Identify the steps in geothermal power plant by choosing the words from the word bank. ( i want to edit the pix, putting a rectangle per number) Chapter Summary Heat is a form of energy that comes from many different sources and is used to produced steam. The steam produced exerts pressure and expands in the cylinders of a steam engine or steam turbine. Then, the expansion of steam turbine is translated into work. Fuel oils like gasoline are vaporized in internal combustion engines and ignited automatically producing heat, which is then translated into work.
Small amounts of ozone develop naturally, especially during lightning storms, but spew industrial chemicals and automobile exhausts into the atmosphere, cook them with heat and sunlight, and ozone levels can rise dangerously high. Ozone is the main component of “photochemical smog”. Oxygen, a gas that we inhale with every breath, is essential to life on Earth. But as a chemical, oxygen is reactive. That property makes it life-sustaining and also a source of pollution.
This is usually a mixture of short and long chain hydrocarbons, aromatic hydrocarbons and some sulfur. The volatile matter content indicates the rank of coal and it is usually evolve in gaseous form during carbonization. It is known to decrease with increase in rank and is one of the most important parameter used in determining the suitability of coal for metallurgical utilization. Volatile matter, apart from its use in ranking, is one of the most important parameters used in determining other suitable application of coals (Peng, 2002). High-volatile bituminous coal due to its high volatile matter content generates high pressure during carbonization which is detrimental to the coke oven walls (Nasirudeen and Jauro, 2011).
These problems can be overcome by using hot metal from mini blast furnace (MBF) as iron bearing charge materials in EAF. The use hot metal offers the possibility of producing steel at lower costs than in traditional scrap based EAFs.11Use hot metal in EAF steel making has resulted in major cost saving, (including power) increased productivity and independence from steel scrap shortage and its price fluctuations. Recently, Jindal steel and power ltd. Raigarh is installing a BF of 351 m3volume for production of hot metal to be used in EAF for steel making. This furnace is rated to produce 0.238 Mt / year of hot metal / pig iron.
Introduction Energy Efficiency has become one of the important factors to consider in designing chemical processes due to the trending energy prices, limited fossil fuel resources and strict environmental regulations being applied worldwide. It has become important to increase processing energy efficiency in order to improve overall production economics of existing plants and new designs as well. (1),me. Heat integration and optimization is a reliable method for energy conservation and energy efficiency. It uses heat sources and sinks in the plant within the plant and utilizes it to the maximum thus reducing external cooling and heating with the relevant cost and emissions.
Like ride a motor bike, use air conditioner, industry rubbish, etc. Furthermore, air pollution can cause the global warming and green house effects in long day it’ll cause skin cancer and other kinds of cancer. Or at least abuse thermal energy too much. Image Source: http://www.nrdc.org/air/images/feature-main-air.jpg Not only the air pollution but it have many, many kinds of pollution that people has cause by using alternative energy in the wrong way. Like: Water pollution, thermal pollution, etc.
These enhance immunity in the seeds but eating them can decrease the effectiveness of actual antibiotics 3)CHEMICAL CONTAMINATION: Modified genes in the Biotech food may have human health risks because when genes are altered, some chemicals are used to get certain traits, like for example, to improve the resistance to powerful herbicides. Soybean are genetically engineered to resist herbicides which normally kills all the weeds and different plants in the discipline. As a result, the meals you eat will contain insecticides and herbicides that leads to ruining our health, visual imbalance and leads to most cancers. ECONOMIC
The operations of power reactors and nuclear fuel processing units constitutes the major contributor of heat in the aquatic environment. Coal fired power plants also constitute a major source of thermal pollution. The condenser coils in the plants are cooled with water which
DDT is slowly converted to DDE (dichlorodiphenyldichloroethylene)and DDD (dichlorodiphenyldichloroethane) by micro organisms and has a half life of two to 15 years. DDD and DDE are also toxic. Some DDT ends up in plants and then moves to the fatty tissues of birds, small animals and other animals that consume the plants or are otherwise exposed to low levels of DDT. DDT and it's derivatives are harmful to humans as well as animals. In humans, DDT affects the nervous system and can cause tremors and seizures.
When the water is toxicated, the toxins will move from the water to animals who drinks the water and when humans also eat the meat of these animals the toxic is transferred to them which is definitely going to cause damage. Spread of diseases through polluted water. Infectious diseases such as typhoid and cholera can be spread or contracted from drinking contaminated water. The human heart and kidneys can be badly affected by regularly consuming polluted water. Other health associated problems includes poor blood circulation, skin lesions, vomiting and damage to the nervous system.
