ENERGY RECOVERY AND POWER GENERATION

The ARTEC gasification system produces energy from the various feed-stocks (described above) in the form of hot air for product drying or baking, hot water, steam, refrigeration, electrical power production,
or other uses which normally consume fossil fuels. The amount of energy available from this system depends on the BTU value of the feed-stock and the type of energy driven by the process.

The thermal energy generated by the ARTEC process may be recovered from the exhaust gas through the use of a Waste Heat Boiler (WHB). A WHB system is a heat exchanger system that uses waste heat to heat a medium, whether water, steam, thermal oil, etc.

Small ARTEC systems (less then 10 tons per day (tpd)) would operate using a single primary with the gas being produced for approximately 12-14 hours per 24 hour period.

This energy could be used via a WHB for hydroponics systems, greenhouses, municipal buildings, factories, or any process currently using fossil fuels for heat.

Larger scale systems are designed to use 3 or more primaries that are engaged in sequence to deliver the Btu rich gas continuously over a 24-hour period.

FOR EXAMPLE: 100 tons* of MSW = 8.2 MW of thermal energy per hour, based on 4500 (MSW average) btu/lb. We can assume the generation efficiency to be ~20%; therefore, the electrical output would be 1.63 MW/h of electrical power. Using an average electrical power consumption rate of $0.10 per kW(el), then the 100 tons* of MSW a day is equal to $3,912 per day in recovered electricity that can be used or sold back to the grid at a discounted rate.

This non-interrupted supply of fuel can power steam or thermal oil turbines and produce electricity for use in-house or for distribution through the local power grid.
