Mitsubishi Power | Boilers
Delivering Boilers with world-leading quality and performance. Boilers are key components of thermal power plants. They convert the chemical energy contained in fossil fuels such as coal, oil and gas into thermal energy through combustion reactions and use the resultant high-temperature and high-pressure steam-based thermal energy for supplying steam turbines used in power generation.

The staged-air angle was adjusted from 45° to 20° on a down-fired 600 MWe supercritical utility boiler suffering from superheat and reheat steam temperatures operating at below their designed values. This modification was expected to elevate the flame kernel position and increase the combustion share in the upper furnace, thereby raising superheat and reheat steam temperatures. To evaluate
