Abstract

The present invention provides a power grid peak-shaving system and method for induction furnace iron bath coal gasification. The system includes a power supply device and an induction furnace. The power supply device is connected to the induction furnace. The induction furnace includes a furnace body and a power supply. An inductor for heating the furnace body. The furnace body is provided with a feeding port, a material nozzle, a gas outlet, and a slag outlet. The material nozzle is arranged on the side wall of the furnace body, and the material nozzle is connected to the side wall of the furnace body. The included angle of the wall is 20°~60°; the power supply device is connected to the power grid. The method is to use the above system to first heat the temperature in the induction furnace to 1400~1550°C; then spray the mixed powder of pulverized coal and calcium carbonate carried by the preheated gasification agent into the induction furnace to carry out the coal gasification reaction; finally, the high temperature Coal gas is used to prepare city gas or chemical products. The invention has the advantages of strong adaptability, no seasonal or regional restrictions, strong peak-shaving ability, fast response, easy control, high energy conversion efficiency, environmental protection and economy.

Description

technical field [0001] The invention relates to comprehensive utilization of power grid electric energy, in particular to a power grid peak regulation system and method for iron bath coal gasification in an induction furnace. Background technique [0002] In recent years, with the change of the power consumption structure of the whole society, the valley-peak difference of major power grids has been increasing day by day, and the peak load of the generator set is difficult to meet the needs of users during the peak period of power consumption, so the power has to be limited. During the valley period, there is an excess of electricity. Due to the unbalanced distribution of grid load over time, the contradiction between the peak-shaving capability of the grid and the objective peak-shaving requirement results in a low utilization rate of the grid load. According to statistics, in 2014, the average annual utilization rate of thermal power equipment above 300,000 kilowatts in m...
