Intelligent four-path high efficiency power coal burner

Abstract

The invention relates to a intelligent four-channel high efficient coal powder burner comprising four-channel combustion train and its intelligent control device which contains computer control module, high temperature thermocouple, wind speed measuring apparatus and tunable wind rate physical construction. The wind speed measuring apparatus is layout in the four-channel combustion train, high temperature thermocouple are layout on several key points reflecting cement firing state, thermoelectricity signal collected being transferred thermoelectricity signal to computer control module by cable, then the tunable wind rate physical construction adjusts wind rate automatically after receiving signal disposed. The invention applies the present high efficient burner to new style cement industrial production in the fluctuating condition of fluctuation of material and fuel, decreasing the possibility of skin formation blockage greatly.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an intelligent four-channel high-efficiency pulverized coal burner, which is mainly used for the kiln head or kiln tail coal pulverized burner of cement and related industrial rotary kilns. Background technique [0002] The modern cement industry has entered the development stage of the new dry process rotary kiln marked by pre-calcining technology, and the burner corresponding to the kiln system has always been one of the key supporting equipment. In recent years, the use of three-channel and four-channel burners in new dry process kilns has become increasingly common. However, on the one hand, due to the weak technical force of the general cement plant, there is a lack of knowledge about the burner; on the other hand, due to the complex and changeable coal quality in our country, not only the utilization efficiency of the burner is low, but also the quality of the cement is ...

AI Technical Summary

Problems solved by technology

But the actual situation is: in many factories, skinning and clogging caused by changes in raw materials and fuels and unreasonable use of burners occur from time to time; at the same time, the ignition of the burner after the factory overhaul is not a constant process

Therefore, only optimizing the structure of the burner and adjusting the process parameters of the burner is far from meeting the requirements of actual cement production.
