Integrated SCR Vaporization

PIONEERING CHANGE In 1999, TEI pioneered integrated vaporization of ammonia and urea for SCRs, eliminating separate vaporization skids, electric heaters with control functions integrated into the SCR PLC, simplifying control architecture using TEI’s proprietary WAV or COOLWAV designs, or direct injection

Direct Injection

For industrial, boiler, or engine systems, TEI uses its unique dual fluid nozzle to produce a very fine high velocity mist for rapid vaporization and thorough mixing.

TEI’s Wav System

This design uses hot gas extracted from the exhaust stream, directed through a vaporization chamber equipped with TEI’s
proprietary dual fluid nozzle. The vaporized mixture is then introduced using TEI’s “H HEADER” AIG. An injection blower
is used where needed- not always required.

TEI’s Cool Wav System

For gas turbine systems requiring tempering air, this system uses turbine exhaust heat and pressure to create flow through the vaporizer chamber. This mixture is injected into the tempering fan Inlet, for mixing with tempering air, and delivery through TEI’s plenum system.
