Cleaner Diesel Emmisions

Share Diesels fuels are now giving off cleaner emissions New Legislation The 2010 Emissions Regulations passed in by the EPA demand major reductions in the NOx and NMHC emissions produced by diesel engines. Under the new regulations, diesel engines manufactured after January 1, 2010, are required to emit less than 0.14 grams per brake horsepower hour (g/bhp-hr) of non-methane hydrocarbons (NMHC) and 0.2 g/bhp-hr of nitrogen oxide (NOx). To comply with the new NOx emission limits, most manufacturers of diesel trucks are using Selective Catalytic Reduction (SCR) systems. These systems reduce heat loads on engines and improve fuel efficiency while lowering NOx emissions. What is an SCR system? The SCR systems are fairly simple. They require the installation of a tank of diesel exhaust fluid (DEF)a mixture of 67.5% de-ionized water and 32.5% automotive grade urea plus wiring and sensors. SCR systems inject a vapor of DEF into the truck’s exhaust stream and the DEF then converts NOx emissions into water vapor. Roughly one gallon of Diesel Exhaust Fluid is needed for every 100 gallons of diesel fuel, so the DEF tanks dont have to be huge or add too much extra weight to trucks. The complete infrastructure for DEF distribution is still being developed, but its already available from pumps, in drums and in smaller pre-packaged containers at travel stops across the U.S. DEF safety and storage DEF is mildly corrosive but basically safe. OSHA regards DEF as mildly irritating to eyes and skin and recommends using soap and water on equipment or body parts that come in contact with it. Diesel Exhaust Fluid is clear and watery with a slight ammonia smell, and it needs to be stored at temperatures between70 and 11 degrees Fahrenheit. Impact of 2010 regulations The new EPA regulations have caused some operational impact and price increases, but the SCR systems also improve fuel efficiency by up to 7%. These savings on fuel, plus the systems light weights and ease of operation, make SCR systems cost effective in the long run. SCR systems automatically shut down when DEF levels fall below a certain level. This causes the engine to not start and could leave drivers stranded if they dont have a backup supply of DEF available. So far the distribution system has been adequate and this hasnt been a problem. Future of SCR systems and DEF No one likes the hassle and price increases that go with new environmental regulations, but the impact of the 2010 EPA regulations on NOx should be fairly minimal on the diesel industry. The SCR systems do an excellent job of reducing NOx emissions and their operating costs are more than canceled out by the increased fuel efficiency they provide. The durability and performance of SCR systems over time is unknown, but with their simple design and scarcity of moving parts the systems will likely provide reliable environmental benefits for years.

The Tube Solar Power Collectors: Key Aspects

We continue speaking about the tube solar power collectors. Due to the fact that the coolant flows directly through the pipe in the reservoirs they have, there are difficulties in the installation. Each tube should be connected to the system separately in order to avoid leakage of coolant. We need also serious maintenance, because leakage or mechanical damage even of one tube stops the work of collector. The vacuum tube consists of two glass tubes: outer is made from ultra strong transparent borosilicate glass that can withstand the impact of hailstones with a diameter of 25 mm, internal one is the same but with a special selective coating (A1-M/A1) that ensures excellent heat absorption with minimal reflection. In order to avoid conductive and convective heat loss from the space the air is exhausted between the two tubes. To maintain the vacuum barium gas absorber is used, which is exposed to high temperatures in a production environment, resulting in lower end of the vacuum tube is covered with a layer of pure barium. It absorbs CO, CO2, N2, O2, H2O and H2, which are distinguished from the tube during storage and operation, and is a clear visual indicator of the vacuum. When the vacuum disappears, barium layer transforms into white from silver. This makes it easy to determine whether a pipe works correctly. The absorption of heat occurs in the copper heat-pipe, which is located inside the vacuum tube. Method of heat transfer from its thermal conductivity is very simple. Copper tube is hollow and contains a patented inorganic non-toxic liquid. When heated, the liquid evaporates, and because of the vacuum created inside of a tube, it occurs even at a temperature of 25-30 ? C. The vapor rises to the tip (that is to say condenser) heat pipe, which gives off the heat to water, which flows through the thermal conductivity. Then it condenses and flows down, and the process repeats again. Solar collector with vacuum tubes shows excellent results on cloudy days, because the tube can absorb energy from infrared rays that pass through the clouds. With insulating properties of the vacuum influence of wind and low temperatures on their work is so insignificant in comparison to the impact on the flat solar collector. The system works successfully down to -35 ? C. Packed tubes are round, so that the amount of solar radiation reaching the collector remains fairly constant from mid morning until mid-day. This brings increasing in the total amount of absorbed solar radiation. The shape of pipes provides superior degree of absorption, since the sun’s rays always fall on its surface at a right angle, reducing the reflection to a minimum. Pipes are laid in parallel inside the collector. The angle of inclination depends on the latitude of the place. Having been oriented from north to south, they passively follow the sun during the day. This collector requires virtually no maintenance. Manufacturers offer the guarantee up to 25 years for similar products. The system is fully maintainable: if necessary, the pipe can be replaced, added or removed without stopping of the collector. Luckily we live in the times when the government start to realize the value of living in harmony with the nature on this planet. And solar power grants is a realistic proof of it. If you want to make a switch to solar energy, please read more about how solar power grants and how exactly you can use these solar power grants for your living. P.S. Good information makes life easier.
