Incineration vs. ERG WTE
Burning garbage to reduce waste has been a common practice for decades. But while traditional incinerators did a reasonable job of removing garbage from the ground, they were notorious for putting pollution back in the air. Modern Waste to Energy (WTE) plants have evolved significantly from the incinerators of the past. A state of the art ERG plant will burn municipal, medical and even hazardous waste, with complete combustion, generating clean, green, affordable energy.
Why choose an ERG Waste to Energy Facility?
- ERG’s Material and Municipal Waste to Energy Power Production Facilities have a long history of building the best, rugged, and low cost solutions for Waste Stream Power Production. Since 1979, there have been over 300 units installed.
- ERG has not only met but also exceeded the strictest environmental regulations in the world.
- The ability to handle multiple types of fuel sources, and sizes of such fuels without processing, allows lower fuel cost preparation.
- Monitoring plant operations both at the plant and remotely allows for safe, continuous operation.
- ERG provides extensive training for employees at the plant.
The ERG WTE Process
- The process begins with the delivery of the feedstock (waste). The trucks come to the facility to first be weighed in next to the receiving building. Trucks then drive in to the receiving building where they unload their waste. They the drive back to the scale house to be reweighed and leave the facility.
- Once the waste is received into the building, it is spread out on the floor to be inspected for disallowed materials. The waste is then loaded with a front-end loader and dropped into the shredder, shredded waste is then conveyed through a trommel where it is mixed and dried on its way to the primary chamber. A three-day supply of waste is maintained at all times.
- The primary chamber is constructed from ERG’s patented combustion chamber panels. The primary combustion (gasification) chamber can withstand temperatures up to 1,648 degrees C°. Primary and secondary air is injected through ports below and above the fuel entrance level.
- The high temperature combustion of carbon based feed stock results in a reduced volume of over 98% and a reduced weight of over 90%. Bottom ash is removed from the incinerator and can be mixed with cement and gravel to produce building materials.
- Flue gases are sent to the heat recovery and steam generator systems. Cooled gases are filtered in a bag-house and/or Micromist Scrubber, depending on the wastes being burned. Gases exiting the plant are colorless and exceed even the strictest environmental regulations
- Energy output from the Waste to Energy Plant can be as high as 24 MW, delivered to purchaser, assumed by the local and/or federal power grids. The 24 MW of power is provided via a single 24 MW, two 15 MW, or turbine generators, depending on site specific requirements.The entire plant relies on computerized monitoring and analysis to regulate temperatures; fuel, gas flow and waste rates are regulated to ensure the most efficient production of electricity and consumption of waste fuel.
ERG WTE Plant Flow
Primary Combustion Chamber:
The Primary Combustion Chamber is 20′ diameter x 60′ tall. It contains the ERG refractory V-hearth, computerized combustion, fuel, feed and ash handling, and temperature maintenance and hydraulic ash removal.
The Secondary Chamber is a multiple high temperature Cyclone. Crossover ducts transfer incinerated materials from Primary Chamber to Cyclone Unit,. Cross over ducts pass hot gasses to the heat exchangers.
Feed and Ash Handing:
The Feed and Ash Handling is an automatic waste loading system, whereby ash removal rams with hydraulic cylinders and control valves deliver ash to the ash recovery house.
Gas Cooling I Energy Recovery:
Two Boilers, convert 150,000 lb./hr. each, built to ASME standards, with standard trim, including low water cutoff, blow down, safety relief valves and clean-out doors.
Power production is delivered by the Turbine/Generation sets. The system is capable of producing 24 MW while operating at 80% capacity.
