Lithotripsy is a procedure that uses shock waves to break up stones in the kidney, bladder, or ureter (tube that carries urine from your kidneys to your bladder). After the procedure, the tiny pieces of stones pass out of your body in your urine.
Propane gas is ideal for grills because, when pressurized, it compresses and turns to liquid, making it easy to store in tanks. It also contains more cooking energy than natural gas as measured in British Thermal Units (BTU). A BTU is the amount of energy required to raise the temperature of one pound of water 1Â°F. There are about 2,500 BTU in one cubic foot of propane and only about 1,000 BTU in one cubic foot of natural gas. Manufacturers tout the number of BTU their grills can produce, but the number can be very misleading. BTU is not indicative of the heat it can generate.
If you are considering charcoal, think 9,000 BTUs per pound and pellets about 8,500. A 30,000 BTU gas grill emits 30,000 BTUs in one hour, or about two pounds of propane an hour. BTU's do not indicate how quickly a grill will heat up, but can indicate how much fuel you will be using while you cook.f you are considering charcoal, think 9,000 BTUs per pound and pellets about 8,500.
