Übersetzung für "Exhaust residue" in Deutsch

Environmental dirt, fuel stains from overfilling, insects, bird droppings and exhaust residue are reliably removed thanks to its excellent ability to penetrate dirt.

Preferably, the feed device can be sealed off in a gas-tight manner by means of a check valve from gases, dirt, moisture, solid exhaust residue, etc., which can penetrate into it via the tube from the ammonia generator or the exhaust line. BRIEF DESCRIPTION OF THE DRAWINGS

After combustion bottom ash, hot exhaust gas and residues remain.

When it is mounted on the exhaust supply side, the danger of deposits composed of exhaust residues is much less.

To ensure a constant volume flow necessary for circulating the exhaust air, fresh air is subsequently fed into the remaining residual exhaust air flow, and the amount of fresh air essentially corresponds to the amount of exhaust air discharged before.

The amount of exhaust air, which thus consists of the residual exhaust air flow and the fresh air fed in, is finally returned into the DTC plant at a point separate from the point of removal.

This danger, which is even greater when the valve is located downstream from the exhaust cooler, means that adjusting elements with relatively high adjusting forces must be provided which can reliably overcome any jamming of the valve elements caused by deposits of exhaust residues.

Such an overrun of the pump 19 after the internal combustion engine ICE has been switched off provides an air cushion at the tip 143 of the injection valve and at the end (jet outlet side) of the injection valve 14 facing the exhaust gas, this air cushion preventing the exhaust heat (residual heat) of the exhaust-gas after-treatment system heating up the injection valve 14 and the reducing agent.

As a result of the oxygen surplus in the exhaust during lean operation, however, the three-way catalyst can no longer maintain its function of reducing the oxides of nitrogen contained in the exhaust by residual hydrocarbons.

A process according to claim 2 wherein after the pyrolysis residue capacity for physical adsorption is exhausted the pyrolysis residue, which has heavy metals and complex silicate, is mixed with calcic compounds, then pressed to form dimensionally stable pellets and is subsequently calcined at at least roughly 1200° C. or above during which the heavy metals are incorporated in the structure of the complex silicates.

A process according to claim 2, wherein after its capacity for physical adsorption is exhausted, the pyrolysis residue is ground to dust and mixed with a substance selected from the group consisting of acids, acid mixtures, solvents, and solubilizers so that a substantial part of the metals, metal compounds and alloys combined with the pyrolysis residue go into solution and can be supplied for reutilization.

Moreover, exhaust gas residues can be entrained in the leakage stream which extends beneath the radial seal between the different gas areas, which exhaust gas residues can attack the surfaces of the radial seals, thus further reducing the tightness of the radial seal strips.

By this method, it was anticipated that the waste waters, exhaust gases and residues produced hitherto would either be avoided, reincorporated into the production cycle or suitable for ecologically harmless disposal.

As general contractor, Dürr EES delivered an Ecopure ® VAR oxidizer consisting of five process modules: a supply system for the different exhaust gases and residual liquids that complies with all safety requirements, a combustion chamber, an SNCR unit (selective non-catalytic reduction) for reduction of nitrogen oxide emissions, a waste heat steam boiler and a scrubber system for the removal of inorganic halogen and sulfur compounds from flue gas.
