Power Plant
Wärtsilä's versatile power plants make the production of electricity more reliable by adapting to any possible situation related to fuel supply or affordability.
They can even switch fuels while running, for example switching to liquid fuel mode if the gas supply suddenly interrupts. This capability provides 24/7 security supply, fuel price increases and preparation for future fuel infrastructure development.
Wärtsilä's versatile power plants can be run in the following operating modes, and switch between them seamlessly without disrupting the power supply:
Only gas (with liquid pilot fuel): Natural gas, LNG, biogas, associated gases (GD only). Sensitive to liquid gas quality fuel only: crude oil, diesel oil, residual oil, oil-water emulsion, liquid biofuel
Fuel sharing mode (in GD plant): At the same time gas fuel and liquid fuel. Convert the fuel without power loss, automatically and immediately trip to liquid fuel mode in alarm situations
Gas and multi-fuel tree power
Wärtsilä provides modern generation solutions for basic, intermediate, peaking and standby applications. Wärtsilä's gas-powered and versatile power plants are often based on 4-19 MW (ICE) internal combustion engine units. ICE can be used either in natural gas or in multi-fuel mode using both gaseous and liquid fuels.
Wärtsilä's multi-fuel and fuel-efficient power plants provide high reliability and efficiency; Even if the conditions are the most challenging. Their energy output and fuel efficiency are still consistent across the load, whether operating in hot deserts, mountains, downtown or dense jungle heat. Negligible amount of water is needed to be worthless in dry places. Flexibility in the unique operation of ICE technology with super-fast start and stop and ensure fast loading of continuous control of load fluctuations. As demand grows, modular design makes it easy to expand power plants to meet future needs. Trees can be upgraded at any time without risking their reliability. Such increased investment also ensures continued competitiveness in the volatile market today. Moreover, some small units are always more reliable than one large unit.
Our power plants are backed by world-wide operations
and management services ensure effective and optimal performance of equipment throughout its life cycle. We provide real flexibility, both in terms of fuel options and in the ability to meet operational needs. This makes Wärtsilä gas and many power plants a solid choice in the electricity market today.
Wärtsilä is designed for optimum performance in many distributed manufacturing applications: basic capacity, peak power and CHP plant. The plant can be located in the middle of a densely populated area, or in a remote location with minimum infrastructure resources.
Modular design simplifies plant configuration to meet specific customer needs. Adding features is a matter of adding modules, which are pre-tested for compatibility and reliability. Built-in, integrated solutions help to streamline planning and delivery processes, generating additional savings and earnings.
A typical Wärtsilä lot or batch of generators includes:
Generator. Mechanical auxiliary system including fuel system, lubrication, air intake, cooling, exhaust gas treatment and sound insulation.
Electric systems. Automation
Heat recovery system in CHP plant
Civil works and works.
Optional Wärtsilä Flexicycle includes an additional boiler module for controlling a steam turbine, supplied by waste heat from the engine. This combined cycle solution increases power output by almost 10%.
Steam cycle options can be included in the initial design, or added at a later stage. In CHP applications for hot water production, total efficiency can reach 95%. This reduces the cost of electricity generation and increases the economic attractiveness of these plants.
The environmental impact of Wärtsilä or low-power stations is low. NOx emission levels are low enough to meet most of the current environmental regulations without the need for secondary cleaning. To minimize environmental impacts and comply with the most stringent regulations, it is possible to install efficient oxidation catalysts, NOX catalysts and other advanced equipment.
Engine cooling using a closed-loop heatsink reduces the amount of water consumed by the process to only 0.2 liters / MWh, minimizing the impact on local water.
The design of the engine room and low profile construction helps the plant mix with its surroundings. An efficient sound system allows the plant to operate even in densely populated areas, near actual loads, effectively preventing transmission and distribution congestion.
