摘要： A method for operating a recirculating waste heat steam generator is provided, in which in a pressure stage of the recirculating waste heat steam generator, the feed water mass flow is guided on the basis of a specified desired value in order to control the water level in a drum. The method should give a recirculating waste heat steam generator a particularly high degree of efficiency and simultaneously a particularly high level of operational flexibility. For this purpose the thermal input introduced into an evaporator of the pressure stage is used as input variable in the determination of the desired value.

摘要： An evaporation cycle of a natural circulation steam generator. An evaporator is in flow connection with a downcomer pipe and includes a first evaporative section and a second evaporative section connected in parallel with the first evaporative section and arranged at a higher level than the first evaporative section. The evaporator cycle is not associated with another external source of motive force than heat from the gas flow to assist the flow of the water in the evaporator, and the evaporator has a vertically extending outlet collector for collecting the steam and water from the first and second evaporative sections to the riser pipe. The outlet collector includes a lower portion and an upper portion above the lower portion. The first evaporative section is in direct flow connection with the lower portion and the second evaporative section is in direct flow connection with the upper portion.

摘要： An evaporator system comprises an evaporator; a drum; and a pump that are in fluid communication with each other. The pump is operative to create a temporary pressure gradient during start-up of an evaporator system and transport a fluid from the evaporator to the drum prior to the fluid reaching its boiling point in the evaporator. Following the fluid reaching its boiling point in the evaporator, the fluid naturally circulates in the evaporator system.

摘要： A steam generator includes a gas flue having burners for fossil fuel, a gas-tight tube wall with tubes, inlet and outlet headers connected to the tubes, the outlet header being at a higher level than the inlet header, and a down pipe outside the tube wall connecting the outlet to the inlet header. A steam line is connected to the outlet header and at least one heating surface is connected downstream of the outlet header in the steam line. A feedwater line is connected to the gas flue and an economizer is connected upstream of the gas flue in the feedwater line. A regulating device for influencing feedwater flow in the feedwater line detects at least one of: the steam enthalpy in the heating surface or the steam line downstream of the heating surface, the steam temperature in the heating surface or the steam line downstream of the heating surface, the thermal output transfer to the tubes, a ratio of feedwater flow in the feedwater line to steam flow in the steam line, a ratio of injection water flow into an injection cooler connected in the steam line to feedwater flow in the feedwater line, and residual moisture of steam in the steam line.
