2020-7-2Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14. Roughly 50 of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50 losses are carbon loss and dry gas loss.

2019-11-29Although more than double the global average rate of energy efficiency improvement, this was the slowest rate of improvement in China since 2011. Energy efficiency gains were not enough to offset the effects on energy demand of increased coal-fired electricity generation, called upon to service economic growth of 6.6.

2020-6-30The conversion efficiency of a photovoltaic PV cell, or solar cell, is the percentage of the solar energy shining on a PV device that is converted into usable electricity. Improving this conversion efficiency is a key goal of research and helps make PV technologies cost-competitive with conventional sources of energy.
