a time of “safe inactivity.” The process is known as “laying up the boiler,” and it is performed to not only extend the overall life of the boiler, but also to reduce downtime and
