Method for grading and conditioning coal by stable obtained coke oven smoke

The invention discloses a method of steadily obtaining coke oven smoke for coal classification and moisture control, and is characterized in that: a waste gas extraction point of a coke oven flue is selected, frequency conversion control of a draught fan is done to obtain the waste gas in the coke oven flue for realizing the airflow classification and moisture control of the coking coal, the high temperature waste gas is maximally obtained under the premise of assuring the stability of the suction of the coke oven flue. The method steadily obtains the coke oven smoke as the gas medium of classification and moisture control in the pre-treatment of the coking coal while the production of the coke oven is not affected, and is applied in the waste energy utilization of the coke oven waste gas in the coking industry.

Real-time control method for coal gas dynamic balancing in steel plants based on cabinet position prediction

A cabinet-based prediction method for the real-time control of the gaskinetic equilibrium in the steel enterprise, relating to the real-time control technique for the kinetic equilibrium of the by-product gas in the steel enterprise; the utility model is used to solve the off-balance between the supply and demand of the gas system for a short period of time. As the detection technique and the control medium of the automatic gas system are perfected, the operator can fully control the operating condition of the gas system, including the main pipeline pressure, the flow, the user flow, the conveyer equipment and the storage facility. Meanwhile, the regression model is adopted to forecast the future developing trend of the gas system as per the real operation data and the estimation on the main performance currently. Furthermore, based on the balance-related experiences of the site operator, the system will dynamically give out the operating recommendation concerning the adjustable gas use ...

Heat value stabilizing control system of mixed gas and computer-controlled model

Transforming plant intelligent electronic equipment access system

A system used for connecting with the intelligent electronic equipment in the transformer substation, so as to realize the tele-mechanics transmission of ''four remote'' date for the equipment in the transformer substation. The system adds a communication layer between the equipment in the isolated layer and the monitored control system of the transformer substation. The communication layer adopts the communication supervisor which is constituted by the high performance embedded system. Simultaneously, the data acquisition for the site equipment RS 485channel is completed and the communication protocol conversion is finished for the Ethernet transmission. Also, both the two-equipment and the double-channel redundancy communication can be realized to improve the reliability of data acquisition and communication as well as guarantee the reliability and the real time of the electric system's tele-mechanic data transmission, so as to solve such problems as the access conflict among a plurality ...
