Fin TUBE Heat Exchanger

Solid Oxide Fuel Cell

OverviewResults

Many industrial applications require heat transfer from a “dirty” gas stream

Initial performance is acceptable but fouling soon occurs and heat transfer rates diminish

Hot, dirty process gas flows through the center of each tube with a spiral cleaning ribbon

Contamination builds on the tubing walls over time and heat transfer performance declines

Control system monitors performance deterioration and initiates a cleaning cycle

Cleaning process will take place continuously, eliminating the need for scheduled downtime to clean heat exchangers

RequirementsApplication
  • Downtime is costly, so must limit work stoppage
  • Bypassing or adding a second HX loop can be expensive, so that’s not an option
  • New, continuously cleanable Fin-Tube design concept
Overview

Solid Oxide Fuel Cells (SOFC) are electrochemical systems that produce electricity from oxidizing fuel at high temperature rather than combustion.

In contrast, common combustion-based generation is only able to achieve 30-40% fuel efficiency

SOFCs provide high power efficiency, fuel flexibility, very low emissions, and competitive costs

Results
The HRI heat exchangers help the system achieve exceptional fuel efficiency (greater than 60%) by recycling process generated heat
Generation TypeElectrical Efficiency
Reciprocating Engine35-40%
Gas Turbine30-40%
Nuclear Power33-37%
Coal Fired Plant33%
Solid Oxide Fuel Cell60+%
