Large Wood Waste Burner

The Merris WX-8 Wood Waste Burner is an advanced and highly efficient solution for large-scale wood waste disposal, designed with an emphasis on sustainability and superior performance. Building on the success of the WX-6 model, the WX-8 features a larger 30' overall length, 21.5' long burn box, and 4.11' width, providing a significant 25% increase in capacity. This innovative design allows the WX-8 to handle approximately 6-8 tons per hour, making it ideal for demanding applications.

At the core of the WX-8 is its robust eight-panel burn chamber, engineered for exceptional durability and combustion efficiency. The WX-8 is powered by a reliable Yanmar 53 kW Tier 4F engine, which includes a technical clutch and fan system for optimal performance and energy efficiency.

In addition to its outstanding waste processing capabilities, the WX-8 produces biochar as a valuable byproduct. This eco-friendly feature not only contributes to reducing environmental impact but also offers a sustainable resource that can be repurposed in agriculture or carbon sequestration efforts.

The air curtain burner is highly efficient machine for disposing of wood waste and creates no smoke.

Machine Layout

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)
