In addition, New York State contractors must install a carbon monoxide detector when replacing a fuel-burning water heater or furnace if the home is without an alarm. The law is named for Amanda Hansen, a teenager who died from carbon monoxide poisoning from a defective boiler while at a sleepover at a friend's house.
The gas fueling the furnace was shut off, but the raffinate feed into the splitter tower was not. The operators believed the level transmitter reading which was now down to 78% (7.9 feet [2.4 m]) but the fluid level in the 170-foot (52 m) tall splitter tower had now reached 158 feet (48 m). [53]
Wait (if furnace is relatively recent) until the heat exchanger is at proper operating temperature before starting main blower fan or circulator pump; Oil Similar to gas, except rather than opening a valve, the furnace will start an oil pump to inject oil into the burner Electric
In the night hours before the incident, the TMI-2 reactor was running at 97% power while the companion TMI-1 reactor was shut down for refueling. [22] The main chain of events leading to the partial core meltdown on Wednesday, March 28, 1979, began at 4:00:36 a.m. EST in TMI-2's secondary loop, one of the three main water/steam loops in a ...
Intermittent-use: There is a short delay (1–3 seconds) between when the water begins to flow and when the heater's flow detector activates the heating elements or gas burner. In the case of continuous-use applications (showers, baths, washing machines) this is not an issue as the heater never stops heating.
Carrie Furnace is a retired blast furnace located along the Monongahela River in the Pittsburgh area industrial town of Swissvale, Pennsylvania. It was one of the structures comprising the Homestead Steel Works .
It typically consists of a hot water pipe running behind a fireplace or stove (rather than hot water storage), and has no facility to limit the heating. Modern wetbacks may run the pipe in a more sophisticated design to assist heat-exchange. These designs are being forced out by government efficiency regulations that do not count the energy ...
Shutdown is the state of a nuclear reactor when the fission reaction is slowed significantly or halted completely. Different nuclear reactor designs have different definitions for what "shutdown" means, but it typically means that the reactor is not producing a measurable amount of electricity or heat and is in a stable condition with very low reactivity.
