METHOD FOR MAINTAINING SPECIFIED GASIFICATION MODE OF COAL-WATER SLURRY

摘要

FIELD: power industry.;SUBSTANCE: coal-water slurry is supplied through atomisers to gas generator 1. In order to create the pressure required for injection of coal-water slurry, water vapour is used. Supply speed of coal-water slurry is measured by means of installation of temperature sensor 6 and pressure sensors 7 are installed and measurements of composition of obtained generator gas 8 are made to control oxygen supply. Measured values are compared to the appropriate data meeting the optimum gasification method, and the appropriate signals are fed to flow sensors of coal-water slurry 2, steam 4 and oxygen 3 for their correction.;EFFECT: invention allows controlling the gasification process of coal-water suspension.;1 dwg
