BFB boiler for high-moisture biomass - South America

Complete BFB boiler design for a biomass facility in South America, handling high-moisture fuels with custom combustion and heat transfer engineering.

Biochar Facility Debottlenecking & Capacity Expansion

Debottlenecking

Biochar Facility Debottlenecking & Capacity Expansion

A comprehensive pyrolysis yield analysis with heat and mass balance to identify process and equipment constraints and engineer a path for tripling biochar production capacity.

Biomass boiler capacity limits identified across 17 subsystems

Debottlenecking

Biomass boiler capacity limits identified across 17 subsystems

Component-level performance and capacity assessment of boiler, fans, ESP, fuel handling & metering, ash handling, economizer, air heater, multiclone and emissions controls systems. Boiler and appurtenant systems were modeled at existing and target conditions to identify bottlenecks and areas for improvement, required to achieve target conditions. Capital cost estimates were then provided for each option for determination of the best option to proceed with.

Engineered Lower Sidewall Header Repair Avoids a $3–4 Million Replacement

Detailed Engineering

Engineered Lower Sidewall Header Repair Avoids a $3–4 Million Replacement

CPE developed and coordinated an excavate-and-repair procedure supported by detailed lower sidewall header stress calculations performed in strict accordance with ASME BPVC Section I. The repair avoided a full replacement estimated at $3–4 million and an estimated 8 to 10 weeks of forced outage.

Steam contamination pathway traced to source

Root-Cause Investigation

Steam contamination pathway traced to source

Multiple contamination pathways identified across the steam and condensate systems. However, the primary driver for the issue was galvanic corrosion in galvanized piping downstream of an RO system. Corrective actions and appropriate metallurgies were identified and deployed.
