Translation of "Betriebsstillstand" in English

During shutdown, any excess oil is re-absorbed back into the polymer material.

In the case of a large air fractionation plant, this can mean an operational shutdown of, for example, two to five days.

After a total stoppage lasting 38 days, the company saw itself with no option but to reinstate 70 workers.

In this manner, a downtime determined by knife change is limited only to the duration of the swiveling procedure of the knife holder.

This state results in a stoppage of production, which leads to tremendous economic damage.

Shorter turbine installation and servicing times reduce downtime from weeks to only a few days.

This applies, in particular, if, in the event of a plant shutdown, the supply of lean gas (blast furnace waste gas) from the blast furnace also ceases, and only rich gas (natural gas, coke-oven gas) is available for the "stand-by" operation.

Maintenance of such air gap contactors not only causes increased cost but also results in operational shutdown of the switched devices for the period during such maintenance, which may result in even greater expense.

In order to prevent such damage, precautions must be taken, for example by means of emergency generators, so that upon a cessation of operations cold substrate solution may be pumped through the reactor, in order to obtain the necessary rapid cooling of the sensitive catalyst.

Moreover, during shutdown, the system can be backflushed advantageously with water or with a cleansing liquid without allowing the latter to enter the whirlpool bath.

In the interior of the housing 21 there are braking jaws 31 for securing the lance and the clearing device 29, in case of an operational stand-still.

The flow admission tubes have discharge openings (not shown) for the fluidizing medium, which are preferably arranged on the lower sides of the tubes in order to prevent fluidized material from penetrating when not in operation.

This always leads to a long operating stoppage and is linked with considerable accident risks for the workers working in the trough.

Practically all lines or conduits but also the filter cloth were found to have been considerably encrusted with Na2 SiF6 already after two days of operation; the encrustations affected the filtration output considerably and in the end made it necessary for the production to be stopped.

The object of the present invention is therefore to provide a synthesis gas heat exchanger unit, whose self-cleaning from residual particles, dust deposits and other solid particles is improved during the hot operation, during the start-up phase and during shutdown, in which the mass flows in the individual heat exchanger flues are controlled and in which interruptions of operation and increased maintenance costs are avoided.

In the event of leakage of the primary coolant from one or more grate bars, the secondary coolant could enable the continuation of furnace operation until the next scheduled maintenance stoppage.

In the first case there is at least the disadvantage of an increased power requirement in order to overcome the arising friction forces, and what is more, there is a breakdown of operation or a tearing of the filter element.

Furthermore, existing scrubbers can easily be converted to the process of the invention without the necessity of interrupting the operation.

As a result of the clamping holding means a dropping down of the breaking segments and damage caused by the same such as operation shutdown, repairs, etc. are avoided.

At the same time, the novel discharge nozzle permits, during its shutdown, an automatic sealing of its interior against the water of the whirlpool bath which may contain many impurities, which otherwise could lead to the clogging of the feed system.

Moreover, during shutdown, the system can be backflushed advantageously with water or with a cleansing liquid without allowing the latter to enter the whirlpool bath.
