KMW - Biomass Unit
From Biomass
Bioenergy is a carbon-neutral, environmentally friendly, sustainable energy source that has proven potential to relieve a significant portion of our reliance on fossil fuels. In North America energy from Biomass is critically underutilized and represents a tremendous opportunity for industry and individuals to take control of energy production costs and environmental impacts.
Product Details
With the continuing rise in the cost of fossil fuels and concern over the environmental impact of our increasing energy consumption, energy from Biomass is increasingly recognized as the anchor for a strong future in renewable energy production. There is an abundance of resources available in North America and the availability of suitable and under-utilized farmland fit for the growth of energy crops make the potential for Bioenergy to positively impact global warming and economic growth incredible.Bioenergy can also turn the increasing problems with municipal waste in our cities into economic benefits and make a significant contribution to energy production.
With proper sorting and an efficient, a state-of-the-art Waste-to-Energy plant can reduce the strain on our overfilled landfill sites while producing energy with emissions that easily fall within the most stringent guidelines in Canada. Europe is at the forefront of Waste-to-Energy production and North America is well on it’s way to embracing the idea as the proven benefits continue to roll in from the ongoing studies and the old notions of incinerations plants melt away opening up to clear understanding of today’s technology.

- Residues from rendering plants, ethanol/biodiesel production plants
- Construction sites, land clearings
- Husks/shells from grains, peanuts, walnuts, cotton seeds
- Peel from citrus fruits
How It Works
1. Fuel Handling
The fuel handling involves extraction of biomass from a storage and then transported to the fuel metering bin adjacent to the combustion system. The equipment to reclaim the fuel from the storage is of the live bottom floor design pioneered and patented by our previous parent company. The floor stokers are powered by a hydraulic system and its sturdy design has proven to be very reliable with low maintenance requirements. The fuel transport system includes conveyors of screw (auger), chain or belt type depending on the fuel feed rate and size characteristics of the material.
2. Combustion System
Fuel is metered automatically into the combustion system, which features a sloping grate floor. The fuel is then evenly distributed on the grates where our unique reciprocating grate design gently advances and agitates the fuel down the slope. The carefully designed refractory lining in the combustion chamber acts as a heat sink (thermal flywheel) and heat reflector to maintain the proper cell temperature to remove any moisture present in the fuel and to sustain the gasification process.
Moisture evaporates and volatile gas is released. Secondary (overfire) air is injected to initiate the second stage combustion. Primary (underfire) air mixes with the remaining fixed carbons (charcoal) to complete the combustion process. Our unique grate cycling pattern creating the optimum fuel bed profile together with complete combustion air control achieves the highest degree of efficiency resulting in minimal emissions.
3. Energy Recovery (Boiler)
Heat generated by the combustion system in the form of a hot fluegas is transferred to the appropriate medium (hot water, steam or thermal oil) in the heat recovery unit for use in space heating, process or electric generation. KMW boilers are selected for long, dependable service life.
4. Ash Handling
Collected fly ash together with grate ash is transferred by ash handling conveyors and deposited into a container. The fully automatic ash handling system guarantees a safe and clean operation.
5. Emission Control System
Multicyclones, wet scrubbers, and electrostatic precipitators can be utilized for emission control. The emission control system is carefully selected to meet relevant regulations and protect our environment.
6. Control System
The computerized control system efficiently controls and monitors all components of the entire system. It allows the operator to easily modify parameters and setpoints to adjust for changes in the fuel characteristics to maintain a high performance.
KMW Bioenergy Systems are typically constructed in 6 major sections that can be supplied in sections, or as a whole.
