The GKS Gemeinschaftskraftwerk Schweinfurt GmbH operated by GKS Gemeinschaftskraftwerk Schweinfurt is a coal-fired power plant with an attached waste incineration plant . It is located in Schweinfurt . It supplies various large local companies and large parts of the city's residential areas with district heating . It is also the largest power generator within the city.
Company portrait
The GKS Gemeinschaftskraftwerk Schweinfurt GmbH was founded to provide the local shareholders with heating. The construction of a coal-fired power station, in which district heating was to be provided by means of combined heat and power (CHP), was realized in 1990. The waste incineration plant was put into operation in 1994. Important shareholders and heat consumers are:
- FAG Kugelfischer (2006 part of the Schaeffler Group )
- SKF
- Stadtwerke Schweinfurt
- ZF Friedrichshafen , Schweinfurt site
Description of the technology
The coal-fired power station consists of two steam boilers, each with a thermal output of 63 MW. The annual demand for hard coal continued to decline from the original 45,000 t to just 28,180 t in 2018. In 2018, hard coal was purchased in Poland (22,000 t), Colombia (5,000 t) and Russia (1,400 t). The exhaust gases from the coal combustion run through a flue gas desulphurisation system and a fabric filter. The coal bunker upstream of the plant has a capacity of 300 t. The coal is delivered by ship and rail.
A thermal waste treatment plant with three furnace lines was integrated into the combined heat and power plant. Each furnace has a thermal output of 18.9 MW and is designed for a waste throughput of 8 t / h. The residual waste generated in the Main-Rhön region has been disposed of since 1994 .
155,000 tons of waste are incinerated every year. In addition to 5,300 t flue gas cleaning products, 41,540 t slag as well as 42.7 GWh electricity and 232 GWh district heating are produced. The firing is designed as a moving grate, the firing operation takes place in countercurrent. For flue gas cleaning, the exhaust gas from the waste incineration passes through the following components:
The waste ( household waste , bulky waste , commercial waste) is only delivered by truck. The garbage bunker has a maximum capacity of 7,000 t.
The flue gases from the combustion processes are discharged through a 97.5 m high chimney.
The grid connection takes place at the 110 kV high voltage level in the power grid of the distribution network operator E.ON Netz .
From 2020 sewage sludge will be incinerated in the GKS in an in-house development. 9,000 tons a year are to replace 3,000 tons of coal. The aim is to reduce immissions , especially carbon dioxide . The sewage sludge is blown onto the grates of the coal section, where temperatures can reach 1,400 degrees.
In 2018, the garbage section produced 493,700 megawatt hours more output than in any other year since it was commissioned.
Waste incineration catchment area
The catchment area of the waste incineration plant includes the independent cities of Aschaffenburg , Kaufbeuren and Schweinfurt as well as the districts of Aschaffenburg , Haßberge , Main-Spessart , Main-Tauber , Miltenberg , Rhön-Grabfeld and Schweinfurt .
