Embodiment 1

[0058] The cold state simulation of the coking process of the heating surface in the incinerator under the actual production situation, such as the flow diagram Figure 1 As shown, the experimental apparatus is as follows Figure 2-3 as shown.

[0059] In the present embodiment, the circulation channel is a ring pipe structure having two main pipes 1, the main pipe 1 is a transparent cylindrical tube, and any one of the main pipes 1 is located at the top of the other main pipe 1, in fact, the circulation channel 1 uses a transparent cylindrical ring describer, which is a closed ring pipe, has good sealing and is convenient to observe the progress of the reaction.

[0060] The injection channel comprises the injection port 3, the injection port 3 is connected to the main pipe 1 through the first injection pipe 4 and is connected, the injection port 3 is a funnel-shaped structure, the injection port 3 and the first injection pipe 4 are higher than the circulation channel as a whole, ...

Embodiment 2

[0076] As in Example 1, the difference is that the reaction structure 14 is added to the reaction assembly in step (6) as a precipitate structure (Fe bar).

[0077] The results showed that during the cold simulation, the surface of the Fe rod was covered with a layer of red substance, and the solution changed from blue to light green.

Embodiment 3

[0079] With Example 1, the difference is that in step (3) a solute (AgNO) is added to the solvent 3 Step (6) Add reaction structure 14 as the precipitate structure (Cu rod) to the reaction assembly.

[0080] The results showed that during the cold simulation, the surface of the Cu sheet was covered with a layer of silvery-white substance, and the solution changed from colorless to blue.

Abstract

The invention relates to the field of energy and environment crossing, in particular to a cold state simulation method and device for the coking process of a heating surface of an incinerator. After the cold state simulation device is filled with the solution dissolved with the solute, the solution circularly flows in the cold state simulation device, then the precipitation structure is added, and the precipitation generation amount is observed. In the scheme of the invention, the cold state simulation device is filled with the solvent in which the solute is dissolved so as to achieve the effect of simulating flue gas, then the solute and the precipitation structure react in the cold state simulation device to generate the precipitate, and the coking generation process of the heating surface of the incinerator is simulated, so that the technical purpose of simulating the coking process of the heating surface of the incinerator in a cold state is achieved. The problems that in industrial production application, the coking process of the heating surface of the incinerator is difficult to realize in an experiment and the coking process of the heating surface of the incinerator is difficult to observe in the experiment are solved, and a new solution thought is provided for guiding production practice through coking cold-state simulation.

Description

Technical field [0001] The present invention relates to the intersection of energy and environment, specifically to a cold state simulation method and apparatus for the coking process of the heating surface of an incinerator. Background [0002] The problem of ash coking in the incinerator is caused by many complex factors, such as fuel characteristics, aerodynamic field in the furnace, the geometry of the furnace cavity, the layout and structural characteristics of the burner, the size of the incinerator, the chemical composition of the incinerator, etc. will affect the coking situation in the furnace. Incinerator ash coking is a very complex physicochemical process, which involves the combustion of materials, heat transfer in the furnace, mass transfer, the potential slagging tendency of the material, the movement of ash particles in the furnace and the adhesion between the ash and the pipe wall, and other complex processes, and there is no mathematical model that can quantita...
