The economic development of one country is dependent upon the ability of the authorities to set up a highly suitable, competitive and reliable electricity sector. Why is natural gas better than coal boilers?

Only when there is extreme environmental pressure or substantial reduction in loads that conversion from coal to 100% natural gas is possible.

Not until the 20th century until natural gas was used for production of energy, it was dismissed as a useless byproduct of crude oil production until then. But now natural gas accounts for 23 percent of the world’s energy consumption and still growing. The International Energy Agency predicts that the demand for natural gas will grow by approximately 44 percent through 2035.

Natural gas is the cleanest-burning conventional fuel not to mention it has been one of the most economical energy sources. It is an environmentally friendly and efficient source of energy. It produces lower levels of greenhouse gas emissions than heavier hydrocarbon fuels such as coal and oil. Natural gas fuels electric power generators, heats buildings and is used as a raw material in many consumer products, such as those made of traditional plastics. However, natural gas has never been a cheaper fuel than coal.

Coal is one of the longest-used and is considered as the most abundant fossil fuels on Earth. Coal mining has been going on since then 17th century. Coal burning boilers have also been around for a long time, and while they may not always be popular, these machines have some definite advantages in terms of costs and simplicity.

Because it is the most abundant it is the cheapest form of fossil fuel to burn. But coal boilers on the other hand have harmful effects on the environment and human health. Its emissions contain sulfur combines with air to create the poison gas sulfur oxide. When this gas releases into the atmosphere, it causes polluting rain. Extracting coal from mines further damages soil and water resources, adding to the disadvantages of using coal burning boilers.

While coal prices are expected to remain stable natural gas prices are expected to increase as higher cost natural gas reserves need to be developed to meet growing demand and offset losses from depleting gas wells. On the other hand, natural gas based technologies have a capital cost advantage.

Whatever the costs may be, don’t you think it is better to use natural gas rather than the coal boilers? Even though natural gas is more costly than coal boilers it is less harmful to the environment and to human health. It is always better to take into considerations the things that are more important than money. It is not wise to be thrifty over something that in a long run would back fire on you and worst your kids. Long term effects of coal boilers are scarier than the costs in terms of money that it will bring us today. Environmental effects and health issues will sure be more costly in the future.

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 willdeplete. 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.

Crown Eco Management

Independence 
Although Crown cooperates with various organizations, we maintain our being an independent body, free from control of any particular government, state or institution and unimpaired by their own respective interests.

Public Awareness 
Educating and enlisting the public to secure and maintain the quality of our natural resources is one of our priorities. We believe that by having well-informed and knowledgeable people, especially in the government sector will make it possible to maximize the benefit of existing legislation, and creating more, in order to preserve our e nvironment.

Sustainability 
A long-term responsibility of preserving resources for future generations that cover economic and environmental factors. Sustainability enables the environment to be productive and diverse enough to host humanity along with other living organism through effectively managing human impact on the ecosystem based on information provided experts.

Taking steps towards sustainability is a difficult challenge as it entails international and local law, individual lifestyles and urban planning. Measures should be implemented on re-evaluating work practices, altering general living conditions and making new technologies in order for a sustainability goal to be accomplished.

Accountability 
Crown Capital Eco Management also aims to raise awareness of our society getting trapped in progress with only the short-term concerns in mind for failure to protect and conserve our natural resources could lead to irreversible consequences not only in the future civilization but to the whole ecosystem itself.
 

Along with the recognition that the environment is needed for us to survive is the realization that we must answer for its sustainability and be responsible for managing the great resources we are entrusted with.

Independence 
Our group strives to make every sector of our society, especially the public, recognize the need for transparency in what is and will be happening to our natural resources in the future. Every individual leaves his mark in the environment and unfortunately, not all of us leave a beneficial one. Therefore, we must be consistent and united in our efforts as a civilization to preserve our nature.
