Combustion chamber cleaning method, involves blowing compressed air or water to air jet produce angular momentum that is conveyed to air jet, where air jet experiences expansion of distributing angle of specific degrees through momentum

摘要

The method involves blowing air jet (6) to a combustion chamber for improving the after burning process by swirling combustion gases. Compressed air or water is blown to the air jet to produce an angular moment that is conveyed to the air jet. The momentum is produced during operation of a combustion plant for only short period. The air jet experiences an expansion of a distributing angle of 70 degrees through the momentum. Independent claims are also included for the following: (1) a cleaning device for an air duct for generating temporary and/or periodically recurring angular momentum and including twist generating device and control device (2) a computer program product for executing a cleaning method.
