Study Notes
Standalone Incinerators
- Macrotec's Standalone Incinerators are designed for efficient waste disposal, reducing environmental impact.
- The process is continuous, meaning waste is loaded without halting the process.
- Waste is loaded into a primary combustion chamber lined with high-temperature alumina-silicate refractory.
- High-velocity combustion air ensures optimal oxygen mixing and turbulence.
- After initial combustion, combustion products move to a secondary chamber for particulate settling.
- Auxiliary burners maintain and preheat the chamber temperature.
- A tall flue gas chimney removes and disperses exhaust gases.
- This design improves efficiency and reduces emissions.
Incinerator Chambers
- Primary Chamber (Combustion Chamber): Has a large hearth to evenly distribute waste. High-temperature alumina-silicate refractory protects the chamber structure.
- Secondary Chamber (Settling Chamber): Facilitates particulate settling and complete combustion.
Thermal Protection
- Refractory Lining: High-temperature alumina-silicate refractory provides thermal resistance, structural durability, and protection against abrasion.
- Insulation: 100 mm low-density insulation reduces heat loss.
Fuel and Combustion Control
- Auxiliary Burners: Diesel, LPG, or natural gas burners preheat and maintain a consistent combustion temperature.
- Feeding Systems: Manual or automatic waste feeding systems. Manual feeders are cost-effective, while automatic systems prevent overfeeding and enhance safety.
Air and Exhaust Management
- Combustion Air Fans: High-velocity centrifugal or axial fans ensure proper oxygen mixing.
- Flue Gas Chimney: Taller stacks (7-15m) enhance flue gas velocity and dispersal.
Sensors and Instrumentation
- Temperature Sensors: Omega K-Type thermocouples monitor chamber temperatures for efficient combustion and safe operation.
- Pressure Sensors: Honeywell industrial transducers monitor pressure within the chambers.
- Flow Sensors: Siemens or Emerson flow meters measure combustion air velocity, crucial for the proper oxygen-to-fuel ratio.
- Emission Sensors: Testo gas analyzers check CO, NOx, and other by-products in compliance with regulations.
Control and Networking Equipment
- Programmable Logic Controller (PLC): The central controller gathers data from sensors, processes it, and sends commands to actuators for optimal system performance.
- Human-Machine Interface (HMI): Provides visual display of real-time process data, system status, and control options.
- Industrial Ethernet Switches: Facilitate communication between the PLC, sensors, and HMI.
Biomass Fired Incinerators
- Suitable for remote sites where conventional fuels are unavailable.
- Biomass (wood chips, agricultural residues) preheats the combustion chamber.
- Biomass serves as an auxiliary fuel.
- The incinerator is built with two chambers for efficient combustion.
- Combustion air supplied via high-speed fans mixes oxygen with the waste.
- Waste exits through a tall chimney, ensuring complete dispersion of emissions.
Cremators
- MacroBurn Cremators are designed for efficient body cremation, minimizing environmental impact.
- Bodies are loaded manually or with an auto-loader.
- Modulating process burners initiate combustion in a large refractory chamber.
- The secondary chamber ensures complete oxidation of combustibles using high-velocity air.
- The flue gases are released via a tall chimney stack.
Gold Recovery Incinerator
- Continuous-operation incinerator for recovering gold from carbon fines.
- Carbon fines are continuously fed into a refractory-lined chamber.
- High-efficiency modulating burners ignite the carbon fines, oxidizing carbon and leaving behind concentrated gold ash.
- The hot flue gases pass through a high-efficiency filtration unit with ceramic filter elements to capture ash.
