    Abstract: A method and a system for monitoring the mass changes of a heat exchanger bank of a steam boiler. The heat exchanger bank is supported by hanger rods and support beams to the frame beams of the steam boiler. In the method, the web plates of the support beams are provided with strain gages for measuring the changes in the strain state generated in the support beams by the mass of the heat exchanger bank. The system includes strain gages fixed to the web plates of the support beams for measuring the changes in the strain state generated in the support beam by the mass of the heat exchanger bank, data logging means for logging the measurement data and a computer or a corresponding calculation unit for processing the measurement data.

    Abstract: A method and apparatus for cleaning heated surfaces with substantially constant progression of a jet cleaning medium. The invention monitors the rotational and translational position of the lance tube and is programmed with a schedule of lance tube rotation rates and blowing medium discharge rates for the specific configuration of the heated surfaces. Based upon the rotational and translational position of the lance tube and the distance the jet travels before impinging upon the heated surfaces, the rate of rotation of the lance tube is varied throughout every rotation to maintain substantially constant progress of the jet across the heated surfaces.

    Abstract: A steam generator for supplying steam to cooking equipment comprises a water-filled boiler comprising an automatic, level-regulated water emission, a steam discharge for automatic introduction of hot steam into a cooking chamber for the cooking equipment as needed, a heating unit operating at intervals and a decalcification arrangement having a water drain arranged close to the floor and to a side wall of the boiler for, as needed, at least partial emptying of the boiler for the purpose of flushing-out lime particles that flake off and collect on the floor of the boiler. Preferably, the decalcification arrangement comprises an arrangement for generating a flow in the steam generator that automatically kicks in at preferably adjustable intervals dependent on the operating duration and/or temperature of the heating unit to supply water to an elimination device. The arrangement for generating a flow can encompass the eliminating device and can be either a suction tube having a drain provided at the floor of the boiler; a flushing pump having a flushing admission lying diametrically opposite close to the boiler wall; or a steam pump that comprises a cooling device for the precipitation of the line particles.
