Crown Capital Eco Management BIOMASS AS a fuel for BOILERs

5 years ago16 views

Biomass for energy often mean plant base material although can equally apply to both

animal and vegetable draw from material. Biomass is actually a biological material

derive form living or recently living organisms. Biomass chemical composition is carbon

based and is composed of a mixture of organic molecules containing hydrogen, usually

including atoms of oxygen, often nitrogen and also small quantities of other atoms,

including alkali, alkaline earth and heavy metals, metals are often found in functional

molecules such as the porphyrins which include chlorophyll which contains magnesium.

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, coal

and 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.
