The REKO-SIK-NxT-SW by ESA is a sidewall burner in a self-recuperative body utilizing ESA’s NxT technology. A “sidewall” (or “flat flame” or “wall hugging”) burner traditionally uses centrifugal force to achieve a flame that stays close to the refractory wall, avoiding impingement on the work product. The REKO-SIK-NxT-SW works a bit differently, instead dividing the output flame four ways, thus allowing for the collection of hot gases to preheat the combustion air.
Like all REKO models, the heat exchanger is made from durable silicon carbide and the burner body is insulated to protect against the recovered hot gases. This unique design allows REKO to work in furnace chamber temperatures up to 2,370°F in direct heating applications. The integrated eductor is fitted with an air adjustment valve for ease of control, contributing to the remarkably compact weight and size of REKO when compared to other self-recuperative burners.
Self-recuperative technology allows the recycling of heat that would otherwise escape through the stack. Given that, firing with preheated air ensures more efficient combustion, so you get the most out of your fuel. This means you get more heat and use less fuel, and best of all, you save money.
The NxT series of burners was developed specifically to target NOx and CO emissions, which are the subject of permit requirements across the USA, and all over the world. So when you need the best available technology for emissions requirements, you need ESA.
