New soot blower patent

We have received a new patent grant in the field of steam soot blower optimization.

The invention involves a method to reduce variations in the soot blowing steam flow in a boiler with steam soot blowers which are run in succession after each other, as well as means for control of the soot blowers and the flow of steam through them.

The standard operation procedure of soot blowers implies that pulsations are created in the steam flow at the exchange of soot blowers in operation, which causes undesired stresses in the system and may result in disturbances in other pieces of the equipment connected to the steam system, e.g. lost efficiency in steam turbines. The pulsations are caused by the shutoff soot steam flow during the stop phase of the soot blower in operation as well as the start phase of the operation of the next blower.
