Outdoor barbecue is a popular cooking method.In fact, about 75% of the population in the United StatesS.The family has Grill.The grill consists of a cooking surface, usually made of parallel metal strips or porcelainThe covered metal mesh, on a fuel source capable of producing high temperatures, is usually as high as 500 degrees Fahrenheit (260 degrees Celsius) or higher.There are several different types of grill, but gas and charcoal are the most common.In this article, you will learn about the various parts of the grill and how they work together.You will understand what charcoal is and how it is made, and the difference between liquidsPropane (LP) and natural-gas grills.You will find fewer others.Common types of grills and their sources of fuel.Let's start by taking apart the trusted charcoal grill.The components of the grill can range from very simple to very complex.The simplest Grill is a charcoal burner consisting of three parts: a common version of this arrangement uses a shallow circular container mounted on a metal tripod, with a circular cooking grill placed on top of the container.Take a look at the following example: the charcoal grill may be more complicated than this-Some people have a lid to cover the grill and the extra layered cooking surface-But it's basically the same.The source of fuel for the charcoal grill has been in existence for at least 5,000 years.No one is sure who discovered charcoal, or even which civilization used charcoal first.Evidence of charcoal has been found around the world.It was even used during the embalization of Egyptian mummies!You may not realize it, but charcoal is not a rock, not even some kind of coal.It's wood!Charcoal is produced by heating the wood to high temperatures without oxygen.That is, you put the wood in a sealed box made of steel or clay, heated to about 1000 F (538 C ).Why would you go through such a tedious process instead of just burning wood like it is now?The freshly cut wood contains a lot of water.-Sometimes more than half of its weight is water.Seasoned Wood (Wood allowed to be placed for a year or two) or kiln-Dry wood contains much less water, but still contains some water.The watery Wood cannot be cooked very effectively.In addition, when the tree is still alive, it contains sap and a variety of volatile hydrocarbons in its cells."Volatile" means that these compounds evaporate when heated.When you put a piece of fresh wood or paper on the heat, the smoke you see is those volatile hydrocarbons that evaporate from the wood.They start to evaporate at a temperature of about 300 F (149 C.If the temperature is high enough, the compounds will burn.Once they start to burn, there will be no smoke because the hydrocarbons will become carbon dioxide and water vapor (both are invisible ).This explains why you can't see the smoke from a charcoal fire (or a fire that has burned into ashes.This process removes all volatile organic compounds, leaving pure carbon and Ash (non-Combustible minerals in tree cells ).When you light charcoal, you burn pure carbon.It combines with oxygen to produce carbon dioxide, leaving ashes at the end of the fire-the minerals.This creates a very strong heat, with little smoke, making charcoal very useful as a cooking fuel and not flooding the taste of the food with elements from ordinary wood smoke.Barbecue lovers are passionate about the advantages of charcoal and gas barbecues, especially the difference in taste.Charcoal does offer a unique flavor that is not easy to replicate.This is a tough decision for many: the convenience of the gas grill is the opposite of the smell of charcoal.Let's take a look at the gas grills and how they work.
