Problems solved by technology

As a result, significant temperature gradients are formed in the unit, which affect the thermochemical reactions in the rotary kiln, which lead to a decrease in the quality of the gases produced and at the same time increase the material stress of the retort, which shortens the its service life

Embodiment Construction

[0039] Figure 1a An example of a lysis device according to an embodiment is shown. In this embodiment, the invention includes a chamber 6' where the thermal cracking of carbonaceous substances takes place. The chamber 6' is a non-rotating plant part and comprises a feedstock inlet 22' at the top and an outlet 23' for solid cracking products at the bottom. Between the inlet 22' and the outlet 23', a holding pan 5' is arranged in the chamber 6'. The holding tray 5' extends across the entire chamber 6'. The tray 5 has a hole 21 ', and the raw material can reach the outlet side of the tray 5' from the inlet side of the tray 5' through this hole. In use, feedstock enters the chamber 6' through the inlet 22'. The chamber 6', and in particular the housing 20' of the chamber, is maintained at the desired temperature to effect lysis. Thus, the material starts to be heated as soon as it enters the chamber 6'. The raw material falls from the inlet 22' to the holding tray 5'. The m...

Abstract

The invention provides a pyrolysis (or gasification) apparatus for the pyrolysis of fuel, comprising: a static pyrolysis chamber comprising an inner surface defining a fuel contact surface, wherein the chamber is configured to be heated such that the fuel contact surface is maintained substantially at a desired temperature; the chamber further comprising a fuel inlet 22 and an outlet 23; and fuel transportation means, for moving fuel from the fuel inlet to the outlet, which means comprise: a shelf 5 located within the chamber, below the fuel inlet and above the outlet, to receive fuel failing from the fuel inlet, the shelf defining a hole 21 adjacent to the fuel contact surface; and a fuel contact member 8 configured to move fuel over the shelf towards the fuel contact surface until the fuel falls through the hole in said shelf. Advantages of the invention include a reduction in manufacturing and maintenance costs, increased levels of safety of a pyrolysis gasifier and an improved gas product quality.

Description

technical field [0001] The invention relates to a plant for the gasification process of carbonaceous substances. The gasification process involves cracking (also known as "devolatilisation") on a carbonaceous fuel. Background technique [0002] Pyrolysis involves thermal splitting of carbon chains (raw materials) in the absence of oxygen. The thermal cracking process essentially breaks down the feedstock into three parts: gas, oil and carbon char. These products can be widely used in various fields. However, cracking units are generally expensive and complex. [0003] The more common cracking unit is the rotary kiln type, which requires a very complicated gas seal to prevent air from entering the rotary cracking chamber to prevent risks such as explosion and flashback. In a rotary kiln unit, the furnace body actually rotates along a horizontal axis, and gravity causes the raw material to descend into the lower part of the kiln. Therefore, the upper part of the rotary ki...
