Kitchenaid 4-Burner Gas Grill With Searing Side Burner

By | September 10, 2022

Even the simplest gas grill is more than complex than a typical charcoal grill. Common components of a gas grill include:


  • Gas source

  • Hoses

  • Valve regulators

  • Burners

  • Starter

  • Cooking surface

  • Grill body

  • Grill hood

The
grill body
houses all of the other components except the hood. The
hood
covers the cooking surface and serves to trap the heated air inside, which increases the temperature inside the grill.

The
gas source
is connected to the
valve regulators
via the
main hose. The regulators are controlled by knobs that allow you to make up one’s mind how much gas is allowed through the valve to the burner. Well-nigh grills have two main burners, with a regulator for each one. Each burner has a series of tiny
holes
along its length that the gas exits through.

Iii things are required for a gas grill to
ignite
properly:


  • Gas

  • Oxygen

  • Spark

The
gas
is supplied from the propane tank or the natural-gas pipeline (more on this in the next department), and
oxygen
comes from the air. But where does the
spark
come up from?

The spark usually is supplied past the grill
starter, sometimes chosen the
igniter. This is a push-button or rotating knob that creates a spark of electricity to ignite the gas. The starter uses
piezoelectricity
to generate a nice spark that lights the grill.

The starter on this grill uses a knob that you turn to trip the hammer.

Sure crystalline materials (similar quartz, Rochelle common salt and some ceramics) have piezoelectric behavior. When you apply
pressure
to them, you lot go a
charge separation
within the crystal and a
voltage
across the crystal that is sometimes extremely loftier. For example, in a grill starter, the popping dissonance yous hear is a little spring-loaded hammer hitting a crystal and generating thousands of volts across the faces of the crystal.

Turning the knob on this grill causes the spark to jump between the two electrodes.

A voltage this high is identical to the voltage that drives a spark plug in a gasoline engine. The crystal’due south voltage generates a spark large plenty to light the gas in the grill.

Burners in gas grills often look like flattened "O"s riddled with small holes.

The
burner
is where all the actual burning occurs. It mixes the gas with oxygen and spreads it out over a large surface area to burn. Each burner has a pair of
electrodes
continued to the starter. When the starter’due south hammer is tripped, the resulting surge of electricity causes a spark to arc across these electrodes and ignite the gas/oxygen mixture. To create an evenly heated cooking surface, most gas grills have at to the lowest degree 2 separate burners.

Next, we’ll have a look at the fuels nigh ofttimes used in gas grills.
