Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant’s steam-generating boiler, or other large combustion device. Flue gas is usually composed of carbon dioxide (CO2) and water vapor as well as nitrogen and excess oxygen remaining from the intake combustion air. It also contains a small percentage of pollutants such as particulate matter, carbon monoxide, nitrogen oxides and sulfur oxides. The flue gas stacks are often quite tall, up to 400 meters (1300 feet) or more, so as to disperse the exhaust pollutants over a greater area and thereby reduce the concentration of the pollutants to the levels required by governmental environmental policy and environmental regulation.When the flue gases are exhausted from stoves, ovens, fireplaces, or other small sources within residential abodes, restaurants, hotels, or other public buildings and small commercial enterprises, their flue gas stacks are referred to as chimneys.HistoryThe first industrial chimneys were built in the mid-17th century when it was first understood how they could improve the combustion of a furnace by increasing the draft (draught) of air into the combustion zone. As such, they played an important part in the development of reverberatory furnaces and a coal-based metallurgical industry, one of the key sectors of the early Industrial Revolution. Most 18th century industrial chimneys (now commonly referred to as flue gas stacks) were built into the walls of the furnace much like a domestic chimney. The first free-standing industrial chimneys were probably those erected at the end of the long condensing flues associated with smelting lead.The powerful association between industrial chimneys and the characteristic smoke-filled landscapes of the industrial revolution was due to the universal application of the steam engine for most manufacturing processes. The chimney is part of a steam-generating boiler, and its evolution is closely linked to increases in the power of the steam engine. The chimneys of Thomas Newcomen steam engine were incorporated into the walls of the engine house. The taller, free-standing industrial chimneys that appeared in the early 19th century were related to the changes in boiler design associated with James Watt “double-powered” engines, and they continued to grow in stature throughout the Victorian period. Decorative embellishments are a feature of many industrial chimneys from the 1860s, with over-sailing caps and patterned brickwork.The invention of fan-assisted forced draft (draught) in the early 20th century removed the industrial chimney’s original function, that of drawing air into the steam-generating boilers or other furnaces. With the replacement of the steam engine as a prime mover, first by diesel engines and then by electric motors, the early industrial chimneys began to disappear from the industrial landscape. Building materials changed from stone and brick to steel and later reinforced concrete, and the height of the industrial chimney was determined by the need to disperse combustion flue gases to comply with governmental air pollution control regulations.Flue gas stack draft (or draught)The stack effect in chimneys: the gauges represent absolute air pressure and the airflow is indicated with light grey arrows. The gauge dials move clockwise with increasing pressure.Main article: Stack effectThe combustion flue gases inside the flue gas stacks are much hotter than the ambient outside air and therefore less dense than the ambient air. That causes the bottom of the vertical column of hot flue gas to have a lower pressure than the pressure at the bottom of a corresponding column of outside air. That higher pressure outside the chimney is the driving force that moves the required combustion air into the combustion zone and also moves the flue gas up and out of the chimney. That movement or flow of combustion air and flue gas is called “natural draft (or draught)”, “natural ventilation”, “chimney effect”, or “stack effect”. The taller the stack, the more draft (or draught) is created.The equation below provides an approximation of the pressure difference, ?P, (between the bottom and the top of the flue gas stack) that is created by the draft:where:?P= available pressure difference, in PaC…(and so on) To get More information , you can visit some products about leg foot massager, firefighting equipment, .

Can I Run a Diesel Engine on any Engine Dynamometer?

TAGS: None

I’m doing a research project on how biodiesel levels in fuel affect horsepower and fuel efficiency, and I’m having a lot of trouble setting up a test. First, I don’t know if i should use an engine dynamometer or a chassis dynamometer. Second, I’m having trouble getting a car/bike/engine to run tests with. Any advice?

Stirling Cycle Engine from Tin cans

I designed the engine to see how simple one could be made from easily avaiable items. A lathe is not essential can be made with hand tools and drill.

5.9 is the rated 0-60 on the 2005 300C, so we were pleased when we got six flat on the almost four year old car. The 300C: The 300C comes with a 5.7 L Hemi V8. At full power, the 300C creates 340 hp and 390 lbs of torque. This engine runs on four cylinders when less power is needed to reduce fuel consumption. Even with this energy saving mode, the 300C runs at 15 mpg city, 23 mpg highway. All 300Cs use a 5-speed automatic transmission and standard 18 inch chrome-clad alloy wheels. Heritage Edition: The Heritage Edition 300C comes with the 5.7 L Hemi engine and many of the SRT-8′s exterior modification, added chrome, special tires on 18 inch wheels, and smartbeam headlights. Special SRT Packages: In 2007 the SRT Design group created a package for non-SRT 300C’s that includes performance suspension, SRT 20 inch polished aluminum wheels, a high speed engine controller with revised tuning for 5.7 L HEMI that brings the power to 350 HP, high flow air cleaner system, and performance exhaust. The SRT-8: The SRT-8 version of the 300 includes a 6.1 L Hemi V8 which produces 425 hp. This engine produces 0-60 mph times of 5.1 seconds. The SRT-8 includes leather SRT-8 performance seats, 20 inch polished aluminum wheels, Brembo brakes, and rear lip spoiler.

Any ideas for crafts to make out of old auto parts?

Crate Engine?

Tags:

I am looking on crate engines for my classic car. I have a 1967 Chevy Impala 4 door that currently has a 283 engine. The engine is currently working well but I eventually would want to have a crate engine installed when my current engine gives up. I am looking for a mix of performance and efficiency. My friend told me to get a 350 small block V8 because he swears that is Chevy’s best engine ever made but I would want to have other opinions. I still want to use 87 octane so nothing to powerful.

If any of you have websites for engines please paste them in your answer as well so I can take a look.
