MoistTech Corp. Officially Introduces Sensor to Waste

For the first time, MoistTech Corp. will debut its state-of-the-art Near-Infrared (NIR) technology at the RWM Exhibition in Birmingham this September. Energy from Waste is a solution capable of diverting materials that can’t be recycled away from landfill, as well as one that offers practical ideas to help meet modern-resource needs. RWM is the leading recycling and water & energy waste management event in the UK – showcasing the latest innovations shaping the sustainability sector to the industry’s most influential names and organisations. 

The IR-3000 series sensor has an ideal use for the waste-to-energy industry providing real time results and allowing for immediate line adjustments. In waste-to-energy facilities, controlling the ash residue is a critical concern of plant operators. After combustion, the ash residue that is left, is sprayed with water to reduce dust and odors which is then transported to landfills/moonfuls. However, too much or too little moisture can create several problems for waste-to-energy plants. By integrating MoistTech’s IR3000 online NIR Moisture Sensor into the process, processors can monitor and control 100% of the ash.

Continuous Improvement with MoistTech

Managing the ash residue is important step for many reasons at incineration facilities around the world. From minimizing the possibility of ash dust inhalation and ingestion of employees, to preventing ash being absorbed into the environment, as well as, to lowering transportation costs due to weight. With MoistTech’s NIR Moisture sensor operators will be able to instantly and continuously measure ash moisture and control these problems.

Preventing airborne dust and controlling weight of the ash, MoistTech recommends installing a sensor after combustion and moisture spray. From past installations and depending on the matrix of the ash, the optimum moisture range is 15-18% with a target of 15% for control of dust and weight of the ash. The moisture content lowest point is 12-14% before the ash becomes airborne and above 25% moisture the ash turns into mud that contains surface moisture (liquid) making it very heavy and expensive to haul away.

Typical accuracy is about ±0.2% for ash moisture applications with a moisture range of 0-30% moisture. The sensor should be installed several inches above the conveyor belt. Once installed operators can continuously monitor the process and control the moisture content either manually or automatically. For monitoring and control, the sensor(s) can be directly connected to the users PLC or any laptop. Ethernet 4-20 ma are included as well as our high-tech Windows operating software. DPM-Digital Panel Meter and a Color Touch Screen Operator Interface are also available as read-out options.
