Rolls-Royce
Currently "NG-Energo" company is implementing on the territory of Russia the projects of capital construction for oil and gas industry together with Rolls-Royce company.
Rolls-Royce generator sets
Rolls-Royce gas generator units work on natural gas, associated gas and biogas. The standard methane number, which does not require any improvements, is 70 and more. Fuel gas caloricity starts from 18 MJ. Engines are characterized by efficiency, reliability and durability, while having a simple design and low operation cost, as well as a high electric efficiency factor of the generator - 46.4%. To make the operation more convenient and less expensive, the engines of «К» and «В» series with the capacity of 2.2 - 8.5 MW can be reequipped, without transporting them to the manufacturer's plant, for various types of fuel: gas - diesel - fuel oil. Technical readiness of the equipment is not lower than 0.98. For working on associated gas, Rolls-Royce uses the authentic patented technology of methane number increasing right in the working prechambers by means of controlled admixture of exhaust gases. Rolls-Royce power stations are created for extremely severe operating conditions from the equator to the Arctic and ambient temperatures ranging from +50 to -60?C.
Rolls-Royce power plants operation system
All the elements of a generator set are very simple and reliable. The system of operating generator sets and the entire power plant consisting of several gas piston units is divided into three modes: Every technological unit can be operated manually, semi-automatically, and automatically. The generator set operation system contains independent control cabinets for every generator set and an integrated control panel. That is why Rolls-Royce generator sets are recognized around the world as the most reliable, and they are ordered few years in advance by countries with the lowest educational level, as it is practically impossible to disable Rolls-Royce sets. Disconnection or failure of one or more combustion chambers does not cause the generator set shutdown due to an authentic system of separate treatment and distribution of the fuel mixture for every chamber and automatic redistribution of their fuel supply to the chambers remaining active in order to conserve a rotational moment.
Air systems
The system of air supply for combustion contains air compressors with changeable geometry, which allows taking the load by generator sets from the idle to 50% of the nominal capacity without losing the specified quality of electric power. The options of building a gas exhaust system have the equipment for carbon dioxide emission, and therefore Rolls-Royce gas piston units are used as the basis for the creation of modern hothouse factories for all day and all year round growth of vegetables, flowers, etc. And their ability to work on depleted biogas from hothouse wastes processing makes the products inexpensive and consequently highly competitive.
Advantages of Rolls-Royce gas piston generators
- Long service life - 100000 machine hours before the first overhaul, total life up to 50 years;
- High maintainability - all kinds of maintenance at the place of operation;
- High electric efficiency factor - 46.4%;
- Low speed of crankshaft rotation - 750 rotations;
- Low level of vibration and noise compared to the generators with 1500 rotations;
- Low fuel consumption: 0.24 nm3 to produce 1 kW;
- Low temperature exhaust gases - compliance with tough environmental requirements - standard 250 without a catalyst;
- Modular design of a generator set and auxiliary systems allows fitting the weight and dimensions into any conditions and transport type;
- Modular design allows erecting power plants in northern conditions on the basis of Rolls-Royce generators in most tight schedules.
Application
- Electric power and heat source for housing and utilities infrastructure with the proved total efficiency factor (electric power + heat) of 90%. Electric power and heat source for production facilities where the highest level of guaranteed power supply is required in hard operating conditions (examples: glass-making, continuous steel casting, petrochemical industry, cement producing, etc.);
- Backup power supply source for strategic pipelines (oil and gas pipelines);
- Associated gas power supply source on drilling platforms and remote fields.
