Ash sticking tendency is more in spiral water wall in comparison of vertical wall.

Alstom licenses supercritical coal boiler technology to India power plant builders

A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power. This page was last edited on 3 Octoberat Water passes below the critical point as it does work in a high pressure turbine and enters the generator’s condenserresulting in slightly less fuel use and therefore less greenhouse gas production.

Enthalpy Less More Sp.

Technically, supercrritical term “boiler” should not be used for a supercritical pressure steam generator as no “boiling” actually occurs in the device. This could be obtained at a throttle valve located downstream of the evaporator section of the boiler.
