Definitions
- the invention relates to a method for using biomass for high-temperature processes, which was previously hardly possible by the fuel-related chlorides in the flue gas and the associated corrosion problems.
- Such a solution is needed primarily in the energy industry for open and closed gas turbine processes, for steam power work processes and in process engineering.
- Biomass direct-fired gas turbine proposed, leading to the mixing of
- the flue gas outlet temperature must be high enough to the fresh air eg.
- the flue gas cools down to about 200 ° C, after which it preheats the biomass by direct contact and dried after the Denox stage in a dryer (eg rotary kiln dryer).
- the moist flue gases can be used as needed for heating purposes, as a heat sink for a heat pump or to be used for feedwater preheating before they flow into the atmosphere.
- an optional shredder for a uniform chip size is required. Feed screws feed dryer and combustion chamber.
- the fresh air fan provides the required combustion air pressure to overcome the flow resistance of each stage.
- biomass can also be used for high-temperature processes, as sacrificial metal surfaces chemically bind the flue gas chlorides in an upstream corrosion filter. Compared to the expense of heat exchanger replacement of the sacrificial metal surfaces is low.
- high-temperature alloys such as Nicrofer 6025 HT or ceramic silicon carbide plate heat exchangers
- working fluid temperatures of more than 1000 ° C can be achieved.
- the flue gas side critical temperature ranges below 600 ° C are used for air and fuel preheating or drying, with hardly any contact with metallic materials are required.
- the problem is solved to operate by means of biomass high-temperature processes and to prevent chlorine corrosion.
- the increased temperature difference between flue gas and working fluid causes a reduction of the required heating surface, which reduces the overall effort with good efficiency. All flue gas pipes (11) are lined from inside, insulated and thus protected.
- FIG. 1 illustrates the shift of the combustion temperature from approximately 900 ° C. to over 1400 ° C. by the measures of strong air preheating up to approximately 600 ° C. and biomass heating and drying up to approximately 200 ° C.
- FIG. 2 shows the method of using biomass for high temperature processes in the Denox stage application.
- optional comminution (5) of the biomass follows Charging the Brömstoffvor Anlagenrs and dryer (7) for forwarding by means of screw conveyors (6) to the combustion chamber (8), in which the processed biomass with strongly preheated fresh air at about 1400 ° C burns.
- the resulting flue gas stream passes through a cyclone for ash cinder deposition (9), wherein the liquid ash particles are separated and discharged by means of centrifugal and gravitational force.
- the flue gas flows through sacrificial metal surfaces in the replacement module (13) in order to chemically bind the corrosive constituents in a targeted manner and to intercept further smaller ash particles.
- the heat exchanger working fluid (14) follows the flue gas cooling to heat the respective working fluid depending on the main process, whether gas turbine or steam power process, overheat or evaporate.
- the still high residual heat content at outlet temperatures of about 600 ° C is regenerated by the fresh air in the air preheater (15), by the biomass pretreatment in Brennstoffvorebenr and dryer (7) and optionally by the heat extraction or feedwater in the flue gas cooling (20).
- the removal of the nitrogen oxides from the flue gas takes over a known prior art Denox stage (19).
- FIG. 3 shows the method for using biomass for high-temperature processes in the application with flue gas recirculation for nitrogen oxide reduction.
- the process is analogous to that of FIG. 2, but there is no Denox stage between the air preheater (15) and the fuel preheater and dryer (7).
- the resulting during combustion nitrogen oxides are reduced by recirculation of the flue gases, since the repeated residence time in the high temperature region reduces nitric oxide formation statistically.
- the combustion air conveyed and compressed by the fresh ventilator (17) passes after the air preheater (15) through the fresh air line (18) to the injector (23), which generates a partial smoke gas flow via the admixing line (22) after the heat exchanger sucks working fluid (14) and this leads back to the combustion chamber (8).
- the emission limits can be met with moderate effort, especially in smaller power ranges.

- FIG. 2 Block diagram of the method for using biomass for high-temperature processes in the application with a Denox stage
- FIG. 3 block diagram of the method for the use of biomass for high-temperature processes in the application with flue gas recirculation
