What is an Enclosed Ground Flare?

An Enclosed Ground Flare, also known as a thermal oxidizer or vapor combustor, is a combustion system that takes exhaust gases which are potentially toxic or flammable and converts them into less harmful vapors without using a stack.

There are two main types of ground flares, enclosed ground flares and open ground flares. The advantage of having an enclosed ground flare is that it does not require supports or a stack, like an elevated flare would. The removal of the stack portion of the system allows pilots and other weather sensitive equipment, which has a tendency to corrode, to be easily replaced and cleaned.

An enclosed ground flare is much more common than an open ground flare. This combustion system utilizes a refractory shell to enclose the incineration process. This essential shell shields radiation, the internal blaze and noise. The internal processes of the enclosed ground flare are the same as that of the elevated flare.

While an enclosed ground flare has a higher price tag, they are less expensive to operate and are easier to maintain. The handling capacity of an enclosed flare is between 50,000 and 250,000 lb/h and most units are smokeless.
An open ground flare can come in several different configurations. Most systems have multiple burners working together ignite large amounts of gas. Open ground flares are able to burn larger quantities at a time. These units are almost completely smokeless and have a very high gaseous conversion rate.
The open ground flare units contain a limited amount of space for the burners. This means that the units must be kept at a distance for safety reasons. These systems also require a gas pressure of 3-5 psi, which is much higher than any other type of flare system. While open ground flare units are effective, their bright light, noise and heat emissions require that the unit be used in a more secluded area.

Enclosed Ground Flares emit less noise, light and heat.

10 Things to Consider in an Enclosed Ground Flare

There are many different types of Enclosed Ground Flare Systems currently on the market. However, all of these units are not created equal. Here is a list of things to consider if you are in the market to buy an Enclosed Ground Flare.

  • Will the Enclosed Ground Flare unit meet BACT (Best Available Control Technology) criteria for destroying Hydrocarbons including Methane? BACT is a pollution control standard that equipment operators are required to meet based on energy consumption, emissions and environmental impact based on their location.
  • Are destruction efficiencies guaranteed? When paying for any Enclosed Ground Flare, you should always discuss the efficiency of the unit including CO emissions.
  • What is the Burner Turndowns ratio? The turndown ratio compares the max to minimum amount of heat that is put out. You want to make sure that your burner turndown ration is not too limited.
  • Does the Enclosed Ground Flare unit light and adjust automatically to the fuel and ratios or does this need to be done manually? Time is money so the more that can be done automatically, the better.
  • What will the upkeep cost you? Some Enclosed Ground Flare systems require expensive replacement matrixes. Make sure you ask about these maintenance costs with the manufacturer and factor them into your budget.
  • What is the construction material? The most durable material is heavy rolled steel. The manufacturer’s materials will determine the quality and lifetime value.
  • Will the Enclosed Ground Flare unit be trailer mounted or skid mounted?
  • What kind of control system and interface does the Enclosed Ground Flare unit come with? Are these components going to be UL classified?
  • Will the manufacturer assist you in acquiring the necessary permits? Determining what permits you need and applying for them is not an easy process so having help with this will save you time and money.
  • Will you be provided with drawings, an operating manual, and installation for the Enclosed Ground Flare system? Are these items included in the purchase price?

Our Most Interesting Customers and Their Industrial Oven

While we cannot disclose all of our Customer’s names, we can say that some of our customers make some fascinating and amazing products with their industrial oven. Our heat treat ovens, curing ovens, crucible furnaces, and other industrial oven systems are used for a variety of uses.  In fact, many of the products you use every day may have been treated in one of our ovens. If you aren’t sure what an industrial oven can do, check out some of our customer’s cool products that have been made using a Baker Furnace industrial oven.

One of our most intriguing ovens was used for a customer in the contamination protection business. This company uses several Baker Furnace gas-fired and electrically heated industrial ovens during their curing process. Our ovens are used in a unique drying stage required to create specialized safety gloves and other protective gear for PPE  (Personal Protective Equipment). The most common PPE known to the general public is the hazmat suit and now the Ebola protective suit. These specialty gloves are used to protect against asbestos, lead dust, radioactive contaminants, and other health-threatening substances. These products are composed of uniquely designed plastics and rubber that are impervious to gases, vapors, oils, and can withstand extreme temperatures from 160°-260°F.

Another customer of ours is a world leader in supplying first tier metallic and composite materials to the aerospace industry. To accomplish this, they use a Baker Furnace electric clean room batch industrial oven. This custom made industrial oven is used to manufacture segments of airplanes, helicopters and fighter jets. They also manufacture flexible protection systems, such as flexible fuel tanks that won’t explode during a crash, emergency flotation devices for helicopters, and portable fuel containers.

What kinds of interesting products do you manufacture?  We would love to talk with you about your processes and learn more about your heat treating needs. To receive more information about a Baker Furnace industrial oven system that is right for your unique requirements, contact our office at 1-800-237-5675. You can also click Here to contact our office to see what we can do for your business!
