Duplex lubricating oil filters and oil coolers
Dc motor driven emergency oil pump
Integral lubricating oil dehydration system
Lubricating oil mist elimination system
Back pressure turbines can either be single stage or multi-stage which are often used in industrial plants, the turbine serves as a reducing station between boiler and the process steam header.
These turbines can either be used for drive application (sugar mill drives, sugar fibrizor / shredder drive, pump drives and so on) or power generation application in which case the turbine drives the generator. These turbines are straight-back pressure type and find application where back pressure steam is fully utilized to meet process demands. The power generation is incidental to the process steam demand.
The back pressure turbine may also have bleed points (uncontrolled extractions) to satisfy steam demands at intermediate pressures, this provision is applicable when the bleed (medium pressure) steam volume demand is low and pressure variations can be tolerated. These turbines are of bleed cum back pressure type.
The extraction condensing turbines are used when a constant pressure steam flow has to be extracted for process purposes. The constructional characteristics of these turbines are very similar to condensing turbines from the second admission valve chest it is possible to inject low pressure steam, available in the plant to supply the power required by the plant.
These turbines are typically used for co-generation where the turbine meets both the power and steam demand of the process plant. In these type of turbines the power generated can be maintained more or less at a steady level despite
The condensing turbines take high pressure steam, expand it in turbine nozzles and blades, and exhaust it to a condenser at lower than atmospheric pressure. It is principally used when power must be generated with minimum steam consumption. The condensing turbine may also have bleed points (uncontrolled extractions) to satisfy steam e.
These type of turbines find application mainly for power generation where bleed steam is required for feed water heating (hp heater, lp heater and deaerator requirement) and / or where bleed steam is utilized to meet small process demands.
Feed pump turbine drive packages are available from 100kw – 20mw. Complete steam turbine boiler feed pump packages are available, in addition to stand-alone steam turbine packages.
7 models, horizontal (axial and radial split), vertical , api 611- and 612-compliant, overhung and between-the-bearings wheel designs, metallic or carbon seals, electronic / hydraulic mechanical governors, customized steam path components, mechanical / electronic safety trip system, direct-drive or integral gear boxes with suitable lubrication systems.
