BIOMASS AS a fuel for BOILERs - Crown Capital Eco Management Indonesia

There are five basic categories of material of biomass such as:
•Virgin wood- from forestry, arboriculture activities or from wood processing.
•Energy crops- high yield crops grown specifically for energy applications
•Agricultural residues- residues from agriculture harvesting or processing
• Food waste- from food and drink manufacture, preparation and processing, and post-consumer
waste
•Industrial waste and co-products- from manufacturing and industrial processes.
The question is how are we going to use this biomass as a fuel for boilers? But what is
a boiler in the first place? A boiler is defined as “a closed vessel in which water or other
liquid is heated, steam or vapor is generated, steam is superheated, or any combination
thereof, under pressure or vacuum, for use external to itself, by the direct application of
energy from the combustion of fuels, from electricity or nuclear energy.”
Let us then go back to the previous question, how are we going to use this biomass as fuel for
boilers. Nowadays, the prime sources of energy in the world are oil, coaland natural gas. But these
natural sources of energy has their end too, unfortunately it is already anticipated that within the
next 40-50 years these sources of energy will deplete. Worst is, it is also expected that from these
sources lies consequences due to their emissions such as global warming, acid rain, urban smog. Due
to this fact the world is trying to utilize new sources of energy, there are some renewable energy
sources that can replace harmful energy sources. The solar, wind, biomass etc are energy sources
which are less harmful to the environment but can only be use in a suitable way. Biomass is one of
the earliest ever discovered sources of energy but only comes with specific properties. It was then
discovered that utilizing biomass in boilers offers many economical, social and environmental
benefits such as financial net saving, conservation of fossil fuel resources, job opportunities
creation and CO2 and NOx emissions reduction.
However, care must also be taken for consideration. Although biomass can be good in
some point there are also disadvantages such as: environmental impacts of biomass
such as land and water resources, soil erosion, loss of biodiversity and deforestation.
Problems associated when burning biomass in boilers are fouling, marketing, low
heating value, storage and collections and handling. The future of biomass in boilers
depends upon the development of the markets for fossil fuels and on policy decisions
regarding the biomass market.
