摘要： The present invention relates to a method of producing steam at a digester plant of a chemical pulp mill. Black liquor is discharged from the digester at a first temperature and pressure. The black liquor is treated in a flash tank for generating flashed black liquor and flash steam at a second temperature and a second pressure, which are lower than the first temperature and pressure. The flashed black liquor is taken for further treatment to the evaporation plant. The flash steam is led to an indirect heat exchange contact with clean liquid in the reboiler for boiling the liquid and for generating steam. The steam is led from the reboiler into a fan or compressor for increasing the steam pressure to a third pressure, which is higher than the second pressure and for adjusting the pressure of the steam in the flash tank. Steam at a third pressure is used for pretreating comminuted cellulosic fiber material, such as chips, prior to cooking.

摘要： 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.
