Steaming Hot Idea Gets $200,000

A Queensland company is to develop what it hopes will be the world's most efficient commercial steam generator with the help of $200,000 in start-up funding from the Queensland Sustainable Energy Innovation Fund.

Delafield aims to dramatically reduce the fuel consumption of industrial boilers by converting about 95 per cent of fuel energy into useful steam.

"Large amounts of fuel are used to generate steam in food processing factories, laundries and hospitals, which contributes to greenhouse gas emissions and pollution," said Environment minister Vicky Darling.

"Despite all the advances in recent years, even the most efficient boilers rely on the same basic technology used for the past 150 years.

"Delafield is developing a ‘pulse detonation steam generation' technology which is set to reduce fuel consumption and emissions by up to 20 per cent for many commercial and industrial steam processes. This new technology will set the benchmark for the world's most efficient combustion technology for commercial steam generators."

The technology works by burning the fuel in short pulses, thousands of times per second. Turbulence created by the resulting pressure waves transfers heat more quickly to the surrounding steam tubes than in a conventional boiler, where typically 20 per cent of the heat energy is lost as wasted heat retained in the exhaust gases.

Since 1999, the Queensland Sustainable Energy Innovation Fund has delivered over $9 million to Queensland businesses to develop technology that reduces the use of fossil fuels or water, leads to more efficient energy use or enhances the use of renewable energy sources, said the minister.
