Jet dryers are used to dry out racetracks, with some capable of drying asphalt in as little as 90 minutes. They were introduced to NASCAR in 1976 by team owner Roger Penske. Jet dryers can use a significant amount of fuel, with some models burning 200 gallons of jet fuel per hour. Newer models, such as Tim's Akron Turbine Group's jet dryer, use a more efficient 30 gallons of kerosene. Other factors that influence fuel consumption in jet dryers include engine type, technology, and the duration of usage.

Jet dryer fuel type
Jet dryers are used to dry racetracks and asphalt construction sites. They are a combination of trucks, airplanes, and hot-air blowers. They were introduced to NASCAR in 1976 by team owner Roger Penske. Jet dryers use a 1950s jet engine to produce air at temperatures of about 1100 degrees Fahrenheit, drying the racing surface in as little time as 90 minutes.
The fuel type used by jet dryers is a variation of kerosene jet fuel. The fuel tank is self-contained, and the dryer can be operated by a single person from inside the truck. The jet dryers used at NASCAR can hold 200 gallons of fuel, which is burned in an hour. However, newer jet dryer designs carry a much smaller amount of fuel, with 30 gallons of kerosene replacing 200 gallons of fuel.
The use of kerosene instead of gas increases safety. The jet dryers are loud, and their exhaust can damage the racetrack due to the high temperatures produced. During a race in 2007, the crews at MIS burned an estimated 12,000 to 15,000 gallons of jet fuel to dry the track.
The amount of fuel burned by jet dryers can be compared to that of private jets. Private jets typically use between 50 and 500 gallons of fuel per hour, depending on their size and model. Smaller jets generally use about 100-200 gallons per hour, while larger jets can consume 300-500 gallons per hour. Light jets, suitable for short trips, consume approximately 120 to 260 gallons of fuel per hour. Midsize jets, used for medium-haul flights, use 220 to 350 gallons of fuel per hour. Heavy jets, designed for long-haul flights, have a fuel consumption ranging from 340 to 500 gallons per hour.

Akron Turbine Group’s Jet Dryers
Akron Turbine Group's jet dryers, designed by Tim, are known for their use in the asphalt and construction industries, as well as at dragstrips and speedways. These jet dryers can be powered by kerosene instead of gas, with Tim's newest design carrying 30 gallons of kerosene compared to the previous 200 gallons of fuel. These dryers can be permanently installed or quickly mounted and removed, allowing for versatility in their use.
NASCAR's Jet Dryers
NASCAR's jet dryers, powered by jet engines, consume a significant amount of fuel. The Westinghouse J34 jet engine, for example, can hold and burn 200 gallons of jet fuel per hour. This high fuel consumption is a trade-off for the efficiency and speed that jet dryers provide in drying surfaces or clearing debris.
Fighter Jet Fuel Consumption
Fighter jets, such as the F-16 Fighting Falcon, can consume approximately 3,800 liters of fuel per hour during high-altitude routine missions. The F-22 Raptor, a more advanced aircraft, can exceed 8,000 liters per hour due to its vectored thrust and stealth technology. Weight is also a critical factor, as extra fuel and weapons increase fuel consumption. Additionally, combat and training missions with frequent speed and altitude changes can result in up to 30% more fuel consumption compared to straight-line flights.
Commercial Jet Aircraft Fuel Consumption
Commercial jet aircraft fuel consumption varies depending on various factors, including aircraft type, size, empty weight, payload, engine efficiency, flight path, and weather conditions. For example, the Airbus A350 consumes 38 pounds of fuel per nautical mile, while the Boeing 747 burns up to one gallon of fuel every second during a five-hour flight, amounting to 18,000 gallons. The Airbus A380, the largest passenger aircraft, consumes approximately 4,600 gallons per hour, resulting in 23,000 gallons for a five-hour flight.

Jet dryer tank size
The jet dryer tank size varies depending on the model and purpose of the jet dryer. For example, jet dryers used for NASCAR races have a fuel tank capacity of 200 gallons of jet fuel, which is burned in an hour. The jet engine used in these dryers is from the 1950s and can generate air temperatures of up to 1100 degrees Fahrenheit, effectively drying the racetrack in 90 minutes if the rain stops.
Akron Turbine Group's jet dryers, designed by Tim, also have a fuel tank capacity of 200 gallons. However, Tim has designed his dryers to run on kerosene instead of gas, with a newer model carrying only 30 gallons of kerosene. These dryers are used at dragstrips and speedways and can be permanently installed or quickly mounted and removed, providing versatility for users.
Jet dryers are a combination of trucks, airplanes, and hot-air blowers, and their large size and loud noise distinguish them from race cars. They are essential for ensuring the safety of races, as a wet track can cause race cars to slide sideways on steeply banked turns. While effective in drying tracks, jet dryers have been criticised for their environmental impact, with one race estimated to have burned 12,000 to 15,000 gallons of jet fuel.

Jet dryer safety considerations
Firstly, jet dryers should be operated with strict adherence to safety protocols. The operators should be well-trained and equipped with the knowledge to handle the machinery safely. This includes understanding the fuel system, which in some designs is kept simple to aid operator focus on the task at hand. Additionally, jet dryers should have safety features like high-speed, high-temperature, and low oil pressure warnings to alert operators of potential hazards.
Secondly, the choice of fuel is an important consideration. Some jet dryers, such as those designed by Tim from the Akron Turbine Group, use kerosene instead of gas, as it is considered a safer option. Kerosene has a lower risk of ignition due to its higher flash point compared to other fuels. This reduces the chances of accidental fires or explosions.
Thirdly, the powerful jet engines used in these dryers can generate extremely high temperatures, reaching approximately 1100 degrees Fahrenheit. This heat is directed at the surface to be dried, which can cause thermal stress and damage if not carefully managed. For example, when used on asphalt racetracks, the extreme heat can cause the asphalt to expand and crack due to the uneven heating of its composite materials. Therefore, operators must be cautious and informed about the potential impact of the dryers on different surfaces.
Furthermore, jet dryers should be properly maintained and regularly serviced to ensure all components are in good working order. This includes the engine, fuel system, and any safety features. Proper maintenance reduces the risk of malfunctions that could lead to unsafe conditions.
Lastly, jet dryers should be used in well-ventilated areas to mitigate the risks associated with the combustion process. The dryers emit exhaust gases, and in enclosed spaces, these gases can accumulate, posing health and safety hazards. Therefore, it is crucial to operate them in open areas or ensure adequate ventilation in enclosed spaces.
In conclusion, jet dryer safety considerations encompass various aspects, including operator training, fuel choice, surface impact, machine maintenance, and ventilation. By prioritizing these factors, the risks associated with jet dryer operation can be effectively managed, ensuring a safer experience for all involved.
