Coke-Fired Boiler Systems
Petro Energy Man develops steam-generation systems capable of utilizing petroleum coke and other difficult solid fuels.
Petroleum coke offers significant energy content but also introduces major engineering challenges related to combustion, sulfur, ash, erosion, fouling and emissions.
Fuel Evaluation
Boiler engineering begins with analysis of:
Heating Value
Moisture
Ash
Sulfur
Volatile Matter
Fixed Carbon
Particle Size
Combustion Technology
Depending on fuel properties and project conditions, technology may include:
Fluidized-Bed Combustion
Bubbling Fluidized Bed — BFB
Circulating Fluidized Bed — CFB
Other Project-Specific Solid-Fuel Systems
Combustion Engineering
Important parameters include:
Fuel Feed Rate
Air Distribution
Excess Air
Residence Time
Combustion Temperature
Particle Burnout
Furnace Heat Flux
Erosion Protection
High particulate loading can cause erosion of pressure parts.
Engineering measures may include:
Controlled Gas Velocity
Tube Shields
Wear-Resistant Materials
Ceramic Protection
Optimized Tube Arrangement
Fouling & Slagging
Ash chemistry is assessed to determine:
Deposition Risk
Fouling Potential
Slagging Temperature
Cleaning Requirements
Heating-Surface Spacing
Emission Control
Petroleum coke combustion may require control of:
SOx
NOx
Particulate Matter
Emission-control systems are selected based on project requirements and fuel chemistry.
