This allows all ranges between low load and full load to be selected.

Such a design is therefore particularly reliable to operate particularly in light-load or start-up mode.

In low-load conditions flow takes place through the heating surface 13 in the flow-bed cooler 7, without heat being transmitted.

A volume load of 2 kg oTs/m 3 per day is considered to be light load.

The quantities sold are between 25000 and 2000000 MWh per type of product (off-peak/base/peak).

The above calculations are based on average price figures, i.e. they do not calculate separately with off peak, base or peak prices.

Since both the ignition gas jets 24 and the flame retention nozzles 28 are fed by the ignition gas chamber, the gas stream for the pilot flame is approximately proportional to the gas stream leaving the ignition gas nozzles 24, with which the turbine can be driven with no load or perhaps with a slight load.

The heating surface needed for full load beyond the needs for low load, is accommodated in the flow-bed cooler 7 as the heating surface 13.

This power generating plant at times of low load, generates methanol to an increased extent and the so-produced methanol can be sold as raw material unless it is needed for equalizing peak loads.

This power generating plant permits increased production of methanol during times of low load and sale of the methanol so produced as a chemical raw material to the extent it is not needed for equalizing peak loads.

The hydrogen and carbon monoxide content of the purified gas fed to these modules at low load can thereby be more completely reacted.

SUMMARY OF THE INVENTION An object of the present invention is to provide a converter device that can be operated with variable frequency in a light load or overload condition and can be operated with a constant operating frequency in a normal operating condition.

In the inventive circuit arrangement, the advantages of a variable-frequency converter in the light load and overload case are combined with the advantages of a constant-frequency converter operated with pulse-width modulation.

When the converter is operated at light load, then the pulse-duty factor ton /T must likewise be greatly reduced since the transmitted power of the system is greater than the power required of the converter as the circuit output.

It has a virtually infinite memory, which means that short-term peak loads fill the virtual memory, so that too quick a decision is made regarding overload during high loads reoccurring much later, if no low load phase has been interposed.

It was already mentioned further above that it is advantageous if the vacuum deaerator 19 is also switched off above a certain low load.

An additional advantage resulting from the low space requirement can be seen in the fact that this switch can also be installed subsequently into already existing filter-circuit arrangements and thus provides an improved filtering action with low load without changing the original filter characteristic when the coupling switch S4 is open.

If the air requirement is beyond this value or the working range of the AERZEN turbo machine, a positive displacement blower of AERZEN type Delta Blower takes over the work at low load, or switches on at peak loads.

However, in start-up operation, under little or no load, it is not possible to increase the mass flow since this would increase the turbine output.

In certain operating states of the internal combustion engine, chiefly in low-load operation, overrun operation, engine braking operation, in idling phases or when turning off the engine, a reversal of the flow direction of the exhaust gas can occur so that reductant, ammonia split off from the reductant, or byproducts formed from the reductant, e.g., isocyanic acid (Equation 9), cyanuric acid (Equation 10), and so on, can come into contact with the parts of the engine in contact with the exhaust gas due to return flows and/or diffusion in direction of the engine block.

In this case, the engine control unit only has to ensure that the exhaust gas purification components 2 do not fall below the required operating temperature in the case of low load or idling.

As has already been stated, in certain operating states of the internal combustion engine, chiefly in low-load operation, overrun operation, engine braking operation, idling phases or when turning off the engine, a reversal of the flow direction of the exhaust gas can occur.

When cold starting the engine or at low load, the engine exhaust gas temperature is frequently so low that, in particular with lean-burn internal combustion engines or with natural gas engines, for sufficient pollutant conversion, an excessively high level of precious metals of the exhaust gas catalytic converters is required which is associated with corresponding costs.

In particular, since the steam turbine is operated at low load during starting and the steam in the outflow region is at a comparatively high temperature, the high-pressure turbine section is subjected to particularly high thermal loading during a hot start.
