Can cooling tower catch fire?
Can cooling tower catch fire?
A significant percentage of fires in cooling towers of combustible construction are caused by ignition from outside sources, such as incinerators, smoke stacks, or exposure fires. Fires in cooling towers also may create an exposure hazard to adjacent structures, buildings, and other cooling towers.
What is fire protection and detection system?
What is a Fire Detection System? Fire detection systems serve a simple purpose to spot fires early enough to allow for safe evacuation of personnel and, if possible, for a quick response to put the fire out. With the right fire detection system, the human and equipment costs due to damage can be significantly reduced.
What is the main working principle in cooling towers?
Cooling tower systems work by using water to extract waste heat from a system and ejecting it into the atmosphere primarily through evaporation.
What are the two types of cooling towers?
There are three main types of cooling towers that are defined by how water or air pass through them. These types include crossflow, counterflow, and hyperbolic. There are also two varieties classified solely on airflow, known as induced draft and passive draft cooling towers.
Why do cooling towers catch fire?
Cooling tower systems are widely considered to be inherently safe from fire hazards because water flows through them. But in fact, cooling towers are vulnerable to fire, as they contain dry areas, electrical equipment and one or more combustible materials such as PVC, fiberglass-reinforced plastic and ABS.
Which sensor is used in fire alarm?
Photoelectric sensors are the least costly and are employed widely in residential and other fire alarms. They comprise a light source, typically an IR LED and a photodetector, usually a photodiode, together with simple signal processing electronics (Figure 1), housed in a plastic enclosure.
What is wet bulb temperature in cooling tower?
Most cooling towers are capacity rated at a “standard” wet bulb temperature of 78°F.
What is condenser water?
A water-cooled condenser is a heat exchanger that removes heat from refrigerant vapor and transfers it to the water running through it. Having the refrigerant vapor condensed on the outside of a tube does this. In doing so, the vapor condenses and gives up heat to the water running inside the tube.
What is TR capacity in cooling towers?
A ton of refrigeration (TR) is a unit of heat extraction capacity of the refrigeration or cooling equipment. Generally, TR is defined as the amount of heat transferred to freeze or melt 1 short ton of ice at 0 deg. C in 24 hours. 1 TR is approximately equal to 12000 BTU or 3024 Kcal/hr of energy/heat load.
What is the meaning of TR in cooling tower?
A ton of refrigeration (TR or TOR), also called a refrigeration ton (RT), is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment.
What gas is commonly released by the cooling tower?
A common misconception is that they release pollution. In fact, what they actually release is water vapour – similar to, but nowhere near as hot, as the steam coming out of your kettle every morning.
