Embodiment Construction

[0017] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0018] Such as figure 1 As shown, the present invention provides an experimental device for preventing high-alkali coal coking and contamination research, including a pulverizing system, a combustion system, a water system, an air system, and an experimental measurement system. The pulverizing system includes: raw coal bunker 5, coal feeder 4, coal mill 3, pulverized coal bunker 2, pulverized exhaust fan 1, and cold air pipeline 7. Coal feeder 4 sends the raw coal in raw coal bunker 5 to the coal mill Machine 3, coal mill 3 are communicated with cold air pipeline 7 and pulverized coal bin 2, pulverized coal bin 2 is communicated with exhaust fan 1, and exhaust fan 1 is communicated with powder delivery pipeline. Combustion system includes: combustion furnace 9, auxiliary layer combustion furnace 11, vertical furnace 23, ignition ...

Abstract

The invention relates to an experiment device for research on coking and contamination prevention of high alkali coal, the experiment device is characterized by including a coal pulverizing system and a combustion furnace, the coal pulverizing system is used for pulverizing raw coal into pulverized coal, and the combustion furnace is at least provided with a vertical hearth and a horizontal flue. The experiment device aims at some very special kind of coal with serious coking and contamination problems and the characteristics that boilers in the prior art are much lack in operating experience on combustion of the very special kind of coal, and discloses the experiment device for coking and contamination prevention of high alkali coal taking Zhundong coal as a representative, through the experiment device, the purposes of mastering the combustion mechanism, ignition mechanism, and characteristics of heat transfer, coking and contamination of the special kind of coal can be achieved, and the optimization scheme for the design and application of a large power station boiler can be provided.

Description

technical field [0001] The invention relates to an experimental device for preventing high-alkali coal (especially Xinjiang Zhundong coal) from coking and contamination research. Background technique [0002] It is a narrow strip from Fukang City to Mulei Kazakh Autonomous County in the east of the Junggar Basin in Xinjiang, about 220 kilometers from east to west. The Zhundong Coalfield has a predicted reserve of 390 billion tons of resources, and the current cumulative proven reserves of coal resources are 213.6 billion tons. It is currently the largest integrated coal field in my country. [0003] At present, the coal produced in the Zhundong mining area is mainly used for power generation and civil use. Due to the limitation of coal resources around Urumqi, more and more power plants built in Xinjiang that do not use Zhundong coal have begun to mix Zhundong coal, and more and more Zhundong coal is directly used as the design coal for new power plants. Due to the extensi...
