Comments on: Clean Coal power ??? http://www.savesandakan.com/clean-coal-power/ "Massive Natural Heritage Destruction at Seguntor - Site for the Sandakan Coal - Fired Power Plant" Tue, 18 May 2010 01:57:15 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: Christopher Chu http://www.savesandakan.com/clean-coal-power/comment-page-1/#comment-1862 Christopher Chu Fri, 13 Nov 2009 05:41:40 +0000 http://www.savesandakan.com/clean-coal-power/#comment-1862 The shortage of power can be relieved in part by the use of combined cycle technology where the thermal efficiency is raised to 60% from the current 35% maximum. When I visited SESB and another private power plants in Sandakan in 2007, neither was using this but the waste flue gas was immediately discharged to the atmosphere at 500 deg C plus. When the engineer in charge showed me that, I thought, what a waste. To-date, I am not sure if the plants are still using the simple once-through steam generation, because if the thermal energy is recovered the power plants' capacities can be increased by 50%. KKIP's Powertron was supposed to get an upgrade to this 2 years ago. I wonder if they have done it. Clean coal technology is only permitted in the UK if it accompanies Carbon Capture and Storage. 1-km high 120-m diameter Solar Chimney Power Plants are being erected in Spain and China. Why not in Sabah? Extended Geothermal energy is being exploited in USA by digging deep to draw Earth's inexhaustible amount of heat underground. This can be used.
