Features of the edm Biomass Boiler
The static grate, with its multi-level primary combustion air to facilitate staged combustion and reduced nox, maintains a good fire bed depth for combustion stability as the incoming fuel progressively pushes burnt fuel off the first stage onto the mechanically activated burnout grate.
Up to 2 hours burnout time is achieved on the over 2 metre long slow moving heavy duty chain grate, resulting in the complete burn out of fuel.
Flame Reaction Chamber
The patent pending flame reaction chamber maximises combustion reaction times, temperatures and turbulence, whilst minimising gas born particulate temperatures and carry over to the heat exchangers.
Triple Pass Heat Exchanger
This is fitted with patent pending open space turbulators which achieve near complete heat transfer in the boiler, low pressure drops and require minimal maintenance.
The unique twin cyclones and lambda controlled exhaust gas recirculation combined together achieve very low dust and nox emissions
The combustion chamber is cast as a monolith in a high density and very durable ceramic and is insulation lined for minimum heat loss.
Robust feed auger with burn back protection temperature sensor, burn back flap and mechanical water quench, avoiding the potential limitations of a rotary valve.
Fine Ash Auger
Bottom fine ash auger to clear all precipitated dust to the common ash discharge point, for ease of ash removal.
Induced Draft Fan
Induced draft fan with air cooled drive coupling.
Forced Draft Fan
Forced draft fan optimises combustion of lower grade fuels. Pressure switch protected operation.
Flue Pipe Connection
Standard flue pipe connection and wide choice of orientation options.
In addition to the features shown above the edm boiler incorporates the following:
- A uniquely designed rugged low energy feed hopper discharge mechanism.
- A touchscreen PLC Inverter control of all motors for optimum efficiency, controllability and flexibility. Single or three phase options available.
