Boilers: Economic Change From Coal to Biomass

The transport cost per unit of energy produced is much lower for torrefied and pelletized biomass than for bulk unprocessed biomass, due to the energy density and physical compaction. The pellets can be mixed with the coal before pulverizing for a pulverized coal boiler, or fired mixed, or separately in other boiler types.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7-2,000 kPa or 1-290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
