colleges with water polo How Many BTU do You Need
British Thermal Unit (BTU) is the traditional unit of energy. The heat value of fuels and the heating power of gas grills can be expressed in terms of BTU. It is defined as the amount of heat energy needed to raise the temperature of one pound of water by one degree Fahrenheit at a constant pressure of 1 atmosphere. The BTU enebles us to compare the heat content of different types of fuel.
Whenever you shop for a gas grill and come across its BTU rating, be curious enough to understand which BTU the manufacturer is talking about. Find out if the BTU rating is for the primary burners or all the burners combined. those burners directly under the main cooking grate where you grill). If you add the BTU rating of all the primary burners and divide it by the area of the main cooking grate you get the BTU per square inch of main cooking area. For instance, if the primary burners of a gas grill have a BTU rating of 35,000 and the area of the main cooking grate is 500 inches, the grill will then have 35,000/500 = 70 BTU per square inch of main cooking area.
How many BTU do you need? In the past, we been advised to look for grills with about 100 BTU per square inch of main cooking area. This rule no longer applies because modern gas grills are now becoming more and more efficient at trapping heat. One thing you should know is that the temperature a gas grill can attain is not influence by the BTU rating alone. Another thing you should know is that a high BTU rating does not necessarily mean high temperature output. One major factor that influences the temperature your grill can reach is the ability of the grill to retain the heat. Grills that are constructed from lightweight materials cannot hold the generated heat and so will require a higher BTU rating for them to attain a high enough temperature for grilling or searing. Good grills that can reach high maximum temperature are made with heavy materials (heavy cooking grates) and their lid will close tight. Due to improved efficiency, some modern gas grills can reach high temperature with a BTU rating as low as 80 BTU per square inch of main cooking area.
Gas grills with low BTU rating burn less fuel than those with higher BTU rating. For example let calculate how much propane the primary gas burners will consume per hour. Propane has a BTU rating of know that propane has a BTU rating of} 15,000 BTUs per pound. Assuming that the primary burners of a gas grill are rated at 30,
000 BTU, the formula for calculating the amount of fuel they consume per hour can be gotten by dividing the BTU rating of the primary burners by that of propane. Doing this will give us 2 pounds per hour. Similarly, a 45,000 BTU primary burners will consume 3 pounds of propane per hour. Therefore, the higher the BTU rating of a gas grill the more fuel it will consume. But note that this calculation is made with the assumption that all the primary burners are set to their maximum output (you turn the control knob all the way up).
In order to achieve the very high temperature that can searing steak, some gas grills come with an additional cooking surface called the sear region. The sear region is where you can quickly sear your food before transfering them to the main cooking area to finish off the cooking.
Finally, prick up your sense of curiosity whenever you come across a grill with a very high BTU per square inch of main cooking area (somewhere above 150). This is often an indication of a poorly constructed grill that cannot retain heat and they will consume a lot of fuel.
