Abstract:
Desde a revolução industrial, uma das maiores preocupações dentro de uma indústria é evitar paradas indesejadas de seus equipamentos. Por décadas, a manutenção vem se especializando em métodos e meios para que a produção seja plena, sem contratempos. Nesse sentido, essa pesquisa tem por finalidade apresentar a importância da lubrificação industrial em turbinas a vapor, o uso correto de lubrificantes e como é feito seu descarte. Um bom plano de lubrificação dará a plenitude da vida útil de peças e equipamentos. Esse artigo teve como objetivo analisar os métodos de lubrificação em uma destilaria

La modernización de procesos industriales es vital para mantener el giro de negocio de la manufactura. La mayoría de turbinas de vapor fueron creadas hace más de 30 años en la escala temporal, muchas de ellas indispensables para la generación de electricidad. Las Turbinas de vapor pueden entregar de manera fiable y eficiente inclusive de 100 a 200 MW al sistema nacional interconectado. La tecnología que acopla una turbina y sus sistemas auxiliares a un generador, se sigue desarrollando y es utilizada a gran escala a nivel mundial.

INTRODUCTIONFlow and volume measurement of incompressible fluids are prevalent in many engineering processes. Flows in a pipe network, also called pipe flow, are widely encountered in industry and our daily activities. For example, water is delivered to homes via the pipelines of a water distribution infrastructure. In power plants, numerous pipe flows are used to transport liquid, vapor, and two-phase flows: steam produced in boilers is transported in pipes to steam turbines for energy conversion. Boiler feed water (BFW) is pumped to a boiler via a BFW pipe.

The Rankine closed cycle is a process in which beat is used to evaporate a fluid at constant pressure in a “boiler” or evaporator, from which the vapor enters a piston engine or turbine and expands doing work. The vapor exhaust then enters a vessel where heat is transferred from the vapor to a cooling fluid, causing the vapor to condense to a liquid, which is pumped back to the evaporator to complete the cycle.

Abstract:
Studies have been conducted to develop a fixed granular-bed sorber for the removal of alkali vapors in a pressurized fluidized-bed combustion (PFBC) combined-cycle system. A laboratory-scale pressurized alkali-vapor sorption test unit was used to characterize activated bauxite, the most effective sorbent identified earlier, for its alkali vapor sorption capability in a gas stream with temperature (≤900°C), pressure (10 atm absolute), and composition closely simulating the actual PFBC flue gas. A scale-up of laboratory tests is being conducted in a 15.2-cm-dia (6-in.-dia) PFBC system to demonst

Gas turbine blades have previously been shown to corrode due to condensation of sulfide vapor on a cooled blade surface. In the present investigation, water vapor was condensed on a film cooled surface, simulating the condensation of sulfide vapor on a turbine blade. The injection section consisted of one row of holes (inner diameter of 1.0 cm) inclined 30 degrees with the surface and inline with the main turbulent boundary layer flow. Experiments were carried out in a subsonic, zero pressure gradient, turbulent boundary layer with free stream velocities of 10.5, 15.75, and 21.0 m/sec. A cooli

Abstract A validated finite element model of air flow in the human nose was used to simulate nasal uptake of inhaled vapors. Computed steady laminar velocity fields were used in the solution of the uncoupled steady convective-diffusion equation. A wall boundary condition was developed that included effects of vapor solubility, transport, and removal in the nasal mucosa. The maximum inspiratory uptake was about 80% for highly mucus soluble vapors with Schmidt number equal to one at a half-nasal flow rate of 125 ml/s. The maximum flux in the turbinate region occurred at the anterior-inferior end

Abstract:
As electrical energy consumption has continued to rise in the United States, and producers of electricity search for power plants requiring less installation time, the gas turbine has emerged as a significant contributor to our nation’s energy needs. Despite a thermal efficiency disadvantage as compared to a conventional steam power plant, it has nevertheless played an increasingly larger role in the production of electrical power. A scheme is here presented whereby the output of a given gas turbine can be increased by more than 60% and its efficiency increased by 30%, thus making it more comp

Abstract:
Mechanistic models have been developed for particle and vapor deposition on the blades of coal-fired gas turbines. The particle deposition models include the simultaneous contribution of Brownian and turbulent diffusion, thermophoresis, eddy impaction, and inertial impingement. The diffusive mechanisms have been validated against experimental data for low-speed cascade flow and particle-laden flow through pipes. The inertial deposition treatment is shown to collapse to the well-known expression for particle capture in a flow turning around a bend. A method is presented for calculating Na2SO4 a

Abstract:
Vapor compression refrigeration plant power consumption can be heavily reduced for a definite cooling power by the adoption of a power regeneration process internal to the simple cycle. Such a process takes benefit from the adoption of turbomachinery based vapor pressure amplifier. The selection of the wheel sizes, their machining to be adapted to the process and the addition of stator blades in the expander and a diffuser in the compressor path is discussed and tests results are presented. Improvements of the power consumption and of the COP of about 23–24% for a specified cooling power have

Abstract:
Originally developed mainly for solar energy utilization, the Ormat Closed Cycle Vapor Turbines were first applied to fossil-fuel on-site power generation in remote locations because of their inherent high reliability and low maintenance characteristics. Latterly, conditions changed and the technology has been reapplied to its original use: e.g. solar ponds, waste heat recovery and moderate temperature geothermal sources. This paper presents the results of actual field experience of operating some 3,500 turbogenerators in various applications.

Abstract:
Vapor Phase Lubrication (VPL) is an emerging technology that is currently targeted for application in limited life, expendable engines. It has the potential to cut 90% of the cost and weight of the lubrication system, when compared to a conventional liquid lubricated system. VPL is effective at much higher temperatures than conventional liquid lubrication (600°C vs. 200°C), so considerably less cooling for the bearing is required, to the extent that the bearing materials often dictate the maximum upper temperature for its use. The hot #8 bearing and the cold #1 bearing of the T63 engine were u
