The finishing industry plays a vital role in the processes of other industries. Businesses that utilize the services of the finishing industry are those that need to strip off powder coatings and paint from metal fixtures and hardware. Finishing experts should follow industry safety standards to ensure that the products are processed without harming anyone. One of the ways to ensure quality and safety in the finishing industry is by using industrial burn off ovens.
What is a Burn Off Oven?
The purpose of a burn off oven is to strip off powder coating, paint, and other dry combustible material from fixtures, hooks, racks, hangers, brake shoes, and more. A burn off oven is a heavy-duty piece of equipment that incinerates and chemically decomposes combustible organic materials. The process works by applying heat just enough to burn off the organic material without causing any damage to the fixtures or hardware. Flammable materials that can be chemically removed by industrial burn off ovens aside from paint and powder coating are adhesive, epoxy, fiber, grease, lacquer, plastic, urethane, and varnish,
Industrial burn off ovens has water suppression systems that release water mists to kill any fire or flare-ups during the process. These ovens are designed to be operated in a vacuum condition further to reduce any chances of flare-ups in the materials. The following also explains a burn off oven’s working mechanism:
- The parts that will be stripped off of their coatings are placed inside the oven
- The burn off oven is turned on, and the combustible materials begin to fall off as the temperature rises to 800°F
- The coating turns into fumes and ash; the latter becomes inorganic pigmentation
- The fumes, on the other hand, passes through the afterburner chamber, whose temperature turns up to 1400°F for a very short time
- The coating is removed successfully from the material’s surface
Industrial burn off ovens are not only environment-friendly; they are safe to use with the right training and proper gear.
Is It Safe to Use an Industrial Burn Off Oven?
Naturally, there will be concerns over the safety of gas-fired and high-pressure equipment. The possibility of things going wrong is endless. However, the design of industrial burn off ovens is made to work under very high temperatures. Just like any incinerator, the fire is contained safely. The built-in water spray systems immediately douse potential flames. Industrial-standard burn off ovens is equipped with open-top explosion relief doors to push out the excess pressure yet prevent any air from coming into the oven.
A safe and high quality burn off oven will not damage any of the parts placed in. The fire is contained inside a combustion chamber, so only the heat touches the parts and not the flame. Industrial burn off ovens are safe because air cannot enter the equipment, thus, preventing any unwanted combustions that might cause a fire, or worse, an explosion.
Ensuring Safety When Using a Burn Off Oven
An industrial-grade burn off oven is a piece of fairly safe equipment that is essential for different industries. However, just like any equipment, a burn off oven can be hazardous if not used or maintained correctly. Here are some ways to keep a burn off oven safer to use:
- Keep the equipment in good working condition: No matter how safe a piece of industrial equipment is when you buy it, it will likely need maintenance or repair to keep it in good shape. Neglecting to replace defective or broken parts will result in a piece of hazardous equipment. Contact the manufacturer to schedule upkeeps and necessary repair.
- Inspect the burn off oven regularly: Regular inspection will keep the burn off oven working efficiently. Before operating the oven, the water sprays should be checked to ensure that it produces the right amount of mist. It is also crucial to inspect if the combustion chamber provides the right amount of heat.
- Proper location: The burn off oven should be placed in an area with sufficient space for loading and maintenance. It should be placed in an area with adequate make-up air to prevent the oven from malfunctioning. Also, make sure that you obtain an operating permit before purchasing and installing a burn off oven in your facility.
Industrial burn off ovens are essential machines for different types of industries. Removing and cleaning combustible materials is a very time- and energy-consuming process. There are no contaminants released in the surroundings because the fumes and smoke produced is contained in the built-in afterburner and treated afterward. Many businesses utilize burn off ovens because they only require a few people to operate, are cost-efficient, and safe.
