Title: Method for heat and/or power generation at oil- refining, gas-and-oil or gas processing plants
IPC: C10J3/00
Filed: 1999-10-06
Granted: 2000-05-20
Abstract: FIELD: thermal engineering; oil, gas, and chemical industries. SUBSTANCE: method involves at least steam production in at least one steam generator partially due to combustion of gaseous fuel meant for use, among all things, in at least some raw material treatment processes at plant. Novelty is that oil gas contained in raw material and/or fuel process gas emitted during heat treatment of raw material and/or as result of heat destruction processes during treatment of raw materials and/or by-products is used as at least part of gaseous fuel; steam generator or generators are fed with water composed of cooled down and clarified return condensate and chemically treated water introduced in addition in circulating loop and heated by thermal energy released in the course of extraction of residual heat of return condensate during cleaning of the latter. In this way, lower labor consumption and material input is required due to lower discharge of chemically treated water for boilers. In addition, standardizing quality of chemically treated water and condensate with respect to silicon content becomes unnecessary which enables return of 100% of condensate to steam generator so that demineralizing plant with hydrogen/cation exchangers and anion exchangers can be replaced by sodium/cation exchangers; hence, chemically active agents such as sulfuric acid and alkalis can be dispensed with and common salt used instead. EFFECT: improved economic efficiency and environmental friendliness. 16 cl, 1 tbl

Title: Gas turbine engine
Inventor: GOJKHENBERG M M
IPC: F02C7/28
Filed: 2000-11-23
Granted: 2002-07-27
Abstract: FIELD: mechanical engineering. SUBSTANCE: invention is designed for devices organizing operation of seals separating dummy spaces from other spaces at non- stationary modes of operation. With engine operating at non-stationary modes, radial clearances between teeth and their mating members increase. Simultaneously, radial clearance between back tooth and additional back member decreases by the same value. It means that increase in passage area determining leaks past teeth is compensated by decrease in passage area and leaks past back tooth. On the other hand, pressure of cooling air in common space by front dummy space and ring air duct is completely determined by gas pressure in turbine blading which provides stability of turbine pressure at specific mode of operation leading, in its turn, to stability of axial load at the mode. Stabilization of axial loads on compressor and turbine leads to stabilization of axial load on radial-thrust bearing. Constant cooling air pressure differential in swirling device is set corresponding to specific mode of engine operation which provides stability of cooling air flow rate. Such design of device makes it possible to stabilize axial loads of turbocompressor at non-stationary modes of operation by stabilizing air pressure in dummy space of compressor and front dummy space of compressor and front dummy space of turbine. EFFECT: preservation and even increase in energy saving at non-stationary modes of operation. 6 cl, 4 dwg
