What is a solar chimney / solar tower?
AVE - FAQA solar chimney (also known as a solar tower) is a solar thermal power plant wherein heated air rises in a tall chimney. The inflowing air is heated in a greenhouse with an open rim surrounding the base of the chimney and a turbine at the base of the chimney turns a generator to produce electrical power. Additional information on solar chimneys can be found on the AVE - Links page, "Solar Chimney" section.
Related QuestionsWhat is the Manzanares solar chimney?
AVE - FAQThe Manzanares solar chimney was a prototype built in Spain in the early 1980's. The experimental chimney was financed by the German and Spanish governments and operated successfully for 7 years. The chimney had a diameter of 10 m and a height of 200 m. The base of the chimney was surrounded by a 200 m diameter greenhouse with an open outer rim. The transparent plastic roof of the greenhouse was 2 m above the ground.
Related QuestionsWhat is the Enviromission solar tower?
AVE - FAQIn the early 2000's, the Australian company EnviroMission proposed building a 200 MW capacity solar chimney in Mildura south west Australia. The chimney was planned to have a height of 1 km and a diameter of 130 m. The solar collector would have a diameter of 7 km. The estimated cost of the Australian solar chimney is $800 million.
Related QuestionsWhat is Solar Tower Technology?
EnviroMission Ltd.Solar Tower technology is not simply solar energy. Solar Tower technology is created when the sun's radiation is used to heat a large body of air, which is then forced by the laws of physics (hot air rises) to move as a hot wind through large turbines to generate electricity. A solar thermal power station using Solar Tower technology will create the conditions to cause hot wind to flow continuously through its turbines to generate electricity.
Related QuestionsWhat are the advantages of the AVE (Atmospheric Vortex Engine) compared to a solar chimney?
AVE - FAQThe thermodynamic basis of the AVE (Atmospheric Vortex Engine) and the solar chimney is virtually identical. However, the AVE has some significant advantages A tall chimney is not required. The atmospheric vortex engine replaces the chimney with centrifugal force of a vortex to generate a "virtual" chimney. The construction of an extremely tall chimney (1 km as in the Enviromission proposal) is not required.
Related QuestionsWhat is the minimum surface temperature required for a solar chimney and for an AVE?
AVE - FAQThe temperature differential at the base of Manzanares solar chimney was typically 20?C. A solar chimney 5 times as high (1000 m high) would need a temperature differential of 4?C to produce the same power. The frictional losses in the Manzanares chimney were less than 10% of the ideal work and could be kept to the same level by a slight increase in chimney diameter. The temperature of sandy soil during periods of insolation can be 30?C higher than the temperature of the air at the 10 m level.
Related QuestionsWhy hasn't Solar Tower technology been developed before now?
EnviroMission Ltd.Formerly referred to as Solar Chimney technology in academic literature - it is now marketed without the reference to chimney (to avoid confusion with the pollution associated with chimneys - this technology is emission free) - the Solar Tower has had in excess of A$35 million and twenty years of research and development invested in it. Now, more than ever before, the time is ideal to apply this technology.
Related QuestionsWhat will a Solar Tower power station look like?
EnviroMission Ltd.View Image. The power station will be based on German designed Solar Tower technology. It will look like an enormous greenhouse canopy with a very tall hollow ventilation Tower located at its centre. The sun's radiation will be collected and trapped under the transparent canopy, creating a massive force of air heated to around 35?C greater than the ambient temperature.
Related QuestionsWhat is a cooling tower?
Distributed Energy Program: Frequently Asked QuestionsEvery type of air conditioning or refrigeration process is a means of moving heat from where it is not wanted to medium where it can be rejected. The radiator of a car is a dry, finned-tube heat exchanger that is used to reject engine heat to the outdoor air efficiently. A cooling tower is essentially a wet heat exchanger used to reject heat from a chiller or excess heat from a HRSG. The water spray over tube banks in a cooling tower is more efficient at rejecting heat than a dry heat exchanger.

FlueCleaner.com - FAQClose the damper on the appliance and/or the primary air inlet control. This limits the amount of air and helps reduce the fire's intensity. (If you have a barometric damper close this as well.) Open the doors to the appliance enough to get the nozzle of a 10lb. dry chemical fire extinguisher rated for ABC or ABCD type fires. Use the entire fire extinguisher inside your appliance and shut the door quickly.

Princeton Township - Bureau of Fire Prevention FAQWith the heating season, we have a tenacity to close ourselves inside our homes. While we mostly check our heating systems, the same care of our chimney(s) needs to be looked at as well. Sometimes chimney can become blocked by birds nest, bees, and other critters. They may only partial block the opening. Some times they do break, and or collapse. A good visual inspection of the Chimney should be conducted by qualified and reputable groups that do that kind of work.

What is the purpose of the chimney? Why does the chimney need to be so tall?
AVE - FAQThe purpose of the chimney structure is to prevent the warm buoyant air inside the chimney from mixing with the surrounding cooler ambient air outside the chimney via entrainment. Without the chimney, the warm rising air from the solar collector would quickly mix with the ambient air which would rapidly reduce its buoyancy. The maximum efficiency of a solar chimney is proportional to its height; the taller the chimney, the more work can be captured by the turbine.
Related QuestionsWhen should I have a chimney professional inspect my chimney?
HomeSaver Web SiteIf you are using the chimney to vent a fireplace, wood, coal or pellet stove or a gas or oil appliance, the flue should be inspected and cleaned, if needed, once a year.

Take a level and measure the roof pitch. It is the amount the roof drops per foot. Example. A 2' level shows a drop of 10". Divide by 2 for the length of the level equals a 5 on 12 roof pitch (or 5" drop to the foot). Now to figure the correct chimney height. ??? roof pitch times 10 plus 24 equals chimney height. Staying with the same 5 on 12 example.
