摘要： A novel processed vapor make-up water subsystem that uses a make-up water boiler to boil and purify make-up water and its method of use are described. Upon vaporization, dissolved solids remain in the liquid water in the bottom of the make-up boiler and the solids free steam is introduced into the main boiler loop through a deaerator. Periodically, the water in the bottom of the make-up boiler is blown down when the amount of dissolved solids in the water reach a predetermined level.

摘要： There is disclosed a control apparatus for operating any one of a plurality of parallel connected boilers as a lead boiler, with the others operating as lag boilers. The control apparatus enables a lag boiler to assist the lead boiler during a prolonged operating period to share the burden and the therefore prolong equipment life and increase system efficiency. The control apparatus enables each boiler to serve as the lead boiler while employing full modulation, other boilers such as the lag boiler also employ full modulation. The control apparatus also causes an automatic switch over between boilers after a malfunction of one of the boilers in a rapid time.

摘要： A system is provided to optimize multiple boiler plant systems having mixed condensing and non-condensing boiler groups. The system advantageously employs the independent groups of boilers depending on preset conditions under control of a system control unit. The preset conditions are checked against operating conditions of the boiler plant, and a system control unit controls which of the groups of boilers is the lead and which is secondary. In some instances, both groups of boilers may be utilized under heavy load. Further, effective switching between groups and within groups is also provided to minimize unnecessary repetitive boiler operation.

摘要： A method, apparatus, and system and operation of surface equipment to generate steam while reducing the quantity of boiler blowdown and thereby increasing the amount of feedwater that is re-used or re-cycled in generating said steam. The present invention teaches that, on a sustained basis, the blowdown stream at the outlet of a once-through steam generator can be routed to the inlet of a second once-through steam generator that is in series with the first, that blowdown stream can be used to generate additional steam in the second once-through steam generator and further reduce the amount of blowdown, and that this can be accomplished without need of any treatment that reduces hardness or silica levels of the blowdown stream prior to its entering or during its entry into the inlet of the second once-through steam generator. The output of this second steam generator is a substantially dry saturated steam vapor stream and, complementarily, a blowdown stream whose mass rate has been reduced substantially from that of the blowdown stream exiting the first steam generator.

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.
