Embodiment Construction

[0027] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0028] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0029] An internal heating type forced heat transfer fluidized bed coking coal humidity control process includes: coal crushing steps, drying steps and dust removal steps. Coal pulverizers are used for crushing, and electrostatic precipitators are used for dust removal. In the drying step, the flue gas is used as the heating heat source, and the drying is mainly completed by supplementary combustion type feed water preheater, feed water prehe...

Abstract

The invention discloses a coking coal damping process for an internal-heating type forced heat transferring fluidized bed, which comprises the following steps: smashing coal, drying and dedusting. The invention has the advantages that the system is simple; the operation is reliable; the dehumidification can be controlled and adjusted reliably and flexibly; and electric energy and basic construction investment are saved.

Description

technical field [0001] The invention relates to a coking technology, in particular to an internal heating forced heat transfer fluidized bed coking coal humidity control process. Background technique [0002] Coal humidity control process (CMC) refers to the process of "moisture control of coal for coking and charging furnace". It is developed on the basis of dry coal coking technology. , dehydration, to achieve the adjustment and control of coal moisture. According to the current coking process requirements, the moisture in coal is controlled at about 6%, so as to reduce the energy consumption of the coking process, ensure the stability of coke oven operation, improve the quality of coke or increase the weak The purpose of adding the amount of caking coal and reducing the amount of coking sewage. At the same time, the moisture content of the coking coal in the furnace is reduced, and the bulk density of the coal is increased, which correspondingly increases the coke output...
