Presentation
Research Project

Overview

The Super Boiler technology and results of a field demonstration of the 300hp Super Boiler at Clement Pappas, Ontario California will be discussed.  The Super Boiler is a compact two pass firetube boiler with a patented two stage combustion system with interstage cooling to achieve low emissions (single digit NOx) at 1.5% to 2.0% O2 in the stack.  A patented Transport Membrane Condenser (TMC) heat recovery system is employed to recover heat and water from the flue gas to the boiler feedwater to achieve 92% plus steam to fuel efficiency.  Operating results of commissioning the Super Boiler last year and extended duration field test program show the significant fuel and water savings, and reduced emissions of the Super Boiler.
