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： 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： A boiler control system for boilers fired by solid fuels wherein the fuels are carried through the combustion zone of the boiler on a traveling grate and wherein the air flow for combustion as supplied to the undergrate region utilizes a control of the fuel rate from a deviation of the outlet pressure from the desired value with the control of the air flow to the undergrate region maintained generally in proportion to the steam flow from the boiler with the proportionality being biased from the deviation of the outlet pressure from its desired value.

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.

摘要： A self-regulating exhaust gas boiler intended for the recovery of thermal energy from the exhaust gases of diesel engines or the like, has a steam/water cylinder acting as the water and steam space. There is a convection part acting as the vaporizer and being fitted in the vertical orientation between the steam/water cylinder and a lower cylinder, or the like, and connected to it. There is at least one downcomer interconnecting the steam/water cylinder and the lower cylinder, or the like. At least one valve or corresponding device regulates the amount of water and the water level in the convection part is mounted between the steam/water cylinder and the lower cylinder, or the like, preferably in the lower section of the downcomer. The preferably vertically disposed pipes of the convection part are partly filled with water, the power of the exhaust gas boiler being regulated by adjusting the water level in the convection part by means of a valve on the basis of the different heat transfer properties of water, a water-steam mixture, and steam. The valve can be continuously regulated and/or of the open/shut type. The pipe or pipes connecting the convection part to the steam/water cylinder can penetrate the mantle of the steam/water cylinder at a point above the highest permitted steam/water cylinder water level.

摘要： A safety device for subcritical natural and forced circulation boilers wherein the differential between downcomer fluid temperature and drum saturation temperature is measured and the trend of the differential is determined by computer means on a continuous basis. If the differential approaches a defined limit in its trend in a defined time interval or the furnace tube temperature increases instantaneously, the heat source for the boiler is diminished.

摘要： An apparatus for controlling the drum water level of a drum boiler prevents the boiler system from being tripped off which would otherwise be caused by an excessive fall in the drum water level immediately after the start of load runback, by increasing the real feed water flow rate in such a manner that a feed water flow rate demand signal obtained from the drum water level deviation is corrected by a feed water flow rate increment signal obtained from the amount of load reduction (load demand--load reference after load runback) at the time of load runback. In addition, the fact that the drum water level stops falling and starts to rise is detected, and the feed water flow rate demand signal is adjusted so as to take a medium value between the real feed water flow rate and the real main steam flow rate, thereby preventing the boiler system from being tripped off which would otherwise be caused by an excessive rise in the drum water level.
