An incinerator in US is a waste treatment facility that uses combustion to dispose of various types of waste materials. There are five primary types of incinerators:
General dimensions
The overall sizes of an incinerator include its width, depth and height. The general dimensions influence the layout of the device, as well as its ability to hold wastes.
Capacity
It is the amount of wastes an incinerator can process in a given time duration. The capacity is typically represented in kilogram or ton per hour.
Temperature range
An incinerator's temperature range shows the lowest and highest possible operational temperature. The temperature determines the type of wastes the device can process, as well as its combustion efficiency.
Control system
An incinerator is usually equipped with a control system that regulates its operations. This system can be manual, automated, or a combination of both. Modern incinerators may feature an automated control system that allows remote access and monitoring.
Safety features
These include emergency shut-off systems, safety interlocks and temperature and pressure alarms.
Emission control technologies
They include scrubbers, electrostatic precipitators (ESPs), selective catalytic reduction (SCR) systems and filtering systems for fly ashes.
Power source
An incinerator's power source may be electrical, solar, hydraulic or gas-powered. The type of power source influences the location where the device can be installed.
Routine check
Users should conduct regular inspections on the incinerator. The routine check includes examining and adjusting the combustion chamber, feeder mechanism, temperature control system and waste feeding system. Typical findings from such inspections can be incorporated in the subsequent user manuals.
Cleaning
Generally, an incinerator should be cleaned regularly to get rid of ash residues and clogs. The cleaning process affects the incinerator's air flow, thus impacting its combustion efficiency and overall performance.
Replace parts
Users should replace the worn-out components of an incinerator on a consistent basis, including its gaskets, seals and pipes. Also, the emission control devices, such as filters and scrubbers need to be checked and replaced periodically.
Lubrication
Some moving parts, such as the feeder mechanism and cooling fan, need to be lubricated on a consistent basis. Doing this helps to enhance the component stability and reduce the abrasion.
As per the Environmental Protection Agency, 12% of total wastes in the US underwent incineration.
Industrial waste incinerators are used in factories and manufacturing plants to dispose of solid industrial waste from the production process. This can include anything from excess packaging materials to contaminated equipment and components. By incinerating this waste on-site or nearby rather than sending it off to landfills, these facilities can save space and cut transportation costs.
The medical waste incinerator is a facility that is being used to properly dispose of waste generated by healthcare facilities like hospitals, clinics, and laboratories. These places produce sharps, biohazards, and infectious materials that need to be destroyed completely and safely. Medical incinerators are placed very close to these healthcare facilities so that the staff can easily dispose of the hazardous waste immediately and avoid any potential threats to human life. The temperature of these kinds of waste incinerators usually lie around 1000 to 1300 degrees Celsius, which is more than enough to completely destroy viruses, bacteria, and other pathogens.
Pharmaceutical manufacturers use incinerators designed specifically to handle their unique waste streams. These can include contaminated equipment, expired drugs, and packaging materials that cannot be recycled. By incinerating this waste rather than sending it to a landfill or even risking it being recycled, these companies protect brand integrity and prevent environmental contamination.
Construction projects generate large amounts of debris like wood, asphalt, and concrete that can clog landfills. On-site incinerators allow this waste to be converted into ash and energy instead of taking up space far away from the project site. Power produced by on-site units can sometimes even be fed back into the project's electrical grid.
Incinerators are being used to dispose of waste produced by solar farms. Construction and demolition waste made up over 12% of total solid waste in the U.S. in 2018. Solar producers are now using mobile incinerators to get rid of waste caused during solar energy production as they help convert the waste into usable energy. When excess material cannot be reused or recycled, mobile solar farm incinerators reduce both environmental impacts and landfill costs by treating this non-recyclable fraction.
When purchasing incinerators for sale in the US, it is important to consider the features mentioned above. Apart from that, it is essential to research the local and state incinerator regulations to ensure the chosen incinerator complies with the required standards. Furthermore, it is important to assess the potential market and choose an incinerator that satisfies mainstream demands. More businesses may prefer a waste-to-energy incinerator that is likely to reduce their waste disposal costs.
The intended use of the incinerator also influences what buyers will pick. Most people and businesses incinerate their sewage. Thus, a typical incinerator for human waste will be in demand. Since the capacity of different incinerators ranges from small to large, it's essential to evaluate the expected waste volume that potential customers generate.
Customers will also want an incinerator that is easy to install and operate. Therefore, it's essential to choose an incinerator with clear installation instructions and a well-documented user manual. In such a case, training and technical support will be required to ensure a hassle-free setup for the customers.
Since most customers will want an incinerator that is easy to maintain and produces minimal downtime, choose an incinerator that has straightforward maintenance requirements. Also, consider opting for incinerators constructed with durable materials and corrosion-resistant components to enhance longevity and dependability.
Q1: What materials are typically used in industrial waste incinerators in the U.S.?
A1: Incinerator manufacturers in the U.S. mostly build waste incinerators using high-temperature refractory materials and stainless steel. The latter can resist rust for a long time.
Q2: What are the emission controls used in U.S. incinerators?
A2: Modern U.S. incinerators generally have advanced emission control systems. These may include fabric filters, scrubbers, and selective catalytic reduction (SCR) systems among others.
Q3: How are U.S. incinerators monitored?
A3: The EPA or relevant local authorities usually monitor the operation and emissions of waste incinerators in the U.S. They do so using continuous emission monitoring systems (CEMS). These systems may offer real-time data onincinerator emissions. The data may include details on the incinerator's combustion efficiency and air pollutant levels.
Q4: Do U.S. incinerators generate energy?
A4: Some waste incinerators in the U.S. are designed to recover energy from waste through combustion. Such a waste-to-energy incinerator will typically generate electricity using a steam turbine or a similar technology.
