need to compare an infared 1750 watt b.b.q.grill to a btu gas grill
Charmglow sells products that are useful and necessary for outdoor grilling, such as gas grills and gas grill parts. One example of a product that Charmglow sells is the 48,000 BTU Porcelain Series 4 Burner Grill.
What you are asking isn't really translatable. What do you want to reach 300F? Air requires 75 btu per pound to reach 300F. Water needs to be enclosed in a pressure vessel and needs roughly 1180 btu/lb. Propane itself burns at 3360F under perfect conditions. If you are referring to cooking grills any grill will cook food to 300F or higher, the lower the btu rating the longer the grill takes to cook the food OR the less food it can cook at a time. The bigger the grill the more food you can cook faster. An 18,000 btu grill should be plenty to cook food for 4 people, a 35,000 btu grill is better for 6-8 people, for parties or catering you may want to invest in a much larger grill , sizes can vary greatly. The btu rating on a grill refers to the amount of heat converted from the propane at full flame in one hour. (fats dripping from food and combusting also adds heat to a grill, the rating refers only to the propane)
A good gas grill is made by Weber, I would buy a smaller grill.
Many people prefer a charcoal grill over a gas grill. It is truly a matter of personal preference. I personally find that I like the gas grill because it is easier to light as well as maintaining a good cooking temperature. There is nothing specifically that states that one is better than the other though; it is really your preference.
They come in different sizes.
btu of natural gas to btu of propane
Natural gas has a heating value of about 1,000 BTU/ft3 (gross) or about 900 BTU/ft3 (net). Acttual values can range about 100 BTU/ft3 higher or lower than the average. So 1,750x106 BTU would be about 2,000 ft3
The average is about 20,000 BTU's per pound at standard temperature and pressure.
Natural gas typically contains about 1,000 BTUs per cubic foot. The specific BTU content of natural gas can vary depending on the source.
One MM BTU of natural gas weighs approximately 0.0284 kilograms.
102,000 BTU = 1 ccf