High power efficiency
Minimum power consumption of the plant
Simple and reliable technical solution
Compact factory design, front design
Optimized for distributing EPCs to remote areas with limited infrastructure. The Wärtsilä, GasCube and OilCube energy blocks, are pre-designed, single-energy power plants. They are manufactured in a cost-effective framework to justify turnkey deliveries to small factories while meeting the needs of different customers and applications. A Wärtsilä GasCube consists of several engine modules designed to meet the total power demand of 6-30 MW. A Wärtsilä GasCube is based on the Wärtsilä 16V34SG or Wärtsilä 20V34SG, with all the auxiliary equipment and components required, providing 7-10 MWe per unit. Wärtsilä 34SG can operate in a window of 10-100% load. Due to the closed design, GasCube is the optimal solution for fast and cost effective project implementation.
Wärtsilä internal combustion engines operate on a variety of gases. They can use both natural and liquid fuels (light fuel oil, heavy fuel oil, crude oil or liquid biofuels). When the supply of gas is uncertain, or the price fluctuates, it can switch from gas to liquid fuel, and vice versa, even during operation. Optional to run on liquid fuel as a backup that significantly improves reliability.
In emerging gas markets, it is possible to build a fast-paced factory, initially operating with liquid fuel and being converted to gas-operated and when. This also works in another way: Existing power plants with gas conversion capabilities provide a good basis for investments in gas infrastructure. Wärtsilä gas engine with state-of-the-art lean burn technology achieves over 50% efficiency. Heat recovery options do not affect the generator's electrical performance. High efficiency translates into significant savings in fuel costs compared to other technologies.
Multiple unit configurations create a partial load configuration that maximizes the plant's output range. For any given load, as many on-demand generators are operated at optimum efficiency.
The Wärtsilä gas-fueled and versatile power plant is subject to extreme conditions, with low temperature rates and high altitude output and under hot conditions. In addition, Wärtsilä power plants can be located anywhere because they run on low pressure, and the water consumption of their air cooling system is negligible.
The concept of creating multiple sets guarantees high reliability and usability. All maintenance can be done in-place, once per engine, leaving the remaining units fully available for the task. The use of some of the same motors also reduces the cost of the stock on the spare parts website.
The KivuWatt power plant in Rwanda uses natural methane gas from the Kivu reservoir to generate electricity through the Wärtsilä 34SG. The adjustability offered by the advanced control system of the Wärtsilä 34SG engine allows the use of pipes and gases associated with a wide range of gas components.
Engine generators used in Wärtsilä thermal power plants are driven by four-stroke internal combustion engines. These high-power generators include a motor that is directly connected to the transmitter via a flexible coupler. Generators and motors are mounted on a common base frame.
Engines burned (SG)
The Wärtsilä SG is a combustion engine. In this process, the gas is mixed with air before the valve inlet. During the charging phase, the gas is also placed in a small chamber, where the gas mixture is very rich compared to the gas in the tank. At the end of the compression stage, the gas-air mixture in front of the chamber is ignited by a spark plug. The flame from the nozzle of the pre-combustion chamber is mixed in the entire cylinder. Fast burning. After the cylinder work stage is emptied of the exhaust gas and the process starts again.
Double Fuel Engine (DF)
When operated by gas, the dual fuel engine uses a lean combustion process. The air is mixed with air before the valve enters the intake air. After the compression stage, the air mixture and the gas are burned by a loose liquid fuel. After the work period, the exhaust valve is opened and the cylinder is emptied of exhaust gas. The inlet valve is opened when the exhaust valve is closed, and the process starts again. The dual fuel engine is also equipped with a backup system
fuel system. This is a normal diesel process with liquid fuel pumps running on camshaft, running in parallel with the process and working as a stand-by. The engine can switch between diesel and gas modes, even during operation.
Gasoline Diesel Engines (GD)
The Wärtsilä GD engine uses diesel oil combustion in all operating modes. In gas mode, the gas is injected into high pressure after the pilot fuel and is burned by the next flame. Pilot fuel is equivalent to about 5% of total fuel input.
Gasoline-diesel engines can be switched instantly from gas to liquid fuel. Liquid fuels can be light fuel oil, heavy fuel oil or crude oil. In this case, the process is like the normal diesel process.
In fuel sharing mode, the ratio between liquid fuel and gas can be controlled and changed during operation. Operating windows for the fuel-sharing mode are 30-100% of the load, and the gas / liquid fuel ratio may vary according to the fuel-sharing window. This process can withstand large variations in gas quality and is especially suitable for low quality, such as gas bonding in oil fields.
