The combustion chamber of the Velox could produce flue gasses by burning fuel gasses or heavy fuel oil. Blast furnace gas was typically used as fuel by Velox sets installed in steel mills. Efficiency of Velox steam generators was generally around 88—90% when burning blast furnace gas and 91—93% per cent with fuel oil.
Oil fumes, natural gas, propane, coal, or any other fuel can build up inside the combustion chamber. This is especially of concern when the vessel is hot; the fuels will rapidly volatilize due to the temperature. Once the lower explosive limit (LEL) is reached, any source of ignition will cause an explosion of the vapors.
The combustion chamber (A) is filled intermittently with an air–fuel mixture supplied by the gas chamber (C) and the air chamber (B). The air–fuel mixture is ignited by a spark after which the explosion of the mixture causes an increase in pressure throwing open the nozzle valve (F), allowing the compressed gases to flow through the nozzle ...
This is the largest oil spill of its kind (spill from an oil tanker) in history. January 8, 1979: Betelgeuse incident, a French constructed oil tanker which entered Bantry Bay, Ireland, exploded and killed 50 people, the disaster also caused extensive harbor damage. March 28, 1979: Three Mile Island accident. Partial nuclear meltdown.
Implosion is the collapse of an object into itself from a pressure differential or gravitational force. The opposite of explosion (which expands the volume), implosion reduces the volume occupied and concentrates matter and energy. Implosion involves a difference between internal (lower) and external (higher) pressure, or inward and outward ...
The roof then collapsed, severing fuel pipes and causing at least 100 people to fall four stories to the factory floor. 60 to 100 more people fell directly on top of a furnace, the surface temperature of which was estimated to be around 500 °F (260 °C). 23 people were killed, and over 100 more were injured.
The Oklahoma City bombing was a domestic terrorist truck bombing of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, United States, on April 19, 1995, the second anniversary of the end to the Waco siege. The bombing remains the deadliest act of domestic terrorism in U.S. history.
The Texaco Farms located on Doremus Avenue is an expanse of land on which a number of fuel oil storage tanks are located. Newark held roughly 40 tank farms, each holding about 3,142 million US gallons (1.189 × 10 10 L; 2.616 × 10 9 imp gal) of fuel.
