DE479032C - Gas generator with top fire for the generation of permanent gases - Google Patents

Description

Gas generator with a top fire to produce stable gases For many For the purposes of combustion technology, it is worth striving for, especially inferior ones Fuels produce a stable gas in order to use this gas for heating stoves to be able to use.

Particular attention is paid to the use of such stable gases intended for heating tunnel ovens, shaft ovens, ring ovens, chamber ovens and the like.

While usually in the gasification of fuels, the clean gas production is associated with de-taring the generator gases, as is well known, the Turn tar fumes into persistent gases.

In such a case, gas cleaning is easier, and it is also included nuisance to the neighborhood and pollution associated with tar extraction the sewage continues.

The production of persistent gases from the fuels mentioned Art is known per se.

The known versions also usually have at the foot of the Gas generator burning fire a second nasty, upper fire.

While these explanations do not ensure that the air can act on the fuel from all sides, is the upper fire after the present invention distributed throughout the gas generator scope.

The present version also has a special smoldering shaft, as it is known per se from such gas generators.

According to the invention, the arrangement of the ring line with individually is new adjustable. Hot blast connections to the smoldering shaft.

The dry air for the smoldering shaft and the combustion air for the upper fire and for the lower fire is supplied in a heated state.

This dry or combustion air is preheated in the dust cleaner or cooler for the hot, constant material combing from the gas generator Gas.

The use of heated dry air for the smoldering shaft is at inferior fuels, which usually have a high moisture content, particularly advantageous. The same is true for preheating the combustion air for the top fire and of lasting benefit to the underfire in so far as the burning thereby is accelerated and by the accelerated combustion also the conversion of the inconsistent gases to persistent gases takes place faster.

The accelerated combustion brings a corresponding increase the performance of the carburetor and an improvement in the gas value with it.

The use of heated combustion air is with gas generators known. In these, however, it does not have the special meaning that it has in the Application for the smoldering shaft and for the upper fire according to the invention comes.

In the drawing, the subject matter of the invention is shown, for example.

A is the coal feed, b the ring-shaped inlet for hot dry air to the smoldering shaft, c the ring-shaped inlet for hot combustion air to the upper fire, d the ring-shaped collector for the constant gas, e the central inlet for hot combustion air to the lower fire, f the ring-shaped hot air duct , g the adjustable hot air supply to the lower fire, h the adjustable hot air line to the upper fire, i the adjustable hot air line to the smoldering shaft, k. the gas generator shaft, l the line of the constant gas to the cooler.

As usual, the gas generator is operated by induced draft.
