Demonstration plant WST in Ronneby
Ronneby Miljö & Teknik AB is a municipal company that is wholly owned by the municipality of Ronneby. Their goal is to combine environmental responsibility with economic efficiency. They are currently preparing the installation of a Wet Steam Turbine for electricity production on the existing district heating plant.
Sörbyverket
Ronneby Miljö & Teknik AB is a municipally owned company, which is wholly-owned by the municipality of Ronneby. They manage power, heat, water, sewage, garbage collection, fiber optic networks and broadband. Sörbyverket, the regional district heating plant, is operated by the subsidiary company, Ronneby Miljöteknik Energi AB.
By connecting a turbine to the existing district heating plant, Sörbyverket, Ronneby Miljö & Teknik can produce renewable electricity as well as heat. The development is in line with strategic plan of the company.
Ronneby Miljö & Teknik have chosen to install a wet steam turbine since the boiler of Sörbyverket has the opportunity of steam production. The existing system in Ronneby has been adapted to enable a connection of a wet steam turbine (WST).
The modifications made are mainly modification of the boiler circulation and existing steam dome. Safety equipment, dryout protection, etc. has been supplemented and upgraded. In addition, the boiler has been supplemented with feed water system consisting of feed water, feed water pump and safety valves.
All of the green electricity generated at Sörbyverket will be sold and distributed on the power grid. As a grid company, Ronneby Miljö & Teknik may not produce electricity, but the solution is solved by putting the electricity production in a subsidiary, Ronneby Miljöteknik Energi AB.
The WST will open for study visits in March 2017.
WST
A Wet Steam Turbine (WST) is relatively easy to implement - the upgrade takes place in the boiler water circuit without extensive reconstruction of the boiler. Compared to conventional steam turbines, WST can operate at lower pressure and lower temperature.
WST is a more robust and a less high-efficiency turbine and which
unlike conventional turbines, even can handle some water particles.
