Containerized, plug&play power plant - Sittingbourne, UK
Asoto delivered and commissioned three containerized power modules custom-built by the client's specifications. The purpose of the modular power plant in Sittingbourne is to balance the local electricity network and ensure the grid's resilience. All three power modules facilitate Jenbacher 6th series J620 engines capable of producing 2.7MW electricity.
The power modules are fueled with natural gas and built for electrical energy production. The heat produced as a byproduct in the process of electricity generation in this application is not being utilized. Thus, all of it has to be dumped via dry coolers mounted on the roof of the containers.
The plug&ply power modules come in transportable and spacious steel containers with a service-friendly design for hassle-free maintenance and operations. The containers are divided into two rooms: the machine room and the control room. The machine room accommodates the genset and all necessary auxiliaries, while the control room houses safety and control systems.
The container floor is made of a chequer plate and constructed in a way that it can serve as an oil leakage sump. For optimal noise isolation, the inside of the containers is lined with mineral wool, an insulation membrane, and perforated metal plating for longevity.
The dimensions for the containerized power plant, with exhaust and cooling systems mounted, are 17,230 x 5,225* x 6,602* This is because the highest point of the exhaust pipe end is 6,602*mm.
Asoto built these containerized power modules to operate at an ambient temperature from -10oC to+30oC, and the minimum noise requirement being 65dB(A)at 10m.
The Layout:
External:
Exhaust Gas Silencer
A free-standing silencer with integrated catalytic converter elements. The engine’s frequency band, the required target levels, and the possible pressure drop are considered to reduce sound emissions.
Dry Cooler
Specification designed V-shape Dry Cooler to meet the engine requirements, ambient temperature, and noise restrictions.
Access ladder to roof and railing
Steel ladder and railings to provide access and safety during maintenance work and checkups of auxiliary equipment.
Gas connection flance
Connection point to the plant's gas line.
Internal:
Generator Set
Jenbacher Type 6 Generator Sets J620, factory overhauled by PowerUP GmbH.
Air inlet silencer
Series of sound-absorbing panels designed to limit the noise generated by the power module and allow an optimal flow of the combustion air in the engine room.
Air outlet silencer
Sound-absorbing panels are positioned to limit the noise generated by the power module and allow steady exhaust airflow..
Air supply fans
Engine room ventilation to ensure the discharging of the radiant heat from the unit and for combustion air supply to the engine.
Engine heating system
The engine heating system warms up the engine and keeps it at a ready-to-start temperature, ensuring faster engine starts and reducing engine wear.
Engine cooling system
The engine cooling system removes excess heat to maintain the engine operating temperature so it can work most efficiently.
Gas train
The gas train supplies the engine with gas and contains regulatory, measurement, and control elements.
Oil tanks
A tank for the storage of lubricating oil is installed in the container.
Control systems and panels
A user-friendly engine management system that provides engine management, monitoring, and control. All error messages are date stamped to identify the sequence of events.
Safety systems and equipment
Smoke alarm system with detectors in the machine and control room and a gas warning device in the machine room. Powder fire extinguisher in the control room
Air temperature control system
Air temperature sensor in the machine room. Heating radiator in the machine room. Electric heating/cooling in the control room as well
