Patent ES-322629-A1 (ES)
Title: Steam power stations
IPC: F01K17/06
Filed: 1966-02-04
Abstract: During normal operation of a steam turbine plant, combustion air supplied by a fan 8 to a boiler 1 is preheated in a heater 4 by steam bled from a turbine 3 while part of the feed water from a condenser 13 is preheated in a heater 5 by further steam bled from the turbine, the remainder of the feedwater being preheated in a flue gas cooler 12. At peak load, valves RA, RE are closed and valves RD, RC are opened, and the combustion air is then heated by an auxiliary combustion chamber 6. Since steam is no longer being bled from the turbine 3 to supply the heater 4, the turbine develops extra power to meet the peak load. The valves RA, RE, RD, RC can be set to intermediate positions at loads between normal and peak. At superpeak load a further increase of turbine power is provided by operating a valve 20 to reduce or stop the bleed of steam to the feedwater heater 5, the feedwater being correspondingly diverted to the flue gas cooler 12 and the heat input to the latter being correspondingly augmented by means of an auxiliary combustion chamber 7 fed by a fan 11. The combustion chambers, 6, 7 operate on liquid or gaseous fuel. A duct 9 with a valve RB enables the heater 4 and combustion chamber 6 to be connected in series. When the boiler 1 is being started up, it can be preheated by the combustion chamber 6. In a modification, the flue gas cooler 12 is supplied with feedwater from a point within the heater 5 so that part of the heater 5 is in series with it and the remainder is in parallel with it.

Title: Treatment of water vapor generated in concentrating an aqueous urea solution
IPC: C07C273/04
Filed: 1975-12-31
Abstract: A process for treating water vapor generated in concentrating an aqueous urea solution wherein a urea synthesis effluent containing urea, unreacted ammonium carbamate and water from a urea synthesis zone is subjected to a plurality of decomposition stages, the pressures of which stages are stepwise reduced to decompose and separate substantially all of the unreacted ammonium carbamate from the aqueous urea solution. The aqueous urea solution which still contains small amounts of ammonia and carbon dioxide is concentrated to obtain crystalline urea or molten urea substantially free of water. The water vapor generated in concentrating said aqueous urea solution which contains small amounts of ammonia and carbon dioxide is cooled for condensation thereby forming a dilute aqueous ammonium carbamate solution which is subjected to rectification under a gauge pressure below 25 kg/cm2 to distil off a gaseous mixture of water vapor, ammonia and carbon dioxide, introducing the gaseous mixture into the unreacted ammonium carbamate decomposition stage using rectification under substantially the same pressure as the pressure of the rectification for the dilute aqueous ammonium carbamate solution to remove the water vapor from the gaseous mixture, and recovering the resultant ammonia and carbon dioxide together with a gaseous mixture of ammonia and carbon dioxide which is generated in the unreacted ammonium carbamate decomposition stage.
Patent ES-445051-A1 (ES)
Title: Flexible coupling and torque-transmitting member therefor
IPC: F16D3/62
Filed: 1976-02-10
Abstract: A flexible coupling includes a plurality of flexible torque-transmitting members arranged in a circular pattern around the axis of the coupling. Each member is of an elastomeric material and has two parallel stud-receiving passageways. The studs projecting through the radially outer passageways of the torque-transmitting members are supported on their axially outer ends by one part of the coupling. The studs projecting through the radially inner passageways are supported at their axially outer ends by the other part of the coupling. Thus torques are transmitted from one part of the coupling by way of the radially outer studs, the torque-transmitting members, and the radially inner studs, to the other part of the coupling, or vice versa. The torque-transmitting members have a number of features tending to increase the life of the coupling and to preclude relative movements, in particular pivotal movements, of the supporting studs of the torque-transmitting members relative to the torque-transmitting members proper. Each of the torque-transmitting members includes a woven reinforcement strip of which one end is arranged immediately adjacent to one of the stud-receiving passageways of the particular torque-transmitting member. Said strip forms a plurality of substantially spirally shaped windings extending around said pair of stud-receiving passageways.
