The following is diagram of where our Airsweep® material activation system, Dazic® zero speed switches, and Acousticlean® sonic horns can be used in a co-gen plant. If you’re not running a co-gen plant, send us your process layout and we can customize a diagram for you.
Bituminous Coal is crushed prior to being fed into the combustors. It is mixed with limestone in the combustion zone of the boiler.
A strong upward flow of air holds the fuel and limestone particles in suspension in the combustion zone. As the coal burns, sulfur dioxide is absorbed by the limestone and the lighter particles move upward in the Combustion Chamber.
Ash and hot gases at 1560°F flow out the top of the combustor to the hot cyclone. The gas exits the cyclone to the convective pass. Partially burned fuel and ash pass from the cyclone back to the combustor for recombustion. Thus the combustor achieves a high degree of fuel efficiency.
Hot exhaust gas from the combustor pass over banks of water and steam piping helping to produce the steam for the turbine.
Ash taken from the cyclones heat the final reheat and superheat steam then returns to the combustor. This is the steam that powers the turbine which spins the generator to produce electricity.
After giving up most of its heat, the exhaust gas from the convective pass is routed through ducts to fabric – filter baghouses. These act as huge vacuum cleaners and collect almost all the fine particulate for ash disposal.
A single shaft, 3600 rpm, condensing turbine. Main steam to turbine is 1,345,000 lb/HR at 1,890 psig, 1005°F, and reheat to 1005°F.
Ash is currently sent to a mine site via fully contained rail cars or trucks, where it is beneficially used to reclaim these sites.

AirSweep installation was easy, and the units have saved the company a lot of man hours. My experience totally exceeded my expectations – a 10 out of 10!
The AirSweep installation was pretty straightforward and I would absolutely recommend it. In fact, we are looking into expanding to use the system in other parts of our plant.
We are experiencing a 62.52% reduction in flour flush and 42.50% reduction in labor, all directly attributed to the AirSweeps…the flush material reduction alone is around $200K. Pretty awesome little devices!
As a distributor, we like that Control Concepts, Inc. takes risks and will try new things to make our customers happy. They want to ensure success, and the quality of the Airsweep for tough and sticky materials is superb. We have been very happy with our projects and look forward to a long and fruitful partnership.
