The heating value of coal is necessary for its usage in power generating. This is tested experimentally, although theoretical models have been used to forecast the heating value; either lower heating value or greater heating value. The same approach has been used to biomass, which is being promoted as an alternative for coal or as a co-fired fuel. Biofuel production was seen as a significant countermeasure for lowering anthropogenic CO2 emissions, removing the worsening greenhouse effect in the atmosphere, and slowing global warming. Thermochemical conversion is thought to be the most effective method of generating biofuels from biomass, with the least potential for global warming. The torrefied biomass is used for making biomass material into a useful energy and it also enhance the property of that material by torrified it.
