Fuel has nothing to do with Climate Change, Climate Change is the direct consequence of the combustion (a process) of fuel, which exacerbates Environmental Degradation.
Climate Changes all the time, particularly during changing seasons. However, the Environmental Degradation is exacerbated by the USE & ABUSE of Fuel, & it has more far-reaching consequences, than so called Climate Change.
USE of fuel can be defined as where fuel is used as source of mechanical power to satisfy a Human Need. Example: fossil fuel combustion to run a school, a hospital, or to keep people in a house hold warm, …….
ABUSE of fuel can be defined as where fuel is used as source of mechanical power to satisfy needs which cannot be considered as a Human Need. Example: manufacturing of a an Aircraft Carries , & use fuel to send them to war with other manufactured war machineries like: Aircrafts, Tanks, Ammunitions etc. Or using fuel in internal combustion engines for Motor Racing – Formula 1, or using fuel for manufacturing automobile to be used in chaotic transportation system, or using fuel to run automobile with full knowledge of knowing that, the problem with the automobile is, they are the central component of a fuel wasting, environment-spoiling, chaotic transportation system, & knowing that, each gallon of gasoline (petrol) burned by a car’s engine produces about 9 kg (20 lb) of CO2.
Internal-combustion engines operate on the principle of compressing the fuel & air, burning it at a pressure above that of the atmosphere, & then expanding the products of combustion into the atmosphere. Cars, locomotives and aircraft are propelled in this way. It is therefore important for the engineer to know the properties of available FUELS and of their combustion products, & to be able to calculate the temperature which can be reached in the combustion chamber & the maximum work that can be obtained from a given quantity of fuel. To this end, the thoughts has to turn into chemical thermodynamics.
To be able to understand the Environmental Degradation understanding of basic thermodynamics, & Chemical Thermodynamics is the prerequisite:
The Chemical Thermodynamics is the subject which is vital to other branches of engineering also. For example, the operations of the metallurgical industry can be understood only through knowledge of the interactions between the fuel used in smelting the metal-bearing ores, and the various metals which make up an alloy.
The Chemical Thermodynamics is even more important for chemical engineers, who design the processes with the aid of quantitative knowledge & try to find out, what are the possible reactions; how pressure, temperature; changes in the material composition, & the Energy Changes for a process can effect environment.
The phrase Climate Change is a phrase devised by so called “Renewable Energy” industry with prime objective of selling manufactured Wind Turbines & Photovoltaic cells….. etc.
Basic Combustion Chemistry In combustion (a process), fuel gives up its chemical energy by a chain of reactions that changes the chemical energy in fuel into thermal energy, measured by the Heat Content in the Fuel expressed in BTU/lb in Imperial & US customary measurement systems or kJ/kg in the International System of Units. With hydrocarbon fuels the by-products of combustion process are always Heat, carbon dioxide & water vapour. Carbon dioxide is produced by the carbon in fuel. Water vapour is produced by the hydrogen. Thus, for example, natural gas produces a large amount of water vapour, & coal produces little. However, water that contaminates oil & coal, often in large amounts, ends up as water vapour in the flue gases. In perfect combustion, no oxygen would be left in flue gases, because any excess oxygen is deadweight & would absorb combustion heat. By the same logic, the presence of oxygen is an excellent indicator of boiler or engine efficiency. Similarly, the quantity of carbon dioxide in the fuel is also used to measure boiler efficiency. The sulphur in fuels burns to form sulphur dioxide. This produces a relatively small amount of thermal energy, but it causes major problems.
On planet earth on a daily basis there are literary millions & millions of combustion occurring, each producing by products & heat (thermal energy); & each combustion acting like a volcano degrading the Environment & speeding up the process of Environmental Degradation at faster rate; so Environmental Degradation is an inevitable process, which needs management, 1st step is to have an International “policy for use of fuel”; defining what is meant by “Use of Fuel” & “Abuse of Fuel” & how to control abuse of fuel.
Simply to slow down the Environmental Degradation; reduce total number of combustions this will reduce the amount of CO2 , & heat emmision.
