The Phoenix DETB Advantage

Diesel Exhaust Treatment Burner, based on Phoenix UCB technology

The Phoenix DETB is a diesel exhaust treatment burner based on the company’s proprietary UCB (Ultra-clean burn) technology. It is designed to lower the cost of particulate trap regeneration by utilizing waste oil products as a heat source for burning-off soot particles rather than using premium priced low-sulfur diesel fuel.

Economic Benefits

By 2010 global mandates to reduce and control Nox and particulate matter in virtually all engines will require the use of expensive exhaust treatment systems.

Along with the initial high purchase price of the equipment is an ongoing maintenance overhead. Since particulate matter requires elevated temperatures for purging the filters, regenerative burners will increase diesel fuel usage by about 2% across the board.

This translates into a global annual increase of about 2.4 billion gallons (diesel fuel) or roughly $3.6 billion USD in lost transportation revenues.

The Phoenix DETB is able to save end customers that same amount by using waste products normally discarded into landfills.

The Phoenix DETB is the only exhaust treatment technology that can pay for itself in the first year of use – and pay back the cost of the entire exhaust treatment system over the life span of the vehicle.

How It Works

The Phoenix DETB is a technology designed specifically for the diesel exhaust treatment industry, based on PNGinc’s extensive research and development efforts in fuel processing. The resultant UCB (ultra-clean burn) technology is the foundation for the diesel exhaust treatment burner, and is a key technology for 21^st century sustainable growth.

The DETB operates in place of standard diesel-fired regenerative burners, providing the required (approximately) 1,200 degree F. heat at 130,000 btu, for burning off the soot in the particulate trap.

Instead of using premium diesel fuel, the DETB uses filtered (blended) waste oils from an auxiliary tank. The waste oil enters a pyro-catalytic chamber (in the DETB) where it is broken down, or converted to short-chain molecules – mostly methane, methanol, and CO – and subsequently burned as cleanly as natural gas.

An embedded processor and sensors control the burn process, guaranteeing the highest efficiencies and ultimately the cleanest burn. (Diesel fuel burns more cleanly in the Phoenix DETB.)
