Objective
* energy saving by cascade elements
* changing the inferior thermal energy for the superior supply medium 'cold'
* substitution of current by low-temperature heat in refrigeration
* reduction of the pollutants NOx, CO, S02, C02 etc. by a reduced consumption of primary energy
* elimination of the contaminant CFCL%
* The stages of official authorisation have ended to a large extent.
* The essential project plannings have been worked out and the specifications
have been issued.
* The orders for the main components and the various plant systems have been
placed with the respective manufacturers.
* Several of the large plant elements have already been delivered to the site
and are mounted/assembled at present.
* By appropriate measures taken to accelerate the assembly and mounting,
the individual sections of the plant are erected expeditiously.
* Any and all activities in this context are co-ordinated by
a project management.
The filed project with its innovative system engineering will be installed and continuously operated in our plant, integrated in a modern combined power station with gas and steam turbine process.
The purpose and the essential advantages of the modified system technology are:
* the thermal energy saving by cascade elements
* the multistage improvement of the low thermal energy to the superior supply medium 'cold' (transformation effect),
* the substitution of current for the electro-mechanical refrigeration plants by the low-temperature heat in process refrigeration
* the reduction of the pollutants NOX, CO, CO2, SO2 etc. by a lower consumption of primary energy
* the elimination of the environmentally hazardous CFC substances.
On account of a multi-stage heat transformation, the new plant configuration allows to bring back the used and returned heating water to an effective temperature level of max. 130? C.
Through three different temperature stages, the temperature of the circulating water first of all is increased in the system to a flow temperature of tv3 = 95?C.
For this purpose, the flow temperature level is increased to tvl = 65?C using the external waste heat (oil cooling etc.) generated by recooling the various section components like e.g. gas turbines and steam turbine.
Any further temperature increases by residual heat are made by two coupled and precisely specified exhaust steam floating channels with load-dependent evacuation equipments. These cascade stages 2 and 3 are arranged downstream of the steam turbine and increase the flow temperature to tv3 = 95?C. In the last stage, the circulating water is heated to the usable final temperature of tv < 130?C using the serially connected exhaust-gas residual heat exchangers. The modular exhaust-gas residual heat exchangers arranged downstream in the exhaust-heat boilers are installed on the so-called 'cold' side of the boiler.
Via a controlled pump station the generated effective heat is delivered to the next energy cascade. First of all, the thermal energy is utilized by the two-stage process refrigeration. The process refrigeration is effected by absorber machines connected in series and controlled as a function of the temperature. The absorber equipment operates without any CFC and also without ammonia.
Downstream of the absorbers a usable temperature level of tR2 = 85?C is still available. This heating water coming from the absorber machines is subsequently fed to the extensive heating system for a further utilisation of energy. The temperature is decreased hereby to tR3 = 60?C. The energetic loop of the innovative system technology is closed hereby. It is only by this multi-stage system technology and the necessary cascade elements that the four-stage improvement and the three-stage utilisation is possible.
Of course, the plant system is utilized automatically and continuously by a computer-aided control system.
