The present invention is directed to a method and apparatus for controlling rapping of heat exchanging surfaces based on the heat transfer coefficient of the exchanger systems.

Controlling rapping cycle

A process and apparatus for the combustion of carbon-containing fuel in a reaction zone, with the products of combustion being removed from the top of the reaction zone and the slag from the bottom of the reaction zone. The reaction zone is separated from the bottom of the reactor by a partition wall having a central opening through which the slag is removed. The central opening is maintained open by a cylindrical member that is mounted below the partition wall and moved upwardly to clear the opening.

Process and reactor for the combustion of carbon-containing fuel

Moving bed reactor provided with conical catalyst bed supporting means, which are in communication with vertical channels below the cone(s) and provided with screen walls for the removal of reactor effluent, wherein for increasing the sieve area the channels are ring shaped, both walls having a screen area and/or are provided with intermediate double-walled partitions bearing screen sections in each wall.
