Just some reading for interest's sake for anyone interested.

The nearest power station to Mantle's EL5210 is Yallourn which is approx 6kms away. It uses superheated steam to drive it's turbines. Possibly one tech SE may be looking at implementing in the Valley uses S/H steam.

On the weekend it was quoted "Drop in waste heat temperature is only about a quarter of a degree over 4km". The source of that info is questionable but it's interesting all the same.

Brown Coal Developments

EnergyAustralia/Yallourn is working on a range of projects to utilise brown coal in an environmentally responsible manner in the future.
This included participation in CarbonNet. CarbonNet is Victoria’s carbon capture and storage project that is supported by the
Victorian and Federal Governments, including the Federal Government’s Carbon Capture and Storage Flagships program. In
2011 we completed two pre-feasibility studies as part of our participation in CarbonNet. One was for an integrated gasification
combined cycle power station with carbon capture (IGCC) at Yallourn. The project was based on Mitsubishi Heavy Industries’
high efficiency gasification and gas turbine technology. The second was for a post combustion carbon capture plant (PCC),
together with Loy Yang Power, also based on Mitsubishi Heavy Industries’ technology. We continue to work with our partners
on options that have the potential to significantly reduce carbon dioxide and other atmospheric emissions.
EnergyAustralia also participated in research and development projects with Monash University (chemical looping and oxyfuel
combustion) and Commonwealth Scientific and Industrial Research Organisation (CSIRO) (sulphur tolerant solvent for post
combustion capture) for longer-term innovations that could significantly reduce the cost of low emissions power generation
from brown coal. These projects are sponsored by Brown Coal Innovation Australia and Australian National Low Emissions Coal
Research and Development group. EnergyAustralia is a member of Brown Coal Innovation Australia which supports research
and development activities focused on brown coal.
EnergyAustralia is working with a range of parties to develop technologies and projects to produce coal-derived products,
including coal drying and conversion of brown coal to liquids, gases and chemicals. These offer the potential to add significant
value to brown coal and offer alternatives to electricity generation.

About Yallourn

The power station commenced operations in 1974 with four generating units commissioned between 1974 and 1982.

Every hour 2,400 tonnes of brown coal is used to boil water into superheated steam to drive four turbine generators.

These turbines have a combined capacity of 1,480 megawatts of electricity which is enough to supply around two million homes.

A unique feature of the power station is its three vast concrete cooling towers, once the steam has passed through the turbine, water from the towers cools the steam so it can be pumped back to the boilers and reheated to steam, once again driving the turbines.

Shanghai Electric Power Co., Ltd. 150,000 t/y Lignite Upgrading & Briquetting Project

Tianli took the contract of 150,000 t/y lignite upgrading & briquetting demonstration project for Waigaoqiao Power Plant of Shanghai Electric Power Co., Ltd. which is located in the coal storage yard of Shanghai Waigaoqiao Power Plant. This project was approved in 22nd June, 2011 by the China Power Investment Corporation superior to Shanghai Electric Power Co., Ltd., and the jobsite selection, geographic investigation and civil work were completed in the same year.

The main dryer and briquetting equipment have already been installed and we plan to get continuous test-drive in June 28, 2012.

The site covers an area about 4,000m2, mainly consisting of the dehydrating area, the briquetting area and the wastewater treatment area. Thanks to our international advanced lignite upgrading technology of multi-bed superheated steam fluidized bed with in-bed heat exchanger and high-pressure roll press technology without bond, this project can ensure a reliable production of high quality lignite briquettes.

The total annual output is designed to be 150,000 tons. In addition, the project is also an industrial demonstration platform for large-scale production (windows side by side) and process optimization of various lignite.
