Why buy from Machinery Partner?

Usage

Best for
Forestry and land management projects where large volumes of wood waste need efficient and environmentally friendly disposal. Similar to the X5, ideal for large-scale wood waste disposal and biochar production, with enhanced capacity and features for larger projects.
Good for
Construction and demolition sites with significant wood waste generation seeking a convenient on-site disposal solution. More intensive applications like land clearing operations.
Not built for
Incinerating non-wood materials or hazardous waste, as air curtain burners are specifically designed for clean burning of wood and organic waste. Applications that don't require high-capacity wood waste disposal.
Best loader
Large/medium excavator with grapple/thumb

Overview

The Merris WX-6 Wood Waste Incinerator, a cutting-edge solution to wood waste disposal, engineered with sustainability and efficiency at its core. At the heart of the WX-6 lies a robust 18' x 5' x 6' refractory-walled FireBox, meticulously designed to withstand extreme temperatures and ensure the highest levels of combustion performance. Equipped with advanced air curtain technology, the WX-6 generates a powerful, high-velocity airflow over the burn chamber. This innovative feature effectively traps particulates and smoke, allowing for thorough combustion while significantly minimizing emissions and environmental impact. The system expertly reburns particles until they are completely combusted into hot gases, ensuring exceptionally clean burning of wood waste. Beyond its impressive environmental credentials, the Merris WX-6 is highly portable and remarkably easy to deploy. This makes it the perfect choice for a wide range of applications, from forestry and land management to construction sites and remote locations, where efficient and eco-friendly disposal of wood waste is required. One of the most exciting benefits of the WX-6 is its ability to produce valuable biochar, a byproduct that further enhances its eco-friendly appeal by offering a sustainable solution to waste disposal needs. With the capacity to burn up to 4 tons per hour, the Merris WX-6 Wood Waste Burner represents a significant leap forward in waste management technology, delivering performance, sustainability, and convenience in one powerful package.

How It Works

  • Start a fire in the burn box chamber

  • Add wood until fire has taken hold

  • Start engine

  • Turn on fan

  • Add wood waste to the fire and repeat

  • When fire is out (typically over night) clear the charcoal and start burning again

  • To extend the burn, it is common to dig a pit under the box so that more charcoal can built up

Operating Notes

  • It is typical to burn through out the day

  • This is a robust machine and where wood waste is loaded from the top

  • The air diffuser is thick metal pipe and can withstand some abuse of dropping wood into the chamber

  • This is a HIGH temperature machine (paint will peel, etc. due to heat)

Transportation

  • Typically lifted onto trailers or flatbed trucks to transport between job sites

  • Hook lift (i.e. common with roll on / roll off dumpsters) is an option for transport

  • On the job site, the air burner is typically pulled around with an excavator or loader

Why We Like this Equipment

  • Low cost alternative to expensive grinders and hammer mills (if disposal is the main use case)

  • Clean and environmentally friendly (EPA Title V approved)

  • Simple machine to dispose of wood waste, clean lumber, yard waste

  • Bio char post burn material can be used for fertilizer

  • Smokeless burner does not alert neighbors or businesses in the area

EPA Approved

On April 11, 2024, the U.S. Environmental Protection Agency removed title V permit requirements for air curtain incinerators that burn only wood waste, clean lumber, yard waste, or a mixture of these three types of waste. (See in the documents section a ruling on air curtain burners)
