how long can it take a 10 ton coal fired boiler to cool
What Size Heat Pump Should I Use for an 1800 Square Foot Home
One BTU is the amount of energy it takes to raise a pound of water one degree. When the issue is an air conditioner or heater, the unit is measured in tons. Each ton of heating or cooling capacity is equal to 12,000 BTUs. So a 1-ton heat pump creates or absorbs 12,000 BTUs. A 2.5 ton unit handles 30,000 BTUs, since 12,000 times 2.5 equals 30,000.

Cooling tower - Wikipedia
A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely solely on air to cool the working fluid to near
