How the Biomass Boiler System by Messersmith worksWatch a video of the Messersmith system in operation.
- The delivery truck unloads fuel into a large storage bin.
- The traveling auger removes biomass fuel from the storage bin...
and places this fuel onto a belt conveyor.
- The belt conveyor delivers the fuel to the metering bin.
- A chip sorting device automatically removes oversized fuel before it enters the metering bin.
- The traveling auger and belt conveyor run in response to level sensors on the metering bin.
- The speed of the metering augers is varied by the control panel in order to modulate the boiler output. The turn down ratio is 10 to 1.
- The combustor has sloping grates that receive fuel from the stoker augers.
- Preheated underfire combustion air is inserted up through the grates and into the fuel.
- Preheated overfire air is inserted through the refractory lined walls of the combustor.
- Both the volume and location of combustion air are determined by the control panel to match the fuel entering the combustor.
- This produces a clean, efficient burn that consumes both the fuel on the grates and the volatile gases driven off the fuel. Carbon Monoxide emissions are less than 100 ppm.
- Particulates are removed from the flue gas by equipment as simple as a cyclone,
or as complex as an electrostatic precipitator, to be certain air quality requirements are met.
- The induced draft fan maintains a negative pressure in the combustor and discharges the flue gas out of the stack.
- The control panel manages the entire process and monitors all equipment for proper operation.
Messersmith systems are known for their simple, robust mechanical design that provides the operator with low maintenance and low downtime. This design, combined with state-of-the-art control technology, results in a user friendly system that can be viewed remotely by computer or smart phone.
