Thus, the substances classified as fuel must necessarily contain one or several of the combustible elements : carbon, hydrogen, sulphur, etc. In the process of combustion, the chemical energy of fuel is converted into heat energy. To utilize the energy of fuel in most usable form, it is required to transform the fuel from its one state to another, i.e. from solid to liquid or gaseous state, liquid to gaseous state, or from its chemical energy to some other form of energy via single or many stages. In this way, the energy of fuels can be utilized more effectively and efficiently for various purposes. Objectives After studying this unit, you should be able to • describe the classification of fuels, • explain the various types of fuels and their characteristics, and • know their applications in various fields. -

Aviation emis- sions have also grown, despite improvements in fuel efficiency. These emissions affect the radiative balance of the Earth system by changing concentrations of greenhouse gases and their precursors and by altering cloud properties. -

Outline of Solid Fuel Manufacturing
Technical Information Sheet 1. Name of technology Biomass Waste Fuel (BWF) Manufacturing Technology Complete recycling of waste oil (waste ink, waste paint, etc.) which has been considered difficult for recycling and simply incinerated. 2. Type of technology A patented original treatment system (Patent No. 5078628) to manufacture BWF as an alternative fuel to coal 3. Description of technology [Objective and application of technology] Our original treatment method and facilities enable waste oil, for which incineration has been the only treatment method, to be recycled to BWF with higher combustion efficiency than coal and thereby contributing to the reduction in environmental impact by accelerating the recycling of various kinds of waste. In particular, BWF for cement factories enables combustion residue from incineration plants and oil mud from oil-water separation plants to be fully recycled, provided that BWF is used in appropriate plants with facilities for burning general coal. In our BWF manufacturing process, we receive materials after carrying out preliminarily sample inspections for thoroughly confirming material composition (to eliminate substances with hazardous properties such as heavy metal contamination). Also, we treat the materials using a reliable safety management system including special fire prevention equipment such as a nitrogen generating devices and sprinklers with twice the capacity generally required.

Health Problems and Burning Indoor Fuels
American Thoracic Society PUBLIC HEALTH | INFORMATION SERIES Health Problems and Burning Indoor Fuels Household air pollution means that the quality of the air inside your home is not healthy. There are a number of things that can pollute the air indoors. A common source of indoor air pollution worldwide is the fuel used for cooking and heating. When these fuels are burned, the process can cause pollution inside the home, particularly if there is not good outdoor air exchange (ventilation). This fact sheet focuses on air pollution caused by burning fuels in the home. How does burning fuel cause pollution in the home? What lung problems can indoor pollution from Burning of fuels inside homes generates a complex mixture burning fuels cause? of indoor air pollutants. The key air pollutants include soot Household air pollution is harmful to people of all ages, and and other small particles (called particulate matter) that can may start having a harmful impact on lung function soon be breathed in and damage the lungs. Liquefied petroleum after birth or even before a baby is born. The most common gas, natural gas, ethanol, and electricity are considered clean lung problem from household air pollution in adults is chronic fuels, but not all clean fuels are equal. Some studies find that bronchitis, a type of chronic obstructive pulmonary disease cooking with gas stoves, particularly if they are unvented, (COPD). Regular exposure to indoor air pollution can increase may increase indoor levels of nitrogen dioxide, causing air the risk for asthma, tuberculosis, interstitial lung diseases, pollution. heart disease, and lung cancer. -
THE GUIDE to SOLID FUELS This Leaflet Will Tell You All You Need To
THE GUIDE TO SOLID FUELS This leaflet will tell you all you need to know about: • The different solid fuels available and their suitability for the various types of appliances • Smoke control legislation • Buying solid fuel • Hints on getting the best from your fuel and appliance Choice of Fuel There are a great many different solid fuels for sale. Your choice will be based on a number of criteria, the most important of which will be the type of appliance you will be burning the fuel on and whether or not you live in a smoke control area (see page 4). Fuels for open fires Housecoal The most traditional fuel for open fires is housecoal. It is available in various sizes e.g. Large Cobbles, Cobbles, Trebles and Doubles. The larger sizes are usually a little more expensive than Doubles size. Housecoal comes from mines in Britain and other parts of the world, most notably Columbia and Indonesia. The coal may be sold by the name of the colliery it comes from e.g. Daw Mill, the port of entry e.g. Merseyport or a merchant’s own brand name, e.g. Stirling. Coal merchants also frequently sell the coal by grade – 1, 2 and 3 or A, B and C; 1 and A being the best quality. Wood Wood and logs can be burnt on open fires. They should be well-seasoned and preferably have a low resin content. You should not use any wood that has any kind of coating on the surface e.g. varnish or paint, as harmful gases may be emitted on burning. -
