Waste-Fired Boiler Systems
Petro Energy Man develops Waste-Fired Boiler Systems that convert thermal energy from difficult waste streams into useful steam.
Waste-fired boilers operate in considerably more aggressive environments than conventional natural-gas-fired utility boilers.
Major Technical Challenges
Waste combustion may expose boiler pressure parts to:
Chlorides
Alkali Compounds
Heavy Metals
Aggressive Deposits
Ash
Particulate Erosion
Slagging
Fouling
High-Temperature Corrosion
Variable Furnace Conditions
Furnace Design
Waste-fired furnace design considers:
Fuel Moisture
Heating Value
Fuel Composition
Residence Time
Furnace Temperature
Heat Flux
Air Distribution
Ash Behavior
Slagging Potential
Corrosion Protection
Where required, corrosion mitigation may include:
Inconel 625 Weld Overlay
High-Alloy Materials
Protected Waterwalls
Corrosion-Resistant Superheater Materials
Appropriate Tube-Metal Temperature Control
Refractory Systems
High-temperature and erosive regions may incorporate:
Silicon Carbide Tiles
High-Alumina Refractory
Wear-Resistant Linings
Fouling Control
Continuous operation requires effective cleaning.
Possible systems include:
Steam Soot Blowers
Pneumatic Cleaning
Mechanical Rapping
Water-Jet Cleaning
Online Cleaning Systems
Boiler Configuration
Waste-fired systems can be engineered around:
Water-Tube Boilers
Grate-Fired Systems
Rotary-Kiln Incineration
Fluidized-Bed Combustion
Waste Heat Recovery
