DETAILED DESCRIPTION OF THE INVENTION

Before describing the disclosed embodiments of this technology in detail, it is to be understood that the technology is not limited in its application to the details of the particular arrangement shown here since the technology described is capable of other embodiments. In addition, the terminology used herein is for the purpose of description and not of limitation.
In various exemplary embodiments, the technology described herein provides an improved, low-cost enclosed combustor to destruct vapors that are harmful to the environment such as hydrocarbons. Additionally, the technology described herein provides an interchangeable, modular panel structure for the enclosed combustor and to a burner manifold and nozzles to regulate the ratio of air and gas to achieve stoichiometric combustion.
Known manufacturers of enclosed combustion devices include Flare Industries, ABUTEC, Zeeco, and Cimarron Energy. There are numerous deficiencies and shortcomings in these known devices, systems, and methods that are utilized to reduce emissions such as hydrocarbons. By way of example, these devices cannot change capacity, and require heavy equipment and specialized teams to install and start them up. Also, by way of example, a major issue is the cost and time it takes install one of these enclosed combustion systems. The current combustors are typically shipped on large flatbed trucks to remote locations in multiple large pieces that require a crane and an operator to offload. These large pieces require several men and heavy equipment to set in place. Due to the remote locations of the typical installation the cost for labor and heavy equipment is at a premium. Thus, there are numerous deficiencies and shortcomings in these known devices, systems, and methods.
The technology disclosed herein has a unique construction design, is lower cost, lightweight, efficient, with interchangeable panels and burners for varying the capacity and is easily installed by two technicians with basic hand tools. For example, the system is made of several interchangeable, lightweight stainless-steel panels that are precision cut for accuracy and repeatability and formed to add strength and rigidity. These panels, along with the gas train, burner manifold, and burner management system (items required to be a complete combustor system) are shipped in a crate that can be delivered in the back of a standard full-size pickup truck. The lightweight panels can be handled by two men and the entire system can be assembled in about one hour with hand tools.
Also, by way of example, another issue that is a common concern among current enclosed combustion systems is their efficiency. The Environmental Protection Agency (EPA) ruling NSPS OOOO & OOOOa 60.5413(d) requires that and emissions control device must be tested using Propylene gas. Propylene is used due to its nature of being heavier than air and very difficult to destruct through a natural draft combustion at low inlet pressures. The majority of the applications where these combustion devices are used are low pressures typically <2-4 oz./in̂2. The majority of the combustors on the market today have difficulty completely destructing this gas at this low-pressure range. This is witnessed by dark smoke exiting the outlet of the combustion stack.
The technology disclosed herein is designed with combustion efficiency as a top priority. This technology uses a burner manifold with multiple natural draft burners. Each individual burner on the manifold was engineered to draw in the proper amount of air to mix with fuel to provide stoichiometric combustion.

Additional corner supports, such as 120, can be utilized to secure tiers together and to secure the lowest tier 108 to a base surface. Panels 110, 116 may also include one or more handles 114.
A plurality of fasteners 200 are used to couple interchangeably in modular form the second polygonal tier 106 to the first polygonal tier 108. The first and second polygonal tiers 108, 106 collectively form a vertical, columnar, polygonal stack within which to flame combust combustible vapors.

The fourth plurality of panels is disposed on top of the third plurality of panels, vertically extending the enclosed combustor 100. A plurality of fasteners is used to couple interchangeably in modular form the fourth polygonal tier to the third polygonal tier.
